膜拜下大神
登陆页面 src/views/login/index.js
element-ui表单,验证:http://element.eleme.io/#/zh-CN/component/form
vuex:https://vuex.vuejs.org/zh-cn/modules.html
##是否展示密码
showPwd() { //展示密码
if (this.passwordType === 'password') {
this.passwordType = ''
} else {
this.passwordType = 'password'
}
}
##点击登陆按钮
this.$router.push() 路由跳转:https://router.vuejs.org/zh-cn/essentials/navigation.html
handleLogin() {
this.$refs.loginForm.validate(valid => {
if (valid) { //验证通过
this.loading = true //按钮加载中
this.$store.dispatch('LoginByUsername', this.loginForm).then(() => {
// store/user.js/LoginByUsername //成功的情况
this.loading = false
this.$router.push({ path: '/' })
}).catch(() => {
this.loading = false
})
} else {
console.log('error submit!!')
return false
}
})
}
如果验证通过,那么就对用户名和密码进行检测
this.$store.dispatch: https://vuex.vuejs.org/zh-cn/actions.html (要学习action,mutations)
new Promise():https://www.liaoxuefeng.com/wiki/001434446689867b27157e896e74d51a89c25cc8b43bdb3000/0014345008539155e93fc16046d4bb7854943814c4f9dc2000
store/user.js/LoginByUsername
import { loginByUsername, logout, getUserInfo } from ‘@/api/login’
import { getToken, setToken, removeToken } from ‘@/utils/auth’
‘@/utils/auth’ //@指的是src
//通过Cookie.set设置
export function setToken(token) {
return Cookies.set(TokenKey, token)
}
//请求数据
export function loginByUsername(username, password) {
const data = {
username,
password
}
return request({ //向后台进行请求 类似于axios.post 详见下axios
url: '/login/login',
method: 'post',
data
})
/**
* 发送一个 POST 请求
axios({
method: 'post',
url: '/user/12345',
data: {
firstName: 'Fred',
lastName: 'Flintstone'
}
});
*/
}
// 用户名登录
LoginByUsername({ commit }, userInfo) {
const username = userInfo.username.trim() //处理传递过来的数据
//下面loginByUsername向后台发送username,userInfo.password获得登陆成功或失败的数据
//成功则设置SET_TOKEN
return new Promise((resolve, reject) => { //返回一个Promise对象
loginByUsername(username, userInfo.password).then(response => {
const data = response.data
commit('SET_TOKEN', data.token) //改变SET_TOKEN的值
setToken(data.token) // 通过 Cookies.set(TokenKey, token)
resolve()
}).catch(error => {
reject(error)
})
})
},
上面的作用:登陆的时候 在vuex中保存用户信息token,在cookie中保存用户信息token(权限)
##axios
地址:https://www.kancloud.cn/yunye/axios/234845
import axios from 'axios'
import { Message } from 'element-ui'
import store from '@/store'
import { getToken } from '@/utils/auth'
/*
export function getToken() {
return Cookies.get(TokenKey)
}
*/
// create an axios instance
//https://www.cnblogs.com/zhouyangla/p/6753673.html
//创建一个axios实例
const service = axios.create({ //自定义实例默认值
baseURL: process.env.BASE_API, // api的base_url
timeout: 5000 // request timeout
})
// request interceptor 添加请求拦截器
service.interceptors.request.use(config => {
// Do something before request is sent
if (store.getters.token) {
config.headers['X-Token'] = getToken() // 让每个请求携带token-- ['X-Token']为自定义key 请根据实际情况自行修改
}
return config
}, error => {
// Do something with request error
console.log(error) // for debug
Promise.reject(error)
})
// respone interceptor 添加响应拦截器
service.interceptors.response.use(
response => response, //成功
/**
* 下面的注释为通过response自定义code来标示请求状态,当code返回如下情况为权限有问题,登出并返回到登录页
* 如通过xmlhttprequest 状态码标识 逻辑可写在下面error中
*/
// const res = response.data;
// if (res.code !== 20000) {
// Message({
// message: res.message,
// type: 'error',
// duration: 5 * 1000
