Python 3 Flask Rest API 获取多个参数

Question

如何在带有多个参数的python上获得rest api？我通过以下网址在 IE 上测试了我的 rest api

http://127.0.0.1:5002/search_np?item=testing&posn=1

from flask import Flask, request
from flask_restful import Resource, Api
from flask_cors import CORS

....

app = Flask(__name__)
cors = CORS(app, resources={r"*": {"origins": "*"}})
api = Api(app)
api.add_resource(search_nextpage, '/search_np')

....
class search_nextpage(Resource):
    def get(self):
        search_item = request.args.get('item', "")
        search_posn =request.args.get('posn', "")

from flask import Flask, request
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app)


class search_nextpage(Resource):
    def get(self):
        item = request.args.get('item')
        posn = request.args.get('posn')
        return {'item': item, 'posn': posn}


api.add_resource(search_nextpage, '/search_np')

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

请求http://127.0.0.1:5000/search_np?item=chocolate&posn=0 会产生以下输出。

{
    "item": "chocolate",
    "posn": "0"
}

参数 item 和 posn 从查询字符串中检索并在 json 字典中返回。
