Question

我的应用程序适用于Facebook，并使用JSON参数发布请求。请求发送约7-8分钟然后我捕获一个SocketTimeOutException。在10分钟内，我可以再次发送请求。

以下是代码：

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;
}

为什么会这样？

如果params是JSON-String，则可能需要替换：

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

与

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

发送HttpPost请求时出现SocketTimeOutException
