當我嘗試使用自簽名證書連接到URL時,Java不允許我這樣做。在我的情況下,我無法使用自定義SSL套接字工廠而無需進行證書檢查,因此我需要使用PKS12證書並將其添加到可信存儲區中。 我的問題是 - 我有什麼行動來獲得PKS12證書?我通過瀏覽器工具(它是X.509)從URL導出證書,那我該怎麼辦?帶自簽名證書的SSL

How do I accept a self-signed certificate with a Java HttpsURLConnection?
HttpsURLConnection connection = (HttpsURLConnection) URL.openConnection();
connection.setSSLSocketFactory(SSLFACTORY);
connection.setMethod("POST");
KeyStore KEY_STORE = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(TRUST_STORE, PASSWORD);
TRUST_STORE.close();
TrustManagerFactory managerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
managerFactory.init(KEY_STORE);
SSLSocketFactoryEx SSLFACTORY = new SSLSocketFactoryEx();
connection.setSSLSocketFactory(factory);
connection.setRequestProperty("charset", "utf-8");

我推薦使用名爲InstallCert的工具。它將下載自簽名證書並將其導入新的信任庫/密鑰庫。
