vue el-upload 手动上传问题

vue el-upload 手动上传 代码如下

打印

请求 表单是Object

前端不太懂，求帮忙看下，后台要接收binary

可以参考下

const { uploadFiles } = this.$refs.upload;
let formData = new FormData();
for (let i = 0; i < uploadFiles.length; i++) {
      formData.append("file", uploadFiles[i].raw);
   }
formData.append("picType", "01");
     
this.btnLoading = true; //按钮状态
   axios({
       headers: {
         "Content-Type": "multipart/form-data"
       },
       method: "post",
       url: uploadPicXj,
       data: formData
     }).then(res => {

formData直接console.log(formData)看不到数据；需要遍历输出formData.forEach(value => console.log(value)); 还有你的问题是没成功哪里出来了问题？
