vuejs解决后端返回txt数据（后端返回oss富文本数据地址）

methods: {
    urlToBlob(url) {
      const that = this;
      const file_url = url || '';
      const xhr = new XMLHttpRequest();
      xhr.open('get', file_url, true);
      xhr.responseType = 'blob';
      // eslint-disable-next-line func-names
      xhr.onload = function () {
        if (this.status === 200) {
          const reader = new FileReader();
          // eslint-disable-next-line func-names
          reader.onload = function () {
            // eslint-disable-next-line func-names
            that.$nextTick(function () {
              this.textValue = reader.result;
            });
          };
          reader.readAsText(this.response);
        }
      };
      xhr.send();
    },

    // 获取详情页面数据
    async getDetailsData(id) {
      try {
        const result = await getDetails(id);
        if (result.txtUrl) {
          this.urlToBlob(result.txtUrl);
        }
        this.detailsData = result;
      } catch (err) {
        console.log(err);
      }
    }
  },
