解决nodejs中cors跨域cookie和session失效的问题
1、nodejs端
-
安装cors:npm i cors -s
-
配置:
const cors = require('cors'); // 初始化 express 实例 var app = express(); var corsOptions = { origin: 'http://localhost:8080', credentials: true, maxAge: '1728000' } app.use(cors(corsOptions))
2、前端
2.1、原生js
var xhr = new XMLHttpRequest()
xhr.open('GET','http://localhost:8080')
xhr.withCredentials = true
xhr.onload = onLoadHandler
xhr.send()
2.2、jquery
$.ajax({
url: `http://localhost:8001/api/blog/list`,
type: 'GET',
xhrFields: {
withCredentials: true
},
crossDomain: true,
headers: {
'content-type': 'application/json'
},
data: {},
success: function (res) {
console.log(res);
},
error: function (err) {
console.log(err)
}
})
2.3、vue-resource
this.$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('登录失败')
}else {
console.log('登录成功')
}
})
2.4、axios
const service = axios.create({
baseURL: process.env.BASE_API, // node环境的不同,对应不同的baseURL
timeout: 5000, // 请求的超时时间
//设置默认请求头,使post请求发送的是formdata格式数据// axios的header默认的Content-Type好像是'application/json;charset=UTF-8',我的项目都是用json格式传输,如果需要更改的话,可以用这种方式修改
// headers: {
// "Content-Type": "application/x-www-form-urlencoded"
// },
withCredentials: true // 允许携带cookie
})
