AFNetworking 2 - post request- add simple text to body - ios

This is my first post in here and is not a repost, I have searched a lot in Stack Overflow for the answer, but without luck... The problem that I'm having is an intermittent error: "request body stream exhausted" with the code:-1021, I'm using AFNetworking 2.
This is what I use to create a RequestOperationManager:
- (AFHTTPRequestOperationManager *)createDefaultManager {
AFHTTPRequestOperationManager *postRequest = [[AFHTTPRequestOperationManager alloc]initWithBaseURL:[NSURL URLWithString:#"myURL"]];
postRequest.securityPolicy.allowInvalidCertificates = YES;
postRequest.responseSerializer = [AFXMLParserResponseSerializer serializer];
[postRequest.requestSerializer setValue:#"Keep-Alive" forHTTPHeaderField:#"Connection"];
[postRequest.requestSerializer setValue:#"text/xml" forHTTPHeaderField:#"Content-Type"];
[postRequest.requestSerializer setValue:#"en-US" forHTTPHeaderField:#"Content-Language"];
return postRequest;
}
Here is my post method:
- (void)postRequest:(AFHTTPRequestOperationManager *)request withURL:(NSString *)url withBody:(NSString *)body {
[request POST:url parameters:nil constructingBodyWithBlock:^(id <AFMultipartFormData>formData)
{
[formData throttleBandwidthWithPacketSize:kAFUploadStream3GSuggestedPacketSize
delay:kAFUploadStream3GSuggestedDelay];
NSMutableDictionary *mutableHeaders = [NSMutableDictionary dictionary];
[mutableHeaders setValue:[NSString stringWithFormat:#"text/xml"] forKey:#"Content-Type"];
[mutableHeaders setValue:[NSString stringWithFormat:#"any-value"] forKey:#"User-Agent"];
[formData appendPartWithHeaders:mutableHeaders body:[NSData dataWithBytes:[body UTF8String] length:[body length]]];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
[self connectionSuccess:operation withResponse:responseObject];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[self connectionFailed:operation withError:error];
NSLog(#"Here's the request: %#", operation.request.HTTPBody);
}];
}
I don't know what is wrong in what I'm doing. That should work all the time.
Thanks,
JJ

How to add header in Multipart Form data request iOS?

Following is my code snippet. I am getting an error while runnning this code. I have added headers as part of the request. Is that the correct way ?
__block int i=1;
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:url]];
NSDictionary *parameters = #{#"wave_Id": [inputDictionary objectForKey:#"wave_Id"]};
AFHTTPRequestOperation *op = [manager POST:url parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
for(NSData *imageData in [inputDictionary objectForKey:#"images"])
{
[formData appendPartWithFileData:imageData name:[NSString stringWithFormat:#"file%d",i] fileName:[NSString stringWithFormat:#"abc%d.png",i] mimeType:#"image/png"];
i++;
}
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:0 error:&error];
NSAssert(jsonData, #"Failure building JSON: %#", error);
NSLog(#"Json Data Image Upload %#",jsonData);
NSAssert(jsonData, #"Failure building JSON: %#", error);
NSString *token = [SSKeychain passwordForService:RegistrationTokenKey account:LoggedInUserKey];
NSDictionary *jsonHeaders = #{#"Content-Disposition" : #"form-data; name=\"parameters\"",
#"Content-Type" : #"application/json",
#"Accept" : #"application/json",
#"Authorization" : token};
[formData appendPartWithHeaders:jsonHeaders body:jsonData];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[op start];
I need your complete method to be 100% sure, but please try writing this way and see if it helps:
__block int i = 1;
NSMutableArray *mutableOperations = [NSMutableArray array];
NSDictionary *parameters = #{#"wave_Id": [inputDictionary objectForKey:#"wave_Id"]};
for (NSData *imageData in [inputDictionary objectForKey:#"images"]) {
NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:#"POST"
URLString:url
parameters:parameters
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData
name:[NSString stringWithFormat:#"file%d",i]
fileName:[NSString stringWithFormat:#"abc%d.png",i]
mimeType:#"image/png"];
i++;
}
error:nil];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[mutableOperations addObject:operation];
}
NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:mutableOperations progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {
NSLog(#"%lu of %lu images uploaded!", numberOfFinishedOperations, totalNumberOfOperations);
} completionBlock:^(NSArray *operations) {
NSLog(#"All images have been uploade!");
}];
[[NSOperationQueue mainQueue] addOperations:operations waitUntilFinished:NO];
Actually I modified the same code and its working now. Changed the "Content-Type" to "multipart/form-data".
Also added the key (parameter name) for my imagesArray in the API request to the following method
"formData appendPartWithFileData:imageData name:#"yourKey"..."
if (_isUploadImage) {
__block int i=1;
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:url]];
[manager.requestSerializer setValue:#"multipart/form-data" forHTTPHeaderField:#"Content-Type"];
[manager.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Accept"];
if (_shouldBeInHeader) {
NSString *token = [SSKeychain passwordForService:RegistrationTokenKey account:LoggedInUserKey];
[manager.requestSerializer setValue:[NSString stringWithFormat:#"Token %#",token] forHTTPHeaderField:#"Authorization"];
}
NSDictionary *parameters = #{#"wave_id": [inputDictionary objectForKey:#"wave_id"]};
AFHTTPRequestOperation *op = [manager POST:url parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
for (NSData *imageData in [inputDictionary objectForKey:#"images"])
{
[formData appendPartWithFileData:imageData name:[NSString stringWithFormat:#"images"] fileName:[NSString stringWithFormat:#"abc%d.png",i] mimeType:#"image/png"];
i++;
}
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failed");
}];
[op start];
}

