传递给 Nav 2013 R2 的 SOAP 参数会导致错误，就好像它们为空一样

Question

我正在尝试使用自定义 SOAP 命令调用 Nav 2013 R2 Web 服务代码单元，但我收到一个响应，表明传递的参数为空，但事实并非如此。

有没有人知道为什么会发生这种情况，或者可以指出可以帮助解决此问题的方向？谢谢！

这是 SOAP 请求：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><TransferOrderCreate xmlns="urn:microsoft-dynamics-schemas/Codeunit/WebTestCodeunit"><ptext>this is some text</ptext><pint>999</pint></TransferOrderCreate></soap:Body></soap:Envelope>

这是 SOAP 响应：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><s:Fault><faultcode xmlns:a="urn:microsoft-dynamics-schemas/error">a:Microsoft.Dynamics.Nav.Service.WebMetadata.ServiceBrokerException</faultcode><faultstring xml:lang="en-CA">Parameter ptext in method TransferOrderCreate in service WebTestCodeunit is null! </faultstring><detail><string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">Parameter ptext in method TransferOrderCreate in service WebTestCodeunit is null! </string></detail></s:Fault></s:Body></s:Envelope>

这是 Nav 公开的服务：

检查 wsdl 定义中的名称空间和您的请求。命名空间区分大小写。

wsdl:

urn:microsoft-dynamics-schemas/codeunit/WebTestCodeunit

要求：

urn:microsoft-dynamics-schemas/Codeunit/WebTestCodeunit

这可能会引发您看到的异常。
