WSO2：ESB：将接收的非SOAP格式的数据传递到序列失败

Question

我有一个REST API（简称为MYTESTAPI1），该API会为某些数据调用第三方API。第三方API以以下格式返回数据。

调用后，在上述API中调用新序列时，它可以正常工作。

<wd:Report_Data xmlns:wd="Project_Export">
<wd:Report_Entry>
<wd:referenceID>PR00001</wd:referenceID>
<wd:projectName>
Test Project1
</wd:projectName>
<wd:Inactive>0</wd:Inactive>
<wd:Cost_Center_group>
<wd:Cost_Center_ID>CG1</wd:Cost_Center_ID>
</wd:Cost_Center_group>
<wd:Research_Budget_Remaining>0</wd:Research_Budget_Remaining>
<wd:Currency wd:Descriptor="AUD">
<wd:ID wd:type="WID">8a96ee707a264afe888d90ef93253305</wd:ID>
<wd:ID wd:type="Currency_ID">AUD</wd:ID>
<wd:ID wd:type="Currency_Numeric_Code">036</wd:ID>
</wd:Currency>
</wd:Report_Entry>
</wd:Report_Data>

但是，当我从另一个代理服务（位于另一个CAR文件中）调用MYTESTAPI1 REST API时，它将给出以下异常。任何帮助都会非常有帮助。如果我不返回结果就返回结果，则不会给出错误。

Answer 1

我相信您正在使用地址端点。请切换到HTTP端点以解决此问题。

Answer 2

似乎该消息正在尝试使用SOAP构建器构建。为避免此问题，可以尝试将messageType属性设置为合适的值。 （例如：application / xml）

尝试在调用序列之前添加此属性。

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