【问题描述】:
我正在使用 react-material-dashboard 查看管理员的统计信息。
我想在表格中显示我的所有用户,以便在管理仪表板中查看。我正在使用 Express 从我的数据库中获取用户,但是当我在浏览器中运行时,我收到了 GET http://localhost:3001/api/fetchUsers 404 (Not Found) 错误。
如何在我的 react-material-dashboard 中显示我的所有用户?
我做错了什么?
这是我的结构:
CustomersListResults.js:
import { useState, useEffect } from 'react';
import PerfectScrollbar from 'react-perfect-scrollbar';
import {
Box,
Card,
Table,
TableCell,
TableHead,
TablePagination,
TableRow,
} from '@material-ui/core';
import Axios from 'axios';
const CustomerListResults = () => {
const [limit, setLimit] = useState(10);
const [page, setPage] = useState(0);
useEffect(() => {
Axios.get('http://localhost:3001/api/fetchUsers').then((response) => {
console.log(response);
});
}, []);
const handleLimitChange = (event) => {
setLimit(event.target.value);
};
const handlePageChange = (event, newPage) => {
setPage(newPage);
};
return (
<Card>
<PerfectScrollbar>
<Box sx={{ minWidth: 1050 }}>
<Table>
<TableHead>
<TableRow>
<TableCell>
Account
</TableCell>
<TableCell>
Name
</TableCell>
<TableCell>
Email
</TableCell>
<TableCell>
Location
</TableCell>
<TableCell>
Phone
</TableCell>
<TableCell>
Registration date
</TableCell>
<TableCell>
Action
</TableCell>
</TableRow>
</TableHead>
</Table>
</Box>
</PerfectScrollbar>
<TablePagination
component="div"
count={5}
onPageChange={handlePageChange}
onRowsPerPageChange={handleLimitChange}
page={page}
rowsPerPage={limit}
rowsPerPageOptions={[5, 10, 25]}
/>
</Card>
);
};
export default CustomerListResults;
客户列表:
import { Helmet } from 'react-helmet';
import { Box, Container } from '@material-ui/core';
import CustomerListResults from '../components/customer/CustomerListResults';
import CustomerListToolbar from '../components/customer/CustomerListToolbar';
const CustomerList = () => (
<>
<Helmet>
<title>Customers | </title>
</Helmet>
<Box
sx={{
backgroundColor: 'background.default',
minHeight: '100%',
py: 3
}}
>
<Container maxWidth={false}>
<CustomerListToolbar />
<Box sx={{ pt: 3 }}>
<CustomerListResults />
</Box>
</Container>
</Box>
</>
);
export default CustomerList;
我的服务器 API:
//API To Get All Users
app.get("api/fetchUsers", (req, res) => {
db.query("SELECT * FROM users", (req, res) => {
if (err){
console.log(err)
}else{
console.log(result);
res.send(result)
}
});
});
