私は角を使用します。角度によってコールJwtController方法について：あなたは（その方法は、すべてのユーザーがアクセス可能でなければならないので、ないあなたのJwtController上）認証されたユーザーのみがアクセスできるようにしたいコントローラクラス（またはメソッド）で
login(userName: string, password: string)
{
return this.getLoginEndpoint(userName, password)
.map((response: Response) => this.processLoginResponse(response));
}
getLoginEndpoint(userName: string, password: string): Observable<Response>
{
// Body
// JwtRequest is a model class that I use to send info to the controller
let jwt = new JwtRequest();
jwt.GrantType = "password";
jwt.UserName = userName;
jwt.Password = password;
jwt.ClientId = "my_Issuer";
// Post requiest (I use getAuthHeader that attach to the header the
// authentication token, but it can also be omitted because it is ignored
// by the JwtController
return this.http.post(this.loginUrl, JSON.stringify(jwt),
this.getAuthHeader(true))
}
protected getAuthHeader(includeJsonContentType?: boolean): RequestOptions
{
// Hera I use this.authService.accessToken that is a my service where
// I have store the token received from the server
let headers = new Headers({
'Authorization': 'Bearer ' + this.authService.accessToken });
if (includeJsonContentType)
headers.append("Content-Type", "application/json");
headers.append("Accept", `application/vnd.iman.v01+json,
application/json, text/plain, */*`);
headers.append("App-Version", "01");
return new RequestOptions({ headers: headers });
}
private processLoginResponse(response: Response)
{
// process the response..
}
あなたが設定することができます：
[Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]
角度からの認証を必要とするコントローラメソッドを呼び出すには、getAuthHeader（）メソッドでヘッダーにトークンを添付する必要があります。
この投稿がお役に立てれば幸いです。
これはずっと良いです、ありがとう。 –
