IConfigurationRoot for AngularAppUrl and Custom Email Sender #4168

khai created 6 years ago

Hello,

I am trying to config two things which are relevant to IConfigurationRoot to get config inside AppSettings.json.

I want to inject IConfiguration to file AngularAppUrlService.cs. However, those fields are read-only therefore I cannot assign new value to it.
I implement new class for Email Sender Service and I put it outside ASPNETZero Sourcecode. However, I cannot inject IConfigurationRoot to my class. I got this error.

Please help me to archive this. Thank you

Hi @Khai,

Sorry for the delay, we have missed your question somehow.

You canfirst add setters for those fields in AppUrlServiceBase:

public abstract string EmailActivationRoute { get; set; }

Then you can change the fields in AngularAppUrlService like this:

public override string EmailActivationRoute { get; set; }

After all, you can set the fields. I suggest you to create an Init method for AppUrlServiceBase and do it in that method instead of it's constructor.

You need to define a module for your class library and depend on the module which contains IConfigurationRoot. Or instead of injecting IConfigurationRoot, you can simply use

IConfigurationRoot _appConfiguration = AppConfigurations.Get( typeof(NameOfYourModuleWhichContainsConfigFile).GetAssembly().GetDirectoryPathOrNull() );

For the first question, after I added setter to both of the override fields, I see that the instance of AppUrlService is NullAppUrlService and I cannot use it. Please help me to figure out that.

Hi @Khai,

So, your project builds but is this happening on runtime ? If so, can you share your AppUrlServiceBase, AngularAppUrlService, MvcAppUrlService and NullAppUrlService ?

Thanks.

Hello, these are my files.

1. AppUrlServiceBase

public abstract class AppUrlServiceBase : IAppUrlService, ITransientDependency
    {
        public abstract string EmailActivationRoute { get; set; }

        public abstract string PasswordResetRoute { get; set; }

        protected readonly IWebUrlService WebUrlService;
        protected readonly ITenantCache TenantCache;

        protected AppUrlServiceBase(IWebUrlService webUrlService, ITenantCache tenantCache, IConfigurationRoot appConfigurationRoot)
        {
            WebUrlService = webUrlService;
            TenantCache = tenantCache;
            this.Initialize(appConfigurationRoot);
        }

        private void Initialize(IConfigurationRoot appConfigurationRoot)
        {
            EmailActivationRoute = appConfigurationRoot["WebUIConfig:EmailActivationRoute"];
            PasswordResetRoute = appConfigurationRoot["WebUIConfig:PasswordResetRoute"];
        }

        public string CreateEmailActivationUrlFormat(int? tenantId)
        {
            return CreateEmailActivationUrlFormat(GetTenancyName(tenantId));
        }

        public string CreatePasswordResetUrlFormat(int? tenantId)
        {
            return CreatePasswordResetUrlFormat(GetTenancyName(tenantId));
        }

        public string CreateEmailActivationUrlFormat(string tenancyName)
        {
            var activationLink = WebUrlService.GetSiteRootAddress(tenancyName).EnsureEndsWith('/') + EmailActivationRoute + "?userId={userId}&confirmationCode={confirmationCode}";

            if (tenancyName != null)
            {
                activationLink = activationLink + "&tenantId={tenantId}";
            }

            return activationLink;
        }

        public string CreatePasswordResetUrlFormat(string tenancyName)
        {
            var resetLink = WebUrlService.GetSiteRootAddress(tenancyName).EnsureEndsWith('/') + PasswordResetRoute + "?userId={userId}&resetCode={resetCode}";

            if (tenancyName != null)
            {
                resetLink = resetLink + "&tenantId={tenantId}";
            }

            return resetLink;
        }


        private string GetTenancyName(int? tenantId)
        {
            return tenantId.HasValue ? TenantCache.Get(tenantId.Value).TenancyName : null;
        }
    }

2. AngularAppUrlService

public class AngularAppUrlService : AppUrlServiceBase
    {
        public override string EmailActivationRoute { get; set; }

        public override string PasswordResetRoute { get; set; }

        public AngularAppUrlService(
                IConfigurationRoot appConfigurationRoot,
                IWebUrlService webUrlService,
                ITenantCache tenantCache
            ) : base(
                webUrlService,
                tenantCache,
                appConfigurationRoot
            )
        {
            
        }
    }

3. MvcAppUrlService (I don't see this file)

4. NullAppUrlService

public class NullAppUrlService : IAppUrlService
    {
        public static IAppUrlService Instance { get; } = new NullAppUrlService();

        private NullAppUrlService()
        {
            
        }

        public string CreateEmailActivationUrlFormat(int? tenantId)
        {
            throw new NotImplementedException();
        }

        public string CreatePasswordResetUrlFormat(int? tenantId)
        {
            throw new NotImplementedException();
        }

        public string CreateEmailActivationUrlFormat(string tenancyName)
        {
            throw new NotImplementedException();
        }

        public string CreatePasswordResetUrlFormat(string tenancyName)
        {
            throw new NotImplementedException();
        }
    }

Hi,

Actually, I wanted you to add a public Initialize method like this:

public abstract class AppUrlServiceBase : IAppUrlService, ITransientDependency
{
    public abstract string EmailActivationRoute { get; set; }

    public abstract string PasswordResetRoute { get; set; }

    protected readonly IWebUrlService WebUrlService;
    protected readonly ITenantCache TenantCache;

    IConfigurationRoot _appConfigurationRoot;
    
    protected AppUrlServiceBase(IWebUrlService webUrlService, ITenantCache tenantCache, IConfigurationRoot appConfigurationRoot)
    {
        WebUrlService = webUrlService;
        TenantCache = tenantCache;
        _appConfigurationRoot = appConfigurationRoot;
    }

    public void Initialize()
    {
        EmailActivationRoute = _appConfigurationRoot["WebUIConfig:EmailActivationRoute"];
        PasswordResetRoute = _appConfigurationRoot["WebUIConfig:PasswordResetRoute"];
    }

    public string CreateEmailActivationUrlFormat(int? tenantId)
    {
        return CreateEmailActivationUrlFormat(GetTenancyName(tenantId));
    }

    public string CreatePasswordResetUrlFormat(int? tenantId)
    {
        return CreatePasswordResetUrlFormat(GetTenancyName(tenantId));
    }

    public string CreateEmailActivationUrlFormat(string tenancyName)
    {
        var activationLink = WebUrlService.GetSiteRootAddress(tenancyName).EnsureEndsWith('/') + EmailActivationRoute + "?userId={userId}&confirmationCode={confirmationCode}";

        if (tenancyName != null)
        {
            activationLink = activationLink + "&tenantId={tenantId}";
        }

        return activationLink;
    }

    public string CreatePasswordResetUrlFormat(string tenancyName)
    {
        var resetLink = WebUrlService.GetSiteRootAddress(tenancyName).EnsureEndsWith('/') + PasswordResetRoute + "?userId={userId}&resetCode={resetCode}";

        if (tenancyName != null)
        {
            resetLink = resetLink + "&tenantId={tenantId}";
        }

        return resetLink;
    }


    private string GetTenancyName(int? tenantId)
    {
        return tenantId.HasValue ? TenantCache.Get(tenantId.Value).TenancyName : null;
    }
}

Then, you can use it when you inject IAppUrlService (also add Initialize method to interface as well).

But, the thing I don't understand is, do you have a build error or runtime error ?

Hello, The error appears at runtime (it means I can compile it successfully). Is that a bug?

Hi @Khai,

I haven't tried this code in runtime but it is not designed to work this way initially. Can you share the runtime exception message ?
