Vue、SPA实现登陆

axios/qs/vue-axios安装及使用步骤

首先我们要下载三个依赖包，方便后面的开发使用需要：

npm install axios -S   axios是vue2提倡使用的轻量版的ajax。它是基于promise的HTTP库。它会从浏览器中创建XMLHttpRequests，与Vue配合使用非常好。

npm install qs -S   qs 是用来转换格式的

npm install vue-axios -S  是一个插件基于axios 

npm install element-ui -S  下载element-ui模块（因为之前下过了所以这里就没截图啦）

既然下载了那么在项目中也要引用相对应的依赖

action.js(简单来说就是连接后台的方法)

/**
 * 对后台请求的地址的封装，URL格式如下：
 * 模块名_实体名_操作
 */
export default {
    'SERVER': 'http://localhost:8080/T216_SSH', //服务器
    'SYSTEM_USER_DOLOGIN': '/vue/userAction_login.action', //用户登陆
    'SYSTEM_USER_DOREG': '/vue/userAction_reg.action', //用户注册
    'SYSTEM_MENU_TREE': '/vue/treeNodeAction.action', //左侧树形菜单加载
    'SYSTEM_ARTICLE_LIST': '/vue/articleAction_list.action', //文章列表
    'SYSTEM_ARTICLE_ADD': '/vue/articleAction_add.action', //文章新增
    'SYSTEM_ARTICLE_EDIT': '/vue/articleAction_edit.action', //文章修改
    'SYSTEM_ARTICLE_DEL': '/vue/articleAction_del.action', //文章删除
    'SYSTEM_USER_GETASYNCDATA': '/vue/userAction_getAsyncData.action', //vuex中的异步加载数据
    'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用
        return this.SERVER + this[k];
    }
}

http.js(连接后台的关键)

/**
 * vue项目对axios的全局配置
 */
import axios from 'axios'
import qs from 'qs'

//引入action模块，并添加至axios的类属性urls上
import action from '@/api/action'
axios.urls = action

// axios默认配置
axios.defaults.timeout = 10000; // 超时时间
// axios.defaults.baseURL = 'http://localhost:8080/j2ee15'; // 默认地址
axios.defaults.baseURL = action.SERVER;

//整理数据
// 只适用于 POST,PUT,PATCH，transformRequest` 允许在向服务器发送前，修改请求数据
axios.defaults.transformRequest = function(data) {
  data = qs.stringify(data);
  return data;
};

// 请求拦截器
axios.interceptors.request.use(function(config) {
  // var jwt = window.vm.$store.getters.getJwt;
  // config.headers['jwt'] = jwt;
  return config;
}, function(error) {
  return Promise.reject(error);
});

// 响应拦截器
axios.interceptors.response.use(function(response) {
  // debugger;
  // var jwt = response.headers['jwt'];
  // if(jwt){
  //     window.vm.$store.commit('setJwt',{jwt:jwt});
  // }
  return response;
}, function(error) {
  return Promise.reject(error);
});

// // 路由请求拦截
// // http request 拦截器
// axios.interceptors.request.use(
//     config => {
//         //config.data = JSON.stringify(config.data);
//         //config.headers['Content-Type'] = 'application/json;charset=UTF-8';
//         //config.headers['Token'] = 'abcxyz';
//         //判断是否存在ticket，如果存在的话，则每个http header都加上ticket
//         // if (cookie.get("token")) {
//         //     //用户每次操作，都将cookie设置成2小时
//         //     cookie.set("token", cookie.get("token"), 1 / 12)
//         //     cookie.set("name", cookie.get("name"), 1 / 12)
//         //     config.headers.token = cookie.get("token");
//         //     config.headers.name = cookie.get("name");
//         // }
//         return config;
//     },
//     error => {
//         return Promise.reject(error.response);
//     });

