Bonjour à tous,
Je copie ici un message posté sur d'autres forums. Merci d'excuser de ne pas avoir traduit.
------------------
In ASP.Net MVC Core 2, we are trying to call the Linkedin web API with OAuth authentication.
We are able to declare the OAuth authentication service and retrieve the access token the from Linkedin as shown in the code below.
Now we would like to request the API from a controller. To do that, we have to get the access token from the OAuth service we have declared with the AddOAuth method. How can we do that? No way to find an example anywhere.
Thanx for your help, we are really stuck.
services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie("linkedin_login", options =>
{
options.LoginPath = new PathString("/login"); // "/Account/LogIn";
options.LogoutPath = new PathString("/logout"); // "/Account/LogOff";
})
.AddOAuth("LinkedIn", options =>
{
options.SignInScheme = "linkedin_login";
options.ClientId = Configuration["linkedin:clientId"];
options.ClientSecret = Configuration["linkedin:clientSecret"];
options.CallbackPath = new PathString("/signin-linkedin");// "/signin-linkedin";
options.AuthorizationEndpoint = "https://www.linkedin.com/oauth/v2/authorization";
options.TokenEndpoint = "https://www.linkedin.com/oauth/v2/accessToken";
options.UserInformationEndpoint = "https://api.linkedin.com/v1/people/~:(id,first-name,last-name,formatted-name,email-address,picture-url,picture-urls,headline,public-profile-url,industry,three-current-positions,three-past-positions,positions::(original))";
//
// To save the tokens to the Authentication Properties we need to set this to true
// See code in OnTicketReceived event below to extract the tokens and save them as Claims
options.SaveTokens = true;//JCV News !!
options.Scope.Add("r_basicprofile");
options.Scope.Add("r_emailaddress");
options.Events = new OAuthEvents
{
OnCreatingTicket = async context =>
{
#region OnCreatingTicket
// Retrieve user info
var request = new HttpRequestMessage(HttpMethod.Get, context.Options.UserInformationEndpoint);
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", context.AccessToken);
request.Headers.Add("x-li-format", "json"); // Tell LinkedIn we want the result in JSON, otherwise it will return XML
//… blah blah blah…
Searching... wondering...
