antd pro table中的文件上传

概述

项目中经常会遇到在表格中展示图片的需求(比如展示用户信息时, 有一列是用户的头像).

antd pro table 的功能很强大, 对于常规的信息展示只需参照示例配置 column 就可以了. 但是对于文件(比如图片) 在表格中的展示, 介绍并不多.

下面通过示例来演示 antd pro table 中图片的上传和展示.

示例代码

前端主要包含如下 2 部分:

  1. 列表页面: 通过 antd pro table 显示数据信息
  2. 表单页面: 新建/修改数据的页面, 上传图片的功能就在其中

一个模块主要包含如下几个文件:

  1. teacher.jsx: 显示数据列表信息
  2. teacher-form.jsx: 用于添加/修改数据
  3. model.js: list.jsx 和 form.jsx 之间共享数据
  4. service.js: 访问后端的 API

下面的例子是实际项目中的一个简单的模块, 完成教师信息的 CURD, 教师的头像是图片文件

service.js 中的请求是 graphql api

总结

  1. 这个模块的 增和改 用的同一个页面, 因为是弹出的 modal, 所有实际的提交功能是在 teacher.jsx 中完成的

  2. antd upload 组件的 外围 FormItem 需要加上如下属性(valuePropName 和 getValueFromEvent):

    1  <FormItem 2    label="用户头像" 3    name="avatarFile" 4    valuePropName="fileList" 5    getValueFromEvent={normFile} 6  > 7      <Upload /> 8  </FormItem> 
  3. antd upload 组件虽然有默认的上传事件, 但是如果自定义上传的事件, 可以更方便的和自己的后端 API 进行对接

     1  const uploadAvatar = async ({ onSuccess, onError, file }) => {  2    const response = await upload('avatar', file);  3    try {  4      const {  5        code,  6        data: { fid },  7      } = response;  8    9      onSuccess(response, file); 10   11      dispatch({ type: 'teacher/setAvatarFid', payload: fid }); 12    } catch (e) { 13      onError(e); 14    } 15  };
