WSO2：基于方法param的SOAP服务路由

我有一个简单的场景，我们一直在尝试实现，但我们不知道如何实现它

假设我们有两个带有dame WSDL的服务（如下）

我们希望在WSO2中创建一个代理，它公开相同的WSDL，但根据IntValue的值将调用路由到两个后端服务之一

IF IntValue = 1 THEN it calls
    http://localhost/WcfServiceDual_1/Service1.svc

ELSE IF IntValue = 2 THEN it calls
    http://localhost/WcfServiceDual_2/Service1.svc

之后，代理返回来自相应（被调用）服务的响应

为什么要托管同一服务的两个实例

无论如何，您计划在代理中使用的逻辑非常简单。从传入的请求中，只需提取要计算的参数，并根据该参数将请求路由到不同的端点。您可以使用解决此问题。

我找到了解决方案：
