获取steam游戏版本号，检查是否有更新

Question

我正在尝试创建一个 NPM 模块来从 appID 获取 Steam 游戏版本。

目前，我可以通过以下方式获取游戏信息 https://store.steampowered.com/api/appdetails?appids=730 （730是CSGO appID）

如何获取当前游戏版本？

这样我就可以检查是否有可用的更新。

Answer 1

您可以使用

steamdb.info

或steamcmd查询buildid。每当文件发生更改时，此值都会增加。

Answer 2

我发现SteamCMD是一个笨拙的破损工具。如果您只想在游戏服务器运行时快速检查更新。因此，如果您想停止服务器并更新检查结果，只需在代码中进行检查和决定。那么 SteamCMD 就不是你的朋友了。

所以我写了一个简短的 powershell 脚本来从 SteamCMD 中获取更多有用的信息。

param(
    [Parameter(Mandatory)][string]$SteamCMD,          # Path to SteamCMD.exe, path can have spaces. Example: -SteamCMD C:\SteamCMD\steamcmd.exe
    [Parameter(Mandatory)][string]$AppID,             # Steam AppID. Example for ARK Ascended server: -AppID 2430930
    [Parameter(Mandatory)][string]$branch,            # Branch you want to check for updates. Example: -branch public
    [Parameter(Mandatory)][string]$force_install_dir, # Path of local install you want to check for updates, path cannot have spaces (SteamCMD limitation)
                                                      # Example: -force_install_dir C:\SERVERS\ArkAscended\server\
    [ValidateSet("update_available","installed_version","latest_version","app_status_json","app_info_json")]
    [Parameter(Mandatory)][string]$output="update_available"
                                                      # What output do you want.
                                                      # -output update_available (will output single line with true or false)
                                                      # -output installed_version (will output a single line with a number)
                                                      # -output latest_version (will output a single line with a number)
                                                      # -output app_status_json (will output what SteamCMD should have output when they would have developed their tooling right)
                                                      # -output app_info_json (will output what SteamCMD should have output when they would have developed their tooling right)
