vb.net 用户输入 url

Question

我目前正在制作一个 VB.net 控制台应用程序，它调用基于 Web 的 API 将结果返回到控制台。我想做的是让用户自己输入IP。

        Dim sURL As String
    sURL = "http://api.hackertarget.com/geoip/?q=1.1.1.1"

我希望能够用用户输入替换 1.1.1.1

谢谢

编辑：

当我运行程序时我需要在控制台中插入两次IP

  Dim nL As String = Environment.NewLine
    Console.Write("Please enter an IP Address: ")
    Dim input = Console.ReadLine()

这是我用来接受用户输入的代码

编辑2：完整代码

Imports System
Imports System.Net
Imports System.IO
Module Module1

Sub Main()
IP:
    Dim nL As String = Environment.NewLine
    Console.Write("Please enter an IP Address: ")
    'Console.WriteLine()
    Dim input = Console.ReadLine()
    Dim sURL As String
    sURL = "http://api.hackertarget.com/geoip/?q=1.1.1.1".Replace("1.1.1.1", Console.ReadLine())
    Dim wrGETURL As WebRequest
    wrGETURL = WebRequest.Create(sURL)
    Dim myProxy As New WebProxy("myproxy", 80)
    myProxy.BypassProxyOnLocal = True
    Dim objStream As Stream
    objStream = wrGETURL.GetResponse.GetResponseStream()
    Dim objReader As New StreamReader(objStream)
    Dim sLine As String = ""
    Dim i As Integer = 0
    Do While Not sLine Is Nothing
        i += 1
        sLine = objReader.ReadLine
        If Not sLine Is Nothing Then
            Console.WriteLine("{0}:{1}", i, sLine)
        End If
    Loop
    Console.ReadLine()
    GoTo IP
End Sub

你应该使用 -

Dim sURL As String
Console.Write("Please enter an IP Address: ")
sURL = "http://api.hackertarget.com/geoip/?q=1.1.1.1".Replace("1.1.1.1", Console.ReadLine())
