基于 python 的 https 服务器在提供响应后关闭连接

Question

我在终端中创建了简单的服务器

#!/usr/bin/env python3
import sys, os, socket, ssl
import requests
import string
import time
from socketserver import ThreadingMixIn
from http.server import HTTPServer,BaseHTTPRequestHandler
from io import BytesIO
import json
import cgi

class ThreadingServer(ThreadingMixIn, HTTPServer):
    pass

class RequestHandler(BaseHTTPRequestHandler):
    def do_POST(self):
        content_length = int(self.headers['Content-Length'])
        body = self.rfile.read(content_length)
        #self.send_header('Content-type', 'Application/json')
        self.send_response(200)
        self.end_headers()
        response = BytesIO()
        self.allow_reuse_address = True
        self.wfile.write(b"""{"signingResponse": {"compactidentity": "..SdOwnT70ZZDAjgSmQVP-_0keB_pu4FjkBg5DZDyFf_V5k0EUAY0KCHr2g2a6wOSs-JhsehdYUnrYCfkYItzxLg;info=<http://52.23.250.93:8080/certs/shaken.crt>;alg=ES256;ppt=shaken\n", "TEST": "Nitish","identity": "eyJhbGciOiJFUzI1NiIsInBwdCI6InNoYWtlbiIsInR5cCI6InBhc3Nwb3J0IiwieDV1IjoiaHR0cDovLzUyLjIzLjI1MC45Mzo4MDgwL2NlcnRzL3NoYWtlbi5jcnQifQ.eyJhdHRlc3QiOiJBIiwiZGVzdCI6eyJ0biI6WyIxMjM1NTU1MTIxMiJdfSwiaWF0IjoxNDgzMjI4ODAwLCJvcmlnIjp7InRuIjoiMTIzNTU1NTEyMTIifSwib3JpZ2lkIjoiOGE4ZWM2MTgtYzZiOS0zMGFlLWI0MjctYWY0MTA0YjFjMDJjIn0.SdOwnT70ZZDAjgSmQVP-_0keB_pu4FjkBg5DZDyFf_V5k0EUAY0KCHr2g2a6wOSs-JhsehdYUnrYCfkYItzxLg;info=<http://52.23.250.93:8080/certs/shaken.crt>;alg=ES256;ppt=shaken\n", "requestid": "0"}} """)

httpd = ThreadingServer(('192.168.1.2', 8003), RequestHandler)
httpd.socket = ssl.wrap_socket(httpd.socket, keyfile='/home/nakumar/key.pem', certfile='/home/nakumar/certificate.pem', server_side=True)
httpd.serve_forever()

使用上面的代码我正在尝试模拟服务器现在当服务器收到来自客户端的请求时，它发回响应并关闭连接，如下所示

请求

> POST /stir/v1/signing HTTP/1.1
Host: 192.168.1.2:8003
Accept: application/json
Content-Type: application/json
Content-Length: 331

upload completely sent off: 331 out of 331 bytes
* HTTP 1.0, assume close after body
< HTTP/1.0 200 OK
< Server: BaseHTTP/0.6 Python/3.5.2
< Date: Tue, 09 Oct 2018 12:43:21 GMT
< 
* Closing connection 0

所以我们可以看到连接关闭是在服务响应后来自服务器的，

有没有办法在响应送达后不关闭连接。

Answer 1

Curl 正在关闭连接，因为响应正文中不存在内容长度添加相同的内容后它开始工作

> POST /stir/v1/signing HTTP/1.1
Host: [FD00:10:6B50:4510:0:0:0:53]:8101
Accept: application/json
Content-Type: application/json
Content-Length: 325

* upload completely sent off: 325 out of 325 bytes
< HTTP/1.1 200 OK
< Server: HTTP/1.1 Python/3.5.2
< Date: Thu, 18 Oct 2018 09:13:11 GMT
< Content-type: Application/json
< Content-length: 150
< 
* Connection #1 to host FD00:10:6B50:4510:0:0:0:53 left intact

基于 python 的 https 服务器在提供响应后关闭连接

https server python based is closing connection after serving the response
