如何使用脚本调解器将 JSON 数组响应转换为 esb wso2 中的 xml 数组答案

【问题标题】：How to transform JSON array response to xml array in esb wso2 using script mediator如何使用脚本调解器将 JSON 数组响应转换为 esb wso2 中的 xml 数组
【发布时间】：2017-12-02 16:12:49
【问题描述】：

我在我的 ESB 中获得 JSON 数组响应，但我需要使用脚本中介将其转换为 XML。 JSON 数组响应的长度是动态的。我需要遍历整个 JSON 数组长度并将其转换为 xml。请帮忙。

以下是我现在得到的 JSON 数组响应，但长度不固定。

您可以使用 Jackson Plugin 实现此目的，非常简单快捷
我在 ESB WSO2 中进行转换，所以我将不得不使用脚本中介。
好吧...我只是不知道
最好使用XSLT...1-从json转换为xml，2-创建xslt转换并在esb中使用。
因为，我有 json 数组，所以我将不得不使用脚本中介。我已经编写了脚本中介代码，但现在我收到错误，因为“脚本引擎返回执行内联 js 脚本的错误函数调解 {org.apache.synapse.mediators.bsf.ScriptMediator} com.sun.phobos.script.util.ExtendedScriptException: org.mozilla.javascript.EcmaError: TypeError: Cannot read property "length" from undefined ( #4) 在的第 4 行，com.sun.phobos.script.javascript.RhinoCompiledScript.eval(RhinoCompiledScript.java:68)"......你有什么想法吗？跨度>

【解决方案1】：

如果将messageType 属性添加到out 序列，它应该会自动将消息转换为XML。

<outSequence>
    <property name="messageType" value="application/xml" scope="axis2"/>
    <send/>
</outSequence>

我通过编写下面的代码让它工作了。

<script language="js"><![CDATA[
               var   payload = mc.getPayloadJSON();
   var results = payload.Results;
    var response = <locations/>;
    for (i = 0; i < results.length; ++i) {
        var elem = results[i];
        response.locations += <jacdevice>
            <JACDeviceId>{elem.Id}</JACDeviceId>
            <Make>{elem.ManufacturerName}</Make>
            <Model>{elem.ModelName}</Model>
        </jacdevice>
    }
    mc.setPayloadXML(response);
                ]]></script>
