一个完整的社交网站系统需要涉及到用户登录、发布动态、关注、评论、私信等各方面。这里提供一个简单的实现示例,供参考。
- 前端代码
前端使用Vue框架,以下是部分代码示例:
登录页:
<template>
<div>
<input type="text" v-model="username">
<input type="password" v-model="password">
<button @click="login">登录</button>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
username: '',
password: ''
}
},
methods: {
login() {
axios.post('/api/login', {
username: this.username,
password: this.password
}).then(res => {
// 登录成功,跳转到首页
});
}
}
}
</script>
首页:
<template>
<div>
<div v-for="post in posts" :key="post.id">
<h3>{{ post.title }}</h3>
<p>{{ post.content }}</p>
<button @click="likePost(post)">赞</button>
<button @click="comment(post)">评论</button>
</div>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
posts: []
}
},
methods: {
getPosts() {
axios.get('/api/posts').then(res => {
this.posts = res.data;
});
},
likePost(post) {
// 点赞
},
comment(post) {
// 评论
}
},
mounted() {
this.getPosts();
}
}
</script>
- 后端代码
后端使用Spring Boot框架,以下是部分代码示例:
登录Controller:
@RestController
@RequestMapping("/api")
public class LoginController {
@Autowired
private UserService userService;
@PostMapping("/login")
public String login(@RequestBody User user) {
if (userService.checkUser(user)) {
return "success";
} else {
return "failure";
}
}
}
UserService类:
@Service
public class UserService {
@Autowired
private UserRepository userRepository;
public boolean checkUser(User user) {
User userInDb = userRepository.findByUsername(user.getUsername());
if (userInDb != null && userInDb.getPassword().equals(user.getPassword())) {
return true;
} else {
return false;
}
}
}
PostController类:
@RestController
@RequestMapping("/api")
public class PostController {
@Autowired
private PostService postService;
@GetMapping("/posts")
public List<Post> getPosts() {
return postService.getAllPosts();
}
@PostMapping("/posts")
public void addPost(@RequestBody Post post) {
postService.addPost(post);
}
}
PostService类:
@Service
public class PostService {
@Autowired
private PostRepository postRepository;
public List<Post> getAllPosts() {
return postRepository.findAll();
}
public void addPost(Post post) {
postRepository.save(post);
}
}
PostRepository类:
public interface PostRepository extends JpaRepository<Post, Long> {
}
UserRepository类:
public interface UserRepository extends JpaRepository<User, Long> {
User findByUsername(String username);
}
Post类:
java
@Entity
public class Post {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String title;
private String content;
private LocalDateTime createTime;
// 省略getter和setter方法,以及构造方法等
}
User类:
java
@Entity
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String username;
private String password;
// 省略getter和setter方法,以及构造方法等
}
- 数据库代码
使用MySQL数据库,以下是部分代码示例:
创建数据库:
sql
CREATE DATABASE social;
创建用户表:
sql
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) DEFAULT NULL,
`password` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
创建动态表:文章来源:https://www.toymoban.com/news/detail-677156.html
sql
CREATE TABLE `post` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`title` varchar(255) DEFAULT NULL,
`content` text,
`create_time` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
以上是简单的实现示例,实际社交网站系统需要考虑更复杂的业务逻辑和安全性问题。完整的实现可参考相关开源项目,例如:https://github.com/b3log/symphony文章来源地址https://www.toymoban.com/news/detail-677156.html
