浏览器中的空 HTTP 响应 headers 但在 POSTMAN 中填写

Empty HTTP response headers in browser but filled in POSTMAN

我创建了一个带有 React 前端的 Spring 引导后端。

这对我来说没有意义。

代码: https://github.com/The-Taskmanager/SelfServiceWebwizard

后端映射

@PostMapping("/signin")

public ResponseEntity<?> authenticateUser(@Valid @RequestBody LoginRequest loginRequest) {

    Authentication authentication = authenticationManager.authenticate(
            new UsernamePasswordAuthenticationToken(
                    loginRequest.getUsernameOrEmail(),
                    loginRequest.getPassword()
            )
    );

    SecurityContextHolder.getContext().setAuthentication(authentication);

    String jwt = tokenProvider.generateToken(authentication);
    HttpHeaders headers = new HttpHeaders();
    headers.add("Mustermann", "Max");
    headers.add("Content-Type", "application/json");
    headers.add("Authorization", new JwtAuthenticationResponse(jwt).getAccessToken());
    return ResponseEntity.ok().headers(headers).body(new JwtAuthenticationResponse(jwt));

}

前端请求

login(username: string, password: string) {

    fetch('http://localhost:8080/api/auth/signin', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            "usernameOrEmail": username,
            "password": password
        })
    }).then(response => {
        console.log(response);
        console.log(response.text());
        console.log(response.headers);
    })
        .catch(error => console.error(error));
}

更新 1: 添加了此方法,但浏览器中的 headers 仍然为空:

CorsConfigurationSource corsConfigurationSource() {
    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    CorsConfiguration config = new CorsConfiguration().applyPermitDefaultValues();
    source.registerCorsConfiguration("/**", config);
    return source;
}

更新2:

当我用 React 请求时,Spring Boot 显示这个错误:

ERROR 8876 --- [nio-8080-exec-4] c.s.jwt.JwtAuthenticationEntryPoint:  Responding with unauthorized error. Message - full authentication is required to access this resource

浏览器控制台:

当我用 Postman 请求时,Spring 启动时没有显示错误。

更新3:

Request-header 由 React 发送:

{
host=[localhost:8080],
content-type=[application/json],
cache-control=[no-cache],
user-agent=[Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0],
accept-encoding=[gzip, deflate],
content-length=[58],
referer=[http://localhost:8080/],
origin=[http://localhost:8080],
dnt=[1],
connection=[keep-alive],
accept-language=[de,en-US;q=0.7,en;q=0.3],
accept=[*/*]
}

Request-header POSTMAN 从 POSTMAN 控制台发送:

host:"localhost:8080"
content-type:"application/json"
cache-control:"no-cache"
user-agent:"PostmanRuntime/7.1.5"
accept-encoding:"gzip, deflate"
content-length:68
postman-token:"b00fd7a8-bd34-4a32-8681-990b04012e3b"
cookie:"JSESSIONID=2CAEC9280432DD13AABA53B73B7874AC"
accept:"*/*"

自己解决了

更改了前端获取方法中的代码

console.log(response.headers)

// changed to:

console.log(response.headers.get('Authorization')

所以 headers 一直都在那里,但我无法使用 React 在浏览器控制台中记录它们。

然而 UPDATE2 中存在 Spring 引导(完全身份验证)和浏览器 (401) 错误。不知道这是从哪里来的。
