首先修改统一请求路径为我们自己的登陆接口,在.env.development文件中
# base api
VUE_APP_BASE_API = 'http://localhost:8081/api/dsxs/company'
打开登陆页面,src/views/login/index.vue
<template>
<div class="login-container">
<el-form ref="loginForm" :model="loginForm" :rules="loginRules" class="login-form" auto-complete="on" label-position="left">
<div class="title-container">
<h3 class="title">Login Form</h3>
</div>
<el-form-item prop="username">
<span class="svg-container">
<svg-icon icon-class="user" />
</span>
<el-input
ref="username"
v-model="loginForm.username"
placeholder="Username"
name="username"
type="text"
tabindex="1"
auto-complete="on"
/>
</el-form-item>
<el-form-item prop="password">
<span class="svg-container">
<svg-icon icon-class="password" />
</span>
<el-input
:key="passwordType"
ref="password"
v-model="loginForm.password"
:type="passwordType"
placeholder="Password"
name="password"
tabindex="2"
auto-complete="on"
@keyup.enter.native="handleLogin"
/>
<span class="show-pwd" @click="showPwd">
<svg-icon :icon-class="passwordType === 'password' ? 'eye' : 'eye-open'" />
</span>
</el-form-item>
<el-button :loading="loading" type="primary" style="width:100%;margin-bottom:30px;" @click.native.prevent="handleLogin">Login</el-button>
<div class="tips">
<span style="margin-right:20px;">username: admin</span>
<span> password: any</span>
</div>
</el-form>
</div>
</template>
可以看到页面使用组件对loginForm进行名称和密码的绑定
data() {
const validateUsername = (rule, value, callback) => {
if (!validUsername(value)) {
callback(new Error('Please enter the correct user name'))
} else {
callback()
}
}
const validatePassword = (rule, value, callback) => {
if (value.length < 6) {
callback(new Error('The password can not be less than 6 digits'))
} else {
callback()
}
}
这段代码则为对输入的内容进行验证
看登陆的方法
handleLogin() {
this.$refs.loginForm.validate(valid => {
if (valid) {
this.loading = true
this.$store.dispatch('user/login', this.loginForm).then(() => {
this.$router.push({ path: this.redirect || '/' })
this.loading = false
}).catch(() => {
this.loading = false
})
} else {
return false
}
})
}
其中 this.$store.dispatch('user/login', this.loginForm),不是请求后台user/login接口,而是转到modules下的user.js中的login方法,打开store/modules/user.js可以看到login方法。而login方法则是调用api/user.js中的login方法。
此时修改store/modules/user.js接收后台传来的响应数据
const actions = {
// user login
login({ commit }, userInfo) {
const { username, password } = userInfo
return new Promise((resolve, reject) => {
login({ username: username.trim(), password: password }).then(response => {
console.log(response)
const { data } = response
commit('SET_TOKEN', response.data.token)
setToken(response.data.token)
resolve()
}).catch(error => {
reject(error)
})
})
},
同时在api/user.js中修改为我们后台的请求地址
import request from '@/utils/request'
export function login(data) {
return request({
url: 'userlogin',
method: 'post',
data
})
}
export function getInfo(token) {
return request({
url: 'userinfo',
method: 'get',
params: { token }
})
}
此时可以发现模板采用的登陆方式是请求两次,第一次通过用户名密码请求后端,后端判断后,返回对应的token。然后在通过getInfo方法请求后端,获取用户真实信息。
在编写后端之前还需要修改utils/request.js,因为默认状态码是20000为成功,而我们平时返回的是200
// if the custom code is not 20000, it is judged as an error.
if (res.code !== 200) {
Message({
message: res.message || 'Error',
type: 'error',
duration: 5 * 1000
})
简单的编写后端代码,登陆方法根据账号密码查出用户信息,根据用户id与name生成token并返回,userinfo则是对token进行获取,在查出对应值进行返回。
@CrossOrigin
@RestController
@RequestMapping("/api/dsxs/company")
public class CompanyuserController {
@Autowired
private CompanyuserService companyuserService;
//后台登陆
@PostMapping("userlogin")
@ResponseBody
public R userlogin(@RequestBody UserVo userVo){
Companyuser companyuser = companyuserService.login(userVo);
String token = JwtHelper.createToken(companyuser.getId(), companyuser.getName());
return R.ok().data("token",token);
}
//返回信息
@GetMapping("userinfo")
public R userinfo( String token){
Integer userId = JwtHelper.getUserId(token);
System.out.println("====");
Companyuser user = companyuserService.getById(userId);
HashMap<String, String> map = new HashMap<>();
map.put("name",user.getName());
map.put("avatar",user.getAvatar());
return R.ok().data("name",user.getName()).data("avatar",user.getAvatar());
}
}
我这里使用@CrossOrigin注解解决的跨域问题。
