整体页面效果

项目技术点

• antd组件库，@ant-design/icons antd的图标库
• axios 接口请求，拦截器配置
• node-sass sass-loader css样式的一个嵌套
• react-router-dom react路由使用
• react-redux redux
• hooks：大多数我们用的是函数组件，函数组件没有state属性，所以我们使用hooks来初始化数据，并且函数组件没有生命周期

拦截器的配置

由于我们登录成功之后，需要我们获取到token令牌之后，我们才能获取到数据，如果每个页面都需要获取一次token，代码比较啰嗦，所以我们配置了一个拦截器

需要授权的 API ，必须在请求头中使用 Authorization 字段提供 token 令牌

//配置拦截器
import axios from "axios";
//2. 创建对象
const Server = axios.create({
    baseURL:"http://api.xiaohuihui0728.cn:8888/api/private/v1/",//基地址
    timeout:5000,
})
//3. 请求拦截器
Server.interceptors.request.use((config)=>{
    //前置拦截器请求发送出去之前触发
    console.log(config);
    //增加一个token值
    let token = sessionStorage.getItem("token");
    config.headers["Authorization"] = token; 
    return config;
},(err)=>Promise.reject(err));
//4. 响应拦截器
Server.interceptors.response.use((response)=>{
    //请求成功，服务端返回数据到客户端之前触发
    return response.data;
},(err)=>Promise.reject(err))
//5.抛出Serve对象的内容
export default Server;

主页面

我们的数据写在columns里面，在里面的dataIndex绑定我们获取到的数据

  const columns = [
        {
            title: '商品名称',
            dataIndex: 'goods_name',
            key: 'username',
        },
        {
            title: '商品价格',
            dataIndex: 'goods_price',
            key: 'email',
        },
        {
            title: '商品重量',
            dataIndex: 'goods_weight',
            key: 'mobile',
        },
        {
            title: '创建时间',
            dataIndex: 'goods_state',
            key: 'role_name',
        },
        {
            title: '操作',
            key: 'action',
            render: (_, record) => {
                return (
                    <>
                        <Button type="primary" size="small" onClick={() => { showedit(record.goods_id) }}> <EditOutlined /> </Button> &nbsp;
                        <Button type="primary" size="small" danger onClick={() => { delGoods(record.goods_id) }} > <DeleteOutlined /> </Button> &nbsp;
                    </>
                )
            }
        }
    ];
    const [userData, setUserData] = useState([])
 // 初始化数据 
    useEffect(() => {
        getUserData()
        setPage(1)
    }, [search, page, pageSize])
 // 初始化请求数据 用户
    const getUserData = async () => {
        console.log(pageSize);
        console.log(search);
        console.log(page);
        let { data } = await axios.get(`goods?pagenum=${page}&query=${search}&pagesize=${pageSize}`)
        console.log(data.goods);
        if (data) {
            setTotal(data.total);
            setUserData(data.goods);
        }
    }
 <Table pagination={false} bordered dataSource={userData} columns={columns} rowKey={(record) => record.goods_id} />

添加商品

添加弹出对话框，添加里面有一个上传图片，我们上传的图片有一个单独的添加接口，所以我们使用action属性绑定我们要上传的路径，headres获取token，使用onChange获取图片上传的路径，然后在我们点击提交form表单数据时把图片临时地址添加成功

    // 添加弹窗状态 
    const [addIsModalVisible, setAddIsModalVisible] = useState(false);
    // 存图片
    let [img,setimg] = useState("");
  // 添加取消 
    const addHandleCancel = () => {
        setAddIsModalVisible(false);
    };
//获取token
   let token = sessionStorage.getItem("token");
    // 添加商品
    const onAdd = async (value)=>{
        console.log(value);
        let pics = [{pic:img}];
        let data= await axios.post("goods",{...value,pics})
        setAddIsModalVisible(false);
        getUserData()
    }
//图片上传
    const success = (info)=>{
        if(info.file.status==="done"){
            console.log(info.file.response.data.tmp_path);
            setimg(info.file.response.data.tmp_path)
        } 
    }          
 <Modal title="商品添加" visible={addIsModalVisible} footer={null} ref={addFormRef}>
                <Form
                    name="basic"
                    labelCol={{ span: 4 }}
                    wrapperCol={{ span: 16 }}
                    initialValues={{ remember: true }}
                    onFinish={onAdd}
                    onFinishFailed={onFinishFailed}
                    autoComplete="off"
                >
                    <Form.Item
                        label="商品名称"
                        name="goods_name"
                        rules={[{ required: true, message: '请输入商品名称' }]}
                    >
                        <Input />
                    </Form.Item>
                    <Form.Item
                        label="商品价格"
                        name="goods_price"
                        rules={[{ required: true, message: '请输入商品价格' }]}
                    >
                        <Input />

                        name="goods_number"
                        rules={[{ required: true, message: '请输入商品数量' }]}
                    >
                        <Input />
                    </Form.Item>
                    <Form.Item
                        label="商品重量"
                        name="goods_weight"
                        rules={[{ required: true, message: '请输入商品重量' }]}
                    >
                        <Input />
                    </Form.Item>
                    <Form.Item
                        label="商品图片"
                        name="pics"
                    >
                        <Upload {...props} action='http://api.xiaohuihui0728.cn:8888/api/private/v1/upload'
                         headers={{"Authorization":token}} onChange={success} listType='picture'>
                            <Button type='primary'>上传图片</Button>
                        </Upload>
                    </Form.Item>
                    <Form.Item wrapperCol={{ ...layout.wrapperCol, offset: 16 }}>
                        <Button type="primary" htmlType="submit" >
                            Submit
                        </Button>
                        &nbsp;
                        <Button type="primary" onClick={() => { (addHandleCancel()) }} danger>
                            取消
                        </Button>
                    </Form.Item>
                </Form>
            </Modal>
 <Button type="primary" onClick={showModal}> <EditOutlined /> 添加商品 </Button>

