在wso2 api manager的自定义处理程序中为GET类型的rest api获取空体

时间：2016-10-05 12:03:01

标签： wso2-am

我在soap body中的响应有效负载是空的.Below是在api manager中配置的自定义处理程序代码。我打印了正文，它显示为空。我的休息api应该返回数据列表。

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的响应状态正常，它的工作正常，但在ACCEPT状态下，响应正文为空。

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

根据你的问题，你说当后端用202代码响应时响应体是空的，当后端响应代码是200时，你可以从上面的代码逻辑中访问后端响应。首先，当http代码为202时，你必须实际检查响应主体是否来自后端。为此你可以启用[1]中的有线日志，用于wso2 apimanager并检查后端响应。
