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);
});
