获取XML从PHP Web服务的URL采用了android [英] Get xml from a php webservice url using android

问题描述

我想读从服务URL中的XML，我写了code，我的网址是好的，从浏览器中看到的，

I want to read a xml from a service url, I wrote the code, my url is ok, seen from browser,

    public String getXML(){
    String line = null;
    try {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpGet httpPost = new HttpGet("http://localhost/simplewebservice/index.php?user=1");

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        line = EntityUtils.toString(httpEntity);
    } catch (Exception ex) {
        Log.d("Error reading xml", ex.toString());
    }
    return line;
}

但它给了我下面的错误 java.net.SocketException异常：权限被拒绝。 任何人都可以有这个更好的解决办法？

But it gives me the following error java.net.SocketException: Permission denied. Can anyone have a better solution for this?

亲切的问候，

Pritom。

推荐答案

我相信，你使用模拟器。

I am sure that your using emulator.

安卓模拟器是独立的虚拟机本身。如果我们提供本地主机/ 127.0.0.1 作为主机名，则仿真器将尝试在其环境中搜索URL。为了避免这个问题，我们需要提供本地计算机的ip地址。

Andriod emulator is separate virtual machine by itself. If we provide localhost/127.0.0.1 as a hostname, then emulator will try to search url within its environment. To avoid this problem, we need to provide the ipaddress of local machine.

请注意，机器名作为主机名也会给问题。

Pls note that machine name as a hostname will also give problem.

127.0.0.1 refers to localhost in the Emulator, not your machine.

Use 10.0.2.2 to connect to your host machine.
