export function downloadKnowledage(parameter) {return axios({url: '/knowledage/download',method: 'GET',params: parameter,responseType: 'blob'})
}

添加 responseType: 'blob’解决以下乱码现象

使用触发a标签下载文件

downloadKnowledage(data).then((res) => {let link = document.createElement("a");link.href = window.URL.createObjectURL(new Blob([res.data], {type: "application/octet-stream;charset=UTF-8",}));link.setAttribute("download", file_name);document.body.appendChild(link);link.click();link.remove();});
