问题描述
我正在尝试使用SocialAuth，这个想法非常简单，在Facebook的log in中单击，然后将用户重定向到我登录的网站.我得到了log in部分，它在下面:
1)/index.xhtml
<h:form id="login-facebook">
<h:commandButton id="login" action="#{socialFacebook.login}" value="Login"/>
</h:form>
2)socialFacebook豆
package controller;
@ManagedBean(name="socialFacebook")
@RequestScoped
public class SocialFacebook implements Serializable{
private static final long serialVersionUID = -4787254243136316495L;
private String code;
@PostConstruct
public void init(){
try {
HttpServletRequest request=(HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
SocialAuthManager manager = (SocialAuthManager)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("authManager");
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);
AuthProvider provider = manager.connect(paramsMap);
// get profile
Profile p = provider.getUserProfile();
System.out.println(p.getFullName());
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void login(){
try {
HttpServletRequest request=(HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
//Create an instance of SocialAuthConfig object
SocialAuthConfig config = SocialAuthConfig.getDefault();
//load configuration. By default load the configuration from oauth_consumer.properties.
//You can also pass input stream, properties object or properties file name.
config.load();
//Create an instance of SocialAuthManager and set config
SocialAuthManager manager = new SocialAuthManager();
manager.setSocialAuthConfig(config);
//URL of YOUR application which will be called after authentication
//String successUrl = "http://localhost:8080/cc/pages/system/login_facebook.xhtml" + ";jsessionid=" + req.getSession().getId();
String successUrl = "http://localhost:8080/cc/pages/system/index.xhtml" + ";jsessionid=" + request.getSession().getId();
// get Provider URL to which you should redirect for authentication.
// id can have values "facebook", "twitter", "yahoo" etc. or the OpenID URL
String url = manager.getAuthenticationUrl("facebook", successUrl);
// Store in session
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("authManager", manager);
//redirect to the successful login page
FacesContext.getCurrentInstance().responseComplete();
FacesContext.getCurrentInstance().getExternalContext().redirect(url);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
}
3)Facebook返回了以下URL:
http://localhost:8080/cc/pages/system/home_facebook.xhtml;jsessionid=e143aa975fa3f313c677fbcb03e3?code=AQAmJXdQX0B__zJHXnRyPfgaG1CfNUEEEEEEEEEEEEEEEZJLEpsT5s1spd3KtWGWI2HYaIOZKLkrn8axKs4iKwJVQJwJQB_WSs2iWkp2DDDDDDDDDDDDtdRPLPG7psp6r2PYmn7CTm2QNNha7f1QlgmoZtBsIEF0SSSSSSSSSSSSSSSSSSSSSSS8RutAU8dqI2KDE57f#_=_
4)它按照BalusC的建议通过了我的init方法，但始终打印nope :(:
@ManagedBean(name="redirectFacebook")
@RequestScoped
public class RedirectFacebook implements Serializable{
private static final long serialVersionUID = -566276017320074630L;
private String code;
private Profile profile;
@PostConstruct
public void init(){
try {
HttpServletRequest request=(HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
HttpSession session = (HttpSession) request.getAttribute("jsessionid");
if (request.getAttribute("code") != null)
System.out.println("code");
else
System.out.println("nope :(");
if (session != null){
SocialAuthManager manager = (SocialAuthManager)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("authManager");
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);
AuthProvider provider = manager.connect(paramsMap);
// get profile
profile = provider.getUserProfile();
System.out.println(profile.getFullName());
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
5)并且在我的home_facebook页面上也打印nope :(:
<h:form id="redirect-facebook-form">
<f:metadata>
<f:viewParam name="code" value="#{redirectFacebook.code}" />
</f:metadata>
<h:panelGroup rendered="#{not empty redirectFacebook.profile}">
Hello, you're successfully associated as #{socialFacebook.profile.firstName} on Facebook
</h:panelGroup>
<h:panelGroup rendered="#{empty redirectFacebook.profile}">
Nope :(
</h:panelGroup>
</h:form>
但是，我有点困惑如何在我的bean中获得结果并进行一些验证，就像是否注册了用户一样.我知道，在Google中查看一些代码后，我必须这样做，但是如何才能重定向到我的bean并执行此操作，并将用户重定向到正确的页面?
SocialAuthManager manager = (SocialAuthManager)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("authManager");
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);
AuthProvider provider = manager.connect(paramsMap);
// get profile
Profile p;
p = provider.getUserProfile();
这真的要花一些晚上才能弄清楚.任何想法都很赞赏，谢谢.
解决方案
除了您在URL中使用localhost之外，我没有看到任何代码级问题.这是 Wiki链接，其中描述了如何使用localhost运行应用程序. /p>
请告诉我这是否无效.
