我正在尝试创建一个简单的API来返回JSON中的GET和表中的数据，其中的数据库是pgsql，但是当我执行CURL时，我会得到错误500
烧瓶.py
from flask import Flask, request, jsonify
from flask_restful import Resource, Api
from sqlalchemy import create_engine
from json import dumps
import psycopg2
db_connect = create_engine('postgresql+psycopg2://postgres:postgres@localhost/dbname')
app = Flask(__name__)
api = Api(app)
class ApiZabbix(Resource):
def getMemory(self):
try:
conn = db_connect.connect()
query = conn.execute("select * from "TBLNAME"")
result = [dict(zip(tuple(query.keys()), i)) for i in query.cursor]
return jsonify(result)
except Exception as e:
print("[ALERT] Error caused by: {}".format(e))
api.add_resource(ApiZabbix, '/apizb')
if __name__ == '__main__':
app.run()
卷曲
curl localhost:5000/apizb
输出

断言错误：未实现的方法"GET">
这意味着您的ApiZabbix类需要一个get方法。因此，与其调用该方法getMemory，不如将其重命名为get:
class ApiZabbix(Resource):
def get(self):
