Tips

simple request

2.x

    AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init];
    [manager POST:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
        onSuccess();
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        onFailed(error);
    }];

3.x

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager POST:url parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        onSuccess();
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        onFailed(error);
    }];

Get status code in failure callback

2.x

failure:^(AFHTTPRequestOperation *operation, NSError *error) {  
        onFailed([AppError readErrorResponse:operation error:error], [operation.response statusCode]);
    }

3.x

NSHTTPURLResponse *response = error.userInfo[AFNetworkingOperationFailingURLResponseErrorKey];  
response.statusCode;  

"PUT" MultipartForm Request

2.x

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    NSMutableURLRequest *request = [manager.requestSerializer multipartFormRequestWithMethod:@"PUT" URLString:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            [formData image name:@"image" fileName:@"test.jpg" mimeType:@"image/jpeg"];
        }
    } error:nil];
    AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"success");
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"%@", error);
    }];
    [manager.operationQueue addOperation:operation];

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    NSMutableURLRequest *request = [manager.requestSerializer multipartFormRequestWithMethod:@"PUT" URLString:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        if (image) {
            [formData image name:@"image" fileName:@"test.jpg" mimeType:@"image/jpeg"];
        }
    } error:nil];

    [[manager dataTaskWithRequest:request completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {        
        if (!error) {
            NSLog(@"success");
        } else {
            NSLog(@"Error: %@", error);
        }
    }] resume];
