java - Android ECONNREFUSED(连接被拒绝)

Question

我已尝试使用此代码从我的 android 应用程序向服务器发送数据。

try {
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost("http://myip/adminlogin.php");
    httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    HttpResponse response = httpClient.execute(httpPost);

    HttpEntity entity = response.getEntity();

    is = entity.getContent();

    BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"), 8);
    StringBuilder sb = new StringBuilder();

    String line = null;
    while ((line = reader.readLine()) != null)
    {
        sb.append(line + "\n");
    }
    result = sb.toString();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
return result;

尝试使用用户名和密码对登录时出现以下错误消息。

[socket][0] connection /myip:80;LocalPort=33049(0) close [socket][/0.0.0.0:33049] W/System.err: org.apache.http.conn.HttpHostConnectException: Connection to http://myip refused Caused by: java.net.ConnectException: failed to connect to /myip (port 80) after 90000ms: isConnected failed: ECONNREFUSED (Connection refused)

myip 可以通过网络浏览器访问，所以我认为端口 80 是可以的。文件路径也OK。我检查了数据库，它运行正常。我在 list 文件中设置了必要的权限。

你的手机和你用ip号连接的电脑在同一个网络吗？服务器在公共(public)互联网上吗？当我忘记将手机连接到本地 wifi 网络并且它想要连接到本地网络上的服务器时，我收到此错误。
