将Angular与JWT的Spring Boot连接时发生CORS错误 [英] CORS error while connecting Angular with spring boot for JWT
本文介绍了将Angular与JWT的Spring Boot连接时发生CORS错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是我每次登录时都会收到的浏览器控制台错误(对服务器进行后调用
This is the error in browser console I get whenever I log in (make a post-call to the server
我正在尝试使用REST连接角度引导和弹簧引导，以实现JWT身份验证和授权.
I am trying to connect angular and spring boot using REST for implementing JWT Authentication and Authorization.
这是我的Angular服务，用于对spring boot进行登录调用( http://localhost:8080/login )是默认的/login页面，它是spring boot带有spring-starter-security(*我认为*)
This is my Angular service that makes a login call to the spring boot (http://localhost:8080/login) which is a default /login page which spring boot gives with spring-starter-security (* I think *)
export class JwtService {
constructor(private _http: HttpClient) {
}
submitData(credential){
credential = JSON.stringify(credential);
let reqHeader = new HttpHeaders();
return this._http.post("http://localhost:8080/login",credential);
}
}
下面是我的Spring Boot安全性配置类
below is my spring boot security configuring class
@EnableWebSecurity
@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter
implements WebMvcConfigurer{
private CustomAdminUserDetailService adminUserService;
private AdminDao adminDao;
public SecurityConfiguration(CustomAdminUserDetailService adminUserService, AdminDao adminDao) {
super();
this.adminUserService = adminUserService;
this.adminDao = adminDao;
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authenticationProvider());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.addFilter(new JwtAuthenticationFilter(authenticationManager()))
.addFilter(new JwtAuthorizationFilter(authenticationManager(), this.adminDao))
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests().antMatchers("/login").permitAll()
.antMatchers("/home").hasRole("ADMIN");
}
@Bean
DaoAuthenticationProvider authenticationProvider() {
DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
daoAuthenticationProvider.setUserDetailsService(adminUserService);
daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
return daoAuthenticationProvider;
}
@Bean
PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("*").allowedMethods("GET", "POST", "PUT", "PATCH", "DELETE", "OPTIONS")
.allowedHeaders("*")
.allowedOrigins("http://localhost:4200/");
WebMvcConfigurer.super.addCorsMappings(registry);
}
我已经用邮递员对其进行了测试，并且可以正常工作，给出了正确的响应，并且Bearer令牌符合预期，但是它不能与Angular一起使用
I have tested it with the postman and it works fine, giving proper response and the Bearer token as expected but it is not working with Angular
这是我用Postman测试时的屏幕截图
This is the screenshot when I am testing it with Postman
我也尝试过在请求中包含Allow-cross-origin标头为
I have also tried including Allow-cross-origin header in the request as
export class JwtService {
constructor(private _http: HttpClient) {
}
submitData(credential){
credential = JSON.stringify(credential);
let reqHeader = new HttpHeaders();
reqHeader.set('Access-Control-Allow-Origin','*');
return this._http.post("http://localhost:8080/login",credential,{headers:reqHeader});
}
}
这是我对/home的restcontroller(我没有包括/login，因为默认情况下，Spring Boot会给出
This is my restcontroller for /home (I haven't included /login as spring boot gives it by default 'I might be wrong cz i am not sure')
@RestController
@CrossOrigin(origins = "http://localhost:4200")
public class AdminController {
@GetMapping("/home")
public String welcome() {
return "Hello world";
}
}
我尝试使用Spring Boot调试，这就是我所得到的，
I tried debugging using spring boot and this is what i got,

这是我正在使用的AuthenticationFilter类
This is the AuthenticationFilter class i am using
public class JwtAuthenticationFilter extends UsernamePasswordAuthenticationFilter{
private AuthenticationManager authenticationManager;
public JwtAuthenticationFilter(AuthenticationManager authenticationManager) {
// super();
System.out.println("in constructor");
this.authenticationManager = authenticationManager;
}
@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
throws AuthenticationException {
System.out.println("in attempt authentication");
LoginViewModel credentials = null;
try {
credentials = new ObjectMapper().readValue(request.getInputStream(), LoginViewModel.class);
} catch (JsonParseException e) {
System.out.println("in json parse");
e.printStackTrace();
} catch (JsonMappingException e) {
System.out.println("in json map");
e.printStackTrace();
} catch (IOException e) {
System.out.println("in io exception");
e.printStackTrace();
}
System.out.println("spring boot generating token to authenticate authentication");
UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(
credentials.getUsername(),
credentials.getPassword(),
new ArrayList<>());
Authentication auth = authenticationManager.authenticate(token);
return auth;
}
@Override
protected void successfulAuthentication(
HttpServletRequest request,
HttpServletResponse response,
FilterChain chain,
Authentication authResult) throws IOException, ServletException {
System.out.println("spring boot successfully authentication the user");
System.out.println("generating jwt token");
User user = (User) authResult.getPrincipal();
String token = JWT.create()
.withSubject(user.getUsername())
.withExpiresAt(new Date(System.currentTimeMillis()+ 1000 * 60 * 60 * 1))
.sign(Algorithm.HMAC512("adhfjhewr******fk23"));
response.addHeader("Authorization", "Bearer "+token);
System.out.println("sending response to the user");
}
请求中的标头是

如何是第一个问题，但为什么更重要
How is the first question but Why is more important
推荐答案
我在addCorsMappings()方法中错误地编写了*而不是/**
I have mistakenly written * instead of /** in addCorsMappings() method
现在方法看起来像
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedMethods("GET", "POST", "PUT", "PATCH", "DELETE", "OPTIONS")
.allowedHeaders("*")
.allowedOrigins("http://localhost:4200","http://localhost:8080");
WebMvcConfigurer.super.addCorsMappings(registry);
}
此外，此后Angular客户端无法获取响应，并为空 在响应中，所以我将其修改为
Also, After that Angular client wasn't able to grab the response and was getting null in the response so I modifed it as
submitData(credential){
credential = JSON.stringify(credential);
return this._http.post("http://localhost:8080/login",credential,{observe: 'response'});
}
现在我正在获得Http响应.
Now I am getting Http response.
这篇关于将Angular与JWT的Spring Boot连接时发生CORS错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
