在wso2 api管理器的自定义处理程序中获取GET类型rest api的空体

Question

我在soap主体中的响应有效负载是empty.Below，它是在api manager中配置的自定义处理程序代码。我打印了正文，它显示了empty.My rest api应该返回的数据列表。

public boolean handleResponse(MessageContext messageContext)
 {
try {

            RelayUtils.buildMessage(((Axis2MessageContext) messageContext).getAxis2MessageContext());
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XMLStreamException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

 log.info("Response Body:"+messageContext.getEnvelope().getBody());
}

如果API的响应状态为OK，但如果为ACCEPT状态，则响应正文为空。

This is my logs after enabling the wire. Please help. Thanks in advance.

Answer 1

根据您的问题，您是说当后台响应202代码时，响应body为空，当后台响应代码为200时，您可以从上面的代码逻辑访问后台响应。首先，当http代码为202时，您必须检查响应正文是否来自后端。为此，您可以为wso2 apimanager启用连接日志，如1所示，并检查后端响应。
