Question

I ve written a ColdFusion Web Service for an external client to consume. It basically let s them send over some user information, and returns the contents of the user s shopping cart, and let s them add items to the user s shopping cart. For simplicity sake, we ll just cover the "getCart" method.

他们需要网络服务局将Xml送回SOAP信封,但还需要Xml控制具体的复杂数据类型。例如,每一项请求都需要作为<代码>ReturnInfo类型的一部分,归还身份代码和电文。因此,我写了一份硬编码的WSDL,供他们用内部概述的复杂数据类型消费(我基本上采用由冷战产生的WSDL,并编辑):

他们对网络服务的每一电话给他们同样的错误:

我不十分熟悉SOAP,也不熟悉CF中的复杂数据类型,因此,这里的迷魂药。我的《家庭法》:

Answer 1

这可能是一些事情,但最常见的被忽视原因是:

您改变了该方法的签字(功能参数、类型、论点数目、返回类型等),但冷静反应了障碍。

<>Solution

戈到冷静的署长,在“数据与计划”下,在“服务”和“网络服务”下,发现“URL”,包括“WSDL”,要么更新,要么完全删除。

也许不是你的具体解决办法,而是合理的起点。

Answer 2

如果你没有机会接触CF署长,需要更新网络服务;你可以建立一个网页,更新网站服务。包括这两行:

<cfobject action="CREATE" type="JAVA" class="coldfusion.server.ServiceFactory" name="ServiceFactory">
<cfset ServiceFactory.getXMLRPCService().refreshWebService("http://cart.ws?WSDL")>

最后一行有一个需要更新的网络服务网吧。
