Upload an image(MultipartFormData) request objctiveC - ios

Question

I am trying to send a post request.
Here is my try:
-(void)Test{
NSDictionary * orderMasterDict = #{#"distributorId":#10000,
#"fieldUsersId": #3,
#"itemId":#0,#"orderMatserId":#56358 };
Globals.OrderDetailsArray = [NSMutableArray arrayWithObjects:orderDetailsDictAnatomy,orderDetailsDictTexture,orderDetailsDictTranslucency, nil];
NSData *postData = [NSJSONSerialization dataWithJSONObject:Globals.OrderDetailsArray options:NSJSONWritingPrettyPrinted error:nil];
NSData *postData2 = [NSJSONSerialization dataWithJSONObject:orderMasterDict options:NSJSONWritingPrettyPrinted error:nil];
NSString *jsonString2 = [[NSString alloc] initWithData:postData2 encoding:NSUTF8StringEncoding];
NSString *jsonString = [[NSString alloc] initWithData:postData encoding:NSUTF8StringEncoding];
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];
[_params setObject:jsonString2 forKey:#"orderMaster"];
[_params setObject:jsonString forKey:#"orderDetails"];
[_params setObject:[NSString stringWithFormat:#"3"] forKey:#"userId"];
[_params setObject:[NSString stringWithFormat:#"ALRAISLABS"] forKey:#"subsCode"];
// the boundary string : a random string, that will not repeat in post data, to separate post data fields.
NSString *BoundaryConstant = #"----------V2ymHFg03ehbqgZCaKO6jy";
// string constant for the post parameter 'file'. My server uses this name: `file`. Your's may differ
NSString* FileParamConstant = #"imageUpload";
// the server url to which the image (or the media) is uploaded. Use your server url here
NSURL* requestURL = [NSURL URLWithString:#"http://192.168.0.102:8080/Demo/Test/create"];
// create request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:#"POST"];
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", BoundaryConstant];
[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// add params (all params are strings)
for (NSString *param in _params) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"%#\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}
// add image data

[body appendData:[[NSString stringWithFormat:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:#"--%#--\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// set the content-length
NSString *postLength = [NSString stringWithFormat:#"%lu", (unsigned long)[body length]];

How to make a multipartFormData request?
I tried googling for it, couldn't find any answer suitable for this situation, and thought well .Please help me finding the right solution.
Thanks in advance.

Answer 1

First you change your image in NSData then help of AFNetworking you can post your image.
NSData *data = UIImagePNGRepresentation(yourImage);
imageData = [data base64EncodedStringWithOptions: NSDataBase64Encoding64CharacterLineLength];
Then use this code:
NSMutableDictionary *finaldictionary = [[NSMutableDictionary alloc] init];
[finaldictionary setObject:imageData forKey:#"image"];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST: [NSString stringWithFormat: #"%#%#", IQAPIClientBaseURL, kIQAPIImageUpload] parameters: finaldictionary constructingBodyWithBlock: ^(id<AFMultipartFormData> formData) { }
progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(#"Success response=%#", responseObject);
NSDictionary *responseDict = [NSJSONSerialization JSONObjectWithData: responseObject options: NSJSONReadingAllowFragments error: nil];
NSLog(#"%#", responseDict);
}
failure: ^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(#"Errorrrrrrr=%#", error.localizedDescription);
}
];

By using Alamofire
-(void)CreateOrder{
NSString * urlString = [NSString stringWithFormat:#"YOUR URL"
NSDictionary * orderMasterDict = #{#"distributorId":stakeholderID,
#"fieldUsersId": userID,
#"itemId":#0,#"orderMatserId":#0 };
Globals.OrderDetailsArray = [NSMutableArray arrayWithObjects:orderDetailsDictAnatomy,orderDetailsDictTexture,orderDetailsDictTranslucency, nil];
NSDictionary * consumerDetails = #{#"consumerName":Globals.PatientName,#"consumerReferenceId":Globals.PatientID,#"notes":Globals.PatientNotes,#"cunsumerContacNumber":#"456464654654"};
NSData *postData = [NSJSONSerialization dataWithJSONObject:Globals.OrderDetailsArray options:NSJSONWritingPrettyPrinted error:nil];
NSData *postData2 = [NSJSONSerialization dataWithJSONObject:orderMasterDict options:NSJSONWritingPrettyPrinted error:nil];
NSString *jsonString2 = [[NSString alloc] initWithData:postData2 encoding:NSUTF8StringEncoding];
NSString *jsonString = [[NSString alloc] initWithData:postData encoding:NSUTF8StringEncoding];
//retrieving userId from UserDefaults
prefs = [NSUserDefaults standardUserDefaults];
NSString * userIdString = [prefs stringForKey:#"userID"];
NSDictionary *parameters = #{#"orderMaster": jsonString2, #"orderDetails" : jsonString ,#"userId" : userIdString,#"subsCode" : #"ABC_MDENT"};
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:#"POST" URLString:urlString parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//For adding Multiple images From selected Images array
int i = 0;
for(UIImage *eachImage in selectedImages)
{
UIImage *image = [self scaleImage:eachImage toSize:CGSizeMake(480.0,480.0)];
NSData *imageData = UIImageJPEGRepresentation(image,0.3);
[formData appendPartWithFileData:imageData name:#"imageUpload" fileName:[NSString stringWithFormat:#"file%d.jpg",i ] mimeType:#"image/jpeg"];
i++;
}
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask *uploadTask;
uploadTask = [manager
uploadTaskWithStreamedRequest:request
progress:^(NSProgress * _Nonnull uploadProgress) {
dispatch_async(dispatch_get_main_queue(), ^{
});
}
completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
NSLog(#"responseObject : %#",responseObject);
if (error) {
NSlog(#"error")
} else {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
if ([httpResponse statusCode] == 200) {
resposeStatusCode = [responseObject objectForKey:#"statusCode"];
}else{
NSLog(#"requestError");
}
}
}];
[uploadTask resume]; }
