之前有一篇写的如何同时传递form表单及upload组件文件，如果有多个upload文件该如何传递呢

上代码

html

 <el-form-item prop="expName" label="">
 <el-input v-model="newform.expName" placeholder="" style="width:75%">

 <el-form-item label="" prop="expvmInstruction">
 <el-upload

 <div slot="tip" class="el-upload__tip">实验视频上传，只能传(.mp4)文件</div>
 </el-upload>
 </el-form-item>
 <el-form-item style="text-align:center">
 <el-button type="primary" @click="newSubmitForm()" class="yes-btn">

 </el-form-item>
 </el-form>

js

data () {
 return {
　　　 upload_url: 'aaa', // 随便填一个，但一定要有
　　 uploadForm: new FormData(), // 一个formdata
 rules: {}, // 用到的规则
 newform: {
 expName: '',
 groupName: '',
 expSn: '',
 subGroupName: '',
 expvmDifficulty: 1
 }
 }
 }

methods

newSubmitForm () {
 this.$refs['newform'].validate((valid) => {
 if (valid) {
 this.uploadForm.append('expName', this.newform.expName)
 this.uploadForm.append('expSn', this.newform.expSn)
 this.uploadForm.append('groupId', this.newgroupId)
 this.uploadForm.append('subGroupId', this.newsubgroupId)
 this.uploadForm.append('expvmDifficulty', this.newform.expvmDifficulty)
 
 newExp(this.uploadForm).then(res => {
 if (res.code === 400) {
 this.$message.error(res.error)
 } else if (res.code === 200) {
 this.$message.success('上传成功！')
 
 }
 })
 this.$refs.uploadhtml.submit() // 提交时触发了before-upload函数
 this.$refs.uploadfile.submit()
 this.$refs.uploadvideo.submit()
 
 } else {
 console.log('error submit!!')
 return false
 }
 })
 },
 newHtml (file) { // before-upload
 this.uploadForm.append('html', file)
 return false
 },
 newFiles (file) {
 this.uploadForm.append('file[]', file)
 return false
 },
 newVideo (file) {
 this.uploadForm.append('video', file)
 return false
 }
newExp函数是作为一个前后端交互的函数
export function newExp (data) {
 return axios({
 method: 'post', // 方式一定是post
 url: '你的后台接收函数路径',
 timeout: 20000,
 data: data // 参数需要是单一的formData形式
 })
}

PHP代码，后台接收

public function newExp() {
 $param = $this->request->post(); // 获取页面表单传值
 $files = $this->request->file(); // 接收到的文件
 }

注意

this.uploadForm.append('file[]', file)

这里是接收多文件一定要是数组形式的file[]
