前端将后端api返回的流文件转成excel:
downloadExcel(res){
const file = res.headers["content-disposition"].split(";")[1];
const fileName = decodeURI(file.split("=")[1]);
let a = document.createElement("a");
let blob = new Blob([res.data], { type: "application/vnd.ms-excel" });
let objectUrl = URL.createObjectURL(blob);
a.setAttribute("href", objectUrl);
a.setAttribute("download", fileName);
a.click();
},
调用后端api的responseType: "arraybuffer"，这个解决文件打开乱码问题，以aixos为例：
export function exportMergeConflicts(params) {
return request({
url: '/cms/mergeConflict/exportMergeConflicts',
responseType: "arraybuffer",
method: 'post',
data: params
})
}
exportMergeConflicts(params).then(res => {
this.downloadExcel(res)
})
