Question

我正在尝试使用python原始套接字在URL上执行http帖子。但是我无法这样做，而http get请求正常工作。问题是当我尝试发帖时。

我的代码

import socket

HOST = 'www.example.com'

PORT = 80

DATA = "POST /example/email.php HTTP/1.1\r\n" # send headers
"HOST: example.com\r\n"
"Accept: */\r\n*"
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8\r\n"
"Referer: http://example.com/example/\r\n"
"action=subscribeme&email=laaarr@gmail.com\r\n"  #actual post payload data



def tcp_client():
    client = socket.socket( socket.AF_INET, socket.SOCK_STREAM)
    client.connect(( HOST, PORT ))
    client.send(DATA)
    response = client.recv(4096)
    print response

if __name__ == '__main__':
    tcp_client()

服务器端没有错误/回复（错误的请求或其他任何东西），但它似乎无法正常工作。其他一切都是正确的，因为我在POSTMAN和curl上检查了它们。

尝试

DATA = ("POST /example/email.php HTTP/1.1\r\n" # send headers
"HOST: example.com\r\n"
"Accept: *\r\n"
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8\r\n"
"Referer: http://example.com/example/\r\n"
"\r\n" # blank line seperating headers from body 
"action=subscribeme&email=laaarr@gmail.com\r\n")  #actual post payload data

你应该得到答案。

使用

import socket

HOST = 'www.example.com'

PORT = 80

DATA = ("POST /example/email.php HTTP/1.1\r\n" # send headers
"HOST: example.com\r\n"
"Accept: *\r\n"
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8\r\n"
"Referer: http://example.com/example/\r\n"
"\r\n" # blank line seperating headers from body 
"action=subscribeme&email=laaarr@gmail.com\r\n")  #actual post payload data 


def tcp_client():
    client = socket.socket( socket.AF_INET, socket.SOCK_STREAM)
    client.connect(( HOST, PORT ))
    client.send(DATA)
    response = client.recv(4096)
    print response

if __name__ == '__main__':
    tcp_client()

我得到了

HTTP/1.1 411 Length Required    
Content-Type: text/html    
Content-Length: 357    
Connection: close    
Date: Mon, 08 Aug 2016 11:23:16 GMT    
Server: ECSF (ewr/1443)

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

        <title>411 - Length Required</title>
    </head>
    <body>
        <h1>411 - Length Required</h1>
    </body>
</html>

这显然是一个错误但完全是一个回应。

用

DATA = ("POST /example/email.php HTTP/1.1\r\n" # send headers
"HOST: example.com\r\n"
"Accept: *\r\n"
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8\r\n"
"Content-Length: 41\r\n" #fixes error 411
"Referer: http://example.com/example/\r\n"
"\r\n" # blank line seperating headers from body 
"action=subscribeme&email=laaarr@gmail.com")  #actual post payload data

我得到正常的404 Not Found。

无法使用python raw套接字进行HTTP POST
