我在Ionic应用程序中存储了凭证令牌,要执行注销操作,我需要删除其中存储的令牌。这是我的LoginService:
// imports skipped;
export class LoginService implements CanActivate {
private authToken: string;
private httpService: string;
constructor(
private handler: HttpBackend,
private router: Router,
private storage: Storage
) {
this.httpService = new HttpClient(handler);
}
private generateToken(login: string, password: string) {
return btoa(`${login}:${password}`);
}
authenticate(login: string, password: string, webserviceURL: string) {
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
Authorization: `Basic ${this.generateToken(login, password)}`
})
};
return this.httpClient.get(`http://${webserviceURL}/api/version/`, httpOptions);
}
async saveToken(login: string, password: string) {
this.authToken = this.generateToken(login, password);
return await this.storage.set('AUTH_TOKEN', this.authToken);
}
async getToken() {
return await this.storage.get('AUTH_TOKEN');
}
async clearData() {
this.authToken = null;
return await this.storage.remove('AUTH_TOKEN');
}
canActivate() {
if (this.authToken) {
return true;
}
this.router.navigateByUrl('login');
}
}
并且在对该服务的测试中,我得到了以下内容:
const expectedToken = btoa('testLogin:testPassword');
service.saveToken('testLogin', 'testPassword').then(() => {
service.getToken().then(savedToken => {
expect(savedToken).toEqual(expectedToken);
});
});
service.clearData().then(() => {
service.getToken().then(savedToken => {
expect(savedToken).toBe(null);
});
});
因此,无论何时我运行测试,最后一个测试用例都会失败,因为出于某种原因令牌不会从存储中删除。这是测试输出:Error: Expected 'dGVzdExvZ2luOnRlc3RQYXNzd29yZA==' to be null
。如何正确从存储中删除价值?
第二次尝试...如果您的代码在一种方法中运行,那么它必须全部嵌套,否则它将只在另一个方法中运行?
const expectedToken = btoa('testLogin:testPassword');
service.saveToken('testLogin', 'testPassword').then(() => {
service.getToken().then(savedToken => {
expect(savedToken).toEqual(expectedToken);
service.clearData().then(() => {
service.getToken().then(savedToken => {
expect(savedToken).toBe(null);
});
});
});
});
