python - 传递数据时python socket http库发布请求不起作用

问题描述

正如我的标题所说，我正在制作一个带有基本 get 和 post 请求的小型 http 库。我已经完成了获取请求，但是我的发布请求表现得很奇怪。每当我将数据传递给帖子时，它都没有得到响应。当我不通过 body 属性（最后一个）时，它似乎工作得很好。我没有尝试使用请求库，我正在尝试自己制作一个。

谁能看到我做错了什么？我觉得我错过了一个标题，但我不知道是哪个。

import socket
from urllib.parse import urlparse
import json

TCRLF = "\r\n\r\n"
CRLF = "\r\n"



def post(url, headers=None, data=""):

    connection = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    request = build_request("POST", url, headers, data)
    print("request: " + request)
    print("url:" + url)
    print("headers :" + str(headers))

    url = urlparse(url)

    connection.connect((url.hostname, url.port or 80))
    connection.sendall(request.encode("UTF-8"))
    response = connection.recv(4096).decode("UTF-8")
    print("response: " +  response)
    #
    # (response_header, response_body) = response.split(TCRLF)
    # response_body = json.loads(response_body)
    #
    # print(response_header)
    # print(response_body)

    return None

def build_request(req_type, url, headers=None, body=""):

    url = urlparse(url)

    hostname = url.hostname
    path = url.path or "/"
    query = url.query
    port = url.port or 80

    print("hostname" + hostname)
    print("path : " + path)
    print("query :" + query)
    print("port :" + str(port))
    print("body:" + str(body))

    uri = "{}?{}".format(path, query) if query else path

    formatted_headers = "".join(
        "{}:{}\r\n".format(k, v) for k, v in headers.items())


    print("formatted: "+ formatted_headers)

    requestGet = "GET " + uri + " HTTP/1.0" + CRLF + "Host:" + hostname + CRLF + formatted_headers + TCRLF

    ##TODO body failing when passing object
    requestPost = "POST " + uri + " HTTP/1.0" + CRLF + "Host: " + hostname + CRLF + "Content-Length: " + str(
        len(body)) + CRLF + formatted_headers + TCRLF + body + TCRLF

    print("Request" + requestPost)

    if req_type=="POST":
        return requestPost
    else:
        return requestGet


def main():
    post("http://httpbin.org/post", {"Content-Type": "application/json" }, "{'Assignment': 1}")

if __name__ == '__main__':
    main()

body = '{"name":"mandar"}'
length = len(body)
#request = "GET / HTTP/1.1\r\nHost:%s\r\nUser-Agent: Mandar\r\n\r\n" % serverHost
p = HttpParser()
request = "POST / HTTP/1.1\r\nHost:{0}\r\nUser-Agent:Mandar\r\nContent-Type: application/json\r\nContent-Length: {1}\r\n\r\n{2}\r\n".format(serverHost, length, body)
