我有一个python flask脚本,其中包含我开发的JSON。
我正在尝试使用以下url返回城市:
http://127.0.0.1:5000/restaurant/city
.
我发现了一个错误:
内部服务器错误服务器遇到内部错误
无法完成您的请求。要么服务器超载,要么
应用程序中有一个错误。
我不确定代码中的逻辑错误在哪里。
有人能帮我吗?
我正在使用python 3.8和flask。
以下是我的代码(代码中包含json):
from flask import Flask, jsonify, request
import json
# from urllib3 import request
# import urllib.request as urllib
app = Flask(__name__)
