vue 接口返回流 直接下载下来

    downloadBlob(response) {
      // response 是接口返回流
      let blob = new Blob([response], {
        type: "application/msword;charset=UTF-8",
      });
      // let blob = new Blob([response], { type: 'application/pdf;chartset=UTF-8' })
      const url = window.URL.createObjectURL(blob);
      const link = document.createElement("a");
      link.style.display = "none";
      link.href = url;
      console.log("link.href", link.href);
      link.download = `附件`;
      document.body.appendChild(link);
      link.click();
      window.URL.revokeObjectURL(link.href); //释放url
      document.body.removeChild(link); //释放标签
    },

new Blob([response], {type: "application/msword;charset=UTF-8",});
