用於自簽名憑證的自訂SSL 套接字工廠
要使用自簽名憑證連接到網站,Java 應用程式必須修改其預設行為。以下是如何在不影響使用自訂SSLSocket 工廠的情況下實現您的目標:
建立SSLSocket 工廠:
設定SSLSocket Factory:
範例程式碼:
import javax.net.ssl.*; import java.io.FileInputStream; import java.security.KeyStore; public class CustomSSLContext { public static SSLSocketFactory getSSLSocketFactory() { // Load the keystore with the self-signed certificate KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType()); keyStore.load(new FileInputStream("truststore.jks"), "password".toCharArray()); // Create a TrustManagerFactory and initialize it with the keystore TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm()); tmf.init(keyStore); // Create an SSLContext and initialize it with the TrustManagerFactory SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(null, tmf.getTrustManagers(), null); // Get the SSLSocketFactory from the SSLContext return sslContext.getSocketFactory(); } public static void main(String[] args) { // Create an HttpsURLConnection with the custom SSLSocketFactory URL url = new URL("https://host.example.com/"); HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setSSLSocketFactory(getSSLSocketFactory()); // Send the request to the website conn.setMethod("POST"); conn.getOutputStream().write("data".getBytes()); // Read the response from the website conn.getInputStream().read(); } }
這個方法可以讓你使用自簽證憑證連結到網站,而不影響應用程式中的其他連接或需要修改JRE。
