隨著網路的發展,線上問答應用程式越來越受歡迎。在這篇文章中,我們將介紹如何使用Go語言和React建立一個線上問答應用程式。
在建立任何應用程式之前,首先需要確定應用程式的需求。對於線上問答應用程式來說,以下是一些可能的需求:
package main import ( "github.com/gin-gonic/gin" ) func main() { r := gin.Default() // 路由定义在这里 r.Run() }
npx create-react-app qanda-app
npm install antd axios --save
import React, {useState} from 'react'; import './App.css'; import {Layout, Menu, Breadcrumb, Form, Input, Button, message} from 'antd'; import axios from 'axios'; const {Header, Content, Footer} = Layout; function App() { const [form] = Form.useForm(); const [user, setUser] = useState(null); const onFinish = async (values) => { try { const response = await axios.post('/api/user/register', values); setUser(response.data); message.success('注册成功'); } catch (error) { message.error(error.response.data); } }; const login = async (username, password) => { try { const response = await axios.post('/api/user/login', {username, password}); setUser(response.data); message.success('登录成功'); } catch (error) { message.error(error.response.data); } } return ( <Layout className="layout"> <Header> <div className="logo" /> <Menu theme="dark" mode="horizontal" defaultSelectedKeys={['1']}> <Menu.Item key="1">主页</Menu.Item> </Menu> </Header> <Content style={{padding: '0 50px'}}> <Breadcrumb style={{margin: '16px 0'}}> <Breadcrumb.Item>主页</Breadcrumb.Item> </Breadcrumb> <div className="site-layout-content"> {!user ? <div className="login-form"> <h1>注册</h1> <Form form={form} onFinish={onFinish}> <Form.Item name="username" rules={[{required: true, message: '请输入用户名'}]}> <Input placeholder="用户名" /> </Form.Item> <Form.Item name="password" rules={[{required: true, message: '请输入密码'}]}> <Input.Password placeholder="密码" /> </Form.Item> <Form.Item name="confirmPassword" dependencies={['password']} rules={[ {required: true, message: '请确认密码'}, ({getFieldValue}) => ({ validator(rule, value) { if (!value || getFieldValue('password') === value) { return Promise.resolve(); } return Promise.reject('两次输入的密码不一致'); } }) ]}> <Input.Password placeholder="确认密码" /> </Form.Item> <Form.Item> <Button type="primary" htmlType="submit"> 注册 </Button> <a href="#" onClick={() => message.warning('该功能尚未实现')}> 已有账户?登录! </a> </Form.Item> </Form> </div> : <div> <h1>欢迎 {user.username}!</h1> <a href="#" onClick={() => message.warning('该功能尚未实现')}> 提问 </a> </div> } </div> </Content> <Footer style={{textAlign: 'center'}}>Ant Design ©2021 Created by Ant UED</Footer> </Layout> ); } export default App;
