在使用Python的服务器上是否找到了用于测试给定页面的应用程序

先决条件: Python Urllib 模块

在本文中,我们将编写脚本以使用 GUI 应用程序测试是否在服务器上找到给定页面。我们需要安装 Urllib 模块来执行这个操作。在终端中键入此命令。

pip install urllib

方法:

  • 导入 urllib 模块。
  • 使用 urllib.request.urlopen() 读取 URL。
  • 检查读取 URL 是否给出任何异常。

执行:

Python3
# import module
from urllib.request import urlopen, URLError, HTTPError
 
# exception handling to
# catch URL error
try:
    html = urlopen("https://www.geeksforgeeks.org/")
 
except URLError as e:
    print("Server not found!")
 
except HTTPError as e:
    print("HTTP error")
 
else:
    print("Server found")


Python3
# import modules
from tkinter import *
from urllib.request import urlopen, URLError
 
# user defined function
def URL_check():
    try:
        html = urlopen(str(e1.get()))
    except URLError as e:
        res = "Server not found!"
    else:
        res = "Server found"
    result.set(res)
 
 
# object of tkinter
# and background set to light grey
master = Tk()
master.configure(bg='light grey')
 
# Variable Classes in tkinter
result = StringVar()
 
 
# Creating label for each information
 
# name using widget Label
Label(master, text="Enter URL : ", bg="light grey").grid(row=1, sticky=W)
Label(master, text="Status :", bg="light grey").grid(row=3, sticky=W)
 
# Creating lebel for class variable
 
# name using widget Entry
Label(master, text="", textvariable=result,
      bg="light grey").grid(row=3, column=1, sticky=W)
 
 
e1 = Entry(master, width=50)
e1.grid(row=1, column=1)
 
# creating a button using the widget
b = Button(master, text="Check", command=URL_check, bg="white")
b.grid(row=1, column=2, columnspan=2, rowspan=2, padx=5, pady=5,)
 
mainloop()


输出:

Server found

在带有Tkinter的服务器上是否找到了用于测试给定页面的应用程序此脚本将上述实现与 GUI 相结合。

    else:

    result.set(res)
 
 
# object of tkinter

master.configure(bg='light grey')
 
# Variable Classes in tkinter

# Creating label for each information

Label(master, text="Enter URL : ", bg="light grey").grid(row=1, sticky=W)
Label(master, text="Status :", bg="light grey").grid(row=3, sticky=W)
 
# Creating lebel for class variable
 
# name using widget Entry
Label(master, text="", textvariable=result,
      bg="light grey").grid(row=3, column=1, sticky=W)
 
 
e1 = Entry(master, width=50)
e1.grid(row=1, column=1)
 
# creating a button using the widget
b = Button(master, text="Check", command=URL_check, bg="white")
b.grid(row=1, column=2, columnspan=2, rowspan=2, padx=5, pady=5,)
 
mainloop()

输出:

检查另一个 URL。
