socket手动发送http包头

 

说明

GET的头部

"""GET %s HTTP/1.0\r\nHost: %s\r\n\r\n""" % ("/test.html?a=1&b=2","127.0.0.1:8000")

POST的头部及data

需要指定Content-Length和Content-Type

"""POST %s HTTP/1.1\r\nHost: %s\r\nContent-Length: 19\r\nContent-Type: application/x-www-form-urlencoded\r\n\r\na=1&b=2&c=3&d=4&e=5""" % ("/test.html","127.0.0.1:8000")

 

示例

def test(req):
    if req.method == "GET":
        print(req.GET)
        print(req.body)
        return render(req,"test.html")
    elif req.method == "POST":
        print(req.POST)
        print(req.body)
        return HttpResponse("...")
    else:
        print(req.POST)
        print(req.body)
        return HttpResponse("...")
server端（django部分）
# -*- coding:utf-8 -*-


import socket

client = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client.connect(("127.0.0.1",8000))



# GET
text = """GET %s HTTP/1.0\r\nHost: %s\r\n\r\n""" % ("/test.html?a=1&b=2","127.0.0.1:8000")
client.send(bytes(text,encoding="utf-8"))

res = client.recv(8192)
print(res)

server端：
Content-Type: application/x-www-form-urlencoded 结果如下：
<QueryDict: {'a': ['1'], 'b': ['2'], 'c': ['3'], 'd': ['4'], 'e': ['5']}>  # request.POST
b'a=1&b=2&c=3&d=4&e=5'  # request.body

Content-Type: application/json结果如下：
<QueryDict: {}>  # request.POST
b'a=1&b=2&c=3&d=4&e=5'  # request.body
