我们如何在 ASIHTTPRequest 中发布视频和图像？

Question

我想将一张图像发布到我的网络服务和一个视频，但问题是，当它转到视频部分时，它会给我过度错误

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:@"284" forKey:@"id"];

 [request setPostValue:@"show" forKey:@"show"];

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

 NSData *imgData=UIImageJPEGRepresentation(userImage, 0.9);
 if(imgData != nil){
  [request setFile:imgData withFileName:@"Loveatnight" andContentType:@"image/jpeg" forKey:@"image"];
 }

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



 if(videoData != nil){
  [request setFile:videoData withFileName:@"Loveishard" andContentType:@"image/jpeg" forKey:@"uploadfile"];

 }// error is come on that line 


 [request setTimeOutSeconds:500];

 //NSLog(@"%@",request);

 [networkQueue addOperation:request];

 [networkQueue go]; 

---

由OP添加，

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

我使用它是因为我的视频格式是mov ，但它再次出错

Answer 1

videoData 在哪里声明？我在您的代码中没有看到任何对它的引用。

另外，为什么要提供 image/jpeg 作为视频的内容类型？我认为你的意思一定是 video/mp4 （或者可能是 video/mpeg 或 video/quicktime，具体取决于你从哪里获取视频）。

Answer 2

首先，您没有正确设置内容类型。您应该使用适合您的视频文件的 contentType，而不是使用 andContentType:@"image/jpeg"。要查看多媒体文件的不同 MIME 类型，请查看：http://www.w3schools。 com/media/media_mimeref.asp。

并使用例如（如果您有 .avi 文件）：

if(videoData != nil){
    [request setFile:videoData withFileName:@"Loveishard" 
                             andContentType:@"video/x-msvideo" 
                                     forKey:@"uploadfile"];
}// error is come on that line 

第二：上传二进制数据或文件时，数据会自动以“multipart/form-data”格式发布，您的情况是什么，所以不必担心设置标题。
