使用h5自带的input type=file时,使用change触发上传事件
<input class="exportss" type="file" id="fileExport" @change="handleFileChange" ref="inputer">
const inputDOM = this.$refs.inputer
this.file = inputDOM.files[0] // 通过DOM取文件数据
let size = Math.floor(this.file.size / 1024)
this.formData = new FormData() // new一个formData事件
this.formData.append('file',data.file)
this.formData.append('xxx', xxx)
this.formData.append('yyy', yyy)
inputDatas(this.formData).then(response => {
})
或者使用element的el-uploader
<el-upload
ref="upload"
:data="inputdata"
class="upload-demo"
:action="uploadUrl"
:show-file-list="false"
:on-preview="onpreview"
:before-upload="beforeAvatarUpload"
:on-error="handleError"
:on-success="handleSuccess"
:file-list="fileList">
<el-button :loading="loadings.isInport" class="btn-special blue-btn" icon="el-icon-upload" size="mini" type="primary">导入</el-button>
</el-upload>
action为上传文件的地址,可手动拼接
若需要token验证,可添加:header="header"
headers: {
Authorization: Cookies.get('token')
//从cookie里获取token,并赋值 Authorization ,而不是token
}
