我刚刚开始学习oAuth2授权来保护我的API。而且这个过程非常复杂。我的API是使用Jersey开发的,而Apache Oltu是使用oAuth2授权开发的。现在,可以生成令牌,但是,每次我尝试生成新令牌时,服务器都会创建一个@ApplicationScoped bean的新实例。 这是我从互联网上获得的bean代码:
@ApplicationScoped
public class Database {
private Set<String> authCodes = new HashSet<>();
private Set<String> tokens = new HashSet<>();
public void addAuthCode(String authCode) {
authCodes.add(authCode);
}
public boolean isValidAuthCode(String authCode) {
return authCodes.contains(authCode);
}
public void addToken(String token) {
tokens.add(token);
}
public boolean isValidToken(String token) {
return tokens.contains(token);
}
}
这是授权码:
@Path("/authz")
public class AuthzEndpoint {
@Inject
Database database;
@GET
public Response authorize(@Context HttpServletRequest request)
throws URISyntaxException, OAuthSystemException {
try {
OAuthAuthzRequest oauthRequest = new OAuthAuthzRequest(request);
OAuthIssuerImpl oauthIssuerImpl = new OAuthIssuerImpl(new MD5Generator());
//build response according to response_type
String responseType = oauthRequest.getParam(OAuth.OAUTH_RESPONSE_TYPE);
OAuthASResponse.OAuthAuthorizationResponseBuilder builder =
OAuthASResponse.authorizationResponse(request, HttpServletResponse.SC_FOUND);
if (responseType.equals(ResponseType.CODE.toString())) {
final String authorizationCode = oauthIssuerImpl.authorizationCode();
database.addAuthCode(authorizationCode);
builder.setCode(authorizationCode);
}
if (responseType.equals(ResponseType.TOKEN.toString())) {
final String accessToken = oauthIssuerImpl.accessToken();
database.addToken(accessToken);
builder.setAccessToken(accessToken);
builder.setExpiresIn(3600l);
}
String redirectURI = oauthRequest.getParam(OAuth.OAUTH_REDIRECT_URI);
final OAuthResponse response = builder.location(redirectURI).buildQueryMessage();
URI url = new URI(response.getLocationUri());
return Response.status(response.getResponseStatus()).location(url).build();
} catch (OAuthProblemException e) {
final Response.ResponseBuilder responseBuilder = Response.status(HttpServletResponse.SC_FOUND);
String redirectUri = e.getRedirectUri();
if (OAuthUtils.isEmpty(redirectUri)) {
throw new WebApplicationException(
responseBuilder.entity("OAuth callback url needs to be provided by client!!!").build());
}
final OAuthResponse response =
OAuthASResponse.errorResponse(HttpServletResponse.SC_FOUND)
.error(e).location(redirectUri).buildQueryMessage();
final URI location = new URI(response.getLocationUri());
return responseBuilder.location(location).build();
}
}
}
如你所见,那里有@Inject数据库注释,并在代码的某些部分调用了addToken()方法。当我尝试从我的主Web服务验证令牌时,数据库bean是空的。这是代码
@Inject
Database database;
@POST
@Path("validateLogin")
@Consumes("application/x-www-form-urlencoded")
@Produces({"application/xml", "application/json", "text/plain", "text/html"})
public Response validateLogin(@HeaderParam("Authorization") String token, @FormParam("username") String username, @FormParam("password") String password) {
System.out.println(token.substring(7,token.length()));
System.out.println(database.isValidToken(token.substring(7, token.length())));
System.out.println(database);
if (!database.isValidToken(token.substring(7, token.length()))) {
return Response.status(Response.Status.UNAUTHORIZED).build();
}
else {
String result;
if (username == null || password == null) {
return Response.status(Response.Status.BAD_REQUEST).build();
}
else {
STCWebService stcWebService = new STCWebService();
result = stcWebService.validateLogin(username,password);
if (result.isEmpty()) {
return Response.status(Response.Status.INTERNAL_SERVER_ERROR).build();
}
else {
return Response
.status(200)
.entity(result)
.type(MediaType.APPLICATION_JSON)
.header("Access-Control-Allow-Origin", "*")
.header("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT")
.build();
}
}
}
}
我一直认为web.xml文件或ResourceConfig.java或者甚至在ApplicationBinder中可能存在一些错误。几个小时我偶然发现了这个问题。任何帮助表示赞赏。
修改
这是ApplicationBinder代码
public class MyApplicationBinder extends AbstractBinder {
@Override
protected void configure() {
bind(Database.class).to(Database.class);
}
}
并链接到此MyApplication
public class MyApplication extends ResourceConfig {
public MyApplication() {
register(new MyApplicationBinder());
packages("com.package");
}
}
创建了ApplicationBinder和MyApplication代码
答案 0 :(得分:2)
问题是如何绑定Database
。
bind(Database.class).to(Database.class);
ApplicationScoped
无效。您需要使用AbstractBinder
配置范围。有几种方法。
只是实例化
bind(new Database()).to(Database.class);
这将自动使其成为单身人士。然而,一个问题是,如果Database
拥有它自己的依赖项,它们将不会被注入。这样,您可以使用下一个解决方案
使用in(Scope)
方法向服务添加范围。未提供时,默认范围为PerLookup
,这意味着每次请求时都会创建一个新范围。还有其他范围,例如Singleton
和RequestScope
bind(Database.class).to(Database.class).in(Singleton.class);
确保它是javax.inject.Singleton
而不是EJB。