Image Uploading in iOS

currently i am working on image uploading in ios application and here is my code
AFHTTPRequestOperationManager *man = [[AFHTTPRequestOperationManager alloc]init];
man.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
NSData *imageData = UIImagePNGRepresentation(self.imageView.image);
AFHTTPRequestOperation *op = [man POST:AddGroup parameters:#{ #"userid":#"6",
#"name":self.txtGroupName.text
#"description":self.textViewGroupDescription.text,
#"image":imageData }
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"image" fileName:filename mimeType:#"image/png"];
}
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"Success: %# ***** %#", operation.description, operation.responseString);
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Imani" message:#"New Group Succesfully Created.." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil] ;
[alertView show];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[op start];
now i am getting response from successfully from json but image data are passing null in to server any one have idea ?
Thank you.
try this cede to upload image on server.
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"your api link"]];
NSData *imageData = UIImageJPEGRepresentation(self.imgPost.image, 0.5);
NSDictionary *parameters = #{#"param": #"value",
#"param2" : #"value2"
};
AFHTTPRequestOperation *op = [manager POST:#"/api/store/posts/format/json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//do not put image inside parameters dictionary as I did, but append it!
[formData appendPartWithFileData:imageData name:#"file" fileName:[NSString stringWithFormat:#"njoyful_%f.jpg",[NSDate timeIntervalSinceReferenceDate]] mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[op start];
I'm not familiar with AFHTTPRequestOperation so i'll just give you something i'm using that creates json request.
- (NSURLRequest *)convertToRequest:(NSString *)stringURL withDictionary:(NSDictionary *)dictionary
{
NSError *error = nil;
NSData *JSONData = [NSJSONSerialization dataWithJSONObject:dictionary options:0 error:&error];
NSURL *url = [NSURL URLWithString:stringURL];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setHTTPBody: JSONData];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept-Encoding"];
[request setValue:[NSString stringWithFormat:#"%lu", (unsigned long)[JSONData length]] forHTTPHeaderField:#"Content-Length"];
return request;
}
Please check my answer here
This also work for multi image upload. Cheers! :)

POST JSON string in request body (not in URL-Form-Encoded Request) AFNetworking

I want to send a JSON String to server using AFNetworking POST request.
Currently I am trying following code
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
NSData * data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];
[request setTimeoutInterval:120];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject)
{ NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %#", error);
}];
[operation start];`
Nothing is happening. The code neither enters success block nor the failure block. What can be the reason? Is there any alternate way of doing this in AFNetworking 2.
NOTE: Request is working perfectly on POSTMAN and returns response in less than 500 ms.
This is working code of mine
NSDictionary *parameters = [NSDictionary dictionary];//set values here
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init];
[manager POST:#"http://example.com/api" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
//Do success code
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//do failure code
}];
This is the function which configure HTTP body AFJSONRequestSerializer
#pragma mark - AFURLRequestSerialization
- (NSURLRequest *)requestBySerializingRequest:(NSURLRequest *)request
withParameters:(id)parameters
error:(NSError *__autoreleasing *)error
{
NSParameterAssert(request);
if ([self.HTTPMethodsEncodingParametersInURI containsObject:[[request HTTPMethod] uppercaseString]]) {
return [super requestBySerializingRequest:request withParameters:parameters error:error];
}
NSMutableURLRequest *mutableRequest = [request mutableCopy];
[self.HTTPRequestHeaders enumerateKeysAndObjectsUsingBlock:^(id field, id value, BOOL * __unused stop) {
if (![request valueForHTTPHeaderField:field]) {
[mutableRequest setValue:value forHTTPHeaderField:field];
}
}];
if (parameters) {
if (![mutableRequest valueForHTTPHeaderField:#"Content-Type"]) {
[mutableRequest setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
}
[mutableRequest setHTTPBody:[NSJSONSerialization dataWithJSONObject:parameters options:self.writingOptions error:error]];
}
return mutableRequest;
}
You are using AFJSONRequestSerializer as request serializer and it is meaning, you are sending JSON string from NSDictionary as HTTP body
[mutableRequest setHTTPBody:[NSJSONSerialization dataWithJSONObject:parameters options:self.writingOptions error:error]];
}
So you all need to do is make NSDictionary from JSON values, and call as above.
No need to make JSON string.

How to make an HTTP request with AFNetorking and NSURLRequest?

