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

@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
