我有一个代理服务可以在多个系统中搜索用户,并且应该返回 JSON 格式的组合响应。我得到了组合的响应,但我得到的不是 JSON 格式的响应,而是 XML 格式的响应。 我可以在 WSO2 服务器日志中看到 JSON 响应,如下所示:
[2016-07-19 07:26:58,249] INFO - LogMediator To: http://www.w3.org/2005/08/addr

}

但是,我在调用代理 url 后没有收到 JSON 格式的响应。 下面是我的 ESB 配置:
<?xml version="1.0" encoding="UTF-8"?>

我得到如下响应:

请告诉我如何获得 JSON 响应。 任何帮助将不胜感激。
最佳答案
可以在outSequence中设置messageType为application/json而不是application/xacml+json试试。
<property name="messageType" value="application/json" scope="axis2" type="STRING" description="messageType"/>
此外,默认情况下,WSO2 ESB 不附带 application/xacml+json 消息格式化程序和消息构建器。如果您需要使用这些格式,您必须编写自己的格式化程序和构建器,并在 axis2.xml 文件中配置它们。
关于json - 在 WSO2 ESB 中聚合后无法获得 JSON 格式的响应,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/38457557/
