發送HttpPost請求時發生SocketTimeOutException

我的應用程序與Facebook協同工作，並使用JSON參數發佈請求。請求被髮送〜7-8分鐘，然後我發現一個SocketTimeOutException。 10分鐘後，我可以再次發送請求。發送HttpPost請求時發生SocketTimeOutException

下面的代碼：

public static String httpTPRequest(String url, String params) { 
    String response = Static.EMPTY; 
    HttpPost httpPost = new HttpPost(url); 
    httpPost.addHeader("Content-Type", "application/json"); 
    HttpParams httpParams = new BasicHttpParams(); 
    DefaultHttpClient httpClient = new DefaultHttpClient(httpParams); 
    HttpConnectionParams.setConnectionTimeout(httpParams, HTTP_TIMEOUT); 
    HttpConnectionParams.setSoTimeout(httpParams, HTTP_TIMEOUT); 

    try { 
     httpPost.setEntity(new StringEntity(params, "UTF-8")); 
     HttpResponse httpResponse = httpClient.execute(httpPost); 
     HttpEntity entity = httpResponse.getEntity(); 
     if (entity != null) { 
      response = EntityUtils.toString(entity); 
     } 
    } catch (Exception e) { 
     Debug.log(TAG, "tp server request:" + e.getMessage()); 
    } 

    return response; 
}

爲什麼會發生？

請加上SocketTimeOutException –

什麼的堆棧跟蹤你的網址是？ params是什麼樣的？也許Facebook沒有回答。你可以嘗試用curl手動創建相同的請求嗎？ –

我不僅使用此代碼的Facebook。我的網址是http://api.verumnets.ru/?v=1，params是{「data」：「limit」：40}，「service」：「feedInbox」} –

-1

如果params爲一個JSON字符串，你可能需要更換：

httpPost.setEntity(new StringEntity(params,"UTF-8"));

與

httpPost.setEntity(new ByteArrayEntity(params.getBytes("UTF8")));
