表单导入文件和数据提示跨域, 以及提示'请先登录'

表单大致代码如下

<template>
    <div class="centered-container">
      <el-dialog v-model="isOpen" title="发起转让">
        <el-form :model="form" label-width="160px" >

          <el-form-item label="文件">
            <el-upload ref="upload" :action="transferGoods" :auto-upload="false" :data="form" :on-success="onSuccess">
              <el-button type="primary">选择文件</el-button>
            </el-upload>
          </el-form-item>

          <el-form-item label="文本框导入">
            <el-input v-model="form.text" type="textarea" class="el-input" placeholder="一行一个" />
          </el-form-item>
        </el-form>

        <span class="dialog-footer">
          <el-button type="warning" @click="submitUpload">开始导入</el-button>
          <el-button>清空</el-button>
        </span>


    </el-dialog>
    </div>
  </template>
