1、接口返回的是文件流
function download_excel (data) {
const aLink = document.createElement('a')
const blob = new Blob([res], { type: 'application/vnd.ms-excel,charset=utf-8' })
aLink.href = URL.createObjectURL(blob)
aLink.setAttribute('download', 'example' + '.xlsx')
aLink.click()
}
2、接口返回的是base64
// 方法1
function download_excel (data) {
const sliceSize = 512;
const byteCharacters = atob(data);
const byteArrays = [];
for (let offset = 0; offset < byteCharacters.length; offset += sliceSize) {
const slice = byteCharacters.slice(offset, offset + sliceSize);
const byteNumbers = new Array(slice.length);
for (let i = 0; i < slice.length; i++) {
byteNumbers[i] = slice.charCodeAt(i);
}
const byteArray = new Uint8Array(byteNumbers);
byteArrays.push(byteArray);
}
const file = new File(byteArrays, 'example.xls', {type: 'application/vnd.ms-excel,charset=utf-8'});
const aLink = document.createElement('a')
aLink.href = URL.createObjectURL(file)
aLink.setAttribute('download', 'example' + '.xls')
aLink.click()
}
// 方法2
unction download_excel (data) {
const raw = atob(dat)
const uInt8Array = new Uint8Array(raw.length)
for (let i = 0; i < raw.length; i++) {
uInt8Array[i] = raw.charCodeAt(i)
}
const aLink = document.createElement('a')
const blob = new Blob([uInt8Array], { type: 'application/vnd.ms-excel,charset=utf-8' })
aLink.href = URL.createObjectURL(blob)
aLink.setAttribute('download', 'example' + '.xlsx')
aLink.click()
}
