ColdFusion 2021 返回“对象不是声明类的实例”

编程问答 2022-05-29

问题描述

我们正在将 ColdFusion 服务器从 2016 版升级到 2021 版。以下代码在 2016 年有效，但在 2021 版中给出“对象不是声明类的实例”：

Application.UserWebService = CreateObject("webservice",Application.Settings.ws_url & "Requests/UserService.asmx?WSDL",oWsdlArgs);
addSOAPRequestHeader(Application.UserWebService,"",objSoapHeader,true);

Application.WhiteLabelService = CreateObject("webservice",Application.Settings.ws_url & "Requests/WhiteLabelService.asmx?WSDL",oWsdlArgs);
addSOAPRequestHeader(Application.WhiteLabelService,true);

Application.EmailService = CreateObject("webservice",Application.Settings.ws_url & "Requests/EmailService.asmx?WSDL",oWsdlArgs);
addSOAPRequestHeader(Application.EmailService,true);

// This struct is to be added as the last parameter in all WebService calls which require a LanguageHeader
Application.LanguageHeader = structNew();
Application.LanguageHeader.locale = "en-CA";

// Get the .Net resources
Application.NetResources = Application.UserWebService.GetNetResources(Application.LanguageHeader); 

// Initialize resource manager
createObject("component","#Application.GlobalComponentPath#ResourceManager").init(Application.Settings.defaultBaseCategory);

在调用 GetNetResources() 时发生错误。

当调用重新排序时，首先创建和初始化 LanguageHeader，错误消失：

// This struct is to be added as the last parameter in all WebService calls which require a LanguageHeader
Application.LanguageHeader = structNew();
Application.LanguageHeader.locale = "en-CA";

Application.UserWebService = CreateObject("webservice", Application.Settings.ws_url & "Requests/UserService.asmx?WSDL", oWsdlArgs);
addSOAPRequestHeader(Application.UserWebService,true);

// Get the .Net resources
Application.NetResources = Application.UserWebService.GetNetResources(Application.LanguageHeader); 

Application.EmailService = CreateObject("webservice", Application.Settings.ws_url & "Requests/EmailService.asmx?WSDL", oWsdlArgs);
addSOAPRequestHeader(Application.EmailService, "", objSoapHeader, true);

Application.WhiteLabelService = CreateObject("webservice", Application.Settings.ws_url & "Requests/WhiteLabelService.asmx?WSDL", oWsdlArgs);
addSOAPRequestHeader(Application.WhiteLabelService,true);

// Initialize resource manager
createObject("component", "#Application.GlobalComponentPath#ResourceManager").init(Application.Settings.defaultBaseCategory);

我们无法确定发生这种情况的原因。 CF 管理 Web 服务的方式是否发生了变化？是否有需要修改的设置？

谢谢！
