WCF--提示:"未找到终结点。"

2023-02-19 08:15:47

刚开始调用WCF的时候一直报错...

““System.ServiceModel.EndpointNotFoundException”类型的异常在 mscorlib.dll 中发生，但未在用户代码中进行处理”

“其他信息: 没有终结点在侦听可以接受消息的 http://xx.xx.xx.xx:端口//Service1.svc。这通常是由于不正确的地址或者 SOAP 操作导致的。如果存在此情况，请参见 InnerException 以了解详细信息。”

点开详细信息：“InnerException:{"远程服务器返回错误: (404) 未找到。"}”

浏览器打开http://xx.xx.xx.xx:端口//Service1.svc/IService1/GetInfoByID

页面显示:“”未找到终结点。”

由此可见，是服务的问题了...

吾本以为简单的一个问题，搜一下，答案便可出矣...哀哉悲哉...折腾过来折腾过去，没毛线进展...

只好自己一步一个脚印来深入研究之，正好学习下...

了解的过程修改过来修改过去...

最终···得出一个结论...

不是IIS的问题就是web.config文件的配置问题...

最后一狠心...

将web.config全部删了...

抄来了一个完好的例子

...莫名其妙的好了...

现在是后台"添加服务引用"之后是可以调用服务了...

下一步还要解决.要前台ajax可以调用的方法...

支持 Ajax(只能算是一个折中的解决方案...No Pre)
