CodeBeam.GoogleApis.Blazor

An open-source utility package for GoogleApis in Blazor.

Always aim for the easiest to use.

This repo is still in earlier stage of development, but all completed parts already tested with real world applications.

Documentation

Please look at API.

Usage

Preliminary: Set your google account and your project credentials

Set your google client. This process has no special thing with this library. Read the details.
Add the credential into appsettings.json file like the below example. (Not obligatory, but ClientId, ClientSecret and RedirectUrl is required for some features to use this library simpler.)

{
"GoogleClient": {
"client_id": "[CLIENT_ID]",
"project_id": "",
"auth_uri": "",
"token_uri": "",
"auth_provider_x509_cert_url": "",
"client_secret": "[CLIENT_SECRET]",
"redirect_url": "[REDIRECT_URL]"
}
}

Step 1: Inject Services

Add Services into program.cs

builder.Services.AddCodeBeamGoogleApiServices();

For blazor component files

@inject AuthServiceAuthService@inject CalendarServiceCalendarService

OR - For cs files

[Inject]AuthService AuthService {get;set;}[Inject] CalendarService CalendarService {get;set;}

Step 2: Implement whatever you want

privatevoidCreateCalendar(){GoogleCalendarListModelgoogleCalendarListModel=new(){Summary="Test Calendar",Description="Created By CodeBeam",TimeZone="Europe/Istanbul",};CalendarService.AddCalendar(googleCalendarListModel);}

Step 3: null. That's all.

Examples

How To Use Auth Service To Get Permission From a Google Account

Step 1. Request Authorization Code

privateasyncTaskRequestCode(){List<Scope>scopes=new();scopes.Add(Scope.OAuth2Email);//Not required, but useful for get user email in future.scopes.Add(Scope.Calendar);awaitAuthService.RequestAuthorizationCode(AuthService.GetClientId(),scopes,NavigationManager.BaseUri+"v1/browser-callback");//"v1/browser-callback" is your page that method returns and opens the page as a new tab}

Step 2. Get Access Token With Obtained Authorization Code in Step 1

These codes should be in the callback page.
Blazor Component

@page "/v1/browser-callback"

Code

[Parameter][SupplyParameterFromQuery]publicstringCode{get;set;}string _accessToken = "";protectedoverrideasyncTaskOnAfterRenderAsync(boolfirstRender){if(firstRender){varrequest=AuthService.AuthorizeCredential(Code,AuthService.GetCliendId(),AuthService.GetClientSecret(),NavigationManager.BaseUri+"v1/browser-callback");// This method is built in this package. You also can write your own method to process request result._accessToken=AuthService.GetValueFromCredential(request,CredentialValueType.AccessToken);}}

Step 3. You can store this access token (can also obtain refresh token etc. with same way) in your database or make a cookie. You can use this token to call calendar, drive etc. features.

How To Create a Calendar Event

Make an instance of GoogleCalendarEventModel and add it. Notice that for datetimes like event start and end, need to use GetProperDateTimeFormat method.

[Inject]CalendarServiceCalendarService{get;set;}
private void AddEvent(){GoogleCalendarEventModelgoogleCalendarEvent=new(){Summary="Test Event",Description="Some Description",Start=newStart{dateTime=CalendarService.GetProperDateTimeFormat(DateTime.Now)},End=newEnd{dateTime=CalendarService.GetProperDateTimeFormat(DateTime.Now)},};// If you don't know the id of calendar which will the event be added, use FindCalendarId method. In this case, the event added the calendar which has "Test Calendar" title.stringresult=CalendarService.AddEvent(googleCalendarEvent,CalendarService.FindCalendarId(CalendarValueType.Summary,"Test Calendar"));}

How To Get and Process Lists (Like Calendar and Event)

When you call the api to return a list of items (like calendars or events) it returns a root class. These classes can be find in the library. You can use the "items" property to reach list of items.

The Models

• GoogleCalendarListRoot -> The root calendar model which is a proper for GetCalendars() method result
• GoogleCalendarListModel -> The calendar model. GoogleCalendarListRoot.items has a List<GoogleCalendarListModel>
• GoogleCalendarEventRoot -> The root event model which is a proper for GetEvents() method result
• GoogleCalendarEventModel -> The event model. GoogleCalendarEventRoot.items has a List<GoogleCalendarEventModel>

Usage

GoogleCalendarListRootcalendars=CalendarService.GetCalendars();// calendars.items has the list of calendars.