// // 路由响应拦截
// // http response 拦截器
// axios.interceptors.response.use(
//     response => {
//         if (response.data.resultCode == "404") {
//             console.log("response.data.resultCode是404")
//             // 返回 错误代码-1 清除ticket信息并跳转到登录页面
//             //      cookie.del("ticket")
//             //      window.location.href='http://login.com'
//             return
//         } else {
//             return response;
//         }
//     },
//     error => {
//         return Promise.reject(error.response) // 返回接口返回的错误信息
//     });
export default axios;

既然前后连接完了，咱就来玩玩联合登陆吧

 

先给登陆页面来个它该有的亚子，这里楼楼从element框架里面复制过来改了一下

就长这样，还不错吧简单大气

在这里要提一下提交方式，众所周知最普遍使用的就是get和post方法所以我现在也是来给你们看一下两种提交方式的不同

Post提交方式

 

axios.post(url, qs.stringify(this.ruleForm)).then((response) => {
        
                  console.log(response);
                  if (response.data.code == 1) {
                    this.$message({
                      message: response.data.msg,
                      type: 'success'
                    });
                  } else {
                    this.$message({
                      showClose: true,
                      message: response.data.msg,
                      type: 'error'
                    });
                  }
        
                }).catch(function(error) {
        
                  console.log(error);
        
                });

 

别找了 我Login.vue里面用的就是get提交

大家都知道vue好就好在他是Spa路由模式，所以还要给他配置一下路径（让它可以一个页面跳转多个页面）

   

这可别找错了 router==>index.js

index.js

 

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Login from '@/view/Login'  //登陆
import Reg from '@/view/Reg'     //注册
Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'Login',
      component: Login
    },
        {
            path: '/Login',
            name: 'Login',
            component: Login
        },
    {
      path: '/Reg',
      name: 'Reg',
      component: Reg
    }
  ]
})

 

配置入口文件 main.js

在项目中src目录下找到main.js，并在指定位置添加三行代码（main.js是入口文件，所以在这里引入就行，页面就不用引入了）
import Vue from 'vue'

import ElementUI from 'element-ui' //新添加1
import 'element-ui/lib/theme-chalk/index.css' //新添加2，避免后期打包样式不同，要放在import App from './App';之前

import App from './App'
import router from './router'

Vue.use(ElementUI) //新添加3
Vue.config.productionTip = false

 

　　注意：要在指定位置！

// 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 'element-ui/lib/theme-chalk/index.css'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'
import axios from '@/api/http'
import VueAxios from 'vue-axios'
Vue.use(ElementUI)
Vue.use(VueAxios,axios)
Vue.config.productionTip = false

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

 

问题：

注1：axios跨域问题
会一直报错：“http://127.0.0.1:8848' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header”
因为使用了前后端分离开发，跨域访问了，解决方案：需要配置tomcat允许跨域访问，
tomcat跨域配置方法很多，但最简单的方式是自己写一个过滤器CorsFilter实现，添加一个响应头
Access-Control-Allow-Origin即可
httpResponse.addHeader("Access-Control-Allow-Origin", "*");//*表示任何域名
httpResponse.addHeader("Access-Control-Allow-Origin", "http://localhost:80");

Access-Control-Allow-Origin:* #则允许所有域名的脚本访问该资源。
Access-Control-Allow-Origin:https://www.fujieace.com #允许特定的域名访问

 

 

注2：axios.get提交没有问题，axios.post提交后台接收不到数据
因为POST提交的参数的格式是Request Payload，这样后台取不到数据的(详情见资料“05 Vue中axios踩坑之路-POST传参 - RainSun - CSDN博客.mht”)，
解决方案：使用qs.js库，将{a:'b',c:'d'}转换成'a=b&c=d'

 

 

注3：为简化axios使用，还可以使用axios全局配置及拦截器，详情见资料“api/http.js”
axios.defaults.baseURL = 'https://api.example.com';
//axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;//自定义请求头，添加认证令牌
axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';

 

 

注4：为方便开发，建议对请求地址进行封装，详情见资料“api/action.js”

注5：^_^~~~~为进一步简化开发，将action.js的URL地址封装到axios.urls属性上

 

 

谢谢观看！
