| | | 2 | | .SYNOPSIS |
| | | 3 | | Creates a grouped route context (prefix + shared options) for nested Add-KrMapRoute calls. |
| | | 4 | | .DESCRIPTION |
| | | 5 | | While the ScriptBlock runs, all Add-KrMapRoute calls inherit: |
| | | 6 | | - Prefix (prepended to -Path) |
| | | 7 | | - AuthorizationSchema / AuthorizationPolicy |
| | | 8 | | - ExtraImports / ExtraRefs |
| | | 9 | | - Arguments (merged; child overrides keys) |
| | | 10 | | Supports nesting; inner groups inherit and can override unless -NoInherit is used. |
| | | 11 | | .PARAMETER Server |
| | | 12 | | The Kestrun server instance to which the route will be added. |
| | | 13 | | If not specified, the function will attempt to resolve the current server context. |
| | | 14 | | .PARAMETER Options |
| | | 15 | | The options to apply to all routes in the group. |
| | | 16 | | .PARAMETER Prefix |
| | | 17 | | The path prefix for the group (e.g. '/todoitems'). |
| | | 18 | | .PARAMETER AuthorizationSchema |
| | | 19 | | Authorization schemes required by all routes in the group. |
| | | 20 | | .PARAMETER AuthorizationPolicy |
| | | 21 | | Authorization policies required by all routes in the group. |
| | | 22 | | .PARAMETER ExtraImports |
| | | 23 | | Extra namespaces added to all routes in the group. |
| | | 24 | | .PARAMETER ExtraRefs |
| | | 25 | | Extra assemblies referenced by all routes in the group. |
| | | 26 | | .PARAMETER Arguments |
| | | 27 | | Extra arguments injected into all routes in the group. |
| | | 28 | | .PARAMETER ScriptBlock |
| | | 29 | | ScriptBlock within which you call Add-KrMapRoute for relative paths. |
| | | 30 | | .PARAMETER FileName |
| | | 31 | | Path to a script file containing the scriptblock to execute. |
| | | 32 | | .PARAMETER NoInherit |
| | | 33 | | If set, do not inherit options from the parent group; only apply the current parameters. |
| | | 34 | | .PARAMETER PassThru |
| | | 35 | | If specified, the function will return the created route object. |
| | | 36 | | .EXAMPLE |
| | | 37 | | Add-KrRouteGroup -Prefix '/todoitems' -AuthorizationPolicy 'RequireUser' -ScriptBlock { |
| | | 38 | | Add-KrMapRoute -Verbs Get -Path '/' -ScriptBlock { 'all todos' } |
| | | 39 | | Add-KrMapRoute -Verbs Get -Path '/{id}' -ScriptBlock { "todo $($Context.Request.RouteValues['id'])" } |
| | | 40 | | Add-KrMapRoute -Verbs Post -Path '/' -ScriptBlock { write-KrResponse -InputObject 'create' } |
| | | 41 | | } |
| | | 42 | | Adds a new route group to the specified Kestrun server with the given prefix and options. |
| | | 43 | | .EXAMPLE |
| | | 44 | | Add-KrRouteGroup -Prefix '/todoitems' -FileName 'C:\Scripts\TodoItems.ps1' |
| | | 45 | | Add the new route group defined in the specified file. |
| | | 46 | | .NOTES |
| | | 47 | | This function is part of the Kestrun PowerShell module and is used to manage routes |
