然而，我发现当我调用endpoint时，可以在日志中看到以下输出：

编辑2：我为网关服务启用了日志记录，这是每当我调用/user/login时的输出。根据日志，网关正确匹配/users/login/，但随后由于某种原因开始仅使用/login。

我设法修好了。问题实际上不是在网关，而是在用户服务。它的安全配置不正确，并且在访问其endpoint时需要登录。因此，当我调用任何endpoint时，它会被重定向到/login。

我将以下代码添加到服务中，它现在可以正常工作了。

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity.authorizeRequests().antMatchers("/").permitAll();
        httpSecurity.cors().and().csrf().disable();
    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("*"));
        configuration.setAllowedHeaders(Arrays.asList("*"));
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

这可能不是一个合适的解决方案，但在非生产代码上，它可以完成工作。

  • Spring云网关中的路由顺序

    我们使用的实现以编程方式实现路由。我们有两个服务，它们应该在相同的路由路径上注册，如果另一个不存在，其中一个将作为后备。具有特定路径的首选路由是： 因此，当调用时，应该使用第一条路由，而当调用时，应该使用第二条路由。 问题是，即使是路线上的order属性似乎也不能解决这个问题；目前，我们发现没有可能设置这种路线的顺序/优先级。这是intender吗？
