Python 访问烧瓶中的积垢端点时出现问题

我创建了一个CRUD端点，但当我尝试获取数据时，收到一个404错误。我尝试使用和访问此端点，但仍然得到404。因为我提供了“beck”作为艺术家的名字，所以我认为get方法可以正常运行。我想我添加的资源不正确

class Artistdetails(Resource):
    def get(self, artist_name):
        conn = db_connect.connect()
        # Protect against SQL injection
        restricted_char = "!=<>*0&|/\\"
        for char in restricted_char:
            artist_name = artist_name.replace(char, "")
        query_db = conn.execute("SELECT DISTINCT album FROM album WHERE artist='{0}'".format(artist_name.title()))
        result = jsonify({'artistAlbumList': [i[0] for i in query_db.cursor.fetchall()]})
        return result

    def put(self, artist_name, album_name, album_name_new):
        conn = db_connect.connect()
        # Protect against SQL injection
        restricted_char = "!=<>*0&|/\\"
        for char in restricted_char:
            artist_name = artist_name.replace(char, "")
        query_db = conn.execute("UPDATE album SET album='{0}' WHERE artist='{1}' AND"
                                " album='{2}'".format(artist_name.title(), album_name.title(), album_name_new.title()))
        result = jsonify({'putAlbumId': [i[0] for i in query_db.cursor.fetchall()]})
        return result, 201

    def post(self, artist_name, album_name):
        conn = db_connect.connect()
        # Protect against SQL injection
        restricted_char = "!=<>*0&|/\\"
        for char in restricted_char:
            artist_name = artist_name.replace(char, "")
        query_db = conn.execute("INSERT INTO album (album, artist) VALUES"
                                " ({0},{1})".format(artist_name.title(), album_name.title()))
        result = jsonify({'postAlbumId': [i[0] for i in query_db.cursor.fetchall()]})
        return result, 201

    def delete(self, artist_name, album_name):
        conn = db_connect.connect()
        # Protect against SQL injection
        restricted_char = "!=<>*0&|/\\"
        for char in restricted_char:
            artist_id = artist_name.replace(char, "")
            album_id = album_name.replace(char, "")
        query_db = conn.execute("DELETE FROM album WHERE"
                                " artist_id='{0}' AND album_id='{1}'".format(artist_name, album_name)
                                )
        result = jsonify({'deleteAlbumId': [i[0] for i in query_db.cursor.fetchall()]})
        return result, 204

创建API路由 这一行：

api.add_resource(Artistdetails,
    '/albums/<string:artist_name>/<string:album_name>/<string:album_name_new>')

---

它向Flask路由器添加了一条路径，使其预期/albums/会有用。

@Birryrree是否可以为get、post、put和delete添加不同数量的参数？或者这就是reqparse的用武之地？@PanczerTank对于get等请求的不同数量的参数，您可以使用reqparse，尽管它已被弃用，但您仍然可以使用它或类似棉花糖的东西。对于其他方面，您可以创建新端点并将它们绑定到同一个类。Flask RESTful看起来应该只将一个端点绑定到一个类，但事实并非如此。您可以根据需要将同一类附加到多个资源。

api.add_resource(Artistdetails,
    '/albums/<string:artist_name>/<string:album_name>/<string:album_name_new>')

api.add_resource(Artistdetails, '/albums/<string:artist_name>')

/albums?artist=<string>&album_name=<string>
