视频未在 iOS 的服务器上上传

Question

我正在尝试在 PHP 服务器上上传视频，但它没有上传。我的图像上传代码工作正常，但是当我尝试上传视频时它向我发送空白响应。我无法理解我的问题代码。请帮我解决这个问题。我没有找到这个问题的任何答案。

- (void)uploadVideo
{
  NSData *imageData = videoData;
  NSLog(@"imageData = %@",videoData);

  NSString *urlString = @"MyURL";
  NSLog(@"url=== %@", urlString);

  NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];

  request = [[NSMutableURLRequest alloc] init];
  [request setURL:[NSURL URLWithString:urlString]];
  [request setHTTPMethod:@"POST"];

  NSString *boundary = @"---------------------------14737809831466499882746641449";
  NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
  [request addValue:contentType forHTTPHeaderField: @"Content-Type"];

  /*  body of the post */

  NSMutableData *body = [NSMutableData data];
  [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
  [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"any_media\"; filename=\"%@\"\r\n",filename]dataUsingEncoding:NSUTF8StringEncoding]];
  [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
  [body appendData:[NSData dataWithData:imageData]];
  [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

  [request setHTTPBody:body];

  NSURLResponse *response;
  NSError *error =nil;

  NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
  NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

  NSLog(@"result from webservice:::--> %@", returnString);


  NSDictionary *parsingResultLogin = [NSJSONSerialization JSONObjectWithData:returnData options:0 error:nil];
  NSLog(@"parsingResultLogin = %@",parsingResultLogin);
}

也将内容长度添加到请求中。

NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[body length]];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];

还要确保imageData != nil;
