我正在运行Python3,在本地主机上运行Django,并监听http://127.0.0.1:8000/
我想通过不同的方式来测试它,比如request
和socket
import requests
res = requests.request("GET", "http://127.0.0.1:8000/")
txt = res.content
print(res)
res.close()
# <Response [200]>
它运行良好,而且
在我运行的Django控制台上,它显示了[07/Jul/2018 16:04:26] "GET / HTTP/1.1" 200 6744
现在改为使用requests
连接到socket
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 8000))
msg = b'GET / HTTP/1.1'
s.send(msg)
print(s)
s.close()
# <socket.socket fd=1324, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('127.0.0.1', 55312), raddr=('127.0.0.1', 8000)>
我的程序中没有显示错误
但是在我运行的Django控制台上,我得到了以下异常
Invalid HTTP_HOST header: 'tony.jhou-1.xxservice.com:8000'. You may need to add 'tony.jhou-1.xxservice.com:8000' to ALLOWED_HOSTS.

我是socket编程的新手,刚刚开始学习网络,我想也许我应该发送更多的请求头。请告诉我怎么做,谢谢。
发布于 2018-07-08 06:45:53
是的,您需要发送更多数据。一个最小的HTTP1.1请求需要第二行,其中包含一个Host
标头,指定应该处理请求的主机的名称或地址,并且请求标头行后面必须跟一个空行,以告诉服务器标头已经完全收到。
在HTTP中,行尾由一对字符、一个回车符和一个换行符表示。在Python字符串中,\r
表示回车符,\n
表示换行符。(换行符有时称为换行符,因此称为\n
代码。)这意味着您必须编写\r\n
来标记请求中每一行的结束。
所以,你需要的是:
msg = b'GET / HTTP/1.1\r\nHost: 127.0.0.1\r\n\r\n'
最后的\r\n
生成指示标头结束的空行。
在您进行更改之后,您的服务器可能会报告一个不同的错误,因为您的客户端程序会立即关闭其套接字。这会中断客户端和服务器之间的连接。当服务器试图发送它的响应时,它会发现连接已经断开,它可能会对此报错。要避免这种情况,请将客户端更改为使用s.recv
,以便在执行s.send()
之后等待并读取来自服务器的响应。类似于:
while True:
resp = s.recv(8000)
if resp:
print resp
else:
break
