【问题描述】：
当我尝试在blocking="true" 的序列中使用调用中介时，它会在发送中介正常工作时引发错误。有人可以指出我错在哪里。
我正在使用 WSO2 APIM 2.6.0
代码：
<call blocking="true">
<endpoint>
<http method="get" uri-template="http://10.10.10.10:10/XYZ/rest/1.0/abc/{uri.var.userId}"/>
</endpoint>
</call>
<respond/>
我收到以下错误消息：
INFO {org.apache.axis2.transport.http.HTTPSender} - Unable to sendViaGet to url[http://10.10.10.10:10/XYZ/rest/1.0/abc/USERX] {org.apache.axis2.transport.http.HTTPSender}

【问题讨论】：
-
这是一个 404。似乎我们的 URL 错误。
-
如果我替换 Send 而不是 Call 它可以工作。我无法确定为什么 call 会出现 404 错误。
