php - Android 和 PHP 创建 API

Question

我正在尝试为我的 Android 应用程序设置一个 PHP API 以与之交互，我的问题是发布数据似乎永远不会发布，而且我永远无法从给定的 URL 检索响应正文(HTML/TXT) .

我的代码

Thread thread = new Thread(new Runnable(){
        @Override
        public void run() {
            try {
                HttpClient client = new DefaultHttpClient();
                HttpPost clientpost = new HttpPost("http://192.168.1.129/updateMain.php");

                try {
                    List<NameValuePair> params = new ArrayList<NameValuePair>(2);

                    params.add(new BasicNameValuePair("_id", "1"));
                    params.add(new BasicNameValuePair("job_name", "Test"));

                    clientpost.setEntity(new UrlEncodedFormEntity(params));

                    HttpResponse response = client.execute(clientpost);

                    String responseBody = EntityUtils.toString(response.getEntity());

                } catch(Exception e)
                {
                    Log.e("Error", e.toString());
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });

    thread.start();

如果我可以发布数据，那么我就可以将 JSON 发布到服务器并从服务器检索 JSON，从而克服我目前面临的最大障碍。

非常感谢任何帮助。

public String getResponse(String url, List<NameValuePair> nameValuePairs) {

    url = url.replaceAll(" ", "%20");
    String result = "ERROR";
    Log.d("Pair", nameValuePairs.toString());
    HttpClient httpclient = new DefaultHttpClient();
    HttpParams http_params = httpclient.getParams();
    http_params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION,
            HttpVersion.HTTP_1_1);
    HttpConnectionParams.setConnectionTimeout(http_params, TIMEOUT);
    HttpConnectionParams.setSoTimeout(http_params, TIMEOUT);
    HttpResponse response = null;

    try {
        HttpPost httppost = new HttpPost(url);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        response = httpclient.execute(httppost);
    } catch (ClientProtocolException e) {
        e.printStackTrace();
        result = "ERROR";
    } catch (IOException e) {
        e.printStackTrace();
        result = "ERROR";
    }

    try {
        // Get hold of the response entity
        HttpEntity entity = null;
        if (response != null) {
            entity = response.getEntity();
        }
        if (entity != null) {
            InputStream inputStream = entity.getContent();
            result = convertStreamToString(inputStream);
        }

    } catch (IOException e) {
        result = "ERROR";
    }

    httpclient.getConnectionManager().shutdown();
    return result;
}

将此方法与 AsyncTask 或后台线程一起使用
