问题背景

VS2019开发.Net项目，在本地调试的时候，使用localhost可以正常访问接口，但通过127.0.0.1IP访问接口失败。提示 HTTP Error 400. The request hostname is invalid.

解决方案

修改applicationhost.config 配置文件

  1. 配置文件路径

配置文件路径一般在当前解决方案的根目录，有一个隐藏文件夹 .vs , 找到.vs下的项目名称xxx下的config文件夹，里面有一个 applicationhost.config 文件。完整路径为：.vs\xxx\config\applicationhost.config

  1. 打开配置文件

  1. 修改配置

打开配置文件 applicationhost.config，找到里面的 sites 节点，在对应的项目的 bindings 节点下增加 ip 相关的配置。增加以下配置信息

参考附录

1. .vs 文件夹

.vs目录是用来存储当前用户在解决方案中的工作配置，具体包括VS关闭前最后的窗口布局、最后打开的选项卡/操作记录/文件文档、某些自定义配置/开发环境、调试断点等这类设置信息和状态。这样每当用户关闭解决方案后再重新打开，就能继续之前的工作状态。

在VS2015之前的版本，这些信息都是散乱的保存在解决方案根目录下（最明显的参照物就是.suo文件），现在是将这些统一放在.vs这个隐藏文件夹里，如果没在Windows系统中开启查看隐藏的文件和文件夹，还是很容易无视的。

通常来说如果团队有使用源代码版本管理系统，这个文件夹都是要加入忽略规则的，毕竟没必要同步每个人的使用习惯和当前工作进度。而且.vs目录本身具有临时性，就算删除后也完全不影响解决方案的启动和运行，反正vs也会自动重新生成，只是之前的工作配置及记录没有了，也就是相当于第一次打开这个项目。

2. applicationhost.config 文件

  • 使用 IIS 7 及更高版本时，ApplicationHost.config是配置系统的根文件。 它包括所有站点、应用程序、虚拟目录和应用程序池的定义，以及 Web 服务器设置的全局默认值， (类似于machine.config，以及.NET Framework设置) 的根web.config。
  • IIS 设置的配置架构文件路径： C:\Windows\System32\inetsrv\config\schema
