整體頁面效果
項目技術點
- antd組件庫，@ant-design/icons antd的圖標庫
- axios 接口請求，攔截器配置
- node-sass sass-loader css樣式的一個嵌套
- react-router-dom react路由使用
- react-redux redux
- hooks：大多數我們用的是函數組件，函數組件沒有state屬性，所以我們使用hooks來初始化數據，并且函數組件沒有生命周期
攔截器的配置
由于我們登錄成功之后，需要我們獲取到token令牌之后，我們才能獲取到數據，如果每個頁面都需要獲取一次token，代碼比較啰嗦，所以我們配置了一個攔截器
需要授權的 API ，必須在請求頭中使用 Authorization 字段提供 token 令牌
//配置攔截器
import axios from "axios";
//2. 創建對象
const Server = axios.create({
baseURL:"http://api.xiaohuihui0728.cn:8888/api/private/v1/",//基地址
timeout:5000,
})
//3. 請求攔截器
Server.interceptors.request.use((config)=>{
//前置攔截器請求發送出去之前觸發
console.log(config);
//增加一個token值
let token = sessionStorage.getItem("token");
config.headers["Authorization"] = token;
return config;
},(err)=>Promise.reject(err));
//4. 響應攔截器
Server.interceptors.response.use((response)=>{
//請求成功，服務端返回數據到客戶端之前觸發
return response.data;
},(err)=>Promise.reject(err))
//5.拋出Serve對象的內容
export default Server;主頁面
我們的數據寫在columns里面，在里面的dataIndex綁定我們獲取到的數據
const columns = [
{
title: '商品名稱',
dataIndex: 'goods_name',
key: 'username',
},
{
title: '商品價格',
dataIndex: 'goods_price',
key: 'email',
},
{
title: '商品重量',
dataIndex: 'goods_weight',
key: 'mobile',
},
{
title: '創建時間',
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>
<Button type="primary" size="small" danger onClick={() => { delGoods(record.goods_id) }} > <DeleteOutlined /> </Button>
</>
)
}
}
];
const [userData, setUserData] = useState([])
// 初始化數據
useEffect(() => {
getUserData()
setPage(1)
}, [search, page, pageSize])
// 初始化請求數據 用戶
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
添加彈出對話框，添加里面有一個上傳圖片，我們上傳的圖片有一個單獨的添加接口，所以我們使用action屬性綁定我們要上傳的路徑，headres獲取token，使用onChange獲取圖片上傳的路徑，然后在我們點擊提交form表單數據時把圖片臨時地址添加成功
// 添加彈窗狀態
const [addIsModalVisible, setAddIsModalVisible] = useState(false);
// 存圖片
let [img,setimg] = useState("");
// 添加取消
const addHandleCancel = () => {
setAddIsModalVisible(false);
};
//獲取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()
}
//圖片上傳
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}>

<Button type="primary" onClick={showModal}> <EditOutlined /> 添加商品 </Button>分頁與搜索
我們在獲取數據的時候，就獲取我們的分頁條數和總數以及搜索的關鍵字，然后在分頁中進行數據屬性的配置即可
// 搜索
let [search, setSearch] = useState("")
// 總條數
let [total, setTotal] = useState(0)
// 當前頁
let [page, setPage] = useState(1)
// 每頁條數
let [pageSize, setPageSize] = useState(2)
// 搜索
const onSearch = (val) => {
setSearch(val)
}
// 分頁
const onChange = (page, pageSize) => {
setPage(page)
setPageSize(pageSize)
}
// 初始化請求數據 用戶
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 ${total} items`}
onChange={onChange}
/>修改商品
我們在點擊修改彈出對話框的同時，需要把數據綁定到輸入框內，我們利用formRef.current.setFieldsValue進行數據回填，然后請求修改接口即可
// 修改彈出框
const [isModalVisible, setIsModalVisible] = useState(false);
// 修改彈出框，數據回填
const showedit = async (e) => {
setIsModalVisible(true);
setgoodid(e)
let { data } = await axios.get(`goods/${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
})
};
// 修改取消按鈕
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);
}
};

點擊刪除按鈕傳遞一個id，然后請求刪除接口即可
// 刪除

let { meta } = await axios.delete(`goods/${e}`)
switch (meta.status) {
