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，我一直在努力将数据从 http 节点转换为 SOAP 节点。 My message Flow

问题是当我使用 SOAP 输入时它可以工作，但是当我使用 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 和邮递员配合得很好）

Answer 1

错误消息的重要部分是：

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：端点http://localhost:8000/wsdl的回复不是有效的SOAP回复；也许它是纯文本。您应该分析这个端点并找出它为什么没有回复正确的 SOAP 回复。
