我这里采用RestTemplate的方式调用https请求请求第三方接口获取数据证书由第三方私自签发的证书我们构建的是一个springboot的API项目。

2.构建一个RestTemplateConfig
构建RestTemplateConfig为了初始化RestTemplate让它具备验证证书功能。
/*** Author: LongGE* Date: 2023-08-28* Description:*/
Configuration
public class RestTemplateConfig {/*** 1.创建一个KeyStore并将需要信任的证书加载到KeyStore中。示例代码如下* return* throws CertificateException* throws IOException* throws KeyStoreException* throws NoSuchAlgorithmException*/Beanpublic KeyStore createKeyStore() throws CertificateException, IOException, KeyStoreException, NoSuchAlgorithmException {CertificateFactory certFactory CertificateFactory.getInstance(X.509);FileInputStream inputStream new FileInputStream(D:\\WorkSpace\\local\\online-project\\RequestSpringBoot\\src\\main\\resources\\my-certificate.crt);X509Certificate certificate (X509Certificate) certFactory.generateCertificate(inputStream);KeyStore keyStore KeyStore.getInstance(KeyStore.getDefaultType());keyStore.load(null, null);keyStore.setCertificateEntry(my-cert, certificate);return keyStore;}/*** 2.创建一个TrustManagerFactory使用上述创建的KeyStore来初始化它* return* throws CertificateException* throws NoSuchAlgorithmException* throws KeyStoreException* throws IOException*/Beanpublic TrustManagerFactory createTrustManagerFactory() throws CertificateException, NoSuchAlgorithmException, KeyStoreException, IOException {KeyStore keyStore createKeyStore();TrustManagerFactory trustManagerFactory TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());trustManagerFactory.init(keyStore);return trustManagerFactory;}/*** 3.创建一个SSLContext并使用上述创建的TrustManagerFactory来初始化它。* return* throws NoSuchAlgorithmException* throws CertificateException* throws KeyStoreException* throws IOException* throws KeyManagementException*/Beanpublic SSLContext createSSLContext() throws NoSuchAlgorithmException, CertificateException, KeyStoreException, IOException, KeyManagementException {TrustManagerFactory trustManagerFactory createTrustManagerFactory();SSLContext sslContext SSLContext.getInstance(TLS);sslContext.init(null, trustManagerFactory.getTrustManagers(), new SecureRandom());return sslContext;}/*** 4.创建一个HttpsURLConnectionFactory使用上述创建的SSLContext来设置HttpsURLConnection的SSLSocketFactory。* return* throws CertificateException* throws NoSuchAlgorithmException* throws KeyStoreException* throws KeyManagementException* throws IOException*/Beanpublic RestTemplate createRestTemplate() throws CertificateException, NoSuchAlgorithmException, KeyStoreException, KeyManagementException, IOException {SSLContext sslContext createSSLContext();HttpClientBuilder httpClientBuilder HttpClientBuilder.create();httpClientBuilder.setSSLContext(sslContext);// 创建HttpComponentsClientHttpRequestFactoryHttpComponentsClientHttpRequestFactory requestFactory new HttpComponentsClientHttpRequestFactory();requestFactory.setHttpClient(httpClientBuilder.build());// 创建RestTemplate并设置自定义的SSLSocketFactoryRestTemplate restTemplate new RestTemplate(requestFactory);return restTemplate;}}二.使用方案
这样构建好的RestTemplate我们在Controller或者Service就可以通过Autowried注解引入。
RestController
RequestMapping(/TestController)
public class TestController {Autowiredprivate RestTemplate restTemplate;private String url https://www.houpu.com;private String relativePath2 /ResponseController/getTestMapping;GetMapping(/test02)public String test02() {//发起请求String fullUrl2 UriComponentsBuilder.fromHttpUrl(url).path(relativePath2).toUriString();String response2 restTemplate.getForObject(fullUrl2, String.class);System.out.println(response2);return response2;}}
