[英]Taking Axios.get() data and displaying it in React component
我無法通過表格中的 React 組件顯示數據。
目標:在 React 組件中顯示 MongoDB 數據,並了解為什么此數據處理不起作用。
這里出了什么問題? 我知道這不是 HTTP 請求,所以數據格式似乎是問題所在。
以供參考:
HTTP 請求
app.get('/api/people/fetchall', requireLogin, async (req, res) => {
const userContacts = await User.findOne({_id: req.user._id}, 'contacts');
res.send(userContacts['contacts']);
console.log(userContacts['contacts']);
});
觸點 HTTP POST
app.post('/api/people/add', requireLogin, async (req, res) => {
console.log(req.body.name);
const { name, company, linkedin, department, email } = req.body;
const newcontact = new AddContact({
_user: req.user.id,
name: name,
company: company,
linkedin: linkedin,
department: department,
email: email,
dateUpdated: Date.now()
});
User.findByIdAndUpdate(
{_id: req.user._id},
{$push: {contacts: newcontact}},
{safe: true, upsert: true},
function(err, model) {
console.log(err);
}
);
//Our user to add Contact to, and find the contacts array
const user = await req.user.save();
});
React 組件,以及在組件內加載數據
import React, {Component} from 'react';
import MaterialTable from 'material-table';
import axios from 'axios';
const fakedata = [{'name': 'Elliot Kang','company': 'Employableh','linkedin': 'linkedin.com/en/elliotkang7',
'department': 'PM','email': 'elliot@employableh.com'}, {'name': 'Elliot Kon','company': 'Employableh','linkedin': 'linkedin.com/en/elliotkang7',
'department': 'PM','email': 'elliot@employableh.com'}];
class ContactDisplay extends Component {
constructor() {
super();
this.state= {contacts: {},
columns: [
{title: 'Name', field: 'name'},
{title: 'Company', field: 'company'},
{title: 'Linkedin', field: 'linkedin'},
{title: 'Department', field: 'department'},
{title: 'Email', field: 'email'}
],
}
}
handleChange(event) {
this.setState({ [event.target.name]: event.target.value });
}
componentDidMount() {
axios.get('/api/people/fetchall').then(res => {
console.log(res.data);
this.setState({contacts: res.data});
});
}
render() {
return(
<MaterialTable
title='Contacts'
columns = {this.state.columns}
data = {fakedata}
/>
);
}
}
export default ContactDisplay;
我認為問題可能是您忘記更改
data = { fakedata }
至
data = { this.state.contacts }
在渲染方法中。
所以你需要做兩件事...
