Android HTTP POST无法识别正确的网址

标签： java android http post

很抱歉发布一个很可能已经得到解答的问题，但我一直在撕毁其他帖子和教程，但仍无法解决这个问题。

我已经编写了一个虚拟应用来练习从android发送帖子请求，但我似乎无法让它发挥作用。所有它应该做的是，在按钮单击时，发送一个帖子到httpbin.org/post，然后显示TextView中返回的内容。

以下是MainActivity的代码：

package com.getthisshit.app;



public class MainActivity extends ActionBarActivity {

TextView text;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    text = (TextView) findViewById(R.id.text);

}

public void Go(View view){
    connect doit = new connect(this);
    doit.execute();
}

private class connect extends AsyncTask<Void, Void, String>{

    private Context context;

    public connect(Context context){
        this.context = context;
    }

    @Override
    protected String doInBackground(Void... arg0){


        List<NameValuePair> userInfo = new ArrayList<NameValuePair>(2);
        String URL = "http://httpbin.org/post";
        String response = "no response";

        HttpClient httpClient = new DefaultHttpClient();
        HttpEntity httpEntity = null;
        HttpResponse httpResponse = null;
        HttpPost httpPost = new HttpPost(URL);

        userInfo.add(new BasicNameValuePair("email", "bad@man.com"));
        userInfo.add(new BasicNameValuePair("password", "SayWhatAgain"));

        try{
            httpPost.setEntity(new UrlEncodedFormEntity(userInfo));
            httpResponse = httpClient.execute(httpPost);
            httpEntity = httpResponse.getEntity();
            response = EntityUtils.toString(httpEntity);
        } catch (UnsupportedEncodingException e){
            e.printStackTrace();
        } catch (ClientProtocolException e){
            e.printStackTrace();
        } catch (IOException e) {
             e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        }

        return response;

    }

    @Override
    protected void onPostExecute(String response){
        //Toast.makeText(context , response, Toast.LENGTH_SHORT).show();
        text.setText(response);
    }
}

}

按下按钮时，这是logcat：

我认为这一行特别重要：

java.net.UnknownHostException：无法解析主机＆＃34; httpbin.org＆＃34;：没有与主机名关联的地址

但我的google-fu让我失望

当我将相同的帖子放入hurl.it时，我得到了正确的回复。 我在清单文件中有互联网权限 我正在使用Android 4.3测试我的HTC1上的应用程序 我在wifi上有互联网连接

提前致谢。如果我不明白这一点，我意识到这不是世界末日，但这会让我感到非常难过。

1 个答案:

答案 0 :(得分：0)

我尝试在本地托管的Web服务上执行HTTP POST时，昨天在Nexus 7上遇到了同样的错误。对我来说，当我重启设备时，错误就消失了。有点远，但它对我有用！
