我正在努力让我的脚湿在API开发。我的大部分笔记都是从学校里记的

到目前为止,我对

请求返回一个
404
错误

下面是我正在练习的API代码:

class UserAPI(Resource):
    def __init__(self):
        self.reqparse = reqparse.RequestParser()
        self.reqparse.add_argument('name', type = str, required = True, help = "No name provided", location = 'json')
        self.reqparse.add_argument('email', type = str, required = True, help = "No email provided", location = 'json')
        self.reqparse.add_argument('password', type = str, required = True, help = "No password provided", location = 'json')
        super(UserAPI, self).__init__()

    def get(self, id):
        if checkUser(id):          #Just checks to see if user with that id exists
            info = getUserInfo(id) #Gets Users info based on id
            return {'id': id, 'name': info[0], 'email':info[1], 'password': info[2], 'role': info[3]}
        abort(404)

    def put(self, id):
        if checkUser(id):
            args = self.reqparse.parse_args()
            deleteUser(id)      #Deletes user with this id
            addUser(User(args['name'], args['email'], args['password'], args['role']))  #Adds user to database 
        abort(404)

    def delete(self, id):
        deleteUser(id)
        return { 'result': True}

class UserListAPI(Resource):
    def __init__(self):
        self.reqparse = reqparse.RequestParser()
        self.reqparse.add_argument('name', type = str, required = True, help = "No name provided", location = 'json')
        self.reqparse.add_argument('email', type = str, required = True, help = "No email provided", location = 'json')
        self.reqparse.add_argument('password', type = str, required = True, help = "No password provided", location = 'json')
        self.reqparse.add_argument('role', type = bool, default = 0, location = 'json')
        super(UserListAPI, self).__init__()

    def get(self):
        return { 'users': map(lambda u: marshal(u, user_fields), getAllUsers()) }

    def post(self):
        print self.reqparse.parse_args()
        args = self.reqparse.parse_args()
        new_user = User(args['name'], args['email'], args['password'], args['role'])
        addUser(new_user)
        return {'user' : marshal(new_user, user_fields)}, 201 

api.add_resource(UserAPI, '/api/user/<int:id>', endpoint = 'user')
api.add_resource(UserListAPI, '/api/users/', endpoint = 'users')
这对我来说毫无意义。
不应该接受我放在URL末尾的整数吗

谢谢你的任何想法


编辑

在我被指出一个愚蠢的错误后更新我的答案。现在,put方法如下所示:

def put(self, id):
    if checkUser(id):
        args = self.reqparse.parse_args()
        deleteUser(id)
        user = User(args['name'], args['email'], args['password'], args['role'])
        addUser(user)
        return {'user' : marshal(user, user_fields)}, 201 
    else:
        abort(404)

当PUT成功时,您不会返回,所以总是中止(404)。 与其他HTTP谓词类似:

def put(self, id):
        if checkUser(id):
            args = self.reqparse.parse_args()
            deleteUser(id)      #Deletes user with this id
            addUser(User(args['name'], args['email'], args['password'], args['role']))
            # Missing return when succees
        abort(404) # Always executing
编辑:我已经测试了您的示例(使用一些额外的代码使其工作,例如导入和删除未实现的特定代码)。这是我的代码:

from flask import Flask

        self.reqparse.add_argument('password', type = str, required = True, help = "No password provided", location = 'json')

所以我鼓励你检查我删除的那些方法。。。就像checkUser(id)

当PUT成功时,您不会返回,所以总是中止(404)。 与其他HTTP谓词类似:

def put(self, id):
        if checkUser(id):
            args = self.reqparse.parse_args()
            deleteUser(id)      #Deletes user with this id
            addUser(User(args['name'], args['email'], args['password'], args['role']))
            # Missing return when succees
        abort(404) # Always executing
