django rest_framework vue 實現用戶登陸

django rest_framework vue 實現用戶登陸

後端代碼就不介紹了，能夠參考  django rest_framework 實現用戶登陸認證

 

這裏介紹一下前端代碼，和先後端的聯調過程

在components下新建login.vue 文件

<template>
    <div class="login">
      <el-form label-width="80px">
        <el-form-item label="用戶名">
          <el-input v-model="form.username"></el-input>
        </el-form-item>
        <el-form-item label="密碼">
          <el-input v-model="form.password" type="password"></el-input>
        </el-form-item>
        <el-form-item>
          <el-button type="primary" @click="onLogin">登陸</el-button>
          <el-button>取消</el-button>
        </el-form-item>
      </el-form>
    </div>
</template>

<script> import axios from 'axios'; export default { name: "login", data() { return { form: { username: null, password: null } } }, methods: { onLogin() { axios.post('http://127.0.0.1:8000/api/v1/auth/',this.form,{withCredentials:true}).then((res)=> { console.log(res); this.$router.go({path:'/'}); }); } } } </script>

<style scoped> .login { width: 50%; margin: 0 auto;
}
</style>

 

修改rounter下index.js

import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld' import test from '@/components/test' import runoob from '@/components/runoob' import vhtml from '@/components/vhtml' import Login from '@/components/login' Vue.use(Router) var router = new Router({ routes: [ { path: '/', name: 'HelloWorld', component: HelloWorld }, { path: '/test', name: 'test', component: test } , { path: '/login', name: 'login', component: Login } , { path: '/runoob', name: 'runoob', component: runoob }, { path: '/vhtml', name: 'vhtml', component: vhtml }, ] }) router.beforeEach((to,from,next)=> { if(to.path==='/login') { window.hideLogin = false; } // if(!window.token&&to.path!=='/login') { // router.go('/login'); // }else { // next(); // } next(); }) export default router;

 

修改項目 man.js

// The Vue build version to load with the `import` command // (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue' import App from './App' import router from './router' import ElementUI from 'element-ui' import axios from 'axios' Vue.prototype.axios = axios Vue.config.productionTip = false Vue.use(ElementUI); // 引入elementui

/* eslint-disable no-new */
new Vue({ el: '#app', router, components: { App }, template: '<App/>' })

 

啓動項目 npm run dev

 

輸入url,訪問查看頁面 

 

啓動服務端

 

瀏覽器打開檢查功能

數據用戶名和密碼，點擊登陸 以下圖。

 

由於還沒作登陸跳轉頁。因此 先經過這種方式，檢驗是否登陸成功。

查看後臺返回信息

 

 

 遇到的問題：

一、跨域問題

由於vue 和django項目是兩個先後端獨立的項目，分別啓動後，存在端口不一致的跨域問題。

如這裏vue端口是8080，django 是8000,會一直存在找不到服務的問題。

 解決方法：修改jango  settings.py 文件

首先安裝 corsheaders

 

# 安裝
 pip install django-cors-headers

 

# 添加 corsheaders 應用 # Application definition
 INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'api', 'corsheaders',  # 解決跨域問題 修改1
]

 

# 中間層設置

 

# 添加以下
MIDDLEWARE = [ ... 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', ... ]

# CORS 設置跨域域名 配置白名單
CORS_ORIGIN_WHITELIST = [ "https://example.com", "https://sub.example.com", "http://localhost:8080", "http://localhost:8000", "http://127.0.0.1:8000" ]

 

#直接容許全部主機跨域
 CORS_ORIGIN_ALLOW_ALL = True 默認爲False

CORS_ALLOW_CREDENTIALS = True # 容許攜帶cookie

 

# 下面這兩個設置 經測試無用 

# # # 解決跨域問題 修改5 # CORS_ALLOW_METHODS = ( # 'DELETE', # 'GET', # 'OPTIONS', # 'PATCH', # 'POST', # 'PUT', # 'VIEW', # )

# # 解決跨域問題 修改6 # CORS_ALLOW_HEADERS = ( # 'XMLHttpRequest', # 'X_FILENAME', # 'accept-encoding', # 'authorization', # 'content-type', # 'dnt', # 'origin', # 'user-agent', # 'x-csrftoken', # 'x-requested-with', # 'Pragma', # )

二、ESlint代碼檢測，啓動vue時系統報錯錯誤警告

解決方式

一、若是對本身信不過。最好的辦法就是建立項目的時候不要ESlint 直接N

 

二、註釋掉ESlint

 

在本身的項目目錄下build.js——webpack.base.conf.js文件裏面有段代碼註釋掉就行
