java 访问 https post请示 代码

以下是Java访问HTTPS的POST请求示例代码： ```java import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.URL; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; 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; public class HttpsPostRequest { public static void main(String[] args) throws Exception { String url = "https://example.com/api"; String data = "param1=value1¶m2=value2"; // 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); // Send POST request URL obj = new URL(url); HttpsURLConnection con = (HttpsURLConnection) obj.openConnection(); con.setRequestMethod("POST"); con.setDoOutput(true); con.getOutputStream().write(data.getBytes()); // Read response BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream())); String inputLine; StringBuffer response = new StringBuffer(); while ((inputLine = in.readLine()) != null) { response.append(inputLine); } in.close(); // Print response System.out.println(response.toString()); } } ``` 在这个示例中，我们创建了一个HTTPS的POST
