CAS Server集成QQ第三方登录，CAS Server集成新浪微博第三方登录以及CAS Server集成微信网页登录源码和配置基本类似，本文着重介绍一下如何通过CAS Server（cas-server3.5.2）实现qq第三方登录，并分享一下实现代码和具体配置文件内容，虽然包含新浪微博登录但是未经测试，有什么疑问可留言。
首先简单介绍一下CAS Server，它是一套基于Java实现的服务，该服务以一个Java Web Application单独部署在与servlet2.3兼容的Web服务器上。由于CAS Client与CAS Server之间的交互采用Https协议，因此部署CAS Server的服务器还需要支持SSL协议。当SSL配置成功过后，像普通Web应用一样将CAS Server部署在服务器上就能正常运行了，也可通过手动修改配置取消对SSL协议的支持。
cas-server集成QQ第三方登录
1、打开cas-server工程中cas-server-support-oauth子项目，创建QQApi20.java类文件名称并继承DefaultApi20.java类，具体代码如下：
package org.jasig.cas.support.oauth.qq;
import org.jasig.cas.support.oauth.OAuthConstants;
import org.scribe.builder.api.DefaultApi20;
import org.scribe.model.OAuthConfig;
import org.scribe.utils.OAuthEncoder;
public class QQApi20 extends DefaultApi20 {
private static String serverUrl = "";
@Override
public String getAccessTokenEndpoint() {
return serverUrl + "/" + OAuthConstants.QQ_ACCESS_TOKEN_URL + "?grant_type=authorization_code";
}
@Override
public String getAuthorizationUrl(final OAuthConfig config) {
return String.format(serverUrl + "/" + OAuthConstants.AUTHORIZE_URL
+ "?client_id=%s&redirect_uri=%s&response_type=code", config.getApiKey(),
OAuthEncoder.encode(config.getCallback()));
}
public static void setServerUrl(final String url) {
serverUrl = url;
}
}
2、创建QQProvider.java类文件名称并继承BaseOAuth20Provider.java类，具体代码如下：
package org.jasig.cas.support.oauth.qq;import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;import org.apache.commons.httpclient.DefaultHttpMethodRetryHandler;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.params.HttpMethodParams;
import org.jasig.cas.support.oauth.OAuthConstants;
import org.jasig.cas.support.oauth.entity.UserInfo;
import org.jasig.cas.support.oauth.profile.QQWrapperProfile;
import org.scribe.builder.ServiceBuilder;
import org.scribe.model.Token;
import org.scribe.up.profile.JsonHelper;
import org.scribe.up.profile.UserProfile;
import org.scribe.up.provider.BaseOAuth20Provider;
import org.scribe.up.provider.BaseOAuthProvider;
import org.springframework.orm.jpa.JpaTemplate;import com.fasterxml.jackson.databind.JsonNode;/**
* This class is the OAuth provider to authenticate user in CAS server wrapping OAuth protocol.
*
* @author Jerome Leleu
* @since 3.5.0
*/
public final class QQProvider extends BaseOAuth20Provider {
private String serverUrl;
private JpaTemplate jpaTemplate;
@Override
protected void internalInit() {
QQApi20.setServerUrl(this.serverUrl);
this.service = new ServiceBuilder().provider(QQApi20.class).apiKey(this.key).apiSecret(this.secret)
.callback(this.callbackUrl).build();
}
@Override
protected String getProfileUrl() {
return this.serverUrl + "/" + OAuthConstants.QQ_PROFILE_URL;
}
@Override
protected UserProfile extractUserProfile(final String body) {
final QQWrapperProfile userProfile = new QQWrapperProfile();
String str = body.replace("callback( ", "").replace(" );", "");
JsonNode json = JsonHelper.getFirstNode(str);
userProfile.setId(JsonHelper.get(json, QQWrapperProfile.ID));
userProfile.addAttribute(QQWrapperProfile.CLIENTID, JsonHelper.get(json, QQWrapperProfile.CLIENTID));
return userProfile;
}private static String getRandomStr(){
SimpleDateFormat formatter = new SimpleDateFormat ("MMddHHmmss");
Date curDate = new Date(System.currentTimeMillis());//获取当前时间
String str = formatter.format(curDate);
String cur = str.substring(0,2);
String cur2 = str.substring(2,4);
String temp = (Integer.parseInt(cur)+Integer.parseInt(cur2))+""+str.substring(4);
int cur_id = Integer.parseInt(temp.substring(0,4))+Integer.parseInt(temp.substring(4));
String randomstr ="y" + cur_id + (int)(Math.random()*10000);
return randomstr;
}
@SuppressWarnings({ "deprecation", "rawtypes" })
@Override
protected UserProfile getUserProfile(final Token accessToken) {
