在Android Studio中打开URL而不打开浏览器 [英] Hit a URL without opening browser in Android Studio

问题描述

我看过很多地方，尝试了很多东西，但似乎没有任何办法对我有用。任何人都可以在这里帮助我。我有一个想要在不打开手机浏览器的情况下点击的简单网址。我单击一个按钮，该URL需要被点击，而没有打开浏览器。我不关心该页面上的内容，我只想加载它。对于我的arduino暨以太网屏蔽物联网项目，我基本上需要它，其中我用自己的android手机控制设备。

i have looked at many places, tried a ton of things but nothing to seem to work for me somehow. Can anyone please help me here. I have a simple url that i want to hit without opening the browser in mobile phones. I am clicking a button and that url needs to get hit, without the browser getting opened. I am not concerned with what is on that page i just want to load it. I basically need it for my arduino cum ethernet shield IOT project, wherein i am controlling my appliances with my android phone.

这里是我在做什么的一小段。该apk生成没有错误，但该URL并未以某种方式被点击。

Here is a snippet of what i am doing. The apk is generating without errors but the url is not getting hit somehow.

谢谢

public void led1on(View view){
      try {
        URL u = new URL("http://172.17.27.173/?2");
        HttpURLConnection http = (HttpURLConnection) u.openConnection();
        http.connect();
    }catch (Exception e){
        e.getMessage();
        e.printStackTrace();
    }
}

推荐答案

您可以将其称为网络服务，而对结果不执行任何操作。例如：

You can call it as a web service and do nothing with the results. For example:

AsyncHttpClient client = new AsyncHttpClient();
client.get("http://172.17.27.173/yourpage", params, new AsyncHttpResponseHandler() {
    @Override
    public void onSuccess(String response) { // 200 OK
        // Do nothing
    }
    @Override
    public void onFailure(int statusCode, Throwable error, String content) { // Response not 200
    {
        // Some troubleshooting, etc.
    }
});

为了了解如何使用以上代码，您可以在这里看一下如何在Android中使用代码：
http://loopj.com/android-async -http /

In order to see how to use the above code, you can take a look at here which has explained how to use the code for Android: http://loopj.com/android-async-http/

也可以使用其他一些库，例如Apache Http客户端：
https://hc.apache.org/

It is also possible to use some other library such as Apache Http client as well: https://hc.apache.org/

try {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        myContent = httpEntity.getContent();

    } catch ...
