WCF访问被拒绝异常

Question

尝试运行WCF服务时出现以下情况。我已尝试了页面http://msdn.microsoft.com/en-us/library/ms733768.aspx上与netsh相关的建议，但没有任何作用。请提供帮助，告诉我如何解决这个问题。谢谢！

Answer 1

两种选项（可以任选其一）

1.使用netsh实用程序提供对端口的访问

netsh http add urlacl url=http://+:8439/ user=DOMAIN\UserName

2.需要管理员权限

以管理员身份运行（Visual Studio或应用程序本身）

我已经尝试了第一个方法。虽然尝试成功了，但并没有解决问题。然而，当我尝试使用第二个方法时，现在出现了不同的异常信息***{"URI 'http://127.0.0.1:8439/'已存在注册。"}***。 - user272671

使用以下命令：netsh http delete urlacl url=http://+:8439 ... - Tilak

我已经删除了它，但异常 *** A Registration already exists for URI** 仍然存在。 - user272671

执行 "netsh http show urlacl" 命令，并检查是否已经存在 8439 的条目。 - Tilak

刚刚检查了一下，似乎没有此端口号的先前注册记录。 - user272671
