解決nodejs中cros跨域cookie和session失效的問題

nodejs端

const cors = require('cors');
var app=express();

var corsOptions = {
  origin: 'http://localhost:8080',
  credentials: true,
  maxAge: '1728000'
  //這一項是爲了跨域專門設置的
}
app.use(cors(corsOptions))

前端

1.vue-resource

this.$http.get('getlogin',{ credentials: true }).then(res => {
                    console.log(res)
                })

this.$http.post('postlogin',{userInfo: $('.form-signin').serialize()},{ credentials: true }).then(res => {
                    console.log(res)
                    if(res.body.status != 200) {
                        console.log('登陸失敗')
                    }else {
                        console.log('登陸成功')
                    }
                })

2.原生js中api

var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://www.xxx.com/api');
xhr.withCredentials = true;
xhr.onload = onLoadHandler;
xhr.send()

3.jquery中

$.ajax({
            url: "http://localhost:8080/orders",
            type: "GET",
            xhrFields: {
                withCredentials: true
            },
            crossDomain: true,
            success: function (data) {
                render(data);
            }
 });

4.axios

const service = axios.create({
  baseURL: process.env.BASE_API, // node環境的不一樣，對應不一樣的baseURL
  timeout: 5000, // 請求的超時時間
  //設置默認請求頭，使post請求發送的是formdata格式數據// axios的header默認的Content-Type好像是'application/json;charset=UTF-8',個人項目都是用json格式傳輸，若是須要更改的話，能夠用這種方式修改
  // headers: {  
    // "Content-Type": "application/x-www-form-urlencoded"
  // },
  withCredentials: true // 容許攜帶cookie
})