I am trying to use AFHTTPRequestOperationManager to make an HTTP request. I need to use AFHTTPRequestOperationManager because I want to be able to cancel all operations if necessary. I can't get this working for some reason. The completion blocks aren't called. Am I missing something?
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://twitter.com/%#", username]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:#"MyUserAgent (iPhone; iOS 7.0.2; gzip)" forHTTPHeaderField:#"User-Agent"];
[request setHTTPMethod:#"GET"];
[self.manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *html = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
if ([html containsString:#"var h = decodeURI(l.hash.substr(1)).toLowerCase();"]) {
completion(YES, nil);
} else {
completion(NO, nil);
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
completion(NO, error);
}];
This is working code, you need to use GET or POST method there.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"email":emailfield.text};
[manager GET:#"http://example.com/api" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
While everyone else is right -- you should be using the modern AFNetworking constructs instead of the legacy features -- there is a quick way to get done what you're looking to get done.
By the looks of it, the method - (??? *) HTTPRequestOperationWithRequest:success:failure likely returns an AFHTTPRequestOperation. If I'm correct, you just need to actually start the operation. See below for your code, corrected.
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://twitter.com/%#", username]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:#"MyUserAgent (iPhone; iOS 7.0.2; gzip)" forHTTPHeaderField:#"User-Agent"];
[request setHTTPMethod:#"GET"];
AFHTTPRequestOperation *op = [self.manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *html = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
if ([html containsString:#"var h = decodeURI(l.hash.substr(1)).toLowerCase();"]) {
completion(YES, nil);
} else {
completion(NO, nil);
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
completion(NO, error);
}];
[op start];
HTTPRequestOperationWithRequest method returns AFHTTPRequestOperation. You have to add it to some operation queue to start it. For example
AFHTTPRequestOperation *operation = [self.manager HTTPRequestOperationWithRequest:request .........
[[NSOperationQueue currentQueue] addOperation:operation];
You can use AFHTTPSessionManager which is a little better than AFHTTPRequestOperationManager and cancel requests using method cancel of NSURLSessionDataTask. You can find some code examples here - AFNetworking 2.0 cancel specific task
Check this will work
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"application/json", nil];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager POST:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];

send image along with other parameters with AFNetworking

I am updating an old application code which used ASIHTTPRequest with AFNetworking. In my case, I am sending a bench of data to API, these data are different types: Image and other.
Here is the code I adopt so far, implementing an API client, requesting a shared instance, prepare the params dictionary and send it to remote API:
NSMutableDictionary *params = [NSMutableDictionary dictionary];
[params setValue:#"Some value" forKey:aKey];
[[APIClient sharedInstance]
postPath:#"/post"
parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
//some logic
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//handle error
}];
What would be the case when I want to add an image to the params dictionary?
With ASIHTTPRequest, I used to do the following:
NSData *imgData = UIImagePNGRepresentation(anImage);
NSString *newStr = [anImageName stringByReplacingOccurrencesOfString:#"/"
withString:#"_"];
[request addData:imgData
withFileName:[NSString stringWithFormat:#"%#.png",newStr]
andContentType:#"image/png"
forKey:anOtherKey];
I digged into AFNetworking documentation and found they appending the image in an NSMutableRequest like this:
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:#"avatar.jpg"], 0.5);
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:#"POST" path:#"/upload" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData:imageData name:#"avatar" fileName:#"avatar.jpg" mimeType:#"image/jpeg"];
}];
How should I mix this together on a neat way to integrate my image data into the APIClient request? Thanx in advance.
I have used same AFNetworking to upload image with some parameter. This code is fine working for me. May be it will help out
NSData *imageToUpload = UIImageJPEGRepresentation(uploadedImgView.image, 1.0);//(uploadedImgView.image);
if (imageToUpload)
{
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:keyParameter, #"keyName", nil];
AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:#"http://------"]];
NSMutableURLRequest *request = [client multipartFormRequestWithMethod:#"POST" path:#"API name as you have" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData: imageToUpload name:#"image" fileName:#"temp.jpeg" mimeType:#"image/jpeg"];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
//NSLog(#"response: %#",jsons);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
if([operation.response statusCode] == 403)
{
//NSLog(#"Upload Failed");
return;
}
//NSLog(#"error: %#", [operation error]);
}];
[operation start];
}
Good Luck !!
With AFNetworking 2.0.1 this code worked for me.
-(void) saveImage: (NSData *)imageData forImageName: (NSString *) imageName {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSString *imagePostUrl = [NSString stringWithFormat:#"%#/v1/image", BASE_URL];
NSDictionary *parameters = #{#"imageName": imageName};
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:#"POST" URLString:imagePostUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"image" fileName:imageName mimeType:#"image/jpeg"];
}];
AFHTTPRequestOperation *op = [manager HTTPRequestOperationWithRequest:request success: ^(AFHTTPRequestOperation *operation, id responseObject) {
DLog(#"response: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
DLog(#"Error: %#", error);
}];
op.responseSerializer = [AFHTTPResponseSerializer serializer];
[[NSOperationQueue mainQueue] addOperation:op];
}
If JSON response is needed use:
op.responseSerializer = [AFJSONResponseSerializer serializer];
instead of
op.responseSerializer = [AFHTTPResponseSerializer serializer];
