CORS error when consuming ASP.NET Core 1.1 Web API from IONIC (Angular) app -


i have created asp.net core 1.1 web api consumed angular2 (ionic) app. @ beginning of project, getting cors errors, which, after modifications web api, able resolve. morning updated our live web api changes made on past week , reason or other, getting cors error again (when angular app consumes live web api - works fine connect web api running on localhost pc on lan). error is:

xmlhttprequest cannot load http://inspections.propworx.co.za/api/inspections. response preflight request doesn't pass access control check: no 'access-control-allow-origin' header present on requested resource. origin 'http://192.168.1.100:8100' therefore not allowed access.

i have following in web api startup.cs:

public void configureservices(iservicecollection services) {     services.addcors(options =>     {         options.addpolicy("sitecorspolicy",         builder => builder.allowanyorigin()         .allowanymethod()         .allowanyheader()         .allowcredentials());     });     ... }

and this:

public void configure(iapplicationbuilder app, ihostingenvironment env, iloggerfactory loggerfactory) {     app.usecors("sitecorspolicy");     ... }

in both cases, before services.addmvc() , app.usemvc respectively. still doesn't work. have tried adding 

services.configure<mvcoptions>(options => {     options.filters.add(new corsauthorizationfilterfactory("sitecorspolicy")); });

in configureservices, after services.addcors, no avail. have tried adding:

[enablecors("sitecorspolicy")]

to top of controllers, didn't help.

this working, , don't know couldve done it's not working :/ ideas anyone? thanks...

there problem there no web.config file... asp.net core doesnt seem generate 1 web api's, needed cors...

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
