我创建了以下 WSO2 数据服务器服务。

   <data name="Codelists" serviceGroup="test group" serviceNamespace="********">

   </data>

我想通过 wso2 ESB 使用这个服务。但是我无法让它工作。我应该如何在 ESB 中公开服务以及我应该应用什么类型的安全性？你能给我一些参考指南吗？

我尝试了以下 ESB 配置：

<proxy name="Codelists" transports="https" startOnLoad="true" trace="disable">
    <target>
        <endpoint>
            <address uri="http://localhost:9446/services/Codelists"/>
        </endpoint>
        <outSequence>
            <send/>
        </outSequence>
    </target>
    <publishWSDL uri="https://localhost:9446/services/Codelists?wsdl"/>
    <policy key="conf:/repository/axis2/service-groups/Codelists/services/Codelists/policies/UTOverTransport"/>
    <enableSec/>
</proxy>

但是，当我使用“TryIt”功能时，使用此配置，我会收到授权错误或以下情况：

    [2012-08-02 10:03:50,966]  WARN - ClientHandler I/O error : Connection reset by peer For : 127.0.0.1:9446 For Request : Axis2Request [Message ID : urn:uuid:57d99ccc-9dde-428b-bfdb-73f87276a491] [Status Completed : false] [Status SendingCompleted : true]

  • 检查是否可以使用 dataservices tryit ui 尝试创建的数据服务。
  • 如果是这样，您可以简单地创建一个直通代理（不启用安全性）并尝试通过 ESB 调用相同的服务。
  • 如果您想将该代理服务公开为安全服务，您可以简单地启用安全性并从 16 个可用的安全方案中选择一个合适的安全方案。
