如果后端明确告诉你返回的是base64,那请求头就不用带responseType: “blob”,和普通的接口一样发送就行
await materialsFile({ id: proxy.$route.query.id }).then((res) => {if (res) {const raw = window.atob(res.data);const rawLength = raw.length;const uInt8Array = new Uint8Array(rawLength);for (let i = 0; i < rawLength; ++i) {uInt8Array[i] = raw.charCodeAt(i);}const link = document.createElement("a");let blob = new Blob([uInt8Array]);link.style.display = "none";link.href = URL.createObjectURL(blob);link.setAttribute("download",`${userForm.value.name}-${userForm.value.phone}.zip`);document.body.appendChild(link);link.click();document.body.removeChild(link);window.URL.revokeObjectURL(link.href);}});
