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); });另
