Image upload using AFMultipartFormData AFNetworking 3.0

问题:

NSURL *URL = [NSURL URLWithString:@"some APi"];  AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; manager.responseSerializer = [AFHTTPResponseSerializer serializer];  UIImage *myImageObj = [UIImage imageNamed:@"avatar.jpg"]; NSData *imageData= UIImagePNGRepresentation(myImageObj);  [manager POST:URL.absoluteString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {     [formData appendPartWithFileData:imageData                                 name:@"file"                             fileName:@"avatar.jpg" mimeType:@"image/jpeg"];      // etc. } progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {     NSLog(@"Response: %@", responseObject); } failure:^(NSURLSessionDataTask *task, NSError *error) {     NSLog(@"Error: %@", error); }]; 

I am trying to upload image using afnetworking 3.0 but getting this error every time

Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: internal server error (500)" UserInfo={com.alamofire.serialization.response.error.response= { URL: Some URL } { status code: 500, headers { "Access-Control-Allow-Origin" = "*"; "Content-Length" = 291; "Content-Type" = "text/html"; Date = "Thu, 26 Jan 2017 11:41:19 GMT"; Server = "Werkzeug/0.11.11 Python/2.7.12"; } },

luckily postman provide objective-C and some other languages code but with AFNetworking i used this

    NSURL *URL = [NSURL URLWithString:@"your URL"];      UIImage *myImageObj = [UIImage imageNamed:@"image.jpg"];     NSData *imageData= UIImageJPEGRepresentation(myImageObj, 0.6);      AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];     //manager.responseSerializer=[AFJSONResponseSerializer serializer];     manager.requestSerializer = [AFHTTPRequestSerializer serializer];     manager.responseSerializer = [AFHTTPResponseSerializer serializer];      [manager.requestSerializer setValue:@"multipart/form-data" forHTTPHeaderField:@"Content-Type"];      [manager POST:URL.absoluteString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {         [formData appendPartWithFileData:imageData                                     name:@"file"                                 fileName:@"image.jpg" mimeType:@"image/jpeg"];          // etc.     } progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {         NSLog(@"Response: %@", responseObject);          NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];         NSLog(@"%@",string);      } failure:^(NSURLSessionDataTask *task, NSError *error) {         NSLog(@"Error: %@", error);     }];
