如何使用如下的ASIHttpRequest創建請求？

我是沃金在YouTube上上傳可恢復： https://developers.google.com/youtube/2.0/developers_guide_protocol_resumable_uploads#Sending_a_Resumable_Upload_API_Request 如何使用如下的ASIHttpRequest創建請求？

我沒有創建像下面用ASIHttpRequest的請求。如何使它工作？謝謝！任何幫助將不勝感激！

（1）

POST /resumable/feeds/api/users/default/uploads HTTP/1.1 
Host: uploads.gdata.youtube.com 
Authorization: Bearer ACCESS_TOKEN 
GData-Version: 2 
X-GData-Key: key=adf15ee97731bca89da876c...a8dc 
Content-Length: 0 
Slug: my_file.mp4

（2）

POST /resumable/feeds/api/users/default/uploads HTTP/1.1 

Host: uploads.gdata.youtube.com 

Authorization: Bearer ACCESS_TOKEN 
GData-Version: 2 
X-GData-Key: key=adf15ee97731bca89da876c...a8dc 
Content-Length: 1941255 
Slug: my_file.mp4 
Content-Type: application/atom+xml; charset=UTF-8 

<?xml version="1.0"?> 
<entry xmlns="http://www.w3.org/2005/Atom" 
    xmlns:media="http://search.yahoo.com/mrss/" 
    xmlns:yt="http://gdata.youtube.com/schemas/2007"> 
    <media:group> 
    <media:title type="plain">Bad Wedding Toast</media:title> 
    <media:description type="plain"> 
     I gave a bad toast at my friend's wedding. 
    </media:description> 
    <media:category 
     scheme="http://gdata.youtube.com/schemas/2007/categories.cat">People 
    </media:category> 
    <media:keywords>toast, wedding</media:keywords> 
    </media:group> 
</entry>

這是我的（2），請求完成沒有錯誤，但該responseData是empty.I代碼不知道爲什麼！

NSURL *uploadUrl = [NSURL URLWithString:[NSString stringWithFormat:@"http://uploads.gdata.youtube.com/resumable/feeds/api/users/default/uploads"]]; 
    ASIFormDataRequest *theRequest = [ASIFormDataRequest requestWithURL:uploadUrl]; 

    NSString *xmlStr = [NSString stringWithFormat:@"<?xml version=\"1.0\"?>\n" 
         @"<entry xmlns=\"http://www.w3.org/2005/Atom\"\n" 
         @"xmlns:media=\"http://search.yahoo.com/mrss/\"\n" 
         @"xmlns:yt=\"http://gdata.youtube.com/schemas/2007\">\n" 
         @"<media:group>\n" 

         //Title 
         @"<media:title type=\"plain\">%@</media:title>\n" 
         //Description 
         @"<media:description type=\"plain\">\n" 
         @"%@\n" 
         @"</media:description>\n" 
         //Category 
         @"<media:category\n" 
         @"scheme=\"http://gdata.youtube.com/schemas/2007/categories.cat\">Entertainment\n" 
         @"</media:category>\n" 
         //Keywords 
         @"<media:keywords>Camera,PowerCam</media:keywords>\n" 

         @"</media:group>\n" 
         @"</entry>\n",  @"PowerCam.mov",@"description" ]; 


    [theRequest setTimeOutSeconds:60]; 
    [theRequest addRequestHeader:@"Authorization" value:[NSString stringWithFormat:@"Bearer %@",_oauth.accessToken]]; 
    [theRequest addRequestHeader:@"GData-Version" value:@"2"]; 
    [theRequest addRequestHeader:@"X-GData-Key"  value:[NSString stringWithFormat:@"key=%@", YouTuDevkey]]; 
    [theRequest addRequestHeader:@"Content-Length" value:[NSString stringWithFormat:@"%d",xmlStr.length]]; 
    [theRequest addRequestHeader:@"Slug"   value:@"PowerCam.mov"]; 
    [theRequest addRequestHeader:@"Content-Type" value:@"application/atom+xml; charset=UTF-8"]; 

    [theRequest appendPostData:[xmlStr dataUsingEncoding:NSUTF8StringEncoding]]; 
    [theRequest setUploadProgressDelegate:self]; 
    theRequest.delegate = self; 
    theRequest.tag = eWSKYouTubeSharerUploadingVideoMetadata; 
    self.requestTag = eWSKYouTubeSharerUploadingVideoMetadata; 
    self.request = theRequest; 
    [[ASIManager manager] addRequest:theRequest]; 
    [[ASIManager manager] startQueue];

它究竟是如何工作的？你可以發佈你的'ASIHTTPRequest'代碼嗎？ – 2012-10-16 11:26:14

問題解決了！代碼工作正常。 API響應位於標題中，因此responseData爲空:) – Patrick

良好的工作:-)不要忘記在下面發佈您的答案，然後您可以接受它。 – 2012-10-17 08:27:41

下面的例子顯示了一個示例API響應於請求上傳視頻元數據爲一個可恢復上傳：

HTTP/1.1 200 OK 
Location: http://uploads.gdata.youtube.com/resumableupload/AF8GKF...0Glpk0Aw 
Date: Fri, 04 Dec 2009 16:14:30 GMT 
Pragma: no-cache 
Expires: Fri, 01 Jan 1990 00:00:00 GMT 
Cache-Control: no-cache, no-store, must-revalidate 
Content-Length: 0 
Content-Type: text/html

代碼工作正常。「位置」網址位於標題中，而不是正文中，因此responseData爲空:)

有關如何使用它的信息，請參閱the ASIHTTPRequest how-to。粗略地說，你會有這樣的事情：

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; 
[request addRequestHeader:@"X-GData-Key" value:@"adf15ee97731bca89da876c...a8dc9"]; 
// add the other special headers as well 
NSString *xmlBody = // create the XML data in the body 
[request appendPostData:[xmlBody dataUsingEncoding:NSUTF8StringEncoding]]; 
[request startSynchronous];

假設你想要從後臺線程做同步請求。
