使用 onUploadProgress 实现
let self = this
this.axios.put(this.uploadUrl, this.files[0], {
headers: {
'Content-Type': 'multipart/form-data'
},
transformRequest: [function (data) {
return data
}],
onUploadProgress: progressEvent => {
let complete = (progressEvent.loaded / progressEvent.total * 100 | 0) + '%'
self.uploadMessage = '上传 ' + complete
}
})
.then((response) => {
if (response.status === 200) {
self.uploadMessage = '上传成功！'
}
})