// });
// // 50008:非法的token; 50012:其他客户端登录了; 50014:Token 过期了;
// if (res.code === 50008 || res.code === 50012 || res.code === 50014) {
// MessageBox.confirm('你已被登出,可以取消继续留在该页面,或者重新登录', '确定登出', {
// confirmButtonText: '重新登录',
// cancelButtonText: '取消',
// type: 'warning'
// }).then(() => {
// store.dispatch('FedLogOut').then(() => {
// location.reload();// 为了重新实例化vue-router对象 避免bug
// });
// })
// }
// return Promise.reject('error');
// } else {
// return response.data;
// }
error => { //失败
console.log('err' + error) // for debug
Message({
message: error.message,
type: 'error',
duration: 5 * 1000
})
return Promise.reject(error)
})
export default service //导出 import request from '@/utils/request' 被命名为request
##中英文切换
学习:https://www.cnblogs.com/rogerwu/p/7744476.html
弹出框,确认框:http://element.eleme.io/#/zh-CN/component/message-box
mutations: {
TOGGLE_SIDEBAR: state => {
if (state.sidebar.opened) {
Cookies.set('sidebarStatus', 1)
} else {
Cookies.set('sidebarStatus', 0)
}
state.sidebar.opened = !state.sidebar.opened
},
SET_LANGUAGE: (state, language) => { //通过mutations来改变中英文状态
state.language = language
Cookies.set('language', language)
}
},
actions: {
toggleSideBar({ commit }) {
commit('TOGGLE_SIDEBAR')
},
setLanguage({ commit }, language) {
// 通过actions来改变中英文状态 (还是通过commit,调用mutations中的方法)
// 只是在这个方法中可以异步来改变
commit('SET_LANGUAGE', language)
}
}
export default {
computed: {
language() {
return this.$store.getters.language; //得到的语言
//getters是 state对象中的
}
},
methods: {
handleSetLanguage(lang) {
// this.$i18n.locale = lang //改变i18n语言种类
// this.$store.dispatch('setLanguage', lang)
// this.$message({
// message: 'switch language success',
// type: 'success'
// }) 这是添加了一个确认按钮,也要在语言/lang/en.js/cn.js添上对应的语言
this.$confirm(this.$t('confirm.tips'), this.$t('confirm.tips'), {
confirmButtonText: this.$t('confirm.sure'),
cancelButtonText: this.$t('confirm.no'),
type: 'warning'
})
.then(() => {
// let locale = this.$i18n.locale
// locale === 'zh' ? this.$i18n.locale = 'en' : this.$i18n.locale = 'zh'
this.$i18n.locale = lang; //改变i18n语言种类
this.$store.dispatch('setLanguage', lang);//dispatch 来触发action中
this.$message({
message: 'switch language success',
type: 'success'
});
})
.catch(() => {
this.$message({
message: 'switch language fail',
type: 'info'
});
});
}
}
};
###第三方登陆
el-dialog:http://element.eleme.io/#/zh-CN/component/dialog
import openWindow from '@/utils/openWindow'
export default {
name: 'social-signin',
methods: {
wechatHandleClick(thirdpart) {
this.$store.commit('SET_AUTH_TYPE', thirdpart) //作者未写此mutations
const appid = 'xxxxx'
const redirect_uri = encodeURIComponent('xxx/redirect?redirect=' + window.location.origin + '/authredirect')
const url = 'https://open.weixin.qq.com/connect/qrconnect?appid=' + appid + '&redirect_uri=' + redirect_uri + '&response_type=code&scope=snsapi_login#wechat_redirect'
openWindow(url, thirdpart, 540, 540)
},
tencentHandleClick(thirdpart) {
this.$store.commit('SET_AUTH_TYPE', thirdpart)
const client_id = 'xxxxx'
const redirect_uri = encodeURIComponent('xxx/redirect?redirect=' + window.location.origin + '/authredirect')
const url = 'https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=' + client_id + '&redirect_uri=' + redirect_uri
openWindow(url, thirdpart, 540, 540) //打开一个浏览器窗口
}
}
}
例如点击微信图标
