使用 http-request
覆盖默认的上传行为,可以自定义上传的实现
利用 before-upload
上传文件之前的钩子,参数为上传的文件,若返回 false
或者返回 Promise
且被 reject
,则停止上传
template 部分
<el-upload
class="pad"
ref="upload"
action="action"
:http-request="uploadBpmn"
:before-upload="beforeUpload">
<el-button size="medium" type="primary" class="el-icon-upload"> 部署流程定义</el-button>
</el-upload>
js 部分
beforeUpload (file) { // 上传文件之前钩子
const type = file.name.split('.')[1]
if (type !== 'bpmn') {
this.$message({ type: 'error', message: '只支持bpmn文件格式!' })
return false
}
},
uploadBpmn (param) { // 部署流程定义(点击按钮,上传bpmn文件,上传成功后部署,然后重新加载列表)
const formData = new FormData()
formData.append('processDefinition', param.file) // 传入bpmn文件
this.$API({
name: 'deploy',
data: formData,
headers: {'Content-Type': 'multipart/form-data'}
}).then(res => {
if (res.data.code == 0) {
this.$message({ type: 'success', message: res.data.msg })
} else {
this.$message({ type: 'error', message: res.data.msg })
}
}).catch(error => {
this.$message({ type: 'error', message: error })
}).finally(() => {
this.getList()
})
},
如果不想上传成功后显示上传文件列表,可以隐藏掉文件列表
可以在组件中设置 :show-file-list="false"
或者
::v-deep .el-upload-list {
display: none !important;
}
<template>
<div class="app-upload">
<div class="upload-title">上传文件</div>
<el-upload
class="upload-demo"
ref="uploadBox"
drag
action="action"
:before-upload="beforeUpload"
:http-request="upload"
:auto-upload="false"
multiple>
<i class="el-icon-upload"></i>
<div class="el-upload__text">将文件拖到此处,或<em>点击上传</em></div>
</el-upload>
<div class="upload-btn">
<el-button type="primary" @click="sure" :loading="loading">确 定</el-button>
</div>
</div>
</template>
<script>
const formData = new FormData()
export default {
data () {
return {
loading: false
}
},
methods: {
beforeUpload (file) { // 上传文件之前钩子
formData.append('files', file)
},
upload () {
this.loading = true
this.$API({
name: 'UploadResource',
data: formData,
params: {
path: this.$route.query.path
},
requireAuth: true
}).then (res => {
if (res.data.code === 200) {
this.$notify.success(res.data.msg)
} else {
this.$notify.error(res.data.msg)
}
}).catch(error => {
this.$notify.error(error)
}).finally(() => {
this.loading = false
this.reset()
})
},
sure () {
this.$refs.uploadBox.submit()
},
}
}
</script>
只需要为 input
输入框设置 webkitdirectory
属性
mounted() {
if (this.$route.query.type === 'folder') {
this.$nextTick(() => {
document.querySelector('.el-upload__input').webkitdirectory = true
})
}
},
