ReplyDeleteGood Morning Venkat. This is Vijay from Chicago and i'm big fan of your tutorials as they are awesome, excellent and mind blowing... in fact i requested you in the past whether you can take online session on MVC.
ReplyDeleteWell,i need some information or tutorial on how to consume WCF end points through Angular as well as how to solve CORS issue when we develop a project using VSCode.. if you would like i can text you my personal email address.
Thanks
Vijay
Hello Vijay,
DeleteI has the similar issue related with CORS (Error Message: Fail to load (API Uri) No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin http://localhost:4200' is therefore not allowed access) and below I have mentioned couple of possible solution.
It is not an Angular error. It afflicts all web apps equally, and all the possible fixes we’ll look at below are actually modifying the API header or server or the browser.
1st CORS header (requires server changes):
-----------------------------------------
CORS (Cross-Origin Resource Sharing) is a way for the server to say “I will accept your request, even though you came from a different origin.” This requires cooperation from the server – so if you can’t modify the server (e.g. if you’re using an external API), this approach won’t work.
Modify the server to add the header Access-Control-Allow-Origin: * to enable cross-origin requests from anywhere (or specify a domain instead of *). This should solve your problem.
OR Add the following HTTP Header in server at the response of the receiving end:
Access-Control-Allow-Headers: Content-Type
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Origin: *
2nd choice: Proxy Server:
-------------------------
If you can’t modify the server, you can run your own proxy. And this proxy can return the Access-Control-Allow-Origin header if it’s not at the Same Origin as your page.
Instead of sending API requests to some remote server, you’ll make requests to your proxy, which will forward them to the remote server.
The server you are making the request to have to implement CORS to grant JavaScript from your website access. Your JavaScript can't grant itself permission to access another website.
update name
DeleteRun Windows power shell in admin mode and type r and hit enter. And another one thing to tell in addition is if we are creating a api at the same time we should not have another visual studio window open. Close all the windows before creating our api project. Run visual studio in administrator mode. And follow the steps as I have mentioned. Thanks, happy coding .
