我尝试在WSO2 ESB中同时使用代理和API来测试类似SOAP Web服务的聚合到一个响应中，但我只是暂停了。为了测试，我使用了天气网络服务（http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl）。我基本上通过使用克隆介体为每个提供不同的邮政编码调用相同的操作GetCityWeatherByZIP，然后聚合结果。事件的目的是调用托管在不同服务器上的Web服务，但目前我正在尝试使用相同的服务。我很感激能得到的任何帮助。
以下是代理配置：
<?xml version="1.0" encoding="UTF-8"?>

<m0:ZIP>11001</m0:ZIP>

SOAP Action不正确，必须是http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP
聚合的onComplete xpath表达式的命名空间不正确，最后缺少'/'：http://ws.cdyne.com/WeatherWS/
汇总后，您不想删除邮件，而是希望将其作为回复发送：将<drop/>替换为“onComplete”中介中的<send/>
响应将是一个soap消息，SOAP Body必须有一个根节点作为第一个子节点，因此您必须应用转换，例如：
<payloadFactory media-type="xml">
<format>
<response>
$1
</response>
</format>
<args>
<arg evaluator="xml" xmlns:m0="http://ws.cdyne.com/WeatherWS/" expression="//m0:GetCityWeatherByZIPResponse"/>
</args>
</payloadFactory>
默认情况下，克隆介体停止父调解，如果要执行聚合，则需要指定continueParent="true"
使用调用中介，下划线工作线程返回而不等待响应：用于执行代理的请求将到达聚合：在执行聚合中介之前，测试消息是否为GetCityWeatherByZIPResponse

call mediator依赖于非阻塞传输：编辑repository / conf / nhttp.properties并添加 如果您同意等待60秒， http.socket.timeout.sender = 60000
