我正在尝试在我的 ionic(4) cordova 应用程序中使用 Keycloak-js（来自 4.4.0.Final）库。 我已遵循示例和文档中的说明。 我已经安装了
cordova-plugin-browsertabcordova-plugin-deeplinkscordova-plugin-inappbrowser<preference name="AndroidLaunchMode" value="singleTask" />config.xml<widget id="org.phidatalab.radar_armt"....>
<plugin name="cordova-plugin-browsertab" spec="0.2.0" />

<universal-links>
<host name="keycloak-cordova-example.exampledomain.net" scheme="https">
<path event="keycloak" url="/login" />
</host>
</universal-links>
</widget>
我的服务使用
Keycloak-jsstatic init(): Promise<any> {
// Create a new Keycloak Client Instance
let keycloakAuth: any = new Keycloak({
url: 'https://exampledomain.net/auth/',
realm: 'mighealth',
clientId: 'armt',
});
return new Promise((resolve, reject) => {
keycloakAuth.init({
onLoad: 'login-required',
adapter: 'cordova-native',
responseMode: 'query',
redirectUri: 'android-app://org.phidatalab.radar_armt/https/keycloak-cordova-example.github.io/login'
}).success(() => {
console.log("Success")
resolve();
}).error((err) => {
reject(err);
});
});
}
我可以成功构建并运行

如果我尝试在浏览器上运行它，我会得到
"universalLink is undefined"我真的很需要一些帮助才能使其正常工作。我缺少什么？非常感谢任何形式的帮助。 或者是否有解决方法/示例让 keycloak 为离子（公共）客户端工作？
我在这里发布我的解决方案，因为我浪费了很多时间来获取适合我的环境的可用插件。
keycloak-js我的解决方案是使用
InAppBrowsercordovakeycloak-jsauthorization_codekeycloak-jskeycloak-js就是这里。 步骤1：安装
[cordova-inapp-browser][1]Step2：示例
keycloak-auth.service.tscordovaimport 'rxjs/add/operator/toPromise'
import {HttpClient, HttpHeaders, HttpParams} from '@angular/common/http'
import {Injectable} from '@angular/core'
import {JwtHelperService} from '@auth0/angular-jwt'
import {StorageService} from '../../../core/services/storage.service'
import {StorageKeys} from '../../../shared/enums/storage'
import {InAppBrowser, InAppBrowserOptions} from '@ionic-native/in-app-browser';
const uuidv4 = require('uuid/v4');
@Injectable()
export class AuthService {
URI_base: 'https://my-server-location/auth';
keycloakConfig: any;
constructor(
public http: HttpClient,
public storage: StorageService,
private jwtHelper: JwtHelperService,
private inAppBrowser: InAppBrowser,
) {
this.keycloakConfig = {
authServerUrl: 'https://my-server-location/auth/', //keycloak-url
realm: 'myrealmmName', //realm-id
clientId: 'clientId', // client-id
redirectUri: 'http://my-demo-app/callback/', //callback-url registered for client.
// This can be anything, but should be a valid URL
};
}
public keycloakLogin(login: boolean): Promise<any> {
return new Promise((resolve, reject) => {
const url = this.createLoginUrl(this.keycloakConfig, login);
const options: InAppBrowserOptions = {
zoom: 'no',
location: 'no',
clearsessioncache: 'yes',
clearcache: 'yes'
}
const browser = this.inAppBrowser.create(url, '_blank', options);
const listener = browser.on('loadstart').subscribe((event: any) => {
const callback = encodeURI(event.url);
//Check the redirect uri
if (callback.indexOf(this.keycloakConfig.redirectUri) > -1) {
listener.unsubscribe();
browser.close();
const code = this.parseUrlParamsToObject(event.url);
this.getAccessToken(this.keycloakConfig, code).then(
() => {
const token = this.storage.get(StorageKeys.OAUTH_TOKENS);
resolve(token);
},
() => reject("Count not login in to keycloak")
);
}
});
});
}
parseUrlParamsToObject(url: any) {
const hashes = url.slice(url.indexOf('?') + 1).split('&');
return hashes.reduce((params, hash) => {
const [key, val] = hash.split('=');
return Object.assign(params, {[key]: decodeURIComponent(val)})
}, {});
}
createLoginUrl(keycloakConfig: any, isLogin: boolean) {
const state = uuidv4();
const nonce = uuidv4();
const responseMode = 'query';
const responseType = 'code';
const scope = 'openid';
return this.getUrlForAction(keycloakConfig, isLogin) +
'?client_id=' + encodeURIComponent(keycloakConfig.clientId) +
'&state=' + encodeURIComponent(state) +
'&redirect_uri=' + encodeURIComponent(keycloakConfig.redirectUri) +
'&response_mode=' + encodeURIComponent(responseMode) +
'&response_type=' + encodeURIComponent(responseType) +
'&scope=' + encodeURIComponent(scope) +
'&nonce=' + encodeURIComponent(nonce);
}
getUrlForAction(keycloakConfig: any, isLogin: boolean) {
return isLogin ? this.getRealmUrl(keycloakConfig) + '/protocol/openid-connect/auth'
