在 iPhone 上使用 Objective-C 使用 WCF Web 服务 [英] Consume WCF Web Service using Objective-C on iPhone
问题描述
我很难在我的 iPhone 应用程序中使用一个非常简单的(Hello World)WCF Web 服务.根据我的阅读,您必须手动创建请求消息,然后将其发送到 Web 服务 URL.
I am having a hard time consuming a very simple (Hello World) WCF web service in my iPhone app. From what I have read, you must manually create the request message then send it to the web service URL.
我能够在 .asmx Web 服务上完成此操作,但无法使用 WCF 服务.
I was able to accomplish this on a .asmx web service, but not with a WCF service.
我如何知道请求 SOAP 消息的正确格式?
How do I know the correct format of the request SOAP message?
我尝试访问的 Web 服务的格式为:http://xxx.xxx.xxx.xxx:PORT/IService1/ (在虚拟机中本地运行)
The web service I am trying to hit has a format of: http://xxx.xxx.xxx.xxx:PORT/IService1/ (running locally in a VM)
我很抱歉缺乏信息,我很迷茫.
I apologize for the lack of information, I am pretty lost.
非常感谢任何和所有帮助.
Any and all help is much appreciated.
