Error:org.apache.http.conn.HttpHostConnectException: Connection to http://10.0.2.2:8080refused When Android consumes rest api in php, and I connect to the api
错误：org.apache.http.conn.HttpHostConnectException：连接被http://10.0.2.2:8080拒绝当Android使用php中的rest api，我连接到api
I use eclipse and my android phone via usb to run my app . My api rest is made in php and use xampp and it run on port 8080 http://localhost:8080. Xampp works with my other web application , but Android does not work.
我通过 USB 使用 eclipse 和我的 android 手机来运行我的应用程序。我的 api rest 是用 php 制作的，使用 xampp 并在端口 8080 上运行http://localhost:8080。Xampp 适用于我的其他 Web 应用程序，但 Android 不起作用。
?-Also, my phone and my computer are not connected to the same network. -rest api can work in this case without internet?
?-另外，我的手机和我的电脑没有连接到同一个网络。-rest api 可以在没有互联网的情况下工作吗？
My code in android is this :
我在 android 中的代码是这样的：
private class TareaWSInsertar extends AsyncTask<String,Integer,Boolean> {
//agregado user_id, user_fullname, user_email
private int user_id;
private String user_fullname;
private String user_email;
protected Boolean doInBackground(String... params) {
boolean resul = true;
HttpClient httpClient = new DefaultHttpClient();
HttpPost post = new HttpPost("http://10.0.2.2:8080/rest/login/");
post.setHeader("content-type", "application/json");
try
{
//Construimos el objeto cliente en formato JSON
JSONObject dato = new JSONObject();
dato.put("email", params[0]);
dato.put("pwd", params[1]);
StringEntity entity = new StringEntity(dato.toString());
post.setEntity(entity);
HttpResponse resp = httpClient.execute(post);
String respStr = EntityUtils.toString(resp.getEntity());
JSONObject respJSON = new JSONObject(respStr);
user_id = respJSON.getInt("user_id");
user_fullname = respJSON.getString(user_fullname);
user_email = respJSON.getString("user_email");
if(!respStr.equals("true"))
resul = false;
}
catch(Exception ex)
{
Log.e("ServicioRest","Error!", ex);
resul = false;
}
return resul;
}
protected void onPostExecute(Boolean result) {
if (result)
{
Toast.makeText(getApplicationContext(), "" + user_id+ "-" + user_fullname + "-" + user_email, Toast.LENGTH_LONG).show();
}
}
}
I have tried different way :
我尝试过不同的方式：
http://10.0.2.2:8080/rest/login
http://localhost:8080/rest/login
http:/127.0.0.1:8080/rest/login
Note: I read that http://10.0.2.2only works when the android emulator is used,
I use my phone connected via usb .
注意：我读到http://10.0.2.2只有在使用 android 模拟器时才有效，我使用通过 usb 连接的手机。
but nothing works , even <uses-permission android:name="android.permission.INTERNET"/>I added in my manifest .
但没有任何效果，即使<uses-permission android:name="android.permission.INTERNET"/>我在清单中添加了。
Sorry help me!!, PD: I do not speak English

First you have an error:
首先你有一个错误：
HttpPost post = new HttpPost ( " http:/127.0.0.1:8080/rest/login/ ");
should be:
应该：
HttpPost post = new HttpPost ( " http://127.0.0.1:8080/rest/login/ ");
Next if the phone is not connected to your coputer network it wont ever connect to your local server aka your computer.
接下来，如果手机未连接到您的计算机网络，它将永远不会连接到您的本地服务器，也就是您的计算机。
If you have a wifi connection at your home check the ip address of the computer which runs xampp and replace it with localhost. If there is no wifi connection and your computer if connected to your modem (without router) then just check your ip address hereand replace it with localhost.
如果您家中有 wifi 连接，请检查运行 xampp 的计算机的 IP 地址并将其替换为localhost. 如果没有wifi连接并且您的计算机连接到调制解调器（没有路由器），那么只需在此处检查您的IP地址并将其替换为localhost。

I managed to fix this problem by writing my IP address from cmd -> ipconfig in the url:
我设法通过在 url 中从 cmd -> ipconfig 写入我的 IP 地址来解决这个问题：
HttpPost post = new HttpPost("http://192.168.x.x/rest/login/");
HttpPost post = new HttpPost(" http://192.168.xx/rest/login/");
