1、下载csv/txt时
此时无须修改接口的响应格式

let filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
let matches = filenameRegex.exec(data.headers['content-disposition']);
let blob = new Blob(['\uFEFF' + data.data], {//目前只有csv格式type: 'text/csv;charset=utf-8'
})
var downloadElement = document.createElement('a');
var href = window.URL.createObjectURL(blob);
downloadElement.href = href;
downloadElement.download = matches[1].substring(0, matches[1].lastIndexOf('.'));
document.body.appendChild(downloadElement); 
downloadElement.click(); //注销掉
window.URL.revokeObjectURL(href); //清除生成的链接，会占用一些东西，不知道啥，反正运行慢点

2、下载Excel时，需要修改一下接口的响应格式为blob

axios({method: "POST",url: constants.url.QUERY_DESCRIBE_TEST_REPORT_DOWNLOAD,responseType: "blob",//FIXME 很重要timeout: 60000,data: {TestTaskId,},}).then((response) => {console.log("response", response);if (!response || !response.data) {self.$message({type: "error",message: "导出失败！",});return;}let filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;let matches = filenameRegex.exec(response.headers["content-disposition"]);let blob = new Blob([response.data]);let downloadFilename = matches[1];if (window.navigator && window.navigator.msSaveOrOpenBlob) {//兼容ie浏览器window.navigator.msSaveOrOpenBlob(blob, downloadFilename);} else {//谷歌,火狐等浏览器let url = window.URL.createObjectURL(blob);let downloadElement = document.createElement("a");downloadElement.style.display = "none";downloadElement.href = url;downloadElement.download = downloadFilename;document.body.appendChild(downloadElement);downloadElement.click();document.body.removeChild(downloadElement);window.URL.revokeObjectURL(url);}}).catch((err) => {this.$message.error(err);});
