我们如何在ASIHTTPRequest中发布视频和图像？ [英] How we Can post Video and Image in ASIHTTPRequest?

问题描述

$ p



















$ p> NSString * url = [NSString stringWithFormat：@http://example.com/add_videoxml.php];

networkQueue = [[ASINetworkQueue alloc] init];

[networkQueue cancelAllOperations];

[networkQueue setShowAccurateProgress：YES];

// [networkQueue setUploadProgressDelegate：progressBar];

[networkQueue setDelegate：self];

[networkQueue setRequestDidFinishSelector：@selector（requestFinished :)];

[networkQueue setRequestDidFailSelector：@selector（requestFailed :)];


request = [[ASIFormDataRequest alloc] initWithURL：[NSURL URLWithString：url]];

[request setPostValue：@284forKey：@id];

[request setPostValue：@showforKey：@show];

[request addRequestHeader：@Content-Type
value：@multipart / form-data; boundary = ---------------- ----------- 1842378953296356978857151853\" ];

NSData * imgData = UIImageJPEGRepresentation（userImage，0.9）;
if（imgData！= nil）{
[request setFile：imgData withFileName：@LoveatnightandContentType：@image / jpegforKey：@image];
}

// [请求addRequestHeader：@Content-Type
// value：@multipart / form-data; boundary = ------- -------------------- 1842378953296356978857151853\" ];


$ b if（videoData！= nil）{
[request setFile：videoData withFileName：@LoveishardandContentType：@image / jpegforKey：@ 上传文件];

} //错误出现在这一行


[request setTimeOutSeconds：500];

// NSLog（@％@，request）;

[networkQueue addOperation：request];

[networkQueue go];

由OP添加

  [请求setFile：videoData withFileName：@Loveishard
 andContentType：@video / quicktime
 forKey：@uploadfile]; 
  

我使用这个，因为我的视频合成器是mov，但是它又给出错误

Added by the OP

[request setFile:videoData withFileName:@"Loveishard" 
                         andContentType:@"video/quicktime" 
                                 forKey:@"uploadfile"]; 

i use this becuase my video formate is mov , but it again give error
