要集成QQ账号登录,需要使用QQ提供的SDK,并在应用中注册一个QQ互联开放平台的应用,获取到应用ID和App Key。以下是Java代码示例:
1. 在pom.xml中添加依赖:
```xml
<dependency>
<groupId>com.tencent</groupId>
<artifactId>qqconnectapi</artifactId>
<version>5.0.0</version>
</dependency>
```
2. 在应用中注册QQ互联开放平台的应用,并获取到应用ID和App Key。
3. 创建一个QQ登录工具类,代码如下:
```java
import com.qq.connect.QQConnectException;
import com.qq.connect.api.QQConnect;
import com.qq.connect.api.qzone.UserInfo;
import com.qq.connect.oauth.Oauth;
import com.qq.connect.utils.QQConnectConfig;
import com.qq.connect.utils.http.DefaultHttpClient;
import com.qq.connect.utils.http.HttpClient;
import com.qq.connect.utils.http.HttpRequest;
import com.qq.connect.utils.http.HttpResponse;
import java.io.IOException;
public class QQLoginUtil {
private static final String QQ_APP_ID = "你的QQ应用ID";
private static final String QQ_APP_KEY = "你的QQ应用App Key";
private static final String REDIRECT_URI = "http://你的回调地址";
private static final QQConnect qqConnect = new QQConnect(QQ_APP_ID, QQ_APP_KEY);
/**
* 获取QQ登录授权URL
* @return QQ登录授权URL
* @throws QQConnectException
*/
public static String getAuthorizationUrl() throws QQConnectException {
return new Oauth().getAuthorizeURL(qqConnect, REDIRECT_URI);
}
/**
* 获取QQ用户信息
* @param accessToken
* @param openId
* @return QQ用户信息
* @throws QQConnectException
* @throws IOException
*/
public static QQUserInfo getQQUserInfo(String accessToken, String openId) throws QQConnectException, IOException {
QQConnectConfig.updateProperties(QQ_APP_ID, QQ_APP_KEY, REDIRECT_URI);
HttpClient httpClient = new DefaultHttpClient();
HttpRequest request = new HttpRequest(HttpRequest.METHOD_GET);
request.setUrl("https://graph.qq.com/user/get_user_info");
request.addParameter("access_token", accessToken);
request.addParameter("oauth_consumer_key", QQ_APP_ID);
request.addParameter("openid", openId);
request.addParameter("format", "json");
HttpResponse response = httpClient.execute(request);
String result = response.getResponseAsString();
return QQUserInfo.fromJson(result);
}
/**
* 获取QQ用户OpenID
* @param accessToken
* @return QQ用户OpenID
* @throws QQConnectException
*/
public static String getQQOpenId(String accessToken) throws QQConnectException {
return new Oauth().getOpenID(qqConnect, accessToken);
}
/**
* 获取QQ用户信息
* @param accessToken
* @param openId
* @return QQ用户信息
* @throws QQConnectException
*/
public static UserInfo getQQZoneUserInfo(String accessToken, String openId) throws QQConnectException {
return new UserInfo(accessToken, openId).getUserInfo();
}
}
```
4. 创建一个QQ用户信息实体类,代码如下:
```java
import com.alibaba.fastjson.JSON;
public class QQUserInfo {
private String nickname;
private String gender;
private String province;
private String city;
private String figureurl_qq_1;
public static QQUserInfo fromJson(String json) {
return JSON.parseObject(json, QQUserInfo.class);
}
// getter and setter
}
```
5. 在登录页面中添加QQ登录入口,代码如下:
```html
<a href="<%=QQLoginUtil.getAuthorizationUrl()%>">使用QQ账号登录</a>
```
6. 在回调页面中获取QQ用户信息,代码如下:
```java
import com.qq.connect.QQConnectException;
import com.qq.connect.api.qzone.UserInfo;
import com.qq.connect.oauth.Oauth;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
public class QQLoginCallbackServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
String accessToken = null;
String openId = null;
try {
accessToken = new Oauth().getAccessTokenByQueryString(req.getQueryString(), QQLoginUtil.REDIRECT_URI).getAccessToken();
openId = QQLoginUtil.getQQOpenId(accessToken);
QQUserInfo qqUserInfo = QQLoginUtil.getQQUserInfo(accessToken, openId);
UserInfo qqZoneUserInfo = QQLoginUtil.getQQZoneUserInfo(accessToken, openId);
// 处理QQ用户信息
} catch (QQConnectException e) {
e.printStackTrace();
}
// 跳转到首页
resp.sendRedirect("/");
}
}
```
以上就是Java集成QQ账号登录的详细代码。需要注意的是,这里只提供了最基本的代码示例,实际项目中还需要对代码进行优化和完善,比如错误处理、参数校验、安全性等方面的考虑。
