vue通过Blob实现下载文件

需求是这样的......

具体实现,前端拿到后端返回回来的数据,然后通过Blob实现下载,文件内容样式啥的都是后端写的

script代码:

这里的data就是后端返回回来的数据,此方法兼容IE

download(data) {
      if (!data) {
        return;
      }
      let blob = new Blob([data], {
        type:
          "application/vnd.openxmlformats-officedocument.wordprocessingml.document;charset=utf-8"
      });
      let url = window.URL.createObjectURL(blob);
      let fileName = this.data.plan_no + "出团通知单.docx";
      if ("download" in document.createElement("a")) {
        const a = document.createElement("a");
        a.href = url;
        a.download = fileName;
        a.style.display = "none";
        document.body.appendChild(a);
        a.click();
        URL.revokeObjectURL(a.href);
        document.body.removeChild(a);
      } else {
        navigator.msSaveBlob(blob, fileName);
      }
    }
