执行CGI Python脚本后，如何自动返回主页？

Question

I have been playing around with a web server and calling a Python routine using the CGI module. 我一直在玩Web服务器，并使用CGI模块调用Python例程。 That was challenging but it works fine :) 那是具有挑战性的，但效果很好:)

My problem is after the Python script execution, I want to introduce a routine in my script to redirect again to my home page. 我的问题是执行Python脚本后，我想在脚本中引入一个例程以再次重定向到我的主页。

I have seen in this forum questions like this one and the answer in most cases is: use the command line print("Location:http://your_page") , but I have already trie it and does not work in my case. 我在这个论坛上看到过类似这样的问题，大多数情况下的答案是：使用命令行print("Location:http://your_page") ，但是我已经尝试过了，在我的情况下不起作用。

In the next paragraph I will try to explain my whole "mini project" and then I let you see my code. 在下一段中，我将尝试解释我的整个“迷你项目”，然后让您看一下我的代码。

    <h2>Click the Button to run - "LED On/Off program"</h2>
    <input class=button onClick="location.href='http://my_web_page.net/cgi-bin/TCPC$
  </body>

This is my resulting home page. 这是我的主页。 Home page 主页

import socket
import time
import cgitb
cgitb.enable()

print("Content-type: text/html\n\n")
print("<html>\n<body>")
print("<div style=\"with:100%; font-size: 40px; font-weight bold; text-align: c$
print("The LED was turned On and after 2 seconds was turned Off")
client=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ip="192.168.2.112"
port=1234
address=(ip,port)
client.connect(address)
data = 'led_on'
client.sendall(data.encode('utf-8'))
time.sleep(2)
data = 'led_off'
client.sendall(data.encode('utf-8'))
client.close()
print("Location: http://my_web_page.net/\n")
print("</div>\n</body>\n</html>")

As result my Python script executes the routine but does not redirect back to my home page. 结果，我的Python脚本执行了例程，但没有重定向回到我的主页。 You can see by yourself the result in the next image. 您可以在下一张图像中自己查看结果。 This web page stays forever. 该网页永远存在。

最终网页

If you want to print your own output and redirect, you'll need to emit a snippet of simple javascript in your response to do the redirect. 如果要打印自己的输出并重定向，则需要在响应中发出一个简单的javascript代码段来进行重定向。

If you don't need output from your CGI at all, you need to print the Location: header before you print the double \\n\\n that terminates the headers. 如果根本不需要CGI的输出，则需要先打印Location：标头，然后再打印终止标头的双\\ n \\ n。 You also need to add the "pseudo" header Status: to set a 301 or 302 response code. 您还需要添加“伪”标头Status：来设置301或302响应代码。
