项目阶段：评估 ESB。

我们曾考虑将 WSO2 作为 ESB 解决方案，但遇到了许多问题。

目前我正在尝试让一个简单的 WSDL 代理服务正常工作，但没有成功。

这些是我做的事情

  • 创建了一个基于 WSDL 的代理
  • 点击“试用此服务”
  • 填写参数（邮编）
  • 点击发送

响应如下

<TryitProxyError h:status="SOAP envelope error" xmlns:h="http://wso2.org/ns/TryitProxy">**org.apache.axis2.AxisFault: Transport error: 411 Error: Length Required**</TryitProxyError>

您的后端 Web 服务器是否支持 HTTP/1.1？如果没有，那么这可能就是这里的问题。因为，最新版本的 WSO2 ESB，默认使用 HTTP/1.1 进行 Web 服务通信。在 HTTP/1.1 中，它默认使用分块的 Transfer-Encoding 响应标头代替 HTTP/1.0 的 content-length 标头。因此，您可能希望禁用分块响应或强制通过 HTTP/1.0 发送消息。

将以下属性添加到您的 ESB 代理服务配置将禁用分块。

<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>

希望能帮助到你！
