文档流下载

Excel、PPT、Word等文档流下载

以下是一个简单的下载示例，具体配置根据使用的请求工具有所差异

const downloadExcel = async () => {
  const typeMap = {
    "application/vnd.ms-excel": "xls",
    "application/msword": "doc",
    "application/vnd.ms-powerpoint": "ppt",
    // ...
  };
  // 获取Excel文件，设置响应类型为arraybuffer（二进制）或者blob
  const res = await getExcel({
    url: "文件路径",
    method: "get",
    responseType: "arraybuffer", // blob
  });
  // 设置文件属性
  const fileType = [
    `${res.headers["content-type"]};charset=utf-8`,
    // ...
  ];
  // 获取文件名，也可以自己设置，但必须加上正确的后缀
  //如果从响应头获取要是返回的乱码则需要后端配合进行解码处理
  const contentDisposition = res.headers["content-disposition"];
  const matches = contentDisposition.match(/filename=([^;]+)/);
  const filename = matches && matches.length > 1 ? matches[1] : "";

  const blob = new Blob([res], { type: fileType }); // 创建blob对象
  const downloadElement = document.createElement("a"); // 创建a标签
  const href = window.URL.createObjectURL(blob);
  downloadElement.style.display = "none";
  downloadElement.href = href;
  downloadElement.download = filename; // 设置下载文件名
  document.body.appendChild(downloadElement); // 将a标签追加到body中
  downloadElement.click(); // 点击下载
  document.body.removeChild(downloadElement); // 下载完成移除元素
  window.URL.revokeObjectURL(href); // 释放掉blob对象
};
