如何在vue项目中嵌入jsp页面的方法(2种)

时间:2020-05-17 奔跑的痕迹人气:0

今日一个项目中一块功能模块是其他系统使用jsp已经开发好的页面，想着直接将其嵌入到当前的vue项目中节约开发成本；但是发现并非想象的那么简单

创建一个server.vue组件加载jsp页面

1 、第一种（使用 v-html进行jsp 渲染）

server.vue

<template>
 <div class="docker-server">
  <div v-html="pageContent"></div>
 </div>
</template>

<script type="text/ecmascript-6">
  export default {
    name: "server",
   data(){
     return{
      pageContent:'',
     }
   },
   created(){
      this.getDockerPage();
   },
   methods:{
    getDockerPage() {

     // $post为全局的axios post请求对象；dockerMange 为后端ip
     let url = `${api_config.dockerMange}/core/funcs/systemhttps://img.qb5200.com/download-x/docker/server/index.jsp`;
     this.$post(url).then(res => {
      console.log(res);
      this.pageContent = res.data;
     }).catch(err => {
      console.log(err)
     });
    }
   }
  }
</script>

<style scoped>

</style>

请求返回的jsp数据格式

后台返回的 index.jsp 内容如下：

<!DOCTYPE html>
<script type="text/javascript">
/** 常量定义 **/
var TDJSCONST = {
 YES: 1,
 NO: 0
};
/** 变量定义 **/
var contextPath = "https://img.qb5200.com/download-x/docker";
var imgPath = "https://img.qb5200.com/download-x/docker/core/styles/style1/img";
var ssoUrlGPower = "";
var limitUploadFiles = "jsp,java,jspx,exe"
var signFileServiceUrl = http://**/BjfaoWeb/TitleSign";
var isOnlineEval = "0";
var useSearchFunc = "1";
var maxUploadSize = 500;
var isDev = "0";
var ostheme = "1";
</script>

<html style="overflow: hidden;">
<head>
  <title>Docker容器服务器管理</title> <!-- http://** 我为保护服务ip 而手动更改了 -->
  <link rel="stylesheet" href="http://**https://img.qb5200.com/download-x/docker/core/styles/style1/css/views.css" rel="external nofollow" type="text/css"/>

  <script type="text/Javascript" src=http://**https://img.qb5200.com/download-x/docker/core/jshttps://img.qb5200.com/download-x/datastructs.js"></script>
  <script type="text/Javascript" src="http://**https://img.qb5200.com/download-x/docker/core/js/sys.js"></script>
  <script type="text/Javascript" src="http://**https://img.qb5200.com/download-x/docker/core/js/prototype.js"></script>
  <script type="text/Javascript" src="http://**https://img.qb5200.com/download-x/docker/core/js/smartclient.js"></script>
  <script type="text/Javascript" src="http://**https://img.qb5200.com/download-x/docker/core/js/cmp/tab.js"></script>
  <script type="text/javascript">
    function doInit() {
      var tabArray = [{
        title: "容器服务器管理",
        content: "",
        contentUrl: "http://**https://img.qb5200.com/download-x/docker/core/funcs/systemhttps://img.qb5200.com/download-x/docker/server/manage.jsp",
        imgUrl: "http://**" + imgPath + "/cmp/tab/sys_config.gif",
        useIframe: true
        },
        {
          title: "新增容器服务器",
          content: "",
          contentUrl: "http://**https://img.qb5200.com/download-x/docker/core/funcs/systemhttps://img.qb5200.com/download-x/docker/server/edit.jsp",
          imgUrl: "http://**" + imgPath + "/cmp/tab/sys_config.gif",
          useIframe: true
        }];
      buildTab(tabArray, 'contentDiv');
    }
  </script>
</head>
<body onload="doInit();">
<div id="contentDiv"></div>
</body>
</html>

页面显示如下：

因：jsp页面只是写了几个标签，其他数据都是通过外部js中的方法动态渲染出来的，然而使用v-html只是将jsp 页面加载到了当前页面上，但是没有将js 再次load进来；所以页面上就只有几个没有用的标签！最终确认这种方法不可行

2、第二种（使用 iframe 进行jsp嵌入）

修改后的 server.vue

<template>
 <div class="docker-server">
  <iframe name = "iframeChild" id = "iframeChild" v-bind:src="getPageUrl"
      width="100%" :height="iframeHeight"
      frameborder="0" scrolling="no" ref="iframeDom"
  ></iframe>
 </div>
</template>

<script type="text/ecmascript-6">
  export default {
    name: "server",
   data(){
     return{
      iframeHeight:500,
      getPageUrl:`${api_config.dockerMange}/core/funcs/systemhttps://img.qb5200.com/download-x/docker/server/index.jsp?MySessionId=${JSON.parse(sessionStorage.getItem("userInfo")).userToken}`
     }
   },
   mounted: function () {
    this.$nextTick(() => {
     if(this.$refs.iframeDom)
      this.iframeHeight = window.innerHeight - this.$refs.iframeDom.$el.offsetTop;
    })
   },
  }
</script>

<style scoped>

</style>

这次终于对了运行效果如下：

还是老式的方法过的奥，测试证明这种方式可行，完美解决问题嘿嘿。
