java - HttpClient 抛出 SSLException : Received fatal alert:decode_error

Question

我有一个在 Websphere 8.5 上运行的 Java 应用程序。我试图使用下面的代码调用第三方 Web 服务，但它失败了 SSLException，如下所示。

HttpClient httpClient = new HttpClient();
PostMethod post = new PostMethod(clientURL); 
post.addRequestHeader(....blah);    
httpClient.executeMethod(post);  // The error is thrown at this line `  

它失败并出现以下错误:

 HttpMethodDir I org.apache.commons.httpclient.HttpMethodDirector executeWithRetry I/O exception (javax.net.ssl.SSLException) caught when processing request: Received fatal alert: decode_error`   

下面是完整的堆栈跟踪:

Answer 1

我在这里猜测，但这里有一些可能性......

A:您应该在帖子 URL 中使用 http 而不是 https(反之亦然)

B:您正在使用 https 并且 SSL 证书无效

或者 C :您使用了正确的 URL 并且 SSL 有效，但您向 API 提供的身份验证无效并且第三方 API 没有很好地处理
