wso2 esb 在 soap 到 rest 转换期间的意外行为
Unexpected behavior from wso2 esb during soap to rest conversion
我已经使用 WSO2 ESB 构建了一个代理服务，我想用它来将 REST 网络服务（来自某个随机供应商）作为 SOAP 网络服务公开给另一个随机供应商。我遇到的问题是其中一种肥皂方法根本不起作用。有问题的方法是 "myVendorBpmInsereCliente"。我发现真正令人困惑的是方法 "myVendorBpmAtualizaCliente" 几乎是一样的东西确实有效！我收到错误代码 405（http 响应代码），因为 属性 中介 "REST_URL_POSTFIX" 似乎没有将其余路径附加到 uri。

在另一次尝试中，我添加了一个自定义日志中介来记录表达式的值：$axis2:REST_URL_POSTFIX，结果是我所期望的："cliente/novo?chave=myKey"。请注意，出于说明目的，我更改了序列中的端点。我使用 WSO2 ESB 版本 4.6.0，运行 作为服务。有什么建议吗？
能否请您将端点格式更改为 rest 并检查是否可以解决问题。
