大多数excel表格的导出,直接一个a标签跳转就行了
但是为了安全考虑,有些公司前端需要用post方式获取后端返回的文件流,前端使用node将文件流转译后再导出
下面就是代码
exportBtn(){ //导出修改为读取二进制文件流 let parm = { report_type: this.sheetType, set_id: this.searchName, selectDate: selectDate, startTime: startTime, endTime: endTime, }; api_tws.excelReport(qs.stringify(parm)).then((res) => { if (res == "apiError") { this.buttonDisabledType = false; return; } const blob = new Blob([res]); const elink = document.createElement("a"); elink.download = `报表.xls`; elink.style.display = "none"; elink.href = URL.createObjectURL(blob); document.body.appendChild(elink); elink.click(); URL.revokeObjectURL(elink.href); // 释放URL 对象 document.body.removeChild(elink); this.buttonDisabledType = false; }); } //上面是方法,下面是定义的api请求 export async function excelReport(body) { const res = await axios({ method: "post", responseType: "blob", url: serverUrl + '/excelReport/export?' + body }); return res; }
