vue 格式化显示对比json串

1.使用插件 npm install vue-code-diff
2.引入插件

import CodeDiff from "vue-code-diff";
export default {
  components: { CodeDiff },
  data() {
    return {
      oldStr: "",
      newStr: ""
    };
  },

3.template使用

<div>
      <code-diff
        :old-string="oldStr"
        :new-string="newStr"
        outputFormat="side-by-side"
        :context="10"
      >
      </code-diff>
    </div>

4.重点来了，格式化

this.oldStr = JSON.stringify(response.data,null,4);
this.newStr = JSON.stringify(response.data.data,null,4);

5.效果显示

6.整体代码
