如何使用Mule中的HTTP連接器刷新請求中的xml數據

[英]How to flush xml data in request by using HTTP connector in mule

我正在使用Java組件發送請求,它對我來說工作正常。 代碼是。

 public class parseXmlToString implements Callable 
    {
        public Object onCall(MuleEventContext eventContext) throws Exception 
        {
            String xmlData = eventContext.getMessage().getInvocationProperty("sampleXmlData");
            String content = URLEncoder.encode(xmlData, "UTF-8");
            eventContext.getMessage().setInvocationProperty("xmlData", content);

            try
            {
                URL url = new URL(webServiceURL);
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();

                conn.setDoInput(true);
                conn.setDoOutput(true);
                conn.setUseCaches(false);
                conn.setRequestMethod("POST");
                conn.connect();

                DataOutputStream output = null;
                output = new DataOutputStream(conn.getOutputStream());

                String content = "xmlData=" + URLEncoder.encode(xmlData, "UTF-8");

                output.writeBytes(content);
                output.flush();
                output.close();

                if (conn.getResponseCode() != 200) 
                {
                    System.out.println(conn.getResponseCode());
                    throw new IOException(conn.getResponseMessage());
                }

                BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                StringBuilder sb = new StringBuilder();
                String line;
                while ((line = rd.readLine()) != null) 
                {
                    sb.append(line);
                }

                rd.close();
                conn.disconnect();
                eventContext.getMessage().setPayload("Import Initiated");
            }
            catch (Exception e)
            {
                System.out.println("Failed REST service call. " + e.getMessage());
                e.printStackTrace();
            }
            eventContext.getMessage().setPayload(content);
            return eventContext.getMessage().getPayload();enter code here
        }

    }

現在,我試圖通過在HTTP子中使用HTTP連接器發送請求,為此,我正在使用請求參數發送數據。 的代碼是

<http:request config-ref="HTTP_Request_Configuration1" path="/#flowVars.outputAppName]/services/EmployeeService/importUsers" method="POST" doc:name="HTTP" parseResponse="false">
<http:request-builder> 
<http:query-param paramName="serviceId" value="#[flowVars.outputServiceID]"/>
<http:query-param paramName="expiresOn" value="#[flowVars.expiresOnImport]"/>
<http:query-param paramName="importId" value="#[flowVars.importId]"/>
<http:query-param paramName="signature" value="#[flowVars.signatureImport]"/>
<http:header headerName="xmlData" value="#[flowVars.xmlData]"/>
</http:request-builder>
 </http:request>

如果我運行它,則出現以下錯誤

    ERROR 2015-03-09 11:03:31,251 [[catalystoneconnector].HTTP_Listener_Configuration.worker.01] org.mule.exception.DefaultMessagingExceptionStrategy:

        + 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

我還嘗試過將XML數據作為查詢參數發送,就像http連接器中的其他參數一樣。 它也不起作用。

我做錯了什么,或者有任何適當的方法以M子的方式進行? 像在請求中發送大型xml嗎?

您需要將實體正文添加到POST請求中。 這是文檔中的示例:

<set-payload value="Hello world" />
<http:request request-config="HTTP_Request_Configuration"
      path="test" method="GET" sendBodyMode="ALWAYS"  />

因此,對於您的情況,您想要:

<set-payload value="#[flowVars.xmlData]"/>

<http:request config-ref="HTTP_Request_Configuration1"
      path="/#flowVars.outputAppName]/services/EmployeeService/importUsers"
      method="POST" parseResponse="false"
      sendBodyMode="ALWAYS">
  <http:request-builder> 
    <http:query-param paramName="serviceId" value="#[flowVars.outputServiceID]"/>
    <http:query-param paramName="expiresOn" value="#[flowVars.expiresOnImport]"/>
    <http:query-param paramName="importId" value="#[flowVars.importId]"/>
    <http:query-param paramName="signature" value="#[flowVars.signatureImport]"/>
  </http:request-builder>
</http:request>

我建議您查看一下提供的http路徑的定義,如下所示:/#flowVars.outputAppName]/services/EmployeeService/importUsers

您可以通過如下重新定義嘗試嗎
#['/'+flowVars.outputAppName+'/services/EmployeeService/importUsers']

@David建議使用set-payload組件設置xml數據,並使用所需的查詢參數集和http連接器方法=“ POST”定義http組件

不知道這是否有幫助,但是我正在尋找一種刷新xml數據的方法並進入了這個主題。 可能無法完全回答這個問題,但是如果有人像我一樣來這里尋找答案,我會遇到以下同樣的疑問:

從響應中刷新xml數據的一種方法是:

...使用Axis2 + SOAP 1.2

OMElement omElement = payloadTypeResponse.getOMElement(ServiceEMEStub.QueryData.MY_QNAME,OMAbstractFactory.getSOAP12Factory());
System.out.println(omElement.toString());