final String body = sendRequestForData(accessToken, getProfileUrl());
if (body == null) {
return null;
}
final UserProfile profile = extractUserProfile(body);
addAccessTokenToProfile(profile, accessToken);
String url = "https://graph.qq.com/user/get_user_info?access_token="+accessToken.getToken()+"&oauth_consumer_key="+this.key+"&openid="+profile.getId();
String response = getHttp(url);
JsonNode json = JsonHelper.getFirstNode(response);
String ret = json.get("ret").asText();
if(ret != null && ret.equals("0")){
List list = jpaTemplate.find("from UserInfo where openid='"+profile.getId()+"'");
UserInfo userInfo = null;
if(list == null || list.isEmpty()){
userInfo = new UserInfo();
String nickName = json.get("nickname").asText();
nickName = nickName.replaceAll("[^0-9a-zA-Z\\u4e00-\\u9fa5]", "");
userInfo.setNickName(nickName);
userInfo.setAvatar(json.get("figureurl_qq_1").asText());
userInfo.setGender(json.get("gender").asText());
userInfo.setOpenId(profile.getId());
userInfo.setClientId((String)profile.getAttributes().get(QQWrapperProfile.CLIENTID));
userInfo.setUserName(getRandomStr());
userInfo.setCompleted(0);
if(userInfo.getNickName() == null || userInfo.getNickName().equals("")){
userInfo.setNickName(userInfo.getUserName());
}
userInfo.setCreateTime(new Date());
jpaTemplate.persist(userInfo);
}else{
userInfo = (UserInfo) list.get(0);
userInfo.setUpdateTime(new Date());
jpaTemplate.merge(userInfo);
}
profile.setId(userInfo.getUserName());
profile.addAttribute("userId",userInfo.getUserId());
profile.addAttribute("userName",userInfo.getUserName());
profile.addAttribute("nickName",userInfo.getNickName());
profile.addAttribute("avatar",userInfo.getAvatar());
profile.addAttribute("gender",userInfo.getGender());
profile.addAttribute("openId",userInfo.getOpenId());
profile.addAttribute("clientId",userInfo.getClientId());
profile.addAttribute("completed",userInfo.getCompleted());
}
return profile;
}
public static String getHttp(String url) {
String responseMsg = "";
HttpClient httpClient = new HttpClient();
GetMethod getMethod = new GetMethod(url);
getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,new DefaultHttpMethodRetryHandler());
try {
httpClient.executeMethod(getMethod);
ByteArrayOutputStream out = new ByteArrayOutputStream();
InputStream in = getMethod.getResponseBodyAsStream();
int len = 0;
byte[] buf = new byte[1024];
while((len=in.read(buf))!=-1){
out.write(buf, 0, len);
}
responseMsg = out.toString("UTF-8");
} catch (HttpException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
//释放连接
getMethod.releaseConnection();
}
return responseMsg;
}
public void setServerUrl(final String serverUrl) {
this.serverUrl = serverUrl;
}
@Override
protected BaseOAuthProvider newProvider() {
final QQProvider newProvider = new QQProvider();
newProvider.setServerUrl(this.serverUrl);
return newProvider;
}public JpaTemplate getJpaTemplate() {
return jpaTemplate;
}public void setJpaTemplate(JpaTemplate jpaTemplate) {
this.jpaTemplate = jpaTemplate;
}
}
3、在cas-server-webapp子项目中，打开applicationContext.xml文件，添加对应的oauth的clients信息并把clients增加到对应的org.pac4j.core.client.Clients中，具体配置内容下：
<bean id="sinaWeibo" class="org.jasig.cas.support.oauth.sina.SinaWeiboProvider">
<property name="key" value="xxxxxxxxxxxxxxxx" />
<property name="secret" value="xxxxxxxxxxxxxxxxxxxxxxxxxxxx" />
<property name="serverUrl" value="https://api.weibo.com/oauth2"/>
<property name="callbackUrl" value="http://api.yoodb.com" /> <!-- oauth10login -->
</bean>
<bean id="qq" class="org.jasig.cas.support.oauth.qq.QQProvider"><!--新浪微博bean配置，跳过-->
<property name="jpaTemplate" ref="jpaTemplate"/>
<property name="key" value="xxxxxxxxxxxx" />
<property name="secret" value="xxxxxxxxxxxxxxxxxxxx" />
<property name="serverUrl" value="https://graph.qq.com/oauth2.0"/>
<property name="callbackUrl" value="http://api.yoodb.com" /> <!-- oauth10login -->
