关于前端vue项目设置请求头权限问题

关于前端vue项目设置请求头权限问题

新建一个公共js文件。如： lp.js.

//设置请求消息头

export function headers(contentType,token){
let headers={};
headers['Content-Type'] = contentType ? contentType : 'application/json;charset=utf-8';
let a = window.location.href;
let b = a.indexOf("#");
let loginUrl = a.substring(b+2);
if(loginUrl){
localStorage.loginUrl = loginUrl;
}
let url = a.substring(0,b+2);
if(loginUrl==='login' || loginUrl==='reg' || loginUrl==='phoneAuth' || loginUrl=='emailInfo'){
token='';
}else{
token=window.localStorage.getItem('jingjing_login_token');
}
token = token ? token : '';

let key = 'jmjbGEWO4EyItpA4';
let current_timestamp = new Date().getTime() + '';
let nonce_str = getNonceStr(32);

let lp_sign = sign(token, current_timestamp, nonce_str, key);
headers['token'] = token;
headers['current-timestamp'] = current_timestamp;
headers['nonce-str'] = nonce_str;
headers['lp-sign'] = lp_sign;
return headers;

}
//生成随机字符串
export function getNonceStr(len) {
len = len || 32;
let chars = '1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
let maxPos = chars.length;
let s = '';
for (let i = 0; i < len; i++) {
s += chars.charAt(Math.floor(Math.random() * maxPos));
}
return s;
}

//  在组件中使用直接引用，
import {headers} from '@/assets/js/common/lp.js'

methods: {
// 获取员工架构
getTree() {
// that.$emit('updataTree')
let that = this
this.$http({
method:"get",
url:api.treeList,
**headers:headers('application/json;charset=utf-8'),**
cache:false
}).then(function(res){
if(res.data.code==10000 || res.data.data==null){
that.treeDatas = res.data.data
console.log(that.treeDatas,'<//====treeDatas')
}else{
that.$message.error(res.data.msg);
}
});
},
}

其中api.js中这么定义
let Butterfly="http://192.168.6.207:8891/jersey/";//xxip

const api = {
baseUrl:Butterfly,
treeList:Butterfly+'enterpriseInfo/current/user',
};
export default api;

当然在路由请求时需要设置，在router.js文件中
router.beforeEach((to, from, next) => {
if(!localStorage.jingjing_login_token && to.path!=='/' && to.name !== 'phoneAuth' && to.name !== 'reg' && to.name !== 'agree'  && to.name !== 'restPsd' && to.name !== 'ablityAssessment' && to.name !== 'leaveAssessment' && to.name !== 'contact' && to.name !== 'wasAsked' && to.name !== 'newWitesite_index' && to.name !== 'bySinging' && to.name !== 'brokenQuery' && to.name !== 'login'){
router.push({path:'/login'});
}else{
let a = window.location.href;
let b = a.indexOf("#");
let loginUrl = a.substring(b+2);
if(loginUrl){
localStorage.loginUrl = loginUrl;
}
next();
}
});
export default router;
