el-upload上传多个文件，一次请求，Django接收

1、:file-list="fileList"  :on-change="handleChange" 将文件赋值到fileList

2、 :auto-upload="false"  手动触发上传 写个按钮点击执行这个 this.$refs.upload.submit();

3、自己写上传，不会再触发上传成功或失败回调

4、 request.FILES.getlist('file') 获取上传的多个文件，循环读取写入文件中

 <el-upload
     class="upload-demo"
     ref="upload"
     action=""
     :on-change="handleChange"
     :file-list="fileList"
     :auto-upload="false"

     >
     <el-button slot="trigger" size="small" type="primary">选取文件</el-button>
     <el-button style="margin-left: 10px;" size="small" type="success" @click="submitUpload">上传到服务器</el-button>
     <div slot="tip" class="el-upload__tip">只能上传jmx/txt文件</div>
</el-upload>

<script>
    import axios from 'axios'
    export default{
        name:"StressTest",
            data() {
                     return {
                     fileList: []
                     }
            },
            components:{

            },
          
            methods:{
              handleChange(file, fileList) {
                console.log(file, fileList);
                this.fileList = fileList
                console.log('=====',this.fileList)
              },
              submitUpload() {  //上传
                    let formData = new FormData();  //  用FormData存放上传文件
                    this.fileList.forEach(file => {
                        formData.append('file', file.raw)
                    })
                    this.fileList = []
                    console.log('========',formData)
                    this.$axios.post('/uploadfile/', formData).then((res) => {
                        //手动上传无法触发成功或失败的钩子函数，因此这里手动调用
                    　　console.log('========','success')
                     
                       this.handleUploadSuccess()
                    }, (err) => {
                    　
                       this.handleUploadError()
                    })
                },


               handleUploadSuccess(){
                this.$refs.upload.clearFiles()
                alert('上传成功')
               
                },
              handleUploadError(){
                 alert('上传失败')
             }

           // methods关闭
            }
    }
</script>

 下面试着还是上次触发多次请求呢

<el-upload
    class="upload-demo"
    ref="upload"
    action=""
    :on-change="handleChange"
    :on-success="handleUploadSuccess"
    :on-error="handleUploadError"
    :file-list="fileList"
    :auto-upload="false"
    :http-request="uploadFile"
    >
    <el-button slot="trigger" size="small" type="primary">选取文件</el-button>
    <el-button style="margin-left: 10px;" size="small" type="success" @click="submitUpload">上传到服务器</el-button>
    <div slot="tip" class="el-upload__tip">只能上传jmx/txt文件</div>
</el-upload>


<script>
    import axios from 'axios'
    export default{
        name:"StressTest",
            data() {
                     return {
                     fileList: []
                    
                     }
            },
            components:{

            },
           
            methods:{

              handleChange(file, fileList) {

                this.fileList = fileList
                console.log('=====',this.fileList)
              },
              uploadFile(file) {  //上传
                    let formData = new FormData();  //  用FormData存放上传文件

                    　　console.log('========','success')
                       file.onSuccess(res)
                    }, (err) => {
                    　　file.onError(err)
                    })
