• Template:
  • Web API Server (3.00beta4).b4xtemplate *updated
• Depends on:
  • WebApiUtils.b4xlib (v3.01) *updated
  • MiniORMUtils.b4xlib (v1.14)
  • sqlite-jdbc-3.39.3.0.jar (or your preferred version)
  • mysql-connector-java-8.0.30.jar (or your preferred version)

Introduction of :
1. ElementMatch (Pattern As String) As Boolean
2. CropElements (FullElements() As String, StartingElementIndex As Int) As String() -> (WebApiUtils.b4xlib)

With these new methods, I am trying to simplify the way writing APIs which I think make more sense to newbie of this Web API framework.

Example:

Sub Handle (req As ServletRequest, resp As ServletResponse)
    Request = req
    Response = resp
    Method = Request.Method.ToUpperCase
    Dim FullElements() As String = WebApiUtils.GetUriElements(Request.RequestURI)
    Elements = WebApiUtils.CropElements(FullElements, 3) ' 3 For Api handler
    Select Method
        Case "GET"
            If ElementMatch("") Then ' /api/categories
                GetCategories
                Return
            End If
            If ElementMatch("id") Then ' /api/categories/1
                GetCategoryById(ElementId)
                Return
            End If
        Case "POST"
            If ElementMatch("") Then ' /api/categories
                PostCategory
                Return
            End If  
        Case Else
            Log("Unsupported method: " & Method)
            ReturnMethodNotAllow
            Return
    End Select
    ReturnBadRequest
End Sub

Note: If you want to show help during Production, make sure run project in Debug mode at least once to generate help.html in Objects folder. Delete the old help.html and regenerate again if you have made new changes to the APIs. It is not recommend to enable the help page and expose it to public without protecting it.

A request to export a report (product list by category id) as Excel and PDF, I have updated the project based on XLUtils.
Anyone who are interested to get the example code can donate $10 (or $11) to me.

  • Note that commented hashtags are still working in Debug mode and can be used to generate static help.html for production in old ways
• New commented hashtag (e.g ' #POST) *Note: all commented hashtags are case insensitive

  • Not necessary to start the Method name with a Verb e.g CreateNewCategory instead of PostCategory

• Template:
  • Web API Server (3.51).b4xtemplate
• Libraries:
  • WebApiUtils (3.05).b4xlib
  • MiniORMUtils (2.60).b4xlib

What's New:

• Updated template pointing to old libraries
• Reupload old libraries

I consider this template is quite stable and some developers may still want to use this version.
This version will let developers have this template in their collection without breaking the dependencies for Pakai v4 or v5.