分页与搜索

我们在获取数据的时候，就获取我们的分页条数和总数以及搜索的关键字，然后在分页中进行数据属性的配置即可

  // 搜索 
    let [search, setSearch] = useState("")
    // 总条数
    let [total, setTotal] = useState(0)
    // 当前页
    let [page, setPage] = useState(1)
   // 每页条数 
    let [pageSize, setPageSize] = useState(2)
   // 搜索 
    const onSearch = (val) => {
        setSearch(val)
    }
    // 分页
    const onChange = (page, pageSize) => {
        setPage(page)
        setPageSize(pageSize)
    }
 // 初始化请求数据 用户
    const getUserData = async () => {
        console.log(pageSize);
        console.log(search);
        console.log(page);
        let { data } = await axios.get(`goods?pagenum=${page}&query=${search}&pagesize=${pageSize}`)
        console.log(data.goods);
        if (data) {
            setTotal(data.total);
            setUserData(data.goods);
        }
    } 
<Search allowClear placeholder="input search text" onSearch={onSearch} enterButton style={{ width: 300, height: 60 }} />
 <Pagination
                    className='pagination'
                    total={total}
                    showSizeChanger
                    showQuickJumper
                    pageSizeOptions={[10, 20, 30]}
                    defaultPageSize={2}
                    showTotal={(total) => `Total ${total} items`}
                    onChange={onChange}
                />

修改商品

我们在点击修改弹出对话框的同时，需要把数据绑定到输入框内，我们利用formRef.current.setFieldsValue进行数据回填，然后请求修改接口即可

    // 修改弹出框
    const [isModalVisible, setIsModalVisible] = useState(false); 
    // 修改弹出框，数据回填
    const showedit = async (e) => {
        setIsModalVisible(true);
        setgoodid(e)
        let { data } = await axios.get(`goods/${e}`)
        console.log(data);
        formRef.current.setFieldsValue({
            goods_name: data.goods_name,
            goods_price: data.goods_price,
            goods_number: data.goods_number,
            goods_weight: data.goods_weight
        })
    };
  // 修改取消按钮
    const editHandleCancel = () => {
        setIsModalVisible(false)
    }
// 修改商品
    const onFinish = async (values) => {
        let { meta } = await axios.put(`goods/${goodid}`, {
            goods_name: values.goods_name,
            goods_number: values.goods_number,
            goods_price: values.goods_price,
            goods_weight: values.goods_weight
        })
        // console.log(data);
        if (meta.status === 200) {
            message.success(meta.msg)
            setIsModalVisible(false);
            getUserData()
        } else {
            message.info(meta.msg)
            setIsModalVisible(false);
        }
    };
 <Button type="primary" size="small" onClick={() => { showedit(record.goods_id) }}> <EditOutlined /> </Button>
 {/* 修改弹出框 */}
            <Modal title="修改商品" visible={isModalVisible} footer={null}>
                <Form
                    name="basic"
                    labelCol={{ span: 4 }}
                    wrapperCol={{ span: 16 }}
                    initialValues={{ remember: true }}
                    onFinish={onFinish}
                    onFinishFailed={onFinishFailed}
                    autoComplete="off"
                    {...layout}
                    ref={formRef}
                >
                    <Form.Item
                        label="商品名称"
                        name="goods_name"
                        rules={[{ required: true, message: '请输入商品名称' }]}
                    >
                        <Input />
                    </Form.Item>
                    <Form.Item
                        label="商品价格"
                        name="goods_price"
                        rules={[{ required: true, message: '请输入商品价格' }]}
                    >
                        <Input />
                    </Form.Item>
                    <Form.Item
                        label="商品数量"
                        name="goods_number"
                        rules={[{ required: true, message: '请输入商品数量' }]}
                    >
                        <Input />
                    </Form.Item>
                    <Form.Item
                        label="商品重量"
                        name="goods_weight"
                        rules={[{ required: true, message: '请输入商品重量' }]}
                    >
                        <Input />
                    </Form.Item>
 
                    <Form.Item wrapperCol={{ ...layout.wrapperCol, offset: 16 }}>
                        <Button type="primary" htmlType="submit">
                            Submit
                        </Button>
                        &nbsp;
                        <Button type="primary" onClick={() => { (editHandleCancel()) }} danger>
                            取消
                        </Button>
                    </Form.Item>
                </Form>
            </Modal>

删除商品

点击删除按钮传递一个id，然后请求删除接口即可

    // 删除
    const delGoods = async (e) => {
        console.log(e);
        let { meta } = await axios.delete(`goods/${e}`)
        switch (meta.status) {
            case 200:
                message.success(meta.msg)
                break;
            default:
                message.warning("删除失败")
                break;
        }
        getUserData()
    }
<Button type="primary" size="small" danger onClick={() => { delGoods(record.goods_id) }} > <DeleteOutlined /> </Button>
