python中本地主机上的HTTP删除请求

问题描述

我正在尝试在本地主机上构建客户端和服务器，并使用 python 中的请求模块实现获取、发布和删除 http 请求。我有这个用于服务器：

from http.server import HTTPServer,BaseHTTPRequestHandler
from urllib.parse import parse_qs

names_dict = {'john': 'smith','david': 'jones','michael': 'johnson','chris': 'lee'}


class RequestHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        self.log_message("Incoming GET request...")
        try:
            name = parse_qs(self.path[2:])['name'][0]
        except:
            self.send_response_to_client(404,'Incorrect parameters provided')
            self.log_message("Incorrect parameters provided")
            return

    if name in names_dict.keys():
        self.send_response_to_client(200,names_dict[name])
    else:
        self.send_response_to_client(404,'Name not found')
        self.log_message("Name not found")

def do_POST(self):
    self.log_message('Incoming POST request...')
    data = parse_qs(self.path[2:])
    try:
        names_dict[data['name'][0]] = data['last_name'][0]
        self.send_response_to_client(200,names_dict)
    except KeyError:
        self.send_response_to_client(404,'Incorrect parameters provided')
        self.log_message("Incorrect parameters provided")

def send_response_to_client(self,status_code,data):
    # Send OK status
    self.send_response(status_code)
    # Send headers
    self.send_header('Content-type','text/plain')
    self.end_headers()

    # Send the response
    self.wfile.write(str(data).encode())

server_address = ('127.0.0.1',8080)
http_server = HTTPServer(server_address,RequestHandler)
http_server.serve_forever()

这是给客户的：

import requests

r = requests.get("http://127.0.0.1:8080/",params={"name":'michael'})
print("Request method: GET,\
    Response status_code: {},Response data: {}".format(r.status_code,r.text))
r = requests.post("http://127.0.0.1:8080/",params = {'name':'peter','last_name':'peterson'})
print("Request method: POST,r.text))
r = requests.delete("http://127.0.0.1:8080/",params={'name':'chris','last_name':'lee'})
print("Request method: DELETE,r.text))

如何在服务器文件中添加代码以根据名称和姓氏从字典中删除条目，然后在发布请求后在屏幕上打印新字典。

解决方法

我不知道是纯属巧合还是我们是同事。但是我在我参加的课程中也有这个作业。删除并给客户端我已经实现的列表的方法是：

def do_DELETE(self):
    self.log_message('Incoming DELETE request...')

    try:
        name = parse_qs(self.path[2:])['name'][0]  
    except KeyError:
        self.send_response_to_client(404,self.path[2:])
        self.log_message("Incorrect parameters provided")
        return
        
    for key,value in names_dict.items():
        if name in names_dict.keys() or names_dict.values():
        
            if key == name:
                del names_dict[key]
                self.send_response_to_client(200,f'Name found and deleted {names_dict}')
                self.log_message("Name found and deleted")
                break
            elif value == name:
                del names_dict[key]
                self.send_response_to_client(200,f'Last Name found and deleted {names_dict}')
                self.log_message("Last Name found and deleted")
                
                break
    else:
        self.send_response_to_client(404,'Name does not exist')
        self.log_message("Name does not exist")
