python中localhost上的HTTP删除请求

Question

我正在尝试在localhost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, 
Response status_code: {}, Response data: {}".format(r.status_code, r.text))
r = requests.delete("http://127.0.0.1:8080/", params={'name':'chris', 'last_name':'lee'})
print("Request method: DELETE, 
Response status_code: {}, Response data: {}".format(r.status_code, r.text))

我如何在服务器文件中添加代码，根据名称和last_name从字典中删除条目，然后像发布请求后一样在屏幕上打印新字典。

我不知道这是纯粹的巧合还是我们是同事。但在我学习的课程中，我也有这个任务。删除并向客户端提供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")
