Introduction

The easiest way of starting a new project using ABP and module-zero is to create a template on templates page. Remember to check "Include module zero".

After creating and downloading your project,

• Open your solution on Visual Studio 2015+.
• Select the 'Web' project as startup project.
• Open Package Manager Console, select 'EntityFramework' project as Default project and run the EntityFramework's 'Update-Database' command. This will create the database. You can change connection string from web.config.
• Run the application. User name is 'admin' and password is '123qwe' as default.

In this template, multi-tenancy is enabled by default. You can disable it in Core project's module class if you don't need.

Social Logins

Startup template supports Facebook, Twitter and Google+ logins. In the web.config, you can see the following settings:

<add key="ExternalAuth.Facebook.IsEnabled" value="false" />
<add key="ExternalAuth.Facebook.AppId" value="" />
<add key="ExternalAuth.Facebook.AppSecret" value="" />

<add key="ExternalAuth.Twitter.IsEnabled" value="false" />
<add key="ExternalAuth.Twitter.ConsumerKey" value="" />
<add key="ExternalAuth.Twitter.ConsumerSecret" value="" />

<add key="ExternalAuth.Google.IsEnabled" value="false" />
<add key="ExternalAuth.Google.ClientId" value="" />
<add key="ExternalAuth.Google.ClientSecret" value="" />

Here, you can enable which you need. Surely, you must have application keys and passwords which you need to get from related social web site. You can find guides from web to learn how to obtain this keys. Once you enable a social login and enter true keys, you will see a button in the login page. You can implement other logins as similar.

Token Based Authentication

Startup template uses cookie based authentication for browsers. However, if you want to consume Web APIs or application services (those are exposed via dynamic web api) from a mobile application, you probably want a token based authentication mechanism. Startup template includes bearer token authentication infrastructure. AccountController in .WebApi project contains Authenticate action to get the token. Then we can use the token for next requests.

Here, Postman (chrome extension) will be used to demonstrate requests and responses.

Authentication

Just send a POST request to http://localhost:6334/api/Account/Authenticate with Context-Type="application/json" header as shown below:

We sent a JSON request body includes userNameOrEmailAddress and password. Also, tenancyName should be sent for tenant users. As seen above, result property of returning JSON contains the token. We can save it and use for next requests.

Use API

After authenticate and get the token, we can use it to call any authorized action. All application services are available to be used remotely. For example, we can use the Tenant service to get a list of tenants:

Just made a POST request to http://localhost:6334/api/services/app/tenant/GetTenants with Content-Type="application/json" and Authorization="Bearer your- auth-token ". Request body was just empty {}. Surely, request and response body will be different for different APIs.

Almost all operations available on UI are also available as Web API (since UI uses the same Web API) and can be consumed easily.

Migrator Console Application

Startup template includes a tool, Migrator.exe, to easily migrate your databases. You can run this application to create/migrate host and tenant databases.

This application gets host connection string from it's own .config file. It will be same in the web.config at the beggining. Be sure that the connection string in config file is the database you want. After getting host connection sring, it first creates the host database or apply migrations if it does already exists. Then it gets connection strings of tenant databases and runs migrations for those databases. It skips a tenant if it has not a dedicated database or it's database is already migrated for another tenant (for shared databases between multiple tenants).

You can use this tool on development or on product environment to migrate databases on deployment, instead of EntityFramework's own Migrate.exe (which requires some configuration and can work for single database in one run).

Unit Testing

Startup template includes test infrastructure setup and a few tests under the .Test project. You can check them and write similar tests easily. Actually, they are integration tests rather than unit tests since they tests your code with all ASP.NET Boilerplate infrastructure (including validation, authorization, unit of work...).
