Objective-C Question

The data couldn't be read because it isn't in the correct format."

Request image from postman[![response image from postman]2I am using AFNetworking to send data to server.Below is my code:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
[manager setResponseSerializer:[AFJSONResponseSerializer serializer]];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];


NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];

[dict setValue:[[arrLoginDetails objectAtIndex:0] objectForKey:@"id"] forKey:@"user_id"];

[dict setValue:[[arrLoginDetails objectAtIndex:0] objectForKey:@"id"] forKey:@"shipper_id"];

[dict setValue:strUuid forKey:@"imageOrderId"];

[dict setValue:@"1" forKey:@"type"];

NSData * imageData = UIImageJPEGRepresentation([aryImages objectAtIndex:0], 0.7);


if([imageData length]>0){
NSString *base64String = [imageData base64EncodedStringWithOptions:0];


if([base64String length]>0){
[dict setValue:base64String forKey:@"file_path"];

NSString * reqFormat= [NSString stringWithFormat:@"%@&email=%@&dev_id=%@",UploadImage,[[arrLoginDetails objectAtIndex:0] objectForKey:@"email"],APP_DELEGATE.stringDeviceID];

[manager POST:reqFormat parameters:dict1 success:^(AFHTTPRequestOperation *operation, id responseObject)
{
}failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(@"error:%@",error.debugDescription);

}


Below is the error I am getting:

The data couldn't be read because it isn't in the correct format.

Error:

Error:Error Domain=NSCocoaErrorDomain Code=3840 "No value." UserInfo={NSDebugDescription=No value.}

If I nslog error.debugdescription iam getting as "The data couldn't be read because it isn't in the correct format."

Please help me to solve this error.

Thank you.

Answer

Try below code:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setStringEncoding:NSUTF8StringEncoding];

manager.requestSerializer=serializer;
manager.responseSerializer.acceptableContentTypes= [NSSet setWithObjects:@"text/html",@"application/json", nil];

 [manager POST:reqFormat parameters:dict1 progress:nil success:^(NSURLSessionTask *task, id responseObject)
     {
         //Print response
     } failure:^(NSURLSessionTask *operation, NSError *error) {
         //Print error
     }];

In AFNetworking 3.0 AFHTTPRequestOperationManager is replaced with AFHTTPSessionManager.
