Question

我从android调用php url来接收一些字符串值 我的Android代码如下：

       private static final String   BASE_URL="http://10.10.2.26/demo";
public static HttpResponse executeUrl(String action,String[] parameters) {


    try {
        HttpClient client = new DefaultHttpClient();



        URI website = new URI(BASE_URL+"/"+action);


        System.out.println("serverurl="+website);
        HttpGet request = new HttpGet();


        request.setURI(website);

        System.out.println("5");
        HttpResponse response = client.execute(request);


        System.out.println("no error in execute URL");
        return response;
    } catch (Exception e) {         

        System.out.println("In error of execute URL"+e.getLocalizedMessage());
    } 
    return null;
}

以下是我的PHP代码：

<?php

echo "kunal";
?>

执行后我收到null给android。

从php检索值的代码。它工作正常。

private void get_valueFromPhp(String php) {
    String responseString = null;

    try{    
        HttpClient httpclient = new DefaultHttpClient();
        String url ="your url"; 
        HttpPost httppost = new HttpPost(url);
        HttpResponse response = httpclient.execute(httppost);

        ByteArrayOutputStream out = new ByteArrayOutputStream();
        response.getEntity().writeTo(out);
        out.close();
        responseString = out.toString();
        Toast.makeText(getApplicationContext(),responseString,1000).show();
    } catch(Exception e) {
    }
}

php返回null http响应android
