如何在Python中处理POST和GET变量？

from flask import Flask, request

app = Flask(__name__)

# 处理GET请求
@app.route('/get', methods=['GET'])
def handle_get():
    name = request.args.get('name')  # 获取URL参数
    return f"GET参数: {name}"

# 处理POST请求（如表单提交）
@app.route('/post', methods=['POST'])
def handle_post():
    data = request.form.get('data')  # 获取表单数据
    return f"POST参数: {data}"

# 处理JSON格式的POST请求
@app.route('/json', methods=['POST'])
def handle_json():
    json_data = request.json  # 直接解析JSON
    return f"JSON数据: {json_data}"

if __name__ == '__main__':
    app.run()

from django.http import HttpResponse
from django.views import View

class GetView(View):
    def get(self, request):
        name = request.GET.get('name')  # GET参数
        return HttpResponse(f"GET参数: {name}")

class PostView(View):
    def post(self, request):
        data = request.POST.get('data')  # 表单数据
        return HttpResponse(f"POST参数: {data}")

    def post_json(self, request):
        import json
        json_data = json.loads(request.body)  # 手动解析JSON
        return HttpResponse(f"JSON数据: {json_data}")

from http.server import BaseHTTPRequestHandler
import urllib.parse

class Handler(BaseHTTPRequestHandler):
    def do_GET(self):
        query = urllib.parse.urlparse(self.path).query
        params = urllib.parse.parse_qs(query)  # 解析URL参数
        self.send_response(200)
        self.end_headers()
        self.wfile.write(f"GET参数: {params}".encode())

    def do_POST(self):
        content_length = int(self.headers['Content-Length'])
        post_data = self.rfile.read(content_length).decode()  # 读取请求体
        self.send_response(200)
        self.end_headers()
        self.wfile.write(f"POST数据: {post_data}".encode())
