AFnetworking多部分请求正文为零

我试图通过af 2.0多部分请求将图片上传到服务器，但似乎正文总是为空。 这是代码的快照：

[self POST:path parameters:params constructingBodyWithBlock:^(id formData) { [formData appendPartWithFormData:file name:@"file"]; } success:^(NSURLSessionDataTask *task, id responseObject) { andAPIResponseType:apiResponseType]; } failure:^(NSURLSessionDataTask *task, NSError *error) { }]; 

文件是我从设备相机拍摄的照片，并做了类似的事情

  NSData *file = UIImageJPEGRepresentation(avatar, 0.5) 

但是，当我记录我通过AF记录器发送的内容时，我会得到类似的结果

 103762376897069058/avatar?access_token=4f77072f0f7de259293f229c7a876130c79705d7': { "Accept-Language" = "en;q=1, fr;q=0.9, de;q=0.8, ja;q=0.7, nl;q=0.6, it;q=0.5"; "Content-Length" = 29120; "Content-Type" = "multipart/form-data; boundary=Boundary+0xAbCdEfGbOuNdArY"; "User-Agent" = "MixHR/0.0.1 (iPhone; iOS 7.0.4; Scale/2.00)"; } (null) 

那为什么身体没什么？ 我试过记录文件，它不是空的。

你试试这段代码：

 - (void)viewDidLoad { [super viewDidLoad]; NSString *strURL = @"http://YOUR_IP:YOUR_PORT/YOUR_PATH/.."; AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; AFJSONRequestSerializer *serializerRequest = [AFJSONRequestSerializer serializer]; [serializerRequest setValue:@"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; AFJSONResponseSerializer *serializerResponse = [AFJSONResponseSerializer serializer]; serializerResponse.readingOptions = NSJSONReadingAllowFragments; serializerResponse.acceptableContentTypes = [NSSet setWithObject:@"application/json"]; manager.requestSerializer = serializerRequest; manager.responseSerializer = serializerResponse; UIImage *image = [UIImage imageNamed:@"image.png"]; NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)]; NSDictionary *parameters = @{@"name":@"xxxx", @"surname":@"xxxx", }; [manager POST:strURL parameters:parameters constructingBodyWithBlock:^(id formData) { [formData appendPartWithFormData:imageData name:@"photo"]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@""%@,operation.responseString); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@""%@,operation.responseString); }]; }
