在afnetworking 3.0中使用body字典发送POST请求

Question

我想询问如何使用AFNetworking 3.0发送带有正文的POST请求。 任何帮助将不胜感激！

Answer 1

来自AFNetworking's GitHub：

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];

    //Set the request body here

} error:nil];

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

NSURLSessionUploadTask *uploadTask;
uploadTask = [manager
          uploadTaskWithStreamedRequest:request
          progress:^(NSProgress * _Nonnull uploadProgress) {
              // This is not called back on the main queue.
              // You are responsible for dispatching to the main queue for UI updates
              dispatch_async(dispatch_get_main_queue(), ^{
                  //Update the progress view
                  [progressView setProgress:uploadProgress.fractionCompleted];
              });
          }
          completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
              if (error) {
                  NSLog(@"Error: %@", error);
              } else {
                  NSLog(@"%@ %@", response, responseObject);
              }
          }];

[uploadTask resume];

修改

如果您想设置自定义请求正文，上述答案非常有用。

如果您只需要POST一组简单的参数，就可以这样做：

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager setResponseSerializer:[AFHTTPResponseSerializer serializer]];

[manager POST:@"http://exaple.com/path" parameters:@{@"param1" : @"foo", @"anotherParameter" : @"bar"} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

    //success block

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

    //failure block

}];
