IBM集成总线：SOAP请求收到HTTP错误状态代码“500”

Question

我是Ibm集成总线的新手，一直在努力将数据从http节点转换为SOAP节点。我的消息流

问题是，当我使用SOAP输入时，它可以工作，但当我使用Http输入更改它并将数据从JSON转换为XML时，错误不断出现。

计算节点代码：

     DECLARE reftoOut REFERENCE To OutputRoot.XMLNSC.ns2:MessageExtraitRequest;
     DECLARE reftoIn REFERENCE To InputRoot.JSON.Data;
        
        
        SET reftoOut.ns2:No_du_compte = reftoIn.No_du_compte;
        SET reftoOut.ns2:Date_operation = reftoIn.Date_operation;
        SET reftoOut.ns2:REFERENCE = reftoIn.REFERENCE;
        SET reftoOut.ns2:Libelle = reftoIn.Libelle;
        SET reftoOut.ns2:Date_valeur = reftoIn.Date_valeur;
        SET reftoOut.ns2:DEBIT = reftoIn.DEBIT;
        SET reftoOut.ns2:CREDIT = reftoIn.CREDIT;

我的WSDL（它与SOAPInput和postman配合得很好）

Answer 1

错误消息的重要位包括：

BIP3754E: The SOAP Request Node or SOAP Async Request Node WS_MF
          encountered an error while processing the outbound SOAP request.

BIP3711E: A SOAP request received an HTTP Error Status Code '500',
          but the response message body was not a SOAP fault.

换句话说：endpoint的回复<代码>http://localhost:8000/wsdl不是有效的SOAP回复；可能是纯文本。您应该分析这个endpoint，并找出它为什么没有回复正确的SOAP回复。
