Django 代码
day1
不含文件的初级版本
连抄带改
import socket
from threading import Thread
server = socket.socket()
server.bind(('127.0.0.1',8001))
server.listen()
def func(conn):
# 接受请求数据 # 自从用了这个之后 不接收就不渲染 发过去的网页了
client_msg = conn.recv(1024).decode('utf-8')
print(client_msg)
# 组合响应协议的消息格式,然后发送响应信息
conn.send('HTTP/1.1 200 ok
'.encode('utf-8'))
# 打开index.html文件,返回给前端
with open('01 web 不含文件.html','rb')as f:
data = f.read()
conn.send(data)
# 放在这 否则影响代码渲染 具体为什么？
conn.send('who are you '.encode('utf-8'))
# 防止资源占用 所以要断开 无保存连接
conn.close()
# for i in range(10):
while 1 :
# 接收连接 如果不在这里会执行100个 只接收了一个，只执行一个线程
# 在外面一次接收多次执行
conn, addr = server.accept()
# 有一次发送了源码 没渲染 错开了？ 上面有conn,这里也正常渲染了
# conn.send('HTTP/1.1 200 ok
'.encode('utf-8'))
#开启线程并发
t = Thread(target=func , args=(conn,))
t.start()
# for i in range(22222):
# conn.send(b'b')
# conn.close()
# server.close()
上传文件的代码
import socket
from threading import Thread
server = socket.socket()
server.bind(('127.0.0.1',8001))
server.listen()
def func(conn):
client_msg = conn.recv(1024).decode('utf-8')
will_send = client_msg.split('
')[0].split(' ')[1]
# print(client_msg)
print(will_send)
if will_send == '/':
conn.send(b'HTTP/1.1 200 ok
')
with open('01传文件的.html','rb')as f:
data = f.read()
conn.send(data)
conn.close()
elif will_send == '/index.css':
conn.send(b'HTTP/1.1 200 ok
')
with open('index.css', 'rb')as f:
data = f.read()
conn.send(data)
conn.close()
elif will_send == '/index.js':
conn.send(b'HTTP/1.1 200 ok
')
with open('index.js', 'rb')as f:
data = f.read()
conn.send(data)
conn.close()
elif will_send == '/1.jpg':
conn.send(b'HTTP/1.1 200 ok
')
with open('1.jpg', 'rb')as f:
data = f.read()
conn.send(data)
conn.close()
elif will_send == '/favicon.ico':
conn.send(b'HTTP/1.1 200 ok
')
with open('favicon.ico', 'rb')as f:
data = f.read()
conn.send(data)
conn.close()
while 1 :
conn,abb = server.accept()
T = Thread(target=func, args=(conn,))
T.start()
conn 接收在循环里，不在主进程里，实现多少次请求，多少次响应
依然记不住 server.send(b'HTTP/1.1 200 ok
')
解释
：client_msg.split('
')[1].split(' ')[0]
client_msg =
GET / HTTP/1.1
Host: 127.0.0.1:8001
Connection: keep-alive
Cache-Control: max-age=0
Upgrade-Insecure-Requests: 1.....
GET /index.css HTTP/1.1
Host: 127.0.0.1:8001
Connection: keep-alive
本以为会用正则，结果使用client_msg.split（‘/r/n’）[0] 取第一行 然后 .split(' ')[1] 根据空格把/ 这些切出来
/ 第一个是/ 所以当是 /的时候 ，把html文件读出来给他
/index.css
/index.js
/1.jpg
/favicon.ico
传文件的网页
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" href="index.css">
<link rel="icon" href="favicon.ico">
</head>
<body>
<h1> 欢迎来到20期 </h1>
<img src="1.jpg" alt="">
<script src="index.js"></script>
</body>
</html>
index.js
alert('ddd dd');
index.css
h1{
background-color: red;
color: #1f87ff;
}

index.html 文件
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>
{{ name }}
<!--jinja2 格式-->

<ul>
{% for hobby in hobbylist %}
<li>{{ hobby }}</li>

基于jinja2的网页传输

data = f.read()
template = Template(data) # 生成模板文件
print('template
',template)
# >> > template = Template('Hello {{ name }}!') 格式
# >> > template.render(name='John Doe') == u'Hello John Doe!' render 格式两种
ret = template.render({"name": "于谦", "hobbylist": ["烫头", "泡吧"]}) # 把数据填充到模板里面
print('ret
',ret,'>>>>>>>>>>>>>>>>>>>>end')
# print(ret)
print('我',ret.encode('utf-8').decode('utf-8'),'你')
print('喔喔',repr(ret),ret.encode('utf-8'))
print('我',repr(bytes(ret, encoding="utf8")),bytes(ret, encoding="utf8"))
# return [bytes(ret, encoding="utf8"), ]
# return [ ret.encode('utf-8')] 字符转换成字节的两种写法
return [ret.encode('utf-8') ]
# 定义一个url和函数的对应关系
URL_LIST = [
("/index/", index),
]
def run_server(environ, start_response): # 不和socketserver一样，两个参数
start_response('200 OK', [('Content-Type', 'text/html;charset=utf8'), ]) # 设置HTTP响应的状态码和头信息
url = environ['PATH_INFO'] # 取到用户输入的url
func = None # 将要执行的函数
for i in URL_LIST:
if i[0] == url:
func = i[1] # 去之前定义好的url列表里找url应该执行的函数
break
print('func
',func)
if func: # 如果能找到要执行的函数
return func() # 返回函数的执行结果
else:
return [bytes("404没有该页面", encoding="utf8"), ]
if __name__ == '__main__':
httpd = make_server('127.0.0.1',8000, run_server)
print("Serving HTTP on port 8000...")
httpd.serve_forever()
