套接字错误#113没有通往主机的路由

Socket Error #113 No route to host

procedure TForm1.Button1Click(Sender: TObject);
var
  Intent: JIntent;
  datosPost: TIdMultiPartFormDataStream;
  mRespuestaPost: String;
begin
  try
    datosPost := TIdMultiPartFormDataStream.Create;
    datosPost.AddFormField('usuario', txtUser.Text);
    datosPost.AddFormField('password', txtPass.Text);
    mRespuestaPost := DataModule2.IdHTTP.Post

TIdHTTP组件是否需要另一个组件才能工作?

Does the TIdHTTP component require another component to work?

推荐答案

应用程序无法与x.x.x.x

要验证错误，请尝试使用Web浏览器或端口80上的Telnet从同一台计算机连接到主机x.x.x.x.如果无法正常连接Web，则Indy TIdHTTP也将无法连接. (Ping不适用于http)

To verify the error, try connecting to the host x.x.x.x from the same computer, using a web browser, or Telnet on port 80. If a normal web browser can not connect, Indy TIdHTTP will not be able too. (Ping is not useful for http)

注意:在Android上，使用内置的默认浏览器进行测试.另外，请检查应用程序权限是否包括INTERNET权限.

Note: on Android, use the built-in default browser to do the test. Also check that the app permissions include the permission INTERNET.
