无法连接到Web服务器内置的Web开发人员-UnabletoconnecttoWebDevelopersbuiltinwebserver

Are you using Vista? I've had the same issues with recent Vista updates.

你在使用Vista吗?我最近的Vista更新遇到了同样的问题。

Firstly, make sure Visual Studio is running "As Administrator".

首先,确保Visual Studio正在“以管理员身份”运行。

Secondly, when the browser launches, replace "http://localhost:" with "http://127.0.0.1:". If that works, then its because a Windows Update messed up your hosts file.

其次,当浏览器启动时,将“http:// localhost:”替换为“http://127.0.0.1:”。如果可行,那么因为Windows Update搞砸了您的主机文件。

If this is the case, make sure you hosts file has this line in it, uncommented: "127.0.0.1 localhost"

如果是这种情况,请确保您的hosts文件中包含此行,取消注释:“127.0.0.1 localhost”

my hosts file is in this directory: "C:\Windows\System32\drivers\etc"

我的hosts文件位于以下目录中:“C:\ Windows \ System32 \ drivers \ etc”

yours will be something similar to that.

你的将是类似的东西。

Are you perhaps using NOD32 or any other antivirus that may cause problems?

您是否正在使用NOD32或任何其他可能导致问题的防病毒软件?

I encountered this issue today and just wanted to elaborate because my hosts file had "127.0.0.1 localhost" already defined.

我今天遇到了这个问题,只是想详细说明,因为我的hosts文件已经定义了“127.0.0.1 localhost”。

I was able to see the default IIS site by referencing localhost but when I tried debugging in my IDE it would always display "cannot display webpage" in IE and "Oops! Google Chrome cannot connect to localhost" in Chrome.

我通过引用localhost看到了默认的IIS站点,但是当我在IDE中尝试调试时,它总是会在IE中显示“无法显示网页”,并且Chrome中的“糟糕!谷歌浏览器无法连接到本地主机”。

I opened a command prompt and typed "netstat -a" and reviewed the results. I saw that my port used by my debugging web server was listed as "LISTENING" on the local address of [::1] only:

我打开一个命令提示符并输入“netstat -a”并查看结果。我看到我的调试Web服务器使用的端口仅在[:: 1]的本地地址上列为“LISTENING”:

TCP [::1]:64212 [ComputerName]:0 LISTENING

TCP [:: 1]:64212 [ComputerName]:0 LISTENING

What's unusual to me is that debugging worked for a period of time and then it seemed like all of a sudden it stopped. The first couple times it happened I re-installed Visual Web Developer Express 2010. This became rather annoying because it was a long process and the problem continued to resurface after what seemed to be an arbitrary period of time.

对我来说不同寻常的是,调试工作了一段时间,然后似乎突然停止了。它发生的前几次我重新安装了Visual Web Developer Express 2010.这变得相当烦人,因为这是一个漫长的过程,并且问题在看起来是一段任意的时间后继续重现。

This latest time I changed my hosts file to include "::1 localhost" (the opposite of this solution and numerous others I found online) and that has resolved my issues with my debugging environment.

这个最新的时间我改变了我的hosts文件,包括“:: 1 localhost”(这个解决方案和我在网上发现的其他许多其他对象),这解决了我的调试环境问题。

I'm grateful this resolved my issue but am still curious as to why and how my debugging environment seems to change. Additionally, I'm curious why there are multiple loopback addresses other than 127.0.0.1. Is "::1" an ip6 standard? If so, shouldn't localhost be routing to 127.0.0.1 and interpreted by the tcp/ip stack as the same as ::1?

我很感激这解决了我的问题,但我仍然很好奇我的调试环境为何以及如何改变。另外,我很好奇为什么除了127.0.0.1之外还有多个环回地址。 “:: 1”是ip6标准吗?如果是这样,localhost是否应该路由到127.0.0.1并由tcp / ip堆栈解释为与:: 1相同?

I had this problem with Visual Studio 2013. I have set the Firewall system manually. This means that, at the time of communication by programs Firewall notify me. Incorrectly linked to "devenv.exe" was blocked by the Firewall. Correct mode of communication "devenv.exe" will solve the problem. in your case cheeck Firewall options and filtered communications.

我在Visual Studio 2013中遇到了这个问题。我手动设置了防火墙系统。这意味着,在通过程序通信时防火墙通知我。防火墙阻止了与“devenv.exe”的错误链接。正确的通信模式“devenv.exe”将解决问题。在你的情况下cheeck防火墙选项和过滤通信。
