Vercel 后端上手

热知识: Vercel 支持后端，可以使用 Flask 语法 （

准备工作:

• Flask

• 一个自己的域名

• 一个 Vercel 账号，并且绑定 Github

新建文件夹

将文件夹放入以下文件:

• requirements.txt

• vercel.json

• index.py

requirements.txt:

Flask
requests
pyjson
pyrandom

告诉 Vercel 要引入的库，如果要引入其它库请自行搜索。

vercel.json

{
  "builds": [
    {
      "src": "./index.py",
      "use": "@vercel/python"
    }
  ],
  "routes": [
    {
      "src": "/(.*)",
      "headers": {
        "cache-control": "no-cache, no-store, must-revalidate",
        "Access-Control-Allow-Origin": "*"
      },
      "dest": "/"
    }
  ]
}

index.py 以跳转到一个网站为例

from flask import Flask , request , jsonify, redirect, url_for
import requests , json , random
app = Flask(__name__)
app.config['JSON_AS_ASCII'] = False

@app.route('/',methods=["GET"])
def root():
    return redirect('https://www.acerkaio.top/')

实现随机图

from flask import Flask , request , jsonify, redirect, url_for
import requests , json , random
app = Flask(__name__)
app.config['JSON_AS_ASCII'] = False

@app.route('/',methods=["GET"])
def root():
    return redirect('https://pixiv.acerkaio.top/')

@app.route('/rd',methods=["GET"])

def rdom():

    url = f'https://data.acerkaio.top/elaina.json' #改成你的 url
