python http模块快速搭建“简单”服务器笔记

极简运行

python -m http.sever
1

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()

    with open("student.data", "rb") as file:
        student = pickle.load(file)
    student = student or {}
else:
    student = {}

if not student:
    student = dict.fromkeys(student_keys, "")

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
