Angular 401 error

When tokens expire we will generally get a 401 Unauthorized response back from the server. This gives us an. You have to define the handleError method. have a look at the example here. You need to append correct CORS headers to your error response as well as success. and was due to the server not sending the correct response ( even though the console log stated a 401 the Angular error had status 0).

    Angular error

    All works well, except the method handle401Error. It does not execute, unless I add subscribe in the interceptor. The accepted answer doesn' t work for later versions of angular. x ( and maybe even earlier) you need to write the interceptor differently: / / http interceptor to handle redirection to login on 401 response from API. The problem is when the server sends 401 error, the browser immediately stops with " Unauthorized" message, or with login pop- up window ( when authentication HTTP header is sent by the server), but Angular can' t capture with it' s interceptor. Your problem is missing or wrong content type header. For login not to send OPTIONS requests your content type should be one of the standard form types: application/ x- www- form- urlencoded or multipart/ form- data. My question is all the get request are working fine. But when i use post request I got Error 401 ( Unauthorized User).
