DESIGN

SETUP SERVICE

1. Create a ASP.NET Core MVC project

2. Install Scheduler.NET package from NUGET

3. AddSchedulerNet after AddMvc

   services.AddMvc().AddSchedulerNet(Configuration).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

4. Add UseSchedulerNet in Configure method

   app.UseSchedulerNet();

5. Update config file:

    	"SchedulerNet": {
    		"Hangfire": {
    			"StorageType": "SqlServer",
    			"ConnectionString": "Server=.\\SQLEXPRESS;Database=Scheduler.NET;Trusted_Connection=True;MultipleActiveResultSets=true;"
    		},
    		"StorageType": "SqlServer",
    		"ConnectionString": "Server=.\\SQLEXPRESS;Database=Scheduler.NET;Trusted_Connection=True;MultipleActiveResultSets=true;",
    		"UseToken": false,
    		"Tokens": [ "a1", "a2" ],
    		"TokenHeader": "SchedulerNET",
    		"IgnoreCrons": [ "* * * * *" ],
    		"Cache": {
    			"Type": "memory"
    			}
    		}
   

6. Create database: Scheduler.NET in MSSQL

7. Run the web application from port 5000

SETUP CLIENT

1. Create a dotnet core Console project

2. Install Scheduler.NET.Client package from NUGET

3. Add a test processor class ConsoleJobProcessor and update main method

    public class ConsoleJobProcessor : SimpleJobProcessor
    {
    	public override bool Process(JobContext context)
    	{
    		Console.WriteLine(JsonConvert.SerializeObject(context));
    		return true;
    	}
    }
   
    static void Main(string[] args)
    {
    	SchedulerNetHelper api = new SchedulerNetHelper("http://localhost:5000");
    	api.CreateJob(new Job { Name = typeof(ConsoleJobProcessor).FullName, Cron = "*/1 * * * *", Group = "Test", Content = "aaa" });
    	SchedulerNetClient client = new SchedulerNetClient("Test", "http://localhost:5000");
    	client.Init();
    	Console.Read();
    }
   

4. Run the console project

CallbackJob

1. Create a callbackjob:

    	SchedulerNetHelper api = new SchedulerNetHelper("http://localhost:5000");
    	api.CreateCallbackJob(new CallbackJob { Name = "job1", Content = "{}", Cron = "*/1 * * * *", Group = "group1", Method = HttpMethod.Get, Url = "http://www.baidu.com" });
   

2. Then the scheduler.net will request http://www.baidu.com every 1 minutes.
