vue axios 请求带token设置

API axios.js
 
import axios from "axios";
let AUTH_TOKEN=(function(){
	return localStorage.getItem("token");
})();
 
var instance = axios.create({
});
instance.defaults.headers.common["Authorization"] = AUTH_TOKEN;
instance.interceptors.request.use(function(config){
	let url = config.url;
	if(url.indexOf("login")>-1){
		localStorage.setItem('token',"");
		config.headers.Authorization = "";
	}
	if(url.indexOf("user")>-1 && url.indexOf("login")<0){
		config.headers.Authorization =localStorage.getItem("token");
	}
	return config;
},function(err){
	return Promise.reject(err);
});
instance.interceptors.response.use(function(res){
	if(res.headers.token){
		localStorage.setItem('token',res.headers.token);
	}
	return res;
},function(err){
	return err;
});
export default instance;

　　

import axios from '@/api/axios'
 
 
export function loginBywx(){
	return axios.get('/api/v1/wechat/login')
	
}
 
export function login(params){
	return axios.post("/api/v1/user/info/login",params);
}
 
 
 
export function updateUser(params){
	return axios.put("/api/v1/user/info/update",params);
}

　　建一个请求前API的判断，在需要请求带token的地方引入
