使用POST方法

@Override

     super.onCreate(savedInstanceState); 

     Intent in=getIntent(); 

     Uri uri=in.getData(); 

      // l.setText(uri.toString()); 
      String p=uri.getQueryParameter(OAuth.OAUTH_VERIFIER); 
      CreateFolderActivity.m_provider.setOAuth10a(true);

       CreateFolderActivity.m_provider.retrieveAccessToken(p);

         Log.i("HelloWorld",hc.getResponseMessage()+" "+hc.getResponseCode());

       } 


    } 
    }`

你好我想在這裏使用POST方法上面的代碼發送一個JSON對象發送JSON對象，但我得到的內部服務器錯誤500.i讀取它出現的時候你寄一些意想不到的data.Actually其一個OAuth實現，我必須在用戶添加一個文件夾account.and我檢索訪問令牌successfully.please所說的其實是錯誤的代碼使用POST方法

"folder = {'name' : 'Test creation folder'}"是無效的JSON。 JSON Strings必須用雙引號括起來（"）。我想你的意思是這樣的：
```
{ 
    "folder": { 
     "name": "Test creation folder" 
    } 
} 
```
1. Refer to the JSON specification。
2. Validate your JSON。
3. Pretty print your JSON。
正確的JSON MIME類型application/json。
請勿手動構建您的JSON。使用org.json包。首先看JSONObject和JSONArray。

例子：

hc.setRequestProperty("content-type","application/json; charset=utf-8"); 
OutputStreamWriter wr = new OutputStreamWriter(hc.getOutputStream()); 
JSONObject data = new JSONObject().put("folder", 
        new JSONObject().put("name", "test creation folder")); 
wr.write(data.toString());
