Flask MethodView 中 'get()' 方法缺少参数 'args' 的错误解决

///'from flask.views import MethodView//nfrom flask_smorest import Blueprint//n@blp.route(/'/hello/')//n# class UploadView(JwtView)://nclass UploadHelloView(MethodView)://n def get(self,args)://n print(/'args=/',args)//n print(/'get=/', request.args)//n return ///'hello+get///'//n//n为什么这样写，会报错 get() missing 1 required positional argument: 'args'/'//n///'这个错误是因为在方法get()中缺少一个必需的位置参数args。根据你的代码，args是从URL中传递进来的参数，但是在Flask的MethodView中，方法的参数默认是从请求的URL中获取的。所以你可以像下面这样修改代码：//n//npython//nfrom flask import request//nfrom flask.views import MethodView//nfrom flask_smorest import Blueprint//n//n@blp.route(/'/hello/')//nclass UploadHelloView(MethodView)://n def get(self)://n args = request.args//n print(/'args =/', args)//n return ///'hello+get///'//n//n//n这样修改后，你就可以通过request.args获取到URL中传递过来的参数了。//n/
