我有一个简单的talend作业（数据集成），它使用tRest组件使用我们内部网络外部的GET请求连接到休息服务。这适用于通用http URL，但在使用任何https URL时，作业会“挂起”一段时间，然后出现以下错误： -

这似乎发生在我尝试的任何https端点上。所涉及的URL可通过同一台机器上的浏览器访问。
有关原因的任何想法？我确保所涉及的根证书都在jre的cacerts文件中，但我认为它没有那么远。
答案 0 :(得分：0)
使用 tSetKeystore 组件，您应该能够设置tRest组件。如果需要，您可以在 tSetKeystore 组件中输入信任库和密钥库。然后使用 OnComponentOk 连接触发您的tRest访问该网址。
答案 1 :(得分：0)
您需要在{JAVA_HOME} /../ jre / lib / security / cacerts中拥有受信任的根证书。
通过列出添加的证书来确保已将证书添加到cacert。
重新启动Open Studio，然后重试。
