在 uri-template 中使用 uri.var 参数时,WSO2ESB HTTP Endpoint 抛出异常 [英] WSO2ESB HTTP Endpoint throws exception when using uri.var parameters in the uri-template
问题描述
我尝试使用以下配置调用 REST 端点:
I tried to invoke a REST endpoint by using the following configuration:
...
<property name="uri.var.host" value="localhost:8080"/>
<property name="uri.var.context" value="my-service"/>
<call>
<endpoint>
<http method="POST" uri-template="http://{uri.var.host}/{uri.var.context}" />
</endpoint>
</call>
...
但随后我收到一个 XMLStreamException,显示不允许使用 DOCTYPE":
But then I get an XMLStreamException that says "DOCTYPE is not allowed":
[2016-06-01 17:16:15,702] ERROR - RelayUtils Error while building Passthrough stream
org.apache.axiom.om.OMException: javax.xml.stream.XMLStreamException: DOCTYPE is not allowed
...
另一方面,如果我不使用 uri.var 参数,它可以正常工作,即此配置有效:
On the other hand, it works without any issues if I don't use uri.var parameters, i.e. this configuration works:
...
<call>
<endpoint>
<http method="POST" uri-template="http://localhost:8080/my-service"/>
</endpoint>
</call>
...
不幸的是,我需要使用 uri.var 参数,因为需要动态指定目标端点.所以问题是如何使 uri.var 参数起作用?谢谢!
Unfortunately, I need to use uri.var parameters since the target endpoint needs to be specified dynamically. So the question is how can I make uri.var parameters to work? Thanks!
推荐答案
如果您启用了线路日志,您可以找到您所指的实际端点.请参阅下文 示例请求.
If you enable the wirelog you can find what is the actual endpoint you are referring.see below sample request.
<property name="uri.var.username" expression="$func:username"/>
<call>
<endpoint>
<http method="get" uri-template="{+uri.var.apiUrl}/users/{+uri.var.username}/orgs"/>
</endpoint>
</call>
