我正面临REST API中序列外的一些问题。我的用例是,我将接收json请求,调用一个服务,如果成功,则调用第二个服务。现在我跳过了对第一服务响应的检查。在inSequence中有一个端点,在outSequence中有另一个端点。问题是在outSequence中,它进入了无限循环。
请让我知道我错过了什么。

您需要从out序列中删除以下内容。在ESB中,当接收到响应时,它将触发结果序列,因此您看到的是无限循环。可以在序列中使用调用中介而不是发送中介来避免这种情况。
<send>
<endpoint>
<address format = "rest" trace = "disable" uri = http://10.202.17.86:8085/UserInfo/rest/v1/login"/>
</endpoint>
</send>
下面是一篇很好的文章来涵盖你的用例。
http://wso2.com/library/articles/2014/02/service-orchestration-with-wso2-esb/感谢您的回复。我不确定,但是当我使用Call mediator时,服务调用不会发生。但是Send中介可以工作。我能够解决这个问题,无论是在inSequence和outSequence相同的url。我更改了outSequence的URL,现在工作正常
