Json格式数据展示
vue的jsonViewer组件也很好用，在网上看到有大神自己写的组件（递归调用），觉得很好，稍作修改，记录一下
JSON.stringify(obj, null, 4)
可以美化json数据的显示

<span class="light">要高亮的内容</span> 在json数据中，如果有需要高亮的内容，用以上标签包起来（这个要处理数据实现了，组件里高亮样式可以根据需要自己修改）
<template> <div class="bgView"> <div :class="['json-view', length ? 'closeable' : '']" :style="'font-size:' + fontSize+'px'"> <span @click="toggleClose" :class="['angle', innerclosed ? 'closed' : '']" v-if="length"></span> <div class="content-wrap"> <p class="first-line"> <span v-if="jsonKey" class="json-key">"{{jsonKey}}": </span> <span v-if="length" @click="toggleClose" style="cursor: pointer;"> {{prefix}} {{innerclosed ? ('... ' + subfix) : ''}}  </span> <span v-if="!length">{{isArray ? '[]' : '{}'}}</span> </p> <div v-if="!innerclosed && length" class="json-body"> <template v-for="(item, index) in items"> <json-view v-if="item.isJSON" :closed="closed" :key="index" :json="item.value" :jsonKey="item.key" :depth="depth+1" :expandDepth="expandDepth" :isLast="index === items.length - 1"></json-view> <p v-else class="json-item" :key="index"> <span class="json-key"> {{(isArray ? '' : '"' + item.key + '":')}} </span> <span class="json-value" v-html="item.value + (index === items.length - 1 ? '' : ',')"/> </p> </template>  </div> <p v-if="!innerclosed && length" class="last-line"> <span>{{subfix}}</span> </p> </div> </div> </div></template>

vue解析json数据
在前端接授到json后，使用JSON.parse(jsonObject)就可以解析！（jsonObject为json对象）
