public submitUpload() {
//@ts-ignore
let {
uploadFiles, action, data} = this.$refs.uploadFile;
//@ts-ignore
this.uploadFiles({
uploadFiles,
data,
action,
success: (response:any) => {
//@ts-ignore
this.$refs.uploadFile.clearFiles();
},
error: (error:any) => {
console.log('失败了', error)
}
})
}
public uploadFiles({
uploadFiles, headers, data, action, success, error}) {
let form = new FormData()
// 文件对象
//@ts-ignore
uploadFiles.map(file => form.append("files", file.raw))
// 附件参数
for (let key in data) {
form.append(key, data[key])
}
let xhr = new XMLHttpRequest()
// 异步请求
xhr.open("post", action, true)
// 设置请求头
xhr.setRequestHeader("Authorization", this.$store.state.user.userInfo.token);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4){
if ((xhr.status >= 200 && xhr.status < 300) || xhr.status == 304){
success && success(xhr.responseText)
} else {
error && error(xhr.status)
}
}
}
xhr.send(form)