I'm trying to use SocialAuth, the idea is very simple, click in log in with facebook then redirect the user to my website signed in.The log in part I get it, which is below :
1) /index.xhtml
<h:form id="login-facebook">
<h:commandButton id="login" action="#{socialFacebook.login}" value="Login"/>
</h:form>
2) socialFacebook bean
package controller;
@ManagedBean(name="socialFacebook")
@RequestScoped
public class SocialFacebook implements Serializable{
private static final long serialVersionUID = -4787254243136316495L;
private String code;
@PostConstruct
public void init(){
try {
HttpServletRequest request=(HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
SocialAuthManager manager = (SocialAuthManager)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("authManager");
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);
AuthProvider provider = manager.connect(paramsMap);
// get profile
Profile p = provider.getUserProfile();
System.out.println(p.getFullName());
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void login(){
try {
HttpServletRequest request=(HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
//Create an instance of SocialAuthConfig object
SocialAuthConfig config = SocialAuthConfig.getDefault();
//load configuration. By default load the configuration from oauth_consumer.properties.
//You can also pass input stream, properties object or properties file name.
config.load();
//Create an instance of SocialAuthManager and set config
SocialAuthManager manager = new SocialAuthManager();
manager.setSocialAuthConfig(config);
//URL of YOUR application which will be called after authentication
//String successUrl = "http://localhost:8080/cc/pages/system/login_facebook.xhtml" + ";jsessionid=" + req.getSession().getId();
String successUrl = "http://localhost:8080/cc/pages/system/index.xhtml" + ";jsessionid=" + request.getSession().getId();
// get Provider URL to which you should redirect for authentication.
// id can have values "facebook", "twitter", "yahoo" etc. or the OpenID URL
String url = manager.getAuthenticationUrl("facebook", successUrl);
// Store in session
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("authManager", manager);
//redirect to the successful login page
FacesContext.getCurrentInstance().responseComplete();
FacesContext.getCurrentInstance().getExternalContext().redirect(url);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
}
3) Facebook returned the following URL:
http://localhost:8080/cc/pages/system/home_facebook.xhtml;jsessionid=e143aa975fa3f313c677fbcb03e3?code=AQAmJXdQX0B__zJHXnRyPfgaG1CfNUEEEEEEEEEEEEEEEZJLEpsT5s1spd3KtWGWI2HYaIOZKLkrn8axKs4iKwJVQJwJQB_WSs2iWkp2DDDDDDDDDDDDtdRPLPG7psp6r2PYmn7CTm2QNNha7f1QlgmoZtBsIEF0SSSSSSSSSSSSSSSSSSSSSSS8RutAU8dqI2KDE57f#_=_
4) It pass by my init method as BalusC suggest but always prints nope :( :
@ManagedBean(name="redirectFacebook")
@RequestScoped
public class RedirectFacebook implements Serializable{
private static final long serialVersionUID = -566276017320074630L;
private String code;
private Profile profile;
@PostConstruct
public void init(){
try {
HttpServletRequest request=(HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
HttpSession session = (HttpSession) request.getAttribute("jsessionid");
if (request.getAttribute("code") != null)
System.out.println("code");
else
System.out.println("nope :(");
if (session != null){
SocialAuthManager manager = (SocialAuthManager)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("authManager");
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);
AuthProvider provider = manager.connect(paramsMap);
// get profile
profile = provider.getUserProfile();
System.out.println(profile.getFullName());
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
5) And it prints nope :( too in my home_facebook page:
<h:form id="redirect-facebook-form">
<f:metadata>
<f:viewParam name="code" value="#{redirectFacebook.code}" />
</f:metadata>
<h:panelGroup rendered="#{not empty redirectFacebook.profile}">
Hello, you're successfully associated as #{socialFacebook.profile.firstName} on Facebook
</h:panelGroup>
<h:panelGroup rendered="#{empty redirectFacebook.profile}">
Nope :(
</h:panelGroup>
</h:form>
But, I'm a bit confuse how to get the result in my bean and do some verifications as if the user is registered or not for instance. I know, looking some code in Google, that I have to do this, but how can I redirect to my bean and do this and redirect the user to the proper page ?
SocialAuthManager manager = (SocialAuthManager)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("authManager");
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);
AuthProvider provider = manager.connect(paramsMap);
// get profile
Profile p;
p = provider.getUserProfile();
This is really taking some nights to figure it out.Any idea is very appreaciated, thanks.
解决方案
I don't see any code level issue except you are using localhost in URL.Here is a wiki link which describes how to run application with localhost.
Please let me know if this does not work.
