distinguish whether the file stream returned by the back end or directly trigger the link to download?
if the link download is triggered directly, it is very simple
if it is a file stream, the front end needs to do another processing before downloading
my sample code is axios, for your reference
1 triggers the download API. To set responseType = 'blob'
in axios, refer to the official document https://github.com/axios/axios
2 write a function that accepts the file stream
// blob
// blob fileName
function downFiles(blob, fileName) {
let link = document.createElement('a')
link.href = window.URL.createObjectURL(blob)
link.download = fileName
link.click()
window.URL.revokeObjectURL(link.href)
}
3 there is also some processing to be done in the callback function that sends the request, for example, I want to trigger the xx/down interface
api("down", formData, "post", "blob").then(function(res) {
let blob = new Blob([res.data], {
type: '*'
})
let fileName = ''
_this.$tool.downFiles(blob, fileName)
_this.isDown = false
}) https://www.cnblogs.com/webbe.
