Question

我使用post方法将视频上传到服务器。但是有问题是服务器没有收到它。

下面是我发布视频的代码。

这段代码在上传图片方面对我有用，但是当视频出现失败时

我使用UIImagePickerController来获取视频

AVAssetExportSession转换为mp4

当我尝试上传我的视频时，服务器看不到我的帖子。

但我无法弄明白为什么？

请给我一些建议。感谢。

Try this
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"%@%@",BASEURL,url] parameters:parameter constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            if (videoData) {
                [formData appendPartWithFileData: videoData name:@"video_file" fileName:@"video_file.mp4" mimeType:@"video/mp4"];

              // you file to upload
            }
        }error:nil];

        AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
        manager.responseSerializer = [AFJSONResponseSerializer serializer];

        NSURLSessionUploadTask *uploadTask;
        uploadTask = [manager
                      uploadTaskWithStreamedRequest:request
                      progress:^(NSProgress * _Nonnull uploadProgress) {
                          dispatch_async(dispatch_get_main_queue(), ^{
                          });
                      }
                      completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                          if (error) {
                              NSLog(@"Error: %@", [[NSString alloc]initWithData:[[error valueForKey:@"userInfo"] valueForKey:@"com.alamofire.serialization.response.error.data"] encoding:NSUTF8StringEncoding]);

                          } else {
                          }

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
        manager.requestSerializer = [AFJSONRequestSerializer serializer];

      AFHTTPRequestOperation *operation = [manager POST:apiType parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){
          [formData appendPartWithFileData:fileData name:@"file" fileName:strFileName mimeType:mimeType];

        }success:^(AFHTTPRequestOperation *operation,id responseObject){

            NSLog(@"JSON: %@", responseObject);
            successHandler(operation, responseObject);
        }
              failure:^(AFHTTPRequestOperation *operation, NSError *error){
                  myProgressView.progress = 1.0;

              }];
        }];
