关于构建umi+dva+ant react项目附源码

刚刚入门react，通过视频学习，做一个简单的react表格功能实现。功能满足对表格数据进行增删改，数据来源于后端接口。交互也与后端接口进行！

话不多说，直接看效果！

接口设置了30%的概率报错，出现错误多刷新几次。

这是后端接口地址 https://public-api-v1.aspirantzhang.com/

浏览器可以直接看到接口数据

项目的搭建是参照于umi官网的快速上手进行搭建的，想要试试的小伙伴可以先将项目搭建起来！https://umijs.org/zh-CN/docs/getting-started

我们的项目主要集中在page下的users文件夹中的内容！

在page下新建uses文件夹

新建这几个文件

我们在components文件夹下放的文件的组件，UserModal，为弹出框组件

import React,{useEffect,FC} from "react";
import {Modal, Button ,Form,Input} from 'antd';
import {SingleUserType,FormValues} from '../data'


interface UserModalProps{
    visible:boolean;
    record:SingleUserType|undefined
    closeHandeler:()=>void
    onFinish:(values:FormValues)=>void
}
const UserModal :FC<UserModalProps> = (props)=>{
    const[form]=Form.useForm();
    const {visible,record,closeHandeler,onFinish} = props
    // useEffect(参数1，参数2)  当参数2发生改变时，执行参数1     参数1为函数，参数2为数组
    useEffect(()=>{
       
        if(record==undefined){
            form.resetFields();
        }
        else{
            form.setFieldsValue(record);
        }
    },[visible])

    const onOk=()=>{
        form.submit()
    }
        
      const onFinishFailed = () => {
        console.log('Submit failed!');
      };

    return(
        <div>
             <Modal title="基本信息"
              visible={visible}
               onOk={onOk}
               onCancel={closeHandeler}
               forceRender>
                   
          <Form
            name="basic"
            form={form} 
            onFinish={onFinish}
            onFinishFailed={onFinishFailed}
            >
            <Form.Item
                label="姓名"
                name="name"
                rules={[
                {
                    required: true,
                    message: 'Please input your name!',
                },
                ]}
            >
                <Input />
            </Form.Item>

            <Form.Item label="邮箱" name="email">
                <Input />
            </Form.Item>
            <Form.Item label="创建时间" name="create_time">
                <Input />
            </Form.Item>
            <Form.Item label="状态" name="status">
                <Input />
            </Form.Item>

          

            
    </Form>
        </Modal>
        </div>
    )
}
export default UserModal

在users文件夹下index为主页面，data.a为数据类型，model为模块文件，service为交互后端文件
