[PowerShell] Using PowerShell commands to replace ping, telnet, curl in Windows
Situation
When creating a clean Windows VM or App Service in Azure cloud, it is often necessary to check the network status or if other service ports are open. Previously, I would use ping, telnet or curl to read the HTML content of other websites. However, they are not installed by default and I would have to install them myself. Then I realized that PowerShell is a tool that is always installed by default. So I found the corresponding commands that can be used, which quickly solved the network connectivity issue for me recently.
