vuex存储token示例

//根据api接口获取token 
var url = this.HOST + "/session"; 
this.$axios.post(url, { 
username: this.loginForm.username, 
password: this.loginForm.pass 
}).then(res => { 
// console.log(res.data); 
this.$message.success('登录成功'); 
let data = res.data; 
//根据store中set_token方法将token保存至localStorage/sessionStorage中，data["Authentication-Token"]，获取token的value值 
this.$store.commit('set_token', data["Authentication-Token"]); 
 
if (store.state.token) { 
this.$router.push('/') 
console.log(store.state.token) 
} else { 
this.$router.replace('/login'); 
} 
 
}).catch(error => { 
// this.$message.error(error.status) 
this.loading = false 
this.loginBtn = "登录" 
this.$message.error('账号或密码错误'); 
// console.log(error)
