vue axios 跨域，攜帶cookie

前端設定 axios 跨域

const axios = require("axios")
axios.defaults.withCredentials=true
           

後端設定:

express

...

  app.use('*', function(req, res, next) {
    res.setHeader("Access-Control-Allow-Origin", req.headers.origin);
    res.setHeader("Access-Control-Allow-Credentials","true")
    res.setHeader("Access-Control-Allow-Headers", "Content-Type");
    res.setHeader("Access-Control-Allow-Methods","*")
    if(req.method==='OPTIONS'){
      res.sendStatus(204)
      return
    }
    next();
  });
  
...
           

Nest.js

...
  //開啟跨域
  app.enableCors({
  	// 自動适配相應頭："Access-Control-Allow-Origin"
  	// origin:true === res.setHeader("Access-Control-Allow-Origin", req.headers.origin);
    origin: true,
    //請求方式
    methods: "*",
    preflightContinue: false,
    //快速響應 OPTIONS 請求
    optionsSuccessStatus: 204,
    //攜帶 cookie
    credentials:true
  });
