ios - 使用 AFNetworking 发布图像？

Question

如何使用 AFNetworking 发布图片。我正在使用下面的代码发布图片。但是图片没有上传到服务器。发布图片后，我在结果中得到这个链接“http://thisisswitch.com:8084/SmartSwitchService/UserImages/69684177-4601-4665-8890-5424e3fbff73.png ".

谁能告诉我代码中的问题是什么？

这是我的代码:

    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:BaseUrl]];
     NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:posturl parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFormData:imgData name:@"image"];

    }];

    [httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];
    AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    NSDictionary *dict  = (NSDictionary *)JSON;

    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
    }];
    [operation start];

来自Github read me :

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];

NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"Success: %@ %@", response, responseObject);
    }
}];
[uploadTask resume];
