Android - HTTP GET 请求

我开发了一种显然有效的 HTTP GET 方法。

public class GetMethodEx {


public String getInternetData() throws Exception{

        new TrustAllManager();
        new TrustAllSSLSocketFactory();

        BufferedReader in = null;
        String data = null;


        try
        {
            HttpClient client = new DefaultHttpClient();
            URI website = new URI("https://server.com:8443/Timesheets/ping");
            HttpGet request = new HttpGet();
            request.setURI(website);
            HttpResponse response = client.execute(request);
            response.getStatusLine().getStatusCode();

            in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
            StringBuffer sb = new StringBuffer("");
            String l = "";
            String nl = System.getProperty("line.separator");
            while ((l = in.readLine()) !=null){
                sb.append(l + nl);
            }
            in.close();
            data = sb.toString();
            return data;        
        } finally{
            if (in != null){
                try{
                    in.close();
                    return data;
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
        }
}

这是我的模拟器从 www.google.com 检索响应时的打印屏幕

GOOGLE.COM 运行的屏幕截图

下面的代码是我的检索方法，将其显示在屏幕上。

public class Home extends Activity {

TextView httpStuff;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.httpexample);
    httpStuff = (TextView) findViewById(R.id.tvhttp);
   new LongOperation().execute("");

}

private class LongOperation extends AsyncTask<String, Void, String> {
  @Override

  protected String doInBackground(String... params) {

      GetMethodEx test = new GetMethodEx();      
      String returned = null;

    try {
        returned = test.getInternetData();

    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
        return returned;
  }      

  @Override
  protected void onPostExecute(String result) {    
     httpStuff.setText(result);       
  }

但是，当我用自己的服务器尝试时。

"https://服务器:端口/xwtimesheets/ping"

我有以下屏幕

我的服务器不工作

这是 GetMethodEx 类的编辑版本。 MySSLSocketFactory 允许您连接任何服务器而无需检查其证书。如您所知，这并不安全。我建议您将服务器的证书添加为受设备信任。

顺便说一句，您的服务器证书有效期已过期。即使您将其添加为受信任，您也可能无法连接到您的服务器。

        HttpGet request = new HttpGet();
        request.setURI(website);
        HttpResponse response = client.execute(request);
        response.getStatusLine().getStatusCode();

        in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuffer sb = new StringBuffer("");
        String l = "";
        String nl = System.getProperty("line.separator");
        while ((l = in.readLine()) != null) {
