public List<ResponseStatus> subscribeDel(HttpServletRequest request)中参数啥意思

这是一个Java方法,它接收一个HttpServletRequest对象作为参数。HttpServletRequest对象是一个Java Servlet API接口,它提供了有关HTTP请求的信息,例如请求的URL、请求头、请求参数等。在这个方法中,HttpServletRequest对象被用来获取HTTP请求中的一些参数,从而执行一些订阅操作。该方法返回一个ResponseStatus对象列表,其中包含了订阅操作的结果状态,例如成功、失败等。

public ModelAndView stopMessage(HttpServletRequest request,HttpServletResponse response) throws Exception { ModelAndView mav = new ModelAndView("apps/notemessage/showNoteMessageList"); String affairIds = request.getParameter("affairId"); List<String> list=new ArrayList<>(); //遍历affairIds 前端传过来的如果是一个不带、 如果是多个带、 if (affairIds.contains("、")){ for (String id : affairIds.split("、")) { list.add(id); } }else { list.add(affairIds); } //赋值给状态 Map<String,String> map=new HashMap(); map.put("status","Z"); noteMessageManager.updateData("smsserver_out",map,list); return mav; }给我这段代码加上注释
这段代码的功能是停止消息,具体实现细节如下:
```java
public ModelAndView stopMessage(HttpServletRequest request, HttpServletResponse response) throws Exception {
// 创建一个 ModelAndView 对象并将视图名称设置为 "apps/notemessage/showNoteMessageList"
ModelAndView mav = new ModelAndView("apps/notemessage/showNoteMessageList");
// 获取请求参数 affairIds
String affairIds = request.getParameter("affairId");
// 创建一个字符串类型的列表 list
List<String> list = new ArrayList<>();
// 遍历 affairIds,如果字符串中包含 "、",则将 affairIds 按 "、" 分割,将每个部分添加到 list 中
if (affairIds.contains("、")) {
for (String id : affairIds.split("、")) {
list.add(id);
}
} else {
// 如果字符串中不包含 "、",则直接将 affairIds 添加到 list 中
list.add(affairIds);
}
// 创建一个字符串类型的 Map 对象 map,将 "status" 的值设置为 "Z"
Map<String, String> map = new HashMap();
map.put("status", "Z");
// 调用 noteMessageManager 的 updateData 方法,更新 "smsserver_out" 表中 id 在 list 中的数据,将状态改为 "Z"
noteMessageManager.updateData("smsserver_out", map, list);
// 返回 ModelAndView 对象
return mav;
}
```
请写一个调用微信auth.code2Session方法后与自定义登录态关联的使用Spring Security 框架完整实例的springboot微信小程序项目,请注意项目需要引入<artifactId>weixin-java-miniapp</artifactId>
好的,下面是一个基于Spring Security框架与微信小程序登录态关联的完整实例:
1.首先,我们需要引入相关依赖,在pom.xml文件中添加以下配置:
```xml
<dependency>
<groupId>com.github.binarywang</groupId>
<artifactId>weixin-java-miniapp</artifactId>
<version>3.9.0</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>5.4.6</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>5.4.6</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>5.4.6</version>
</dependency>
```
2.接着,我们需要在Spring Security的配置类中添加相关配置,代码如下:
```java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private WeixinMaService weixinMaService;
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/login/**", "/error/**").permitAll() // 放行登录页和错误页
.antMatchers("/**").authenticated(); // 其他请求需要认证
http.formLogin()
.loginPage("/login") // 自定义登录页
.loginProcessingUrl("/login") // 登录请求的URL
.successHandler(this::loginSuccessHandler) // 登录成功处理器
.failureHandler(this::loginFailureHandler) // 登录失败处理器
.permitAll();
http.logout()
.logoutUrl("/logout") // 退出登录请求的URL
.logoutSuccessUrl("/") // 退出登录成功后跳转的URL
.invalidateHttpSession(true)
.deleteCookies("JSESSIONID");
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(new WeixinMaAuthenticationProvider(weixinMaService));
}
private void loginSuccessHandler(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException {
String openid = (String) authentication.getPrincipal();
HttpSession session = request.getSession();
session.setAttribute("openid", openid);
response.sendRedirect("/");
}
private void loginFailureHandler(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException {
response.sendRedirect("/login?error");
}
}
```
3.在上面的配置类中,我们使用了WeixinMaAuthenticationProvider来实现微信小程序登录认证,该认证器的实现如下:
```java
public class WeixinMaAuthenticationProvider implements AuthenticationProvider {
private final WeixinMaService weixinMaService;
public WeixinMaAuthenticationProvider(WeixinMaService weixinMaService) {
this.weixinMaService = weixinMaService;
}
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
String code = (String) authentication.getCredentials();
WxMaJscode2SessionResult result;
try {
result = weixinMaService.getUserService().getSessionInfo(code);
} catch (WxErrorException e) {
throw new BadCredentialsException("获取用户信息失败", e);
}
String openid = result.getOpenid();
if (StringUtils.isBlank(openid)) {
throw new BadCredentialsException("获取用户信息失败");
}
return new UsernamePasswordAuthenticationToken(openid, null, Collections.emptyList());
}
@Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
```
4.接下来,我们需要在登录页中添加微信小程序登录的按钮,并实现相关的逻辑,代码如下:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>登录</title>
</head>
<body>
<h1>登录</h1>
<form method="post">
<input type="text" name="username" placeholder="请输入用户名">
<input type="password" name="password" placeholder="请输入密码">
<button type="submit">登录</button>
</form>
<button id="loginBtn">微信登录</button>
<script src="https://res.wx.qq.com/open/js/jweixin-1.6.0.js"></script>
<script>
wx.miniProgram.getEnv(function (res) {
if (res.miniprogram) {
document.getElementById('loginBtn').addEventListener('click', function () {
wx.miniProgram.login({
success: function (res) {
const code = res.code;
const xhr = new XMLHttpRequest();
xhr.open('POST', '/login');
xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xhr.onreadystatechange = function () {
if (xhr.readyState === 4) {
if (xhr.status === 200) {
window.location.href = '/';
} else {
alert('微信登录失败');
}
}
};
xhr.send('username=' + code + '&password=');
},
fail: function () {
alert('微信登录失败');
}
});
});
} else {
document.getElementById('loginBtn').style.display = 'none';
}
});
</script>
</body>
</html>
```
5.最后,我们需要在Controller中实现登录页的访问和退出登录的处理逻辑,代码如下:
```java
@Controller
public class LoginController {
@GetMapping("/login")
public String login() {
return "login";
}
@PostMapping("/login")
public void doLogin(HttpServletRequest request, HttpServletResponse response, String username, String password) throws IOException {
Authentication authentication = new UsernamePasswordAuthenticationToken(username, password);
Authentication result = SecurityContextHolder.getContext().getAuthenticationManager().authenticate(authentication);
SecurityContextHolder.getContext().setAuthentication(result);
}
@GetMapping("/logout")
public String logout(HttpSession session) {
session.invalidate();
return "redirect:/";
}
}
```
至此,基于Spring Security框架与微信小程序登录态关联的完整实例就结束了。其中,我们使用了WeixinMaAuthenticationProvider来实现微信小程序登录认证,使用了WeixinMaService来调用微信auth.code2Session方法获取用户信息,使用了HttpSession来存储用户登录态信息。同时,我们在登录页中添加了微信小程序登录的按钮,并实现了相关的逻辑。
