              :action="fileAPI"
              :on-preview="handlePreview"
              :on-remove="handleRemove"

              list-type="picture"
              :limit="1"
            >
              <el-button size="small" type="primary">点击上传</el-button>
              <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div>
            </el-upload>
          </el-form-item>

修改回显的时候判断修改对象给file-list添加一个成员就可以了

修改和添加直接根据修改提交对象的内容就可以了
