Identity Server 4 CORS not configured












0















I have put my IS4 on a server and lets call it http://test.myis4.com. Now I am trying to login with an angular application against it, however I keep getting blocked by CORS. The angular client is being served with an MVC Core application and it runs on http://localhost:5002 port. I have tried to do this from my localhost by running it on that port.



On the IS4 server I have tried adding on the client the following:



new Client {
// code is omitted
AllowedCorsOrigins = new List<string>() { "http://localhost:5002" }
}


With the above I still get the CORS error, then I have tried adding it to the services direclty:



var cors = new DefaultCorsPolicyService(null)
{
AllowedOrigins = { "http://localhost:5002" }
};
services.AddSingleton<ICorsPolicyService>(cors);
services.AddIdentityServer()
//rest omitted


The above still gave me the same CORS error, my last attempt was to add it through application builder as such:



app.UseCors(builder => builder.WithOrigins("http://localhost:5002").AllowAnyHeader());
app.UseIdentityServer();
//rest omitted


With this last attempt it still did not work. I'm not quire sure what I'm doing wrong at this point. Any suggestions?

          On the second code block, that you've shown - you need to first AddIdentityServer() and then add the Cors Policy service and you can also do it straight after adding Identity server to the services. Something like:



          services.AddIdentityServer(options =>
          {
          // .. if you need something in general (can go without the options)
          })
          .AddCorsPolicyService<YOUR_IMPLEMENTATION_OF_ICorsPolicyService>()
          // rest omitted


          This is because the AddIdentitiyServer() overwrites the adding of the CORS service - Code.
