HttpPost，HttpClient目标服务器无法响应

Question

发布时，我无法使用HttpClient连接到我的服务器，它可以与get正常工作，并且可以与发布到其他服务器（例如google）的工作正常，有什么想法吗？

我没有使用android。

通过浏览器访问服务器时，服务器响应良好。

由于这可能是服务器配置问题，我没有对该服务器的完全访问权限，它是托管的网络服务器，但是我可以访问cpanel

private static String GetURL(String inUrl, String post) {
    String inputLine = "";
    try {
        if (!inUrl.contains("http")) {
            throw new Exception("Invalid URL");
        } else {
            DefaultHttpClient client = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(inUrl);
            httpPost.addHeader("Accept-Charset", "UTF-8");
            httpPost.addHeader("Content-Type", "application/x-www-form-urlencoded");

            //create post
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
            nameValuePairs.add(new BasicNameValuePair("req", post));
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            HttpResponse response = client.execute(httpPost);
            BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
            inputLine = in.readLine();
            in.close();

        }
    }catch (Exception ex) {
        inputLine = "" + Comms.ERROR_COULD_NOT_REACH_SERVER;
        Log.writeLog("Could Not Reach Server: \"" + inUrl + "\"");
        ex.printStackTrace();
    }

    return inputLine;
}
