javascript - 本地主机无法连接到 IIS 中的 ASP 文件

问题描述

[编辑：找到解决方案。我只是没有设置或尝试正确访问本地主机，这意味着文件没有被加载。一旦我尝试通过 localhost 而不是绝对路径访问文件，我发现它们有效。我会留下这个问题，以防它在未来对某人有所帮助。]

我正在尝试在 9 月份开始上课之前完成一个网络表格练习。目标很简单：制作一个接受一些用户输入的 HTML 文件，并将其发送到本地托管的 ASP 文件（不是 ASP.NET），以确认数据已实际发送。不需要解析数据，只需识别它是使用 GET 或 POST 成功发送的。

我已经制作了 HTML 文件，并且作为练习的一部分提供了 ASP 文件。我已经彻底检查了它们，并且元素正在正确发送数据，但 ASP 文件似乎没有正确接收它。

我已完成以下步骤，在运行 Windows 10 的笔记本电脑上使用 IIS 配置 ASP 文件：

但是，当我尝试使用 localhost/fileName.asp 作为 URL 浏览网站时，它无法正确加载。相反，我收到错误“localhost 拒绝连接”。当我尝试使用 IIS 管理器界面中的“浏览”按钮浏览该站点时，我收到错误消息“找不到本地主机应用程序”。

奇怪的是，当我在浏览器中打开 HTML 页面并单击提交按钮时，它会将我重定向到 .ASP 页面，但不会执行其中的任何内容。它只显示文件的文本内容。

作为参考，我在下面提供了我的 HTML 页面和 ASP 页面的代码。我已经从 HTML 页面中删除了输入元素，因为它们与我的问题无关。

HTML：

解决方案

根据您的描述，我认为这个问题与您的经典 aspo 代码无关。

我建议您可以尝试运行以下命令来检查 iplisten。

运行以下 cmd 命令：

netsh http show iplisten

如果您收到上述命令的输出不是 0.0.0.0，您可以尝试运行以下命令以删除其他 iplisten

netsh http delete iplisten ipaddress=aa.bb.cc.dd (where aa.bb.cc.dd is the IP address that we have to remmove)

netsh http add iplisten ipaddress=0.0.0.0

iisreset

如果这个解决方案不能解决你的问题，我建议你可以参考下面的文章来干净重装 IIS。
