Flask 400 错误请求 KeyError

如何解决Flask 400 错误请求 KeyError

我的烧瓶服务器代码是这样的，

from flask import Flask,request

app = Flask(__name__)

todos = {}

@app.route('/<todo_id>',methods=['GET','PUT','DELETE'])
def main(todo_id):
  if request.method == 'GET':
    try:
      return {todo_id: todos[todo_id]}
    except:
      return {"status": "paused or off"}
  elif request.method == 'DELETE':
    if todo_id in todos:
      del todos[todo_id]
      return '',204
    else:
      return '',404
  elif request.method == 'PUT':
      json = {"modules": request.form['modules'],"hits":request.form['hits'],"customs":request.form['customs'],"free":request.form['free'],"bads":request.form['bads'],"checked":request.form['checked'],"remaining":request.form['remaining'],"retries":request.form['retries'],"errors":request.form['errors'],"cpm":request.form['cpm']
      }
      print(1)
      todos[todo_id] = json
      print(1)
      return {todo_id: todos[todo_id]}

if __name__ == '__main__':
  app.run(host="0.0.0.0",port=8080,debug=True)

我的客户端代码是这样的，

import requests

params = (
    ('cpm','123'),("modules","doordash|COD"),("hits",'63242'),("customs","888"),("free","233"),("bads","3892"),("checked",'20000'),("remaining",'200000'),("retries","1000"),("errors",'1234')
        )
response = requests.put('https://animeaskedforitt.my name.repl.co/123?modules=edigubv',params=params)
print(response)
r = requests.get("https://animeaskedforitt.myname.repl.co/123").text
print(r)

每次运行它时，我都会收到来自 put 请求的 500 错误和 200 成功代码。

在控制台中，我收到一个 400 错误，指出“错误的请求”和 KeyError: module 的 python 错误
