经过几天的尝试，我终于找到了答案。现在我想在这里分享我的步骤和代码，以帮助其他人。
1）获取您想要连接的网站的证书
echo | openssl s_client -connect ${MY_SERVER}:443 2>&1 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > mycert.pem
2) 要创建您的密钥，您需要BouncyCastle库，您可以在此处下载：这里
keytool -import -v -trustcacerts -alias 0 -file mycert.pem -keystore “store_directory/mykst“ -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath “directory_of_bouncycastle/bcprov-jdk16-145.jar” -storepass mypassword
3) 检查密钥是否已创建
keytool -list -keystore "carpeta_almacen/mykst" -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath "directory_of_bouncycastle/bcprov-jdk16-145.jar" -storetype BKS -storepass mypassword
您应该看到类似于以下内容：
密钥存储类型：BKS
密钥存储提供者：BC
您的密钥存储包含条目1
0, 07-12-2011，trustedCertEntry，
证书指纹（MD5）：
55:FD:E5:E3:8A:4C:D6:B8:69:EB:6A:49:05:5F:18:48
4) 然后您需要将文件“mykst”复制到您的Android项目中的“res / raw”目录中（如果不存在，请创建它）。
5) 在Android清单中添加权限。
<uses-permission android:name="android.permission.INTERNET"/>
6) 这里是代码！
