1.导出

 try {let response = null;response = await exportCheckAmendment({type: 2,reportId: row.id});if (response.size < 100) return ElMessage.warning("暂无修订件");// 处理请求返回的文件流const content = response as BlobPart;const blob = new Blob([content], {type: "application/msword;charset=UTF-8"});const extension = row.fileReportName.slice(row.fileReportName.lastIndexOf("."));const fileName = `${row.fileReportName}（修订件）${extension}`;const elink = document.createElement("a");elink.download = fileName;elink.style.display = "none";elink.href = URL.createObjectURL(blob);document.body.appendChild(elink);elink.click();URL.revokeObjectURL(elink.href);document.body.removeChild(elink);} finally {// loading.value = false;}

2.下载（不携带token）

  const link = document.createElement("a");link.href = url;link.setAttribute("download", "");document.body.appendChild(link);link.click();document.body.removeChild(link);

携带token

 //这是请求的地址 （自定义）const param = {};const _herf = url;// 这是请求头中需要的token （自定义）const userInfo = JSON.parse(window.sessionStorage.getItem("user-info"));const token = userInfo.refreshToken;axios.post(`${_herf}`, param, {responseType: "blob",headers: {token,// 这是格式，看后段要不要你传 （自定义）ContentType: "application/json"}}).then(res => {const blob = res.data;const reader = new FileReader();reader.readAsDataURL(blob);reader.onload = e => {const a = document.createElement("a");a.download = "xlsName";a.href = e.target.result;document.body.appendChild(a);a.click();document.body.removeChild(a);};}).catch(err => {console.log(err.message);});

3.预览

    const response = await getOverdueReportReview(row.id);if (!response) {loading.value = false;return;}const url = import.meta.env.VITE_PROXY_MONITOR;// 本地预览// window.open("http://localhost:8848/#/viewReport?id=" + row.id, "_blank");//线上环境window.open(url.replace(new RegExp(`/api`, "g"), "") +":8000/jkzx_dev/#/viewReport?id=" +row.id,"_blank");