: this.getRealmUrl(keycloakConfig) + '/protocol/openid-connect/registrations';
}
loadUserInfo() {
return this.storage.get(StorageKeys.OAUTH_TOKENS).then( tokens => {
const url = this.getRealmUrl(this.keycloakConfig) + '/protocol/openid-connect/userinfo';
const headers = this.getAccessHeaders(tokens.access_token, 'application/json');
return this.http.get(url, {headers: headers}).toPromise();
})
}
getAccessToken(kc: any, authorizationResponse: any) {
const URI = this.getTokenUrl();
const body = this.getAccessTokenParams(authorizationResponse.code, kc.clientId, kc.redirectUri);
const headers = this.getTokenRequestHeaders();
return this.createPostRequest(URI, body, {
header: headers,
}).then((newTokens: any) => {
newTokens.iat = (new Date().getTime() / 1000) - 10; // reduce 10 sec to for delay
this.storage.set(StorageKeys.OAUTH_TOKENS, newTokens);
});
}
refresh() {
return this.storage.get(StorageKeys.OAUTH_TOKENS)
.then(tokens => {
const decoded = this.jwtHelper.decodeToken(tokens.access_token)
if (decoded.iat + tokens.expires_in < (new Date().getTime() /1000)) {
const URI = this.getTokenUrl();
const headers = this.getTokenRequestHeaders();
const body = this.getRefreshParams(tokens.refresh_token, this.keycloakConfig.clientId);
return this.createPostRequest(URI, body, {
headers: headers
})
} else {
return tokens
}
})
.then(newTokens => {
newTokens.iat = (new Date().getTime() / 1000) - 10;
return this.storage.set(StorageKeys.OAUTH_TOKENS, newTokens)
})
.catch((reason) => console.log(reason))
}
createPostRequest(uri, body, headers) {
return this.http.post(uri, body, headers).toPromise()
}
getAccessHeaders(accessToken, contentType) {
return new HttpHeaders()
.set('Authorization', 'Bearer ' + accessToken)
.set('Content-Type', contentType);
}
getRefreshParams(refreshToken, clientId) {
return new HttpParams()
.set('grant_type', 'refresh_token')
.set('refresh_token', refreshToken)
.set('client_id', encodeURIComponent(clientId))
}
getAccessTokenParams(code , clientId, redirectUrl) {
return new HttpParams()
.set('grant_type', 'authorization_code')
.set('code', code)
.set('client_id', encodeURIComponent(clientId))
.set('redirect_uri', redirectUrl);
}
getTokenUrl() {
return this.getRealmUrl(this.keycloakConfig) + '/protocol/openid-connect/token';
}
getTokenRequestHeaders() {
const headers = new HttpHeaders()
.set('Content-Type', 'application/x-www-form-urlencoded');
const clientSecret = (this.keycloakConfig.credentials || {}).secret;
if (this.keycloakConfig.clientId && clientSecret) {
headers.set('Authorization', 'Basic ' + btoa(this.keycloakConfig.clientId + ':' + clientSecret));
}
return headers;
}
getRealmUrl(kc: any) {
if (kc && kc.authServerUrl) {
if (kc.authServerUrl.charAt(kc.authServerUrl.length - 1) == '/') {
return kc.authServerUrl + 'realms/' + encodeURIComponent(kc.realm);
} else {
return kc.authServerUrl + '/realms/' + encodeURIComponent(kc.realm);
}
} else {
return undefined;
}
}
}
第 3 步：然后您可以在组件中根据需要使用此服务。
@Component({
selector: 'page-enrolment',
templateUrl: 'enrolment-page.component.html'
})
export class EnrolmentPageComponent {
constructor(
public storage: StorageService,
private authService: AuthService,
) {}
goToRegistration() {
this.loading = true;
this.authService.keycloakLogin(false)
.then(() => {
return this.authService.retrieveUserInformation(this.language)
});
}
}
注意：keycloakLogin(true) 带您进入登录页面或 keycloakLogin(false) 带您进入 keycloak 注册页面。
我希望这或多或少能帮助你解决这个问题。
对于那些有类似问题的人，我写了一个关于它的库，它仅适用于Android和IOS平台，以使用Keycloak进行登录。这应该可以正常工作。
这也可以维持用户会话。尝试一下吧。
我最近在使用我的普通 Cordova 应用程序时遇到了类似的问题。我能够将用户重定向到 Keycloak 登录页面，但返回 Cordova 应用程序后没有任何反应。我的初始化代码如下所示，
keycloak.init({
onLoad: "check-sso",
adapter: 'cordova-native',
redirectUri: 'https://mywebsite.for-universal.link',
checkLoginIframe : false
});我的结论是 Deeplink 工作正常，因为我的应用程序在重定向到 Deeplink url 后打开。但不知何故，适配器无法检测到与深层链接 url 一起发送回应用程序的参数。
当我检查 keycloak.js 适配器实现时，我了解到 keycloak 特别期望从 Deeplink 插件触发“keycloak”事件。
所以，我在通用链接配置中添加了事件名称，
<universal-links>
<host name="mywebsite.for-universal.link" scheme="https" event="keycloak">
<path url="*" />
</host>
</universal-links>现在效果很好。希望它对某人有帮助。
此 API 的问题是无法使用电容器配置路由。
