调用函数时Web服务出错 [英] Error in a Webservice when a function is call

问题描述

在http：// localhost：999 / DE.Web / WCFServices / DE_Service.svc上没有可以接受该消息的端点。这通常是由错误的地址或SOAP操作引起的。有关详细信息，请参阅InnerException（如果存在）。



确定

There was no endpoint listening at http://localhost:999/DE.Web/WCFServices/DE_Service.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

OK

推荐答案

错误消息本身表明Web服务存在一些问题通信（配置问题或连接问题）。



- >通过查看您的网址首先确认您是从服务所在的同一台计算机访问服务。如果不是这种情况，因为localhost存在于URL中，请使用正确部署服务的IP地址或计算机名称更改localhost。 （愚蠢的建议，但可能是个问题）。



- >第二件事请确认网址是否正确，并且您配置的网址没有问题您的浏览器。



- >第三件事是尝试访问 http：// localhost：999 / DE.Web / WCFServices / DE_Service.svc [ ^ ]服务从哪里运行你的代码通过在浏览器中粘贴上面的URL。



如果失败那么你的服务没有处于运行模式。



请检查以上步骤，如果仍未运行，则服务和消费者应用程序之间可能存在连接问题





希望它有帮助。

The Error Message itself depicts that there is some problem in web service communication(configuration problem or connection problem).

-->By seeing your url first confirms that you are accessing service from the same machine where your service is located. as localhost is present in URL if that is not the case then please change localhost with the ip address or machine name where exactly your service is deployed. (silly suggestion but might be a problem).

-->Second thing please verify that URL is correct and there is no problem with the URL u had configured in your browser.

--> Third thing try to access the http://localhost:999/DE.Web/WCFServices/DE_Service.svc[^] service from where u are runnning your code by pasting above url in your browser.

if it fails then your service is not in running mode.

Please check above steps and if it still not running then there might be some connection issue between service and consumer application


Hope it helps.
