AFNetworking Get full http response - ios

Question

I am querying my server using AFNetworking, the latest - to date - version.
My server side PHP is sending a PHP related error but I am unable to see what the error is ( so I can debug it) as AFNetworking is expecting a JSON.
Could anyone tell me how could I see the full HTTP result. I've researched and I know is something to do with operation.responseString inside the success / fail block my current block does not have AFHTTPRequestOperation* operation and I can't add it as another block variable somehow.
I would really appreciate some help.
The following code uses
NSURL *url = [[NSURL alloc]initWithString:URL];
AFHTTPClient *httpClient = [[AFHTTPClient alloc]initWithBaseURL:url];
NSURLRequest *request = [httpClient multipartFormRequestWithMethod:#"POST" path:URLPATH parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
//...
}
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request
success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON){
NSLog(#"Inside the success block %#",JSON);
[[self delegate ]shareExerciseDone:JSON];
[[self delegate] activityIndicatorFinish];
}
failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON){
NSLog(#"Response text is: %#", operation.responseString);
NSLog(#"json text is: %#", JSON);
NSLog(#"Request failed with error: %#, %#", error, error.userInfo);
[[self delegate] activityIndicatorFinish];
}];
[operation start];
The error
Request failed with error: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0xc1b4520 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}, {
NSDebugDescription = "JSON text did not start with array or object and option to allow fragments not set.";

Don't use AFJSONRequestOperation, just use AFHTTPRequestOperation.

For Uploading Images From iOS to Server i am using Afnetworking
can you try with this Code.and you will get response in success or failure.
NSData *userImgToUpload = UIImagePNGRepresentation(userImg.image);
NSURL *url = [NSURL URLWithString:#"www.domainname.com"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSLog(#"%#",#"Uploading data");
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:usernameTxt.text,#"username", firstnameTxt.text,#"first_name",lastnameTxt.text,#"last_name", nil];
// Upload Image
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:#"POST" path:#"/addPatient" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:userImgToUpload name:#"patientimage" fileName:[NSString stringWithFormat:#"%#.png",usernameTxt.text] mimeType:#"image/png"];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"response: %#",[operation.responseString objectFromJSONString]);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Upload Failed");
NSLog(#"error: %#", [operation error]);
}];
[operation start];

You should listen for the AFNetworkingOperationDidStartNotification and AFNetworkingOperationDidFinishNotification events that fire at the beginning and end of the operation:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(YourOperationStartMethod:)
name:AFNetworkingOperationDidStartNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(YourOperationFinishMethod:)
name:AFNetworkingOperationDidFinishNotification
object:nil];
You can grab the operation object from the notification like this:
AFHTTPRequestOperation *operation =
(AFHTTPRequestOperation *) [notification object];
This operation object contains request and response properties.
A good example of how all this works can be found in the AFHTTPRequestOperationLogger plugin (which, of course, you could simply use, instead of writing your own thing).
