Java HttpClient NoSuchAlgorithmException

Question

我正在使用 IBM 的 Java 版本和 HttpClient，但收效甚微。每当我使用 HttpClient 对象的executeMethod() 时，我都会收到NoSuchAlgorithmException。

Dec 22, 2009 2:59:58 PM com.ibm.rcp.security.ssl.PlatformSSLProtocolSocketFactory createPlatformSSLContext()
WARNING: CWPST502W:  The algorithm for recovering the key from the keystore cannot be found.

Answer 1

您似乎正在尝试使用 HTTPS，并且需要额外的工作才能使加密扩展正常工作。

与常规浏览器不同，http 客户端不太了解如何使用证书，您可能必须自己添加它才能正常工作。

另一种可能性是您尝试使用客户端中不支持/安装的加密提供程序。
