问题：

解决问题：

重点是：加入action="#"和:http-request="uploadHttpRequest"

<el-upload
  v-loading="isLoading"
  ref="upload"
  v-model="fileList"
  :multiple="multiple"
   action="#"
  :limit="max"
  :http-request="uploadHttpRequest" 
  accept="image/png, image/jpeg, image/gif,video/mp4,video/avi,video/mpeg,video/quicktime,video/webm,video/ogg,video/3gpp-tts,video/3gpp2-tts,"
   :auto-upload="autoUpload"
   :show-file-list="showFileList"
   :drag="drag"
   :on-exceed="handleExceed"
   :before-upload="handleUpload"
>

所以只要加上 :http-request="uploadHttpRequest"就能自定义上传，然后调用上传接口，进行上传操作。