</bean>
4、在cas-server-webapp子项目中，打开deployerConfigContext.xml文件，增加bean配置，具体配置内容下：
<bean class="org.jasig.cas.support.oauth.OAuthConfiguration" id="oAuthConfiguration">
<property name="loginUrl" value="http://api.yoodb.com"/>
<property name="providers">
<list>
<ref bean="sinaWeibo" /><!--新浪微博配置，跳过-->
<ref bean="qq" />
</list>
</property>
</bean>
5、添加以下链接到登录页面casLoginView.jsp(ClientNameUrl这个属性是被OAuthConfiguration自动创建)，也就是你自定义的Client类名加上Url。如我创建的类为QQProvider则对应的link名为QQProviderUrl，具体代码如下：
<div class="row btn-row third-part">
<p class="third_login"><span>第三方帐号登录</span></p>
<a href="${QQProviderUrl}" class="qq"></a>
<a href="javascript:alert('目前只有QQ登录可以使用！');" class="sina"></a>
<%-- <a href="${SinaWeiboProviderUrl}" class="sina"></a> --%>
<a href="javascript:alert('目前只有QQ登录可以使用！');" class="baidu"></a>
<a href="javascript:alert('目前只有QQ登录可以使用！');" class="wechat"></a>
</div>
cas-server集成新浪微博第三方登录
1、打开cas-server工程中cas-server-support-oauth子项目，创建SinaWeiboApi20.java类文件名称并继承DefaultApi20.java类，具体代码如下：
package org.jasig.cas.support.oauth.sina;import org.jasig.cas.support.oauth.OAuthConstants;
import org.scribe.builder.api.DefaultApi20;
import org.scribe.model.OAuthConfig;
import org.scribe.utils.OAuthEncoder;public class SinaWeiboApi20 extends DefaultApi20 {
private static String serverUrl = "";@Override
public String getAccessTokenEndpoint() {
return serverUrl + "/" + OAuthConstants.SINA_ACCESS_TOKEN_URL + "?";
}@Override
public String getAuthorizationUrl(final OAuthConfig config) {
return String.format(serverUrl + "/" + OAuthConstants.AUTHORIZE_URL
+ "?client_id=%s&redirect_uri=%s&response_type=code", config.getApiKey(),
OAuthEncoder.encode(config.getCallback()));
}public static void setServerUrl(final String url) {
serverUrl = url;
}
}
2、创建SinaWeiboProvider.java类文件名称并继承BaseOAuth20Provider.java类，具体代码如下：
package org.jasig.cas.support.oauth.sina;import java.util.Iterator;import org.jasig.cas.support.oauth.OAuthConstants;
import org.jasig.cas.support.oauth.profile.CasWrapperProfile;
import org.scribe.builder.ServiceBuilder;
import org.scribe.up.profile.JsonHelper;
import org.scribe.up.profile.UserProfile;
import org.scribe.up.provider.BaseOAuth20Provider;
import org.scribe.up.provider.BaseOAuthProvider;import com.fasterxml.jackson.databind.JsonNode;/**
* This class is the OAuth provider to authenticate user in CAS server wrapping OAuth protocol.
*
* @author Jerome Leleu
* @since 3.5.0
*/
public final class SinaWeiboProvider extends BaseOAuth20Provider {
private String serverUrl;
@Override
protected void internalInit() {
SinaWeiboApi20.setServerUrl(this.serverUrl);
this.service = new ServiceBuilder().provider(SinaWeiboApi20.class).apiKey(this.key).apiSecret(this.secret)
.callback(this.callbackUrl).build();
}
@Override
protected String getProfileUrl() {
return this.serverUrl + "/" + OAuthConstants.SINA_PROFILE_URL;
}
@Override
protected UserProfile extractUserProfile(final String body) {
final CasWrapperProfile userProfile = new CasWrapperProfile();
JsonNode json = JsonHelper.getFirstNode(body);
if (json != null) {
userProfile.setId(JsonHelper.get(json, CasWrapperProfile.ID));
json = json.get(CasWrapperProfile.ATTRIBUTES);
if (json != null) {
final Iterator<JsonNode> nodes = json.iterator();
while (nodes.hasNext()) {
json = nodes.next();
final String attribute = json.fieldNames().next();
userProfile.addAttribute(attribute, JsonHelper.get(json, attribute));
}
}
}
return userProfile;
}
public void setServerUrl(final String serverUrl) {
this.serverUrl = serverUrl;
}
@Override
protected BaseOAuthProvider newProvider() {
final SinaWeiboProvider newProvider = new SinaWeiboProvider();
newProvider.setServerUrl(this.serverUrl);
return newProvider;
}
}
cas-server集成新浪微博登录和在cas-server集成qq登录类似，参考一下（本文中已经增加新浪微博配置及步骤但未经过测试），此处省略。
