Vue3使用ElementPlus中的el-upload手动上传并调用上传接口

前端代码

	   <div class="upload-div">
          <el-upload
            v-model:file-list="form.fileImageList"
            ref="uploadRef"
            capture="false"
            action="#"
            accept="image/*"
            list-type="picture-card"
            :on-change="handleChange"
            :auto-upload="false"
            :on-preview="handlePictureCardPreview"
            :on-remove="handleRemove"
            :multiple="true"
          >
            <el-icon>
              <Plus/>
            </el-icon>
          </el-upload>

          <el-dialog v-model="dialogVisible" class="image-dialog">
            <img style="width: 100%;height: 100%
