新建FastApi项目
导入需要依赖
from fastapi import FastAPI, Request
from fastapi.responses import HTMLResponse
import requests
from jinja2 import Template
在项目根目录下新建templates文件夹以存储静态文件
在main.py下编写根据IP地址解析用户所在城市
代码语言：txt复制@app.get("/map", response_class=HTMLResponse)
async def root(request: Request):
# 获取用户IP地址
user_ip = "70.247.94.66"
# 使用百度地图API获取用户所在城市
baidu_api_key = "你自己的ak"
baidu_api_url = f"https://****?ak={baidu_api_key}&ip={user_ip}&coor=bd09ll"
response = requests.get(baidu_api_url)
city = response.json()["content"]["address_detail"]["city"]
x = response.json()["content"]["point"]["x"]
y = response.json()["content"]["point"]["y"]
# 生成HTML页面
with open("templates/index.html", "r") as f:
template = Template(f.read())
html = template.render(city=city,x=x,y=y)
# 返回HTML页面
return html编写前端html
