基于请求正文的路由请求url？

Question

我如何根据flask中的请求主体路由请求？我想我可以使用redirect，但我不喜欢使用它，而是根据正文的内容立即路由请求

以下是我尝试但失败的内容：

# I am using Flask-restful extension
from flask import Flask, request
from flask_restful import Resource, Api

class RouteA:
    def post(self):
        return {'route': 'RouteA'}
class RouteB:
    def post(self):
        return {'route': 'RouteB'}

app = Flask(__name__)
api = Api(app) # This is just flask-restful app wrapper extension

# I am trying to use before_request
@app.before_request
def routing():
    request_body = request.get_json(force=True)
    type = request_body.get('type', None)
    if type and type == 'RouteB':
        # somehow direct to routeB
        request.path = '/jobs/routeb'
        # I can do this too but I prefer direct routing rather than redirecting
        # return redirect(location='jobs/routeb', code=307)


# routing here
api.add_resource(RouteA, '/jobs')
api.add_resource(RouteB, '/jobs/routeb')

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

我将如何向该端点发出请求：

import requests

url = 'http://localhost:5000/jobs'

payload = {
    'type': 'RouteB'
}

r = requests.post(url=url, json=payload)
response = r.json()
print(response)
# Expecting:
# {'route': 'RouteB'}
