用于自签名证书的自定义 SSL 套接字工厂
要使用自签名证书连接到网站,Java 应用程序必须修改其默认行为。以下是如何在不影响使用自定义 SSLSocket 工厂的情况下实现您的目标:
创建 SSLSocket 工厂:
设置SSLSocket Factory:
示例代码:
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(); } }
这种方法可以让你使用自签名证书连接到网站,而不影响应用程序中的其他连接或需要修改 JRE。
