使用Cloudant的Liberty应用程序的SSL握手失败

Question

我一直坚持这一点比我想承认的要长。我想使用WebSphere Liberty连接到cloudant/couchdb。

我对Java应用程序开发，Liberty，Cloudant和Bluemix相当陌生。

我相信我需要为本地信任存储库中的cloudant添加SSL证书，但唯一的办法似乎是使用Websphere Application Server集成解决方案控制台，而我无法使用Liberty运行该控制台？

如果任何人都可以指引我朝着正确的方向，我将非常感激！

您需要添加远程服务器证书WAS的trustStore

获取远程证书（如：使用Linux/Mac上）： echo "" | openssl s_client -connect YOUR_REMOTE_SERVER:443 -showcerts 2>/dev/null | openssl x509 -out certfile.txt

导入证书trustStore文件： keytool -import -alias ca -file certfile.txt -keystore trust.jks -storepass changeit

在您的WAS server.xml中使用此JKS信托商店，将其复制到您的WAS（{WLP}/usr/servers/{YOUR_SERVER}/resources/security）中并将其添加到您的server.xml e.g：

<ssl id="defaultSSLSettings" sslProtocol="TLSv1.2" keyStoreRef="defaultKeyStore" 
    trustStoreRef="defaultTrustStore" /> 
<keyStore id="defaultKeyStore" location="${server.config.dir}/resources/security/key.jks" 
    password="changeit" /> 
<keyStore id="defaultTrustStore" 
    location="${server.config.dir}/resources/security/trust.jks" password="changeit" />
