我正在尝试使用OpenIdDict创建一个消耗.NET Core Web API的Angular2 SPA,其中包含凭据流.在为这个问题创建一个repro解决方案时,我还详细介绍了自述文件中的所有步骤,所以希望这篇文章对像我这样的新手有用.请在这些存储库中找到完整的repro解决方案：
>服务器端(.NET Core OpenIdDict),包含构建您自己的详细说明：https://github.com/Myrmex/repro-oidang
>客户端(Angular2)：https://github.com/Myrmex/repro-angoid
至于服务器端,我按照OpenIdDict提供的关于此流程的示例(https://github.com/openiddict/openiddict-samples/blob/master/samples/PasswordFlow).以下是Startup中最相关的位：
public void ConfigureServices(IServiceCollection services)
{
services.AddCors();
services.AddEntityFrameworksqlServer()
.AddDbContext<CatalogContext>(options =>
options.UsesqlServer(Configuration.GetConnectionString("Catalog")))
.AddDbContext<ApplicationDbContext>(options =>
options.UsesqlServer(Configuration.GetConnectionString("Catalog")));
services.AddIdentity<ApplicationUser,ApplicationRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
services.AddOpenIddict<ApplicationDbContext>()
.DisableHttpsRequirement()
.EnableTokenEndpoint("/connect/token")
.EnablelogoutEndpoint("/connect/logout")
.EnableUserinfoEndpoint("/connect/userinfo")
.AllowPasswordFlow()
.AllowRefreshTokenFlow()
.AddEphemeralSigningKey();
services.AddMvc()
.AddJsonOptions(options =>
{
options.SerializerSettings.ContractResolver =
new Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver();
});
// add my services
// ...
services.AddTransient<IDatabaseInitializer,DatabaseInitializer>();
services.AddSwaggerGen();
}
public void Configure(IApplicationBuilder app,IHostingEnvironment env,ILoggerFactory loggerFactory,IDatabaseInitializer databaseInitializer)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
loggerFactory.AddNLog();
app.UseDefaultFiles();
app.UseStaticFiles();
app.UseCors(builder =>
builder.WithOrigins("http://localhost:4200")
.AllowAnyHeader()
.AllowAnyMethod());
app.USEOAuthValidation();
app.USEOpenIddict();
app.UseMvc();
databaseInitializer.Seed().GetAwaiter().GetResult();
env.ConfigureNLog("nlog.config");
app.UseSwagger();
app.UseSwaggerUi();
}
如果我用Fiddler测试它,它工作正常：令牌请求获取令牌,然后我可以将它包含在Authorization标头中以访问任何受保护的API,它按预期返回JSON数据.
示例令牌请求：
POST http://localhost:51346/connect/token Content-Type: application/x-www-form-urlencoded grant_type=password&scope=offline_access profile email roles&resource=http://localhost:4200&username=...&password=...
样本资源请求：
GET http://localhost:51346/api/values Content-Type: application/json Authorization: Bearer ...received token here...
然而,在客户端,每当我尝试相同的请求时,我都会收到401错误;看着日志,似乎Angular2 Http服务根本没有发送所需的头,因为我收到错误身份验证被跳过,因为没有收到持有者令牌(请参阅下面的更多日志条目).
检索一些资源的服务是这样的：
import { Injectable } from '@angular/core';
import { Http,Response } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import { SettingsService } from './settings.service';
import { AuthenticationService } from './authentication.service';
export interface ICategory {
id: string;
name: string;
}
@Injectable()
export class CategoryService {
constructor(
private _http: Http,private _settings: SettingsService,private _authService: AuthenticationService) { }
public getCategories(): Observable<ICategory[]> {
let url = this._settings.apiBaseUrl + 'categories';
let options = {
headers: this._authService.createAuthHeaders({
'Content-Type': 'application/json'
})
};
return this._http.get(url,options).map((res: Response) => res.json())
.catch((error: any) => Observable.throw(error.json().error || 'server error'));
}
}
帮助程序createAuthHeaders只获取表示Header(https://angular.io/docs/ts/latest/api/http/index/Headers-class.html)条目的某些属性,检索存储的标记,将Authentication条目附加到标题,然后返回：
public createAuthHeaders(headers?: { [name: string]: any }): Headers {
let auth = new Headers();
if (headers) {
for (let key in headers) {
if (headers.hasOwnProperty(key)) {
auth.append(key,headers[key]);
}
}
}
let tokenResult = this._localStorage.retrieve(this._settings.tokenStorageKey,true);
if (tokenResult) {
auth.append('Authentication','Bearer ' + tokenResult.access_token);
}
return auth;
}
然而,当尝试将响应映射到JSON对象(JSON输入的意外结束)时,此请求获得401响应然后Angular抛出.
我必须补充说,一旦客户端获得令牌,它就会发出另一个请求,以检索用户信息,这样可以正常工作;这是它(获取用户信息后的代码)：
public login(name: string,password: string) {
let body = 'grant_type=password&scope=offline_access profile email roles' +
`&resource=${this._settings.appBaseUrl}&username=${name}&password=${password}`;
this._http.post(
this._settings.authBaseUrl + `token`,body,{
headers: new Headers({
'Content-Type': 'application/x-www-form-urlencoded'
})
}).map(res => res.json())
.subscribe(
(token: ITokenResult) => {
if (token.expires_in) {
token.expires_on = this.calculateExpirationDate(+token.expires_in);
}
this._localStorage.store(this._settings.tokenStorageKey,token,true);
// get user info
this._http.get(this._settings.authBaseUrl + 'userinfo',{
headers: new Headers({
'Content-Type': 'application/json','Authorization': 'Bearer ' + token.access_token
})
}).map(res => res.json())
.subscribe((info: IUserInfoResult) => {
let user: IUser = {
id: info.name,email: info.email,name: info.name,firstName: info.given_name,lastName: info.family_name,role: info.role,verified: info.email_verified
};
this._localStorage.store(this._settings.userStorageKey,user,true);
this.userChanged.emit(user);
},error => {
console.log(error);
});
},error => {
console.log(error);
});
}
但是,使用上述服务构建的任何其他请求都会失败.使用引用函数构建的标题有什么问题？
以下是服务器端的一些日志条目：

解决方法
您的不记名令牌使用不正确.
auth.append('Authentication','Bearer ' + tokenResult.access_token) // wrong
auth.append('Authorization','Bearer ' + tokenResult.access_token) // right
