按照手册我实现连接到Facebook图形API和检索信息从用户。当我想要访问(登录)Facebook时,问题出现了,我得到了这个错误:

错误明确表示"不允许匿名用户获得访问令牌"。当然,用户是匿名的,并且正在尝试进行身份验证。那我该怎么做呢?也许我在控制器上做的不是正确的登录方式?
控制器:
@RequestMapping("/facebookLogin")
@ResponseBody
public User login() {
ObjectNode result = facebookRestTemplate
.getForObject(
"https://graph.facebook.com/me/?fields=name,email,third_party_id",
ObjectNode.class);
...
}
我使用spring-security:4.0.1.RELEASE
和spring-security-oauth2:2.0.7.RELEASE
注意:在这种情况下,我使用facebook,但问题也应该出现与谷歌,twitter等
您共享的代码片段不显示登录,它只在您试图检索有关用户的信息时显示。
根据Spring文档,您需要调整客户端以使其能够与FB一起工作。
一些外部OAuth2提供商(例如Facebook)并没有完全实现规范正确,否则他们只是卡在一个旧的版本的规范比Spring Security OAuth。要使用这些提供者在您的客户机应用程序中,您可能需要调整的各个部分客户端基础设施。
以Facebook为例,在Tonr2应用程序(您需要更改配置以添加您的拥有、有效、客户端id和秘密——它们很容易在Facebook网站)。
有一个关于如何在JSP (tomcat)中的Servlet页面Facebook Connect示例中的另一个线程的响应
这里是另一个解决方案的副本如何在MVC实现中做到这一点:
public ActionResult Authenticate()
{
var oauthFacebook = new FacebookOAuth();
if (Request["code"] == null)
{
//Redirect the user to Facebook for authorization.
Response.Redirect(oauthFacebook.AuthorizationLinkGet());
}
else
{
//Get the access token and secret.
oauthFacebook.AccessTokenGet(Request["code"]);
if (oauthFacebook.Token.Length > 0)
{
//We can now make our api calls
var user = oauthFacebook.GetAttributes();
}
}
}
public class FacebookOAuth : Oauth
{
public FacebookOAuth()
{
Authorize = "https://graph.facebook.com/oauth/authorize";
AccessToken = "https://graph.facebook.com/oauth/access_token";
CallbackUrl = "http://<YourURLHere>/Authenticate";
AttributesBaseUrl = "https://graph.facebook.com/me/?access_token=";
ConsumerKey = ConfigurationManager.AppSettings["FacebookConsumerKey"];//Ur Consumer Key goes here
ConsumerSecret = ConfigurationManager.AppSettings["FacebookConsumerSecret"];//Ur Consumer secret goes here
Provider = "Facebook";
}
public override string AuthorizationLinkGet()
{
return
string.Format(
"{0}?client_id={1}&redirect_uri={2}&scope=email,user_education_history,user_location,user_hometown",
Authorize, ConsumerKey, CallbackUrl);
}
public User GetAttributes()
{
string attributesUrl = string.Format("{0}{1}", AttributesBaseUrl, Token);
string attributes = WebRequest(Method.Get, attributesUrl, String.Empty);
var FacebookUser = new JavaScriptSerializer().Deserialize<FacebookUser>(attributes);
return new User()
{
FirstName = FacebookUser.first_name,
MiddleName = FacebookUser.middle_name,

NameValueCollection qs = HttpUtility.ParseQueryString(response);
if (qs["access_token"] != null)

}
}
}
public string WebRequest(Method method, string url, string postData)
{

var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;

希望有帮助!
在tonr2项目中检查这段代码
https://github.com/spring-projects/spring-security-oauth/blob/master/samples/oauth2/tonr/src/main/java/org/springframework/security/oauth/examples/config/WebMvcConfig.java@Bean
public OAuth2ProtectedResourceDetails facebook() {
AuthorizationCodeResourceDetails details = new AuthorizationCodeResourceDetails();
details.setId("facebook");
details.setClientId("233668646673605");
details.setClientSecret("33b17e044ee6a4fa383f46ec6e28ea1d");
details.setAccessTokenUri("https://graph.facebook.com/oauth/access_token");
details.setUserAuthorizationUri("https://www.facebook.com/dialog/oauth");
details.setTokenName("oauth_token");
details.setAuthenticationScheme(AuthenticationScheme.query);
details.setClientAuthenticationScheme(AuthenticationScheme.form);
return details;
}
在OAuth2ProtectedResourceDetails上相应地添加您的facebook凭据。然后,当您尝试从facebook获取数据时,Spring Security OAuth AuthenticationProvider将引用此bean,一旦FacebookController尝试访问FB数据,该数据将自动检测到。但是你必须理解下面的配置:
https://github.com/spring-projects/spring-security-oauth/blob/master/samples/oauth2/tonr/src/main/java/org/springframework/security/oauth/examples/config/SecurityConfig.java@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("marissa").password("wombat").roles("USER").and().withUser("sam")
.password("kangaroo").roles("USER");
}
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/resources/**");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
// @formatter:off
http.authorizeRequests()
.antMatchers("/sparklr/**","/facebook/**").hasRole("USER")
.anyRequest().permitAll()
.and()
.logout()
.logoutSuccessUrl("/login.jsp")
.permitAll()
.and()
.formLogin()
.loginProcessingUrl("/login")
.loginPage("/login.jsp")
.failureUrl("/login.jsp?authentication_error=true")
.permitAll();
// @formatter:on
}
}
假设您将使用tonr2应用程序,inMemoryAuthentication使用用户"marissa"和密码"wombat"提供Spring安全认证。因此,在您的ui中,尝试首先针对Spring Security进行身份验证。通过身份验证后,您将拥有"USER"角色。只有这一次,你将被允许访问名为FaceBookController的资源,它试图从facebook本身检索数据,参考这段代码,
http.authorizeRequests()
.antMatchers("/sparklr/**","/facebook/**").hasRole("USER")
.anyRequest().permitAll()
.and()
所以只需相应地调整代码。
注意:给定的Spring Security示例应用程序尚未配置为具有动态客户端密钥,它仍然使用OAuth2ProtectedResourceDetails中的单个密钥进行硬编码,只是为了简单演示。从经过身份验证的facebook用户获取动态facebook客户端秘密密钥需要更多的步骤。或者,如果您只想测试facebook检索,请将上面的代码调整为如下内容,
http.authorizeRequests()
.anyRequest().permitAll()
.and()
删除要求用户拥有user角色的限制,只允许所有请求,而不需要首先在Spring Security上进行身份验证。
