WSO2自定义处理程序可处理JSON数据

Question

在自定义WSO2处理程序上编写代码后，我的服务将使用JSON进行工作。 试图让处理程序读取JSON数据

如何从WSO2 ESB Synapse处理程序内的REST请求的JSON正文提取数据的解决方案不起作用

处理程序代码

@Override
public boolean handleRequest(MessageContext messageContext) {

    System.out.println("getEnvelope - "+ messageContext.getEnvelope().getBody().toString());

    org.apache.axis2.context.MessageContext mc = ((Axis2MessageContext) messageContext).getAxis2MessageContext();
    JSONObject jsonBody = new JSONObject(JsonUtil.jsonPayloadToString(mc));
    System.out.println("Payload in json -"+ jsonBody);

    String jsonPayloadToString = JsonUtil.jsonPayloadToString(((Axis2MessageContext) messageContext).getAxis2MessageContext()); 
    System.out.println("Payload in string -"+ jsonPayloadToString);

控制台输出

getEnvelope - <soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"/>                                                                                                                      
Payload in json -{}                                                                                                                                                                                          
Payload in string -{}   

尝试了axis2.xml中的所有3种三种组合

        <messageBuilder contentType="application/json"
                        class="org.apache.axis2.json.JSONOMBuilder"/>
        <!--messageBuilder contentType="application/json"
                        class="org.apache.synapse.commons.json.JsonStreamBuilder"/-->
        <!--messageBuilder contentType="application/json"
                        class="org.apache.synapse.commons.json.JsonBuilder"/-->
-----------------
        <messageFormatter contentType="application/json"
                          class="org.apache.axis2.json.JSONMessageFormatter"/>
        <!--messageFormatter contentType="application/json"
                          class="org.apache.synapse.commons.json.JsonStreamFormatter"/-->
        <!--messageFormatter contentType="application/json"
                          class="org.apache.synapse.commons.json.JsonFormatter"/-->

任何帮助都会有很大帮助

谢谢

尝试RelayUtils.buildMessage(messageContext); 在打印主体之前。

Answer 2

为您的json尝试以下代码：

try {

            RelayUtils.buildMessage(((Axis2MessageContext) messageContext).getAxis2MessageContext());
        } 
    catch (XMLStreamException e) {
            e.printStackTrace();
        }
     catch (IOException e1) {
        e1.printStackTrace();
    }

    String body = JsonUtil.jsonPayloadToString(((Axis2MessageContext) messageContext).getAxis2MessageContext());
    String httpMethod = (String) ((Axis2MessageContext) messageContext).getAxis2MessageContext().getProperty("HTTP_METHOD");
    System.out.println("\n\nWSO2CustomHandler - handleRequest body!!" + body);
    System.out.println("\n\nWSO2CustomHandler - handleRequest httpMethod!!" + httpMethod);
