android - http post content-length（json post）

Question

我需要爲用戶登錄創建發佈請求。我設置Content-Length頭，但是當我POST請求它給org.apache.http.client.HttpResponseException：必要的長度

我的代碼

 DefaultHttpClient httpclient = new DefaultHttpClient(); 

     JSONObject data = new JSONObject(); 
     data.put("UserName", username); 
     data.put("Password", password); 
     data.put("RememberMe", false); 

     HttpPost httpost = new HttpPost(LOGIN_PATH); 
     StringEntity se = new StringEntity(data.toString()); 
     httpost.setEntity(se); 

     httpost.setHeader("Accept", "application/json"); 
     httpost.setHeader("Content-Type", "application/json"); 
     httpost.setHeader("Content-Length",""+se.getContentLength()); 

     ResponseHandler responseHandler = new BasicResponseHandler(); 
     return httpclient.execute(httpost, responseHandler); 

當我設置Content-Length頭它給'內容長度標題已經存在'，並且當刪除內容長度標題時它給出'長度是必需的'

謝謝。

變化

httpost.setHeader("Content-Lenght",""+se.getContentLength()); 

到

httpost.setHeader("Content-Length",""+se.getContentLength()); 

，因爲目前你逝去的Content-Lenght（長度拼寫錯誤），而不是Content-Length作爲關鍵setHeader方法
