如果要取得 OAuth 授權的話,可以直接使用 OkHttpClient 或是 OAuth2RestTemplate 來實作
在依賴中增加 OkHttpClient
build.gradle
dependencies { compile ‘com.squareup.okhttp3:okhttp:3.6.0‘ }
實際登入的程式
public void Okhttp() throws IOException { OkHttpClient client = new OkHttpClient(); String credential = Credentials.basic("clientkpi", "123456"); FormBody body = new FormBody.Builder() .add("username", "sam.chu=") .add("password", "12345678") .add("grant_type", "password") .add("scope", "account role").build(); Request request = new Request.Builder() .header("Authorization", credential) .url("http://localhost:8081/oauth/token") .post(body) .build(); try (Response response = client.newCall(request).execute()) { if (!response.isSuccessful()) { throw new IOException("Unexpected code " + response); } ObjectMapper mapper = new ObjectMapper(); OauthToken oauthToken = mapper.readValue(response.body().string(), OauthToken.class); System.out.println(oauthToken); } }
或是你可以選 org.springframework.security.oauth:spring-security-oauth2 提供的 OAuth2RestTemplate
在依賴中增加 org.springframework.security.oauth:spring-security-oauth2
build.gradle
dependencies { compile(‘org.springframework.boot:spring-boot-starter-security‘) compile ‘org.springframework.security.oauth:spring-security-oauth2:2.0.12.RELEASE‘ }
public void testOAuth() { AccessTokenRequest atr = new DefaultAccessTokenRequest(); OAuth2RestTemplate oAuth2RestTemplate = new OAuth2RestTemplate(resource(), new DefaultOAuth2ClientContext(atr)); try { System.out.println(oAuth2RestTemplate.getAccessToken()); System.out.println(oAuth2RestTemplate.getAccessToken().getRefreshToken()); } catch (OAuth2AccessDeniedException e) { System.out.println("登入失敗" + e.getHttpErrorCode()); // 403 System.out.println("登入失敗" + e.getOAuth2ErrorCode()); // access_denied System.out.println("登入失敗" + e.getMessage()); //Access token denied. System.out.println("登入失敗" + e.getLocalizedMessage()); // Access token denied. System.out.println("登入失敗" + e.getSummary()); // error="access_denied", error_description="Access token denied." } } protected OAuth2ProtectedResourceDetails resource() { ResourceOwnerPasswordResourceDetails resource = new ResourceOwnerPasswordResourceDetails(); List scopes = new ArrayList<String>(2); scopes.add("account"); scopes.add("role"); resource.setAccessTokenUri("http://localhost:8081/oauth/token"); resource.setClientId("clientkpi"); resource.setClientSecret("123456"); resource.setGrantType("password"); resource.setScope(scopes); resource.setUsername("sam.chu="); resource.setPassword("12345678"); return resource; }
不過基於 Spring Boot 的自動配置會亂數產生帳密 來做 Http basic 認證,剛開發的時候會有點煩
可以在 SpringBootApplication 暫時把它關閉
順便把 EnableOAuth2Client 加上
@EnableOAuth2Client @SpringBootApplication(exclude = {SecurityAutoConfiguration.class}) public class KpiApplication { public static void main(String[] args) { SpringApplication.run(KpiApplication.class, args); } }
其他兩個範例是使用 RestTemplate 來新增跟取得的範例
public void restPost() throws IOException { String url = "http://localhost:8082/api/v1/role"; RestTemplate restTemplate = new RestTemplate(); HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_JSON_UTF8); headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON_UTF8)); headers.add("Authorization", String.format("%s %s", "bearer", "eyJhbGciOiJIUzI1.NiIsInR5cCI6I.kpXVCJ9")); RoleDto roleDto = new RoleDto(); roleDto.setCode("ROLE_GINTAMA"); roleDto.setLabel("銀魂銀魂銀魂"); HttpEntity<RoleDto> entity = new HttpEntity<RoleDto>(roleDto, headers); ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, entity, String.class, new HashMap<String, String>()); if (response.getStatusCode().equals(HttpStatus.CREATED)) { System.out.println(response.getBody()); } }
取得資源
public void restGet() throws IOException { String url = "http://localhost:8082/api/v1/role"; RestTemplate restTemplate = new RestTemplate(); HttpHeaders headers = new HttpHeaders(); headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON_UTF8)); headers.add("Authorization", String.format("%s %s", "bearer", "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsia3BpIiwiYWNjb3VudCJdLCJ1c2VyX25hbWUiOiJzYW0uY2h1PSIsInNjb3BlIjpbImFjY291bnQiLCJyb2xlIl0sImV4cCI6MTQ4NzU3NDUzNywiYXV0aG9yaXRpZXMiOlsiUk9MRV9VU0VSIl0sImp0aSI6ImNiMzc0OGFmLTc2NGUtNDNiNy1iNTVjLTU4ZjQzZWQwOTU0MCIsImNsaWVudF9pZCI6ImNsaWVudGtwaSJ9.9Wwk5-GrJ_xdVOcOexoDhIXEznHqm3ssBfob0FeSFgA")); HttpEntity<String> entity = new HttpEntity<String>(headers); ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, entity, String.class); if (response.getStatusCode().equals(HttpStatus.OK)) { System.out.println(response.getBody()); } }
← use JWT OAuth2 and spring-security Create AuthorizationServer
