nacos整合feign使用https远程调用

要使用Nacos整合Feign进行HTTPS远程调用，需要以下步骤：

1. 在Nacos中注册服务，并启用HTTPS协议。

2. 在Feign的配置中添加HTTPS相关的配置，如下：

@Configuration
public class FeignConfig {

    @Bean
    public Client feignClient() {
        return new OkHttpClient.Builder()
                .sslSocketFactory(createSSLSocketFactory())
                .hostnameVerifier(createHostnameVerifier())
                .build();
    }

    private SSLSocketFactory createSSLSocketFactory() {
        try {
            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, new TrustManager[]{new X509TrustManager() {
                @Override
                public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                }

                @Override
                public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                }

                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }
            }}, new SecureRandom());
            return sslContext.getSocketFactory();
        } catch (NoSuchAlgorithmException | KeyManagementException e) {
            throw new RuntimeException(e);
        }
    }

    private HostnameVerifier createHostnameVerifier() {
        return (s, sslSession) -> true;
    }

}

3. 在Feign的接口上添加@FeignClient注解，并指定Nacos中注册的服务名和HTTPS协议，如下：

@FeignClient(name = "service-provider", url = "https://service-provider", configuration = FeignConfig.class)
public interface ServiceProviderClient {

    @GetMapping("/hello")
    String sayHello();

}

这样就可以使用Nacos整合Feign进行HTTPS远程调用了。
