I'm using AFNetworking in my iOS project, and this is my code:
NSURL *url = [NSURL URLWithString: [signinUrl stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:signinUrl parameters:dicParam success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSString *myString = [[NSString alloc] initWithData:operation.request.HTTPBody encoding:NSUTF8StringEncoding];
NSLog(#"Error: %#", myString);
}];
This code let to make connection with server correctly and I receive an answer, but I need to catch the code status with their description, I mean... catch something like that:
status_code: 406 custom message
I can get status code but it is an integer, anyone have idea how I can get this custom message?

There are other questions with similar titles but none of them helped me. I've to send a PUT request to server in order to change the status of appointment so I've made this method -(void)appointmentStatusChangedTo:(NSString *)statusID atAppointmentID:(NSString *)appointmentID In which I'm setting the URL and Parameters as
NSString *string = [NSString stringWithFormat:#"%#/API/Appointments/3",BaseURLString];
NSDictionary *para = #{
#"AppointmentStatusId":statusID,
#"ID":appointmentID
};
Then I've made URL request as
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:#"PUT" URLString:string parameters:para error:nil];
After that I'm setting the header for an authorization token as
NSString *token = [NSString stringWithFormat:#"Bearer %#",[[NSUserDefaults standardUserDefaults] objectForKey:#"userToken"]];
[req setValue:token forHTTPHeaderField:#"Authorization"];
So finally I'm calling it as
[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error){
if (!error) {
if (response) {
NSLog(#"Respose Object: %#",responseObject);
[self.patientsAppointmentsTableView reloadData];
}
}
else {
// NSLog(#"Error: %#, %#, %#", error, response, responseObject);
NSLog(#"Error: %#", error.localizedDescription);
}
}] resume];
Now it is successfully sending the data to the server but as a response I'm getting
Error: The data couldn’t be read because it isn’t in the correct
format.
I am not sure what the response might look like at the moment as I'm not in contact with backend guy. But as far as I remember it was just a simple 1. SO kindly tell me how to handle any type of response using AFNetworking 3.0 or any change in my code.
try to use below code:
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setStringEncoding:NSUTF8StringEncoding];
manager.requestSerializer=serializer;
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
Try following code using Afnetworking 3.0
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager GET:url parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"%#",responseObject);
self.responseHandlers(YES,responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
self.responseHandlers(NO,nil);
}];
I've implemented the JSON parsing using AFNetworking many time in some previous apps as:
NSString *string = [NSString stringWithFormat:#"%#?get_all_data", BaseURLString];
NSURL *url = [NSURL URLWithString:string];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
{
//performing parsing here
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//error message displayed here
}
But as of today I started working on an app after a while I came to use AFNetworking again and I installed in using pods so as I write this same code as I use to write before it gives me the error saying Unknown Receiver AFHTTPRequestOperation. Do you mean AFHTTPRequestSerializer?
After searching about it I found that it's AFNetworking 2 or 3 era now and they have somehow changed the scenerio. I didn't find the exact solution on how to implement it now. So can anyone write the code in the answer below that works with the latest version of AFNetworking.
This is the new approach of AFNetworking 3.x to parse data:
NSString *path = #"yourapilink";
NSString *escapedPath = [path stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:escapedPath parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
Hope it help !
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) {
}];
Following code is to submit images through an operationQueue. The requests are all fired one by one correctly, the server response contains the image file name which client needs to get hold of. The problem is that the reponseObject for the success/failure block is not expected parsed JSON but type of NSInLineData shown in debugger. Now I suspect the code to construct the operation from the NSMutableURLRequest caused the issue. Please help.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
NSMutableURLRequest *request = [manager.requestSerializer multipartFormRequestWithMethod:#"POST"
URLString:podURLString parameters:nil
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
NSError *error;
BOOL success =[formData appendPartWithFileURL:imgURL name:#"images" fileName:img.path
mimeType:#"image/jpg" error:nil];
if (!success)
NSLog(#"appendPartWithFileURL error: %#", error);} error:nil];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Image Success: %#", [responseObject description]);
NSString *imagePath = [response objectForKey:#"imageFileName"];
[self.delegate networkManager:self didSubmitDeliveryImageForImageID:imagePath];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Image Error: %#", error);
NSLog(#"image error: %#", [operation.responseObject description]);
NSString *imageFilePath = [operation.responseObject objectForKey:#"imageFileName"];
[self.delegate networkManager:self didFailSubmitDeliveryImageForImageID:imageFilePath];
}];
[manager.operationQueue addOperation:operation];
When you get the response as NSInLineData. It's good to go now. You can write below single line of code to get NSDictionary if it supports json format.
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseObjec options:0 error:nil];
Just add this line of code before your AFHTTPRequestOperation block
**operation.responseSerializer = [AFJSONResponseSerializer serializer];**
I'm using the following code to set up my operation manager:
requestSerializerJson = [AFJSONRequestSerializer serializer];
[requestSerializerJson setValue:[taskHandler getBranchesApiConstantForName:#"header_value_content_type"] forHTTPHeaderField:[taskHandler getBranchesApiConstantForName:#"header_name_content_type"]];
[requestSerializerJson setValue:[taskHandler getBranchesApiConstantForName:#"header_value_api_key"] forHTTPHeaderField:[taskHandler getBranchesApiConstantForName:#"header_name_api_key"]];
httpRequestOperationManager = [AFHTTPRequestOperationManager manager];
httpRequestOperationManager.requestSerializer = requestSerializerJson;
httpRequestOperationManager.responseSerializer = [AFJSONResponseSerializer serializer];
httpRequestOperationManager.operationQueue = [[NSOperationQueue alloc] init];
httpRequestOperationManager.operationQueue.maxConcurrentOperationCount = 1;
Then, I've got a method to download multiple JSON strings:
- (void)downloadBranches {
NSLog(#"Test %#", httpRequestOperationManager.requestSerializer.HTTPMethodsEncodingParametersInURI);
for (NSString *branchUuid in taskHandler.addedBranchesUuids) {
NSString *urlString = [NSString stringWithFormat:#"%#%#%#", urlBase, [taskHandler getBranchesApiConstantForName:#"getbranch_suffix"], branchUuid];
NSURL *URL = [NSURL URLWithString:urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSLog(#"Test %#", request.allHTTPHeaderFields);
AFHTTPRequestOperation *op = [httpRequestOperationManager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[httpRequestOperationManager.operationQueue addOperation:op];
}
}
All the operations are performed but I get a message from the server which says that I didn't supply the authentication key.
I specifically set it in the 3rd line - for the requestSerializerJson which is then added to the httpRequestOperationManager so all of the requests should be using the headers.
I added an NSLog to print request.allHTTPHeaderFields but it says "(null)".
How can I fix this?
downloadBranches is completely bypassing the serializer by building an NSURLRequest manually. The whole point of the serializer is to do that for you.
You need to call requestWithMethod:URLString:parameters: on your serializer, which will return an NSURLRequest with the headers you want.
Or just use the operation manager's GET:… method inside that for loop; your use case doesn't look like it requires this other stuff at all.
