WSO2 APIM:mc.setPayloadJSON 抛出 org.mozilla.javascript.WrappedException
WSO2 APIM:mc.setPayloadJSON throwing org.mozilla.javascript.WrappedException
我正在尝试使用 Javascript 在 WSO2 APIM 中操纵 JSON 请求并将其作为 application/json 发送。我修改了 axis2.xml & axis2_blocking_client.xml 以包括 JsonStreamFormatter 和 JsonStreamBuilder。设置 mc.setPayloadJSON 时得到 org.mozilla.javascript.WrappedException。
以下是代码片段和错误日志：

当我们调用mc.setPayloadJSON(newResponseJson);它尝试在消息上下文中构建现有的有效载荷，并在设置修改后的有效载荷之前将其转换为 XML 格式。转换由 StAXON 库 [1] 完成。
StAXON 在进行转换时将“@”字段视为 XML 中的属性。 [2] [3]
例如：
{"node": {"@attribute": "myAttrib"}} 表示为
关于 StAXON，您的有效负载中也存在两个问题，您也已经确定了。
- 它有以下带@字段的对象； StAXON 库不支持它，因为我们不能在 XML 属性中设置对象。
- @字段是在定义了JSON对象的普通字段后定义的("@timestamp": "2016-05-10T05:52:05.029Z")。 StAXON 也将此识别为问题。因为，在 XML 中，我们在开始定义它的 child/text 字段后没有指定属性。
为了缓解这个问题，我们需要避免构建现有消息并将其转换为 XML。为此，我们需要设置以下 属性 以在调用 mc.setPayloadJSON(newResponseJson);
之前从消息上下文中删除现有有效负载
mc.getEnvelope().getBody().getFirstElement().detach();

当我们调用mc.setPayloadJSON(newResponseJson);它尝试在消息上下文中构建现有的有效载荷，并在设置修改后的有效载荷之前将其转换为 XML 格式。转换由 StAXON 库 [1] 完成。 StAXON 在进行转换时将“@”字段视为 XML 中的属性。 [2] [3] 例如： {"node": {"@attribute": "myAttrib"}} 表示为 关于 StAXON，您的有效负载中也存在两个问题，您也已经确定了。
- 它有以下带@字段的对象； StAXON 库不支持它，因为我们不能在 XML 属性中设置对象。
- @字段是在定义了JSON对象的普通字段后定义的("@timestamp": "2016-05-10T05:52:05.029Z")。 StAXON 也将此识别为问题。因为，在 XML 中，我们在开始定义它的 child/text 字段后没有指定属性。
为了缓解这个问题，我们需要避免构建现有消息并将其转换为 XML。为此，我们需要设置以下 属性 以在调用 mc.setPayloadJSON(newResponseJson);
之前从消息上下文中删除现有有效负载mc.getEnvelope().getBody().getFirstElement().detach();
