Question

我有一个带有HTTPS入站请求/响应的流，它接受带有XML数据的帖子（端口8081）。我对数据进行了一些处理，然后想要通过443执行另一个HTTPS帖子到不同的URL，以便数据由外部进程（PeopleSoft IB）处理。

问题在于，当我尝试发布到HTTPS：443 outbound从HTTPS传入的内容：8081入站时，我收到如下所示的错误。

但是，如果我将入站连接器设置为HTTP且不是 HTTPS并注释掉https：连接器名称=＆＃34; httpsConnector＆＃34;我有设置，一切都很完美，我可以发布到HTTPS / 443端点。

我已经搜索过高低，尝试了很多不同的事情来尝试解决这个错误，但到目前为止所有的尝试都失败了。我知道它与有效载荷有关，因为MuleSoft正在跟踪并且从不路由到HTTPS端点。我通过将有效负载更改为纯文本并且已成功发送来确认了这一点。它也像我上面提到的那样成功发送，当我以HTTP到8081进入入站时。

我是MuleSoft的新手，所以如果这是一个简单的解决方案，请原谅我的无知。

Answer 1

对于所有好奇的人来说，这个问题归结为为密码库配置了适用于HTTPS出站端点的证书。这是在MuleSoft支持的帮助下发现的。

如何做到这一点是：

将log4j.logger.httpclient.wire = DEBUG添加到log4j.properties，然后将此文件添加到src / main / resources（我在本地运行）
从HTTPS出站连接器中删除localhost作为代理

这显示了跟踪中的以下内容，清楚地显示了问题所在。

+ 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

我以前没有与HTTPS出站连接器关联的密钥库（我使用入站连接），因为当我以HTTP身份进入，然后以HTTPS身份出现时，不需要。我发现，经过很多痛苦后，需要一个密钥库，入站为HTTPS，出站为HTTPS。

在这个出站HTTPS密钥库中，我添加了网站的证书（PeopleSoft集成代理的监听连接器），一切都很顺利。

Answer 2

我从未见过这个确切的错误，但我想我知道什么可以提供帮助。尝试在https入站端点后添加对象到字符串转换器。

Mule - 无法通过HTTPS端点路由
