Android文件上傳使用HTTP PUT

Question

我有一個Web服務，它需要我發送文件數據到HTTP URL與PUT請求。我知道如何做，但在Android我不知道。

API文檔提供了示例請求。

PUT /images/upload/image_title HTTP/1.1 
Host: some.domain.com 
Date: Thu, 17 Jul 2008 14:56:34 GMT 
X-SE-Client: test-account 
X-SE-Accept: xml 
X-SE-Auth: 90a6d325e982f764f86a7e248edf6a660d4ee833 

bytes data goes here 

我寫了一些代碼，但它給了我錯誤。

HttpClient httpclient = new DefaultHttpClient(); 
HttpPut request = new HttpPut(Host + "images/upload/" + Name + "/"); 
request.addHeader("Date", now); 
request.addHeader("X-SE-Client", X_SE_Client); 
request.addHeader("X-SE-Accept", X_SE_Accept); 
request.addHeader("X-SE-Auth", Token); 
request.addHeader("X-SE-User", X_SE_User); 

// I feel here is something wrong 
File f = new File(Path); 
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE); 
entity.addPart("photo", new FileBody(f)); 
request.setEntity(entity); 

HttpResponse response = httpclient.execute(request); 

HttpEntity resEntityGet = response.getEntity(); 

String res = EntityUtils.toString(resEntityGet); 

我在做什麼錯？

Answer 1

嘗試類似的東西

try { 
URL url = new URL(Host + "images/upload/" + Name + "/"); 
HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
conn.setDoOutput(true); 
conn.setRequestMethod("PUT"); 
    // etc. 

    } catch (Exception e) { //handle the exception !} 

編輯 - 另一個更好的選擇：

使用內置HttpPut建議 - 實例看http://massapi.com/class/org/apache/http/client/methods/HttpPut.java.html

EDIT 2 - 的要求每條評論：

使用setEntity方法，例如new FileEntity(new File(Path), "binary/octet-stream");作爲參數，然後調用execute將文件添加到PUT請求。

Answer 2

下面的代碼工作正常，我：

URI uri = new URI(url); 
HttpClient httpclient = new DefaultHttpClient(); 
HttpPost post = new HttpPost(uri); 

File file = new File(filename);   

MultipartEntity entity = new MultipartEntity(); 
ContentBody body = new FileBody(file, "image/jpeg"); 
entity.addPart("userfile", body); 

post.setEntity(entity); 
HttpResponse response = httpclient.execute(post); 
HttpEntity resEntity = response.getEntity();
