CORS Origin Spring Boot Jhipster - 飞行前失败

Question

我正在使用 jhipster v2.27.2 我通过取消注释 application.yml

中的行启用了 cors

jhipster:
async:
    corePoolSize: 2
    maxPoolSize: 50
    queueCapacity: 10000

cors: #By default CORS are not enabled. Uncomment to enable.
    allowed-origins: "*"
    allowed-methods: GET, PUT, POST, DELETE, OPTIONS
    allowed-headers: "*"
    exposed-headers:
    allow-credentials: true
    max-age: 1800

在"WebConfigurer"

@Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = props.getCors();
        if (config.getAllowedOrigins() != null && !config.getAllowedOrigins().isEmpty()) {
            source.registerCorsConfiguration("/api/**", config);
            source.registerCorsConfiguration("/v2/api-docs", config);
            source.registerCorsConfiguration("/oauth/**", config);
        }
        return new CorsFilter(source);
    }

但是当我请求访问令牌时，我仍然看到这个错误

http://localhost:8080/oauth/token?username=admin&password=admin&grant_type=password&scope=read. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9090' is therefore not allowed access. The response had HTTP status code 401.

Answer 1

看起来像默认值 SecurityConfiguration，它没有跳过 OPTIONS 的安全检查。

尝试将以下 antMatcher 添加到 SecurityConfiguration.java

中的 protected void configure(HttpSecurity http) 方法

.antMatchers(org.springframework.http.HttpMethod.OPTIONS, "/api/**").permitAll()

Answer 2

如果您忘记在指定的 URLs.In 上注册 cors，有时会出现此问题 WebConfigurer 查找 corsFilter 并添加这些行

 log.debug("Registering CORS filter");
        source.registerCorsConfiguration("/api/**", config);

Answer 3

SecurityConfiguration.java中的另一个选项。不是在 configure(HttpSecurity) 覆盖中使用 antMatcher，而是在 configure(WebSecurity) 覆盖中添加它...

public void configure(WebSecurity web) throws Exception {
    web.ignoring()
        .antMatchers(HttpMethod.OPTIONS, "/**")
