Share My Creation [Project Template] [Web] API Server 2

Version: 2.05
Description: Create Web API Server using B4X project template

Sample project: Support Ticketing System

Web API Server.png


If you don't want to connect to any SQL database, see MinimaList API Server
For older version, see Web API Server (v1.16)

Template:
  • Web API Server (2.05).b4xtemplate
Depends on:
GitHub:
Features:
  • ApiHandler and WebHandler are used for routing to Controller classes
  • HelpHandler (optional)
    • API documentation is generated automatically. You don't need external tools (e.g Postman or Swagger) for testing.
    • Access tokens can be embeded into request header in HelpHandler.
    • Controller classes are added to a list in Main module to show in the documentation.
  • Configuration
    • Web and API paths
    • Versioning
    • Simple JSON Response (Map or List)
    • Session
    • Cookies
    • Welcome message
  • Endpoint
    • Endpoint name is based on controller's name by default e.g ProductsController produces /web/api/v2/products
    • Endpoint name can be overridden by using #Name tag e.g /web/api/v2/product
    • Custom version name using #Version tag e.g v2, live, demo, dev, staging
    • Description in documentation is set using #Desc tag (in Web API v1, it was set by #Desc1, #Desc2 or Literals that was very confusing)
    • API endpoint can be hidden using #Hide tag
  • Clients
Code example:
B4X: 
Private Sub GetCategory (id As Long)
    ' #Version = v2
    ' #Desc = Read one Category by id
    ' #Elements = [":id"]

    DB.Table = "tbl_category"
    DB.Find(id)
    If DB.Found Then
        HRM.ResponseCode = 200
        HRM.ResponseObject = DB.First
    Else
        HRM.ResponseCode = 404
        HRM.ResponseError = "Category not found"
    End If
    DB.Close
    ReturnApiResponse
End Sub

  • (new) WebApiController (version 1.04)
  • (new) MiniORMUtils (version 1.01)
  • (update) HelpHandler - JavaScript files for search is no longer generated during compilation.

    Thanks to projects Ticketing Support System and Shao.
  • (update) Some JavaScript files have been renamed using period instead of dash.
  • (remove) Dependency to MinimaList (You need to add MinimaListUtils manually if you want to use it).
    Build configuration and conditional compilation codes are kept.

Process_Globals
Version 2.04: 
Public SimpleResponse           As Boolean
Public SimpleResponseFormat     As String
Public SimpleResponseDataKey    As String
Version 2.05: 
Public SimpleResponse           As SimpleResponse

ConfigureResponse sub
Version 2.04: 
SimpleResponse = True
SimpleResponseFormat = "Auto"    ' no conversion
Version 2.05: 
SimpleResponse.Enable = True
SimpleResponse.Format = "Auto"    ' no conversion

ShowPage sub in CategoryController
Version 2.04: 
    If Main.SimpleResponse Then
        If Main.SimpleResponseFormat = "Map" Then
            ' Script file is using dash
        Else
            ' Script file is using dash       
        End If
    Else
            ' Script file is using dash
    End If
Version 2.05: 
    If Main.SimpleResponse.Enable Then
        If Main.SimpleResponse.Format = "Map" Then
            ' Script file is now using period
        Else
            ' Script file is now using period
        End If
    Else
        ' Script file is now using period
    End If

JavaScript file name changed (one example)
Version 2.04:

Version 2.05:

Beta 2 is an old version.
Please download from the first post which is the stable version.

By the way, you should put all libraries into B4J Additional folder. MiniORMUtils can put inside B4X Additional folder.

In version 2.06, Main module is more compact.

Most of the code has moved to 2 new classes, ServerConfiguration and DatabaseConfiguration.
In most cases, you don't need to modify ServerConfiguration.
To create the database tables, edit CreateDatabase sub inside DatabaseConfiguration.

The code for Main is as follow:

Main: 
Sub Process_Globals
    Public Server                 As Server
    Public Config                 As Map
    Public Element                As Element
    Public Controllers            As List
    Public SimpleResponse         As SimpleResponse
    Public DBConnector            As DatabaseConnector
    Public PRINT_FULL_REQUEST_URL As Boolean
    Public SESSIONS_ENABLED       As Boolean
    Public COOKIES_ENABLED        As Boolean
    Public COOKIES_EXPIRATION     As Long
    Public Const VERSION          As String = "2.06"
    'Public Const PREFIX          As String = "WebAPI_v2_" ' use for cookies and sessions
End Sub

' <link>Open in browser|http://localhost:19800/web</link>
Sub AppStart (Args() As String)
    Server.Initialize("")
    Config.Initialize
    SimpleResponse.Initialize
   
    ' Read environment settings
    If Not(File.Exists(File.DirApp, "config.ini")) Then
        File.Copy(File.DirAssets, "config.example", File.DirApp, "config.ini")
    End If
    Config = WebApiUtils.ReadMapFile(File.DirApp, "config.ini")
    Config.Put("VERSION", VERSION)
    'Config.Put("PREFIX", PREFIX)
   
    Dim sv As ServerConfiguration
    sv.Initialize
    sv.EnableCORS = True
    sv.StaticFilesFolder = File.Combine(File.DirApp, "www")
    sv.Update
    sv.ShowWelcomeText
   
    Dim db As DatabaseConfiguration
    db.Initialize
    db.ConfigureDatabase
   
    Server.Start
   
    ' Show Controllers in Documentation
    Controllers.Initialize
    Controllers.Add("CategoriesController")
    Controllers.Add("ProductsController")
    Controllers.Add("FindController")
   
    PRINT_FULL_REQUEST_URL = True
    StartMessageLoop
End Sub
