Question

我正在使用异步任务来登录用户，虽然php登录页面是我的java android代码：

 protected String doInBackground(String... urls) {
    String result = "";

    for(int i = 0; i <= 0; ++i) {
        result = this.invokePost(urls[i], this.postData);
    }

    return result;
}

private String invokePost(String requestURL, HashMap<String, String> postDataParams) {
    String response = "";

    try {
        URL url = new URL(requestURL);
        HttpURLConnection e = (HttpURLConnection)url.openConnection();
      /*  e.setReadTimeout(15000);
        e.setConnectTimeout(15000);*/
        e.setRequestMethod("POST");
        e.setDoInput(true);
        e.setDoOutput(true);
        OutputStream os = e.getOutputStream();
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
        writer.write(this.getPostDataString(postDataParams));
        writer.flush();
        writer.close();
        os.close();
        int responseCode = e.getResponseCode();
        String line;
        if(responseCode == 200) {
            for(BufferedReader br = new BufferedReader(new InputStreamReader(e.getInputStream())); (line = br.readLine()) != null; response = response + line) {
                ;
            }
        } else {
            response = "";
            Log.d("responce code", responseCode + "");
        }
    } catch (Exception ex) {
        response ="An exception has occured" + ex.getMessage();
        ex.printStackTrace();
        Log.d("exception",ex.toString());
    }

    return response;
}

Login.java：

 HashMap PostData = new HashMap();
        PostData.put("username", username);
        PostData.put("password", username);
        BackgroundWorker LoginWorker= new BackgroundWorker(this,PostData);
        LoginWorker.execute("http://192.168.43.22:8080/login.php");

我没有使用模拟器，虽然我通过我的nexus 5手机运行应用程序，我的手机和我的电脑都连接到路由器wifi

但是我得到一个连接异常（我无法通过我的nexus 5 ping我的电脑）

如何在手机和电脑之间打开连接

Answer 1

使用cmd中的ipconfig获取您的电脑，并在没有端口的情况下使用它

LoginWorker.execute("http://192.168.**.**/login.php");

如果不在防火墙中打开端口80

通过Android手机连接到pc localhost而不使用模拟器
