从Android应用程序到PHP脚本发送POST数据

问题描述

我想一些POST数据从一个Android应用程序发送到PHP脚本。 PHP脚本应该怎么样子？这是我试过，但它不工作;

Android的code：

 类SendPostReqAsyncTask扩展的AsyncTask＆LT;弦乐，太虚，字符串＆GT; {
    @覆盖
    保护字符串doInBackground（字符串... PARAMS）{        //创建一个新的HttpClient和邮政头
        HttpClient的HttpClient的=新DefaultHttpClient（）;
        HttpPost httppost =新HttpPost（http://www.alex26.0fees.net/script.php）;        尝试{
            //添加数据
            清单＆LT;＆的NameValuePair GT; namevaluepairs中=新的ArrayList＆LT;＆的NameValuePair GT;（2）;
            nameValuePairs.add（新BasicNameValuePair（ID，12345））;
            nameValuePairs.add（新BasicNameValuePair（StringData是，AndDev是太酷了！））;
            httppost.setEntity（新UrlEn codedFormEntity（namevaluepairs中））;            //执行HTTP POST请求
            HTT presponse响应= httpclient.execute（httppost）;        }赶上（ClientProtocolException E）{
            // TODO自动生成catch块
        }赶上（IOException异常五）{
            // TODO自动生成catch块
        }
        返回null;
    }    @覆盖
    保护无效onPostExecute（字符串结果）{    }
}
 

PHP脚本：

 ＆LT; PHP
如果（使用isset（$ _ POST ['身份证']））
    回声$ _ POST ['身份证'];
如果（使用isset（$ _ POST ['StringData是']））
    回声$ _ POST ['StringData是'];
？＆GT;
 

解决方案

通过POST发送到PHP脚本中的任何 $ _ POST 数组结束。什么脚本会用它做是另外一个问题。简单的测试，写入的$ _ POST内容到一个名为myfile.txt的（注：每个请求将覆盖该文件的内容）文件：

 ＆LT; PHP    的file_put_contents（myfile.txt的的print_r（$ _ POST，真实））;？＆GT;
 

在你的脚本呼应是没有意义的 - 你是不是消耗服务器的响应，也不显示它怎么可能是工作

I'm trying to send some POST data to a PHP script from an android application. How should the PHP script look like? This is what I tried but it doesn't work;

Android code:

class SendPostReqAsyncTask extends AsyncTask<String, Void, String> {
    @Override
    protected String doInBackground(String... params) {

        // Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://www.alex26.0fees.net/script.php");

        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("id", "12345"));
            nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);

        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            // TODO Auto-generated catch block
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {

    }
}

PHP script:

<?php
if(isset($_POST['id']))
    echo $_POST['id'];
if(isset($_POST['stringdata']))
    echo $_POST['stringdata'];
?>

解决方案

Anything sent via POST to PHP script ends in $_POST array. What the script will do with it is another question. Simplest test, that writes content of $_POST to a file named "myfile.txt" (note each request would overwrite content of the file):

<?php

    file_put_contents("myfile.txt", print_r( $_POST, true ));

?>

echoing in your script is pointless - you are not consuming server response nor displaying it so how could it "work"?
