问题

I have a function that allows the end user to execute a Workflow (containing many APIs) or schedule it to run as a background job.

Example: User1 creates Workflow1, which contains 3 APIs (Api1, Api2, Api3), and configures it to run at 9AM every day.

I use HttpClient to call each API like this:

var client = new HttpClient { BaseAddress = new Uri("http://localhost/") };
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = client.PostAsJsonAsync("/api/services/myApp/workflow/Api1?input=something", "").Result;

How do I add the credentials of User1 to the request while the user is not logged in to the application (because it will run automatically as a scheduled job)?

Update 1

I decided to use reflection to call an API by string name.

In the case of executing an API directly, how do I run it under a specific permission?

Update 2

I have put my code inside a using block, but all APIs were fired successfully:

using (_session.Use(1, 3)) // 3 is the Id of User1, who has no permissions
{
    // Execute operator
    switch (input.Operator.Type)
    {
        case "api":
            executeApiResult = await ExecuteApi(input);
            break;
        case "procedure":
            executeApiResult = await ExecuteProcedure(input);
            break;
        default:
            return new ExecuteOperatorOutput
            {
                Result = new ExecuteOperatorResult { Status = false, Message = $"Wrong operator type: {input.Operator.Type}" },
                WorkflowStatus = false
            };
    }
}

You can override current session values and call your method inside the using block.

Declare your API methods as public virtual as there are some restrictions for AbpAuthorize.

You have two options.

1- You can make those Application Services anonymously accessible. And if you want it to be secure, send an encrypted security token.

2- You didn't mention if your project is MVC or Angular. I assume you have Angular version. You need a bearer token to make authenticated requests. First you have to authenticate user and get a token. Then add this bearer token to every request.

You have to research for using bearer tokens in asp.net core...
