极简运行
python -m http.sever
或
# test.py
import http.server
import socketserver
PORT = 8000
Handler = http.server.SimpleHTTPRequestHandler
with socketserver.TCPServer(("", PORT), Handler) as httpd:
print("serving at port", PORT)
httpd.serve_forever()
CGI-Bin
-
做了以上的启动之后就得到了一个文件服务器。
-
我主要复制教你如何用几行Python代码编写出一个简易Web服务器的代码。在当前目录下创建C:\Users\admin\Desktop\http\cgi-bin文件夹，CGI-bin 是一个用于存放脚本的文件夹，这些脚本将与 Web 浏览器交互以提供网页或网站的功能。通用网关接口 (CGI) 是一种资源，用于在 Web 设计中使用脚本。当脚本从服务器发送到 Web 浏览器时，通常在 url 中引用 CGI-bin。，用于实现类似jsp的功能。
-
但是大多数的博客都比较推荐使用此模块搭建简单的测试项目。
启动服务
import os
from http.server import HTTPServer, CGIHTTPRequestHandler
webdir="C:\\Users\\admin\\Desktop\\http"
os.chdir(webdir)
HTTPServer(("127.0.0.1", 8080), CGIHTTPRequestHandler).serve_forever()
import pickle
import os
student_keys = ("name", "gender", "age", "score")
if os.path.exists("student.data"):
with open("student.data", "rb") as file:
student = pickle.load(file)
student = student or {}
else:
student = {}
if not student:
student = dict.fromkeys(student_keys, "")
header = "Content-Type: text/html\n"
content = """
<html>
<body>

import cgi
import pickle
student_keys = ("name", "gender", "age", "score")
if os.path.exists("student.data"):
with open("student.data", "rb") as file:
student = pickle.load(file)
student = student or {}
else:
student = {}
if not student:
student = dict.fromkeys(student_keys, "")
form = cgi.FieldStorage()
for key in student_keys:
if key in form and form[key].value:
student[key] = form[key].value
with open("student.data", "wb") as file:

header = "Content-Type: text/html\n"
content = """

if(count == 0) {
clearInterval(timer_id)

</html>
"""
你可能应该访问“localhost:81/cgi-bin/index.py”。因为“localhost:81/cgi-bin/”是一个目录，不是一个python script。
使用体验
- 当在文件服务器的模式下，可以直接访问并渲染html文件,但是当我使用以下代码时，浏览器提示
var myChart = echarts.init(document.getElementById('main'));无法找到echarts对象。
import os
import cgi
import pickle
# student_keys = ("name", "gender", "age", "score")
# if os.path.exists("student.data"):
# with open("student.data", "rb") as file:
# student = pickle.load(file)
# student = student or {}
# else:
# student = {}
#
# if not student:
# student = dict.fromkeys(student_keys, "")
form = cgi.FieldStorage()
# for key in student_keys:
# if key in form and form[key].value:
# student[key] = form[key].value
# with open("student.data", "wb") as file:
# pickle.dump(student, file)
