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);

});
