springboot RestTemplate 访问 https post请求代码

以下是使用Spring Boot RestTemplate访问HTTPS的POST请求示例代码： ```java import org.springframework.http.HttpEntity; import org.springframework.http.HttpHeaders; import org.springframework.http.MediaType; import org.springframework.http.ResponseEntity; import org.springframework.http.client.SimpleClientHttpRequestFactory; import org.springframework.stereotype.Component; import org.springframework.web.client.RestTemplate; import javax.net.ssl.HostnameVerifier; import javax.net.ssl.HttpsURLConnection; import javax.net.ssl.SSLContext; import javax.net.ssl.SSLSession; import javax.net.ssl.TrustManager; import javax.net.ssl.X509TrustManager; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; import java.util.Collections; @Component public class HttpsPostRequest { public String sendPostRequest(String url, String data) throws Exception { // Create a trust manager that does not validate certificate chains TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() { public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {} public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {} public X509Certificate[] getAcceptedIssuers() { return new X509Certificate[0]; } } }; // Install the all-trusting trust manager SSLContext sslContext = SSLContext.getInstance("SSL"); sslContext.init(null, trustAllCerts, new java.security.SecureRandom()); HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory()); // Create all-trusting host name verifier HostnameVerifier allHostsValid = new HostnameVerifier() { public boolean verify(String hostname, SSLSession session) { return true; } }; // Install the all-trusting host verifier HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid); // Set request factory SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory(); requestFactory.setBufferRequestBody(false); // Create RestTemplate with request factory RestTemplate restTemplate = new RestTemplate(requestFactory); // Set headers HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED); headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON)); // Create HttpEntity with data and headers HttpEntity entity = new HttpEntity<>(data, headers); //
