它之前工作得很好，但现在我使用相同的文档作为POST方法发送另一个安静的服务，它抛出以下错误

这是APIM 1.7中的一个已知问题，它为多根JSON消息添加了额外的xmlPayload元素。这是由于Jettison库中的一个错误，它是APIM 1.7中的默认json消息解析器。您可以通过修改axis2.xml文件来更改消息构建器和格式化程序来消除此错误，如下所示;

在APIM 1.7的axis2.xml中为application/json类型添加以下构建器和格式化程序（注释掉现有的消息构建器和“application / json”类型的格式化程序）

<messageFormatter contentType="application/json"
                  class="org.apache.synapse.commons.json.JsonStreamFormatter"/>


<messageBuilder contentType="application/json"
                class="org.apache.synapse.commons.json.JsonStreamBuilder"/>

在WSO2 API1.7中POST POST restful service request时发出问题
