大家好,又见面了,我是你们的朋友全栈君。
Java实现QQ登录
写了一个个人网站,增加一个登录的地方,自己写登录太麻烦,而且用户一般也不愿意去登录,接入QQ互联,实现QQ一键登录。所有前提是你得有一个IP地址和域名。
==ps:==用处不大,主要是写着玩
1 进入qq互联官网进入点击头像个创建提交申请
2 选择个人接入,按照步骤填写注册资料
创建成功通过后会哦显示接入的个人信息。
3 审核成功后点击下面的开始创建,按步骤完成创建过程。
4 创建成功后可以查看APP ID
和APP key
,很重要
在应用管理界面可以查看如上信息,点击查看就可以看到如下关键信息。
往下划在平台信息里可以看到网站地址和网站回调域,回调域一般是`@requestMapping()“中写的请求地址
5 登录页面
<a href"/login">qq登录</a>
6 配置qqconnectconfig.properties
,与application.properties
同一级
app_ID = 你的App ID
app_KEY = 你的App key
redirect_URI = 你的回调域

8 编写controller
//获取用户当前页面的url,方便返回登录之前的页面,
private static String returnUrl = ""
/** * @Description: qq登录的入口 */
@GetMapping("/login")
public ResponseEntity<Void> loginByQQ(HttpServletRequest request, HttpServletResponse response){
returnUrl = request.getParameter("returnUrl");
response.setContentType("text/html,charset=utf-8");
try {
response.sendRedirect(new Oauth().getAuthorizeURL(request));
return ResponseEntity.ok().build();
} catch (IOException | QQConnectException e) {
LOGGER.warn("请求QQ登录失败, {}",e.getMessage());
}
return ResponseEntity.badRequest().build();
}
/** * * 此处的qqlogin必须与你的网站回调域一致 * @Description: 登录获取数据 */
@RequestMapping("/qqlogin")
public String login(HttpServletRequest request,HttpServletResponse response){
User user = new User();
try {
AccessToken accessTokenObj = (new Oauth()).getAccessTokenByRequest(request);
//用来或用户信息,get_user_info参数
String accessToken = null;
String openID = null;
long tokenExpireIn = 0L;
if (accessTokenObj.getAccessToken().equals("")) {
LOGGER.error("没有获取到响应参数");
}else {
accessToken = accessTokenObj.getAccessToken();
tokenExpireIn = accessTokenObj.getExpireIn();
System.out.println(String.valueOf(tokenExpireIn));
// 利用获取到的accessToken 去获取当前用的openid -------- start
OpenID openIDObj = new OpenID(accessToken);
openID = openIDObj.getUserOpenID();
UserInfo userInfo = new UserInfo(accessToken, openID);
UserInfoBean userInfoBean = userInfo.getUserInfo();
/* * 此处获取用户信息后可以在service层重新保存用户部分信息用作登录展示 * 比如写一个UserInfo类用于信息展示,将UserInfo对应的用户信息通过加密的方式保存到 * Cookie中,每次请求都会携带Cookie,然后解密重新设置过期时间再进行加密保存。 * 用户退出就可以将Cookie信息删除,这样就不需要依赖QQ登录本身保存的信息了。 */
if (userInfoBean.getRet()==0){
//获取qq空间头像,暂不知怎么获取qq头像
user.setAvatar(userInfoBean.getAvatar().getAvatarURL50());
//用户openId,唯一标识
user.setOpenId(openID);
//用户qq昵称
user.setNickName(userInfoBean.getNickname());
//用户性别
user.setGender(userInfoBean.getGender());
}else {
LOGGER.warn("很抱歉,我们没能正确获取到您的信息,原因是:{} ", userInfoBean.getMsg());
}
}
} catch (QQConnectException e) {
LOGGER.error("qq连接发生异常 {}",e.getMessage());
}
return "redirect:"+returnUrl;
}
获取用户信息API
get_user_info
通过上面的方法可以获取的用户信息较少,并且获取的头像是QQ空间的头像而不是QQ头像,如果没有QQ空间的话,那么就没有用户头像了。可以通过get_user_info获取用户更多的信息,比如QQ头像!
新建一个用户信息实体类
根据返回的json创建用户对象
package com.cx.pojo;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonProperty;
import jdk.nashorn.internal.ir.annotations.Ignore;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.annotation.Transient;
/** *@JsonIgnoreProperties(ignoreUnknown = true) 忽略部分不能匹配的字段 *@JsonProperty(value = "***"),因为获取的用户信息json不符合java命名规范,所有需要添加字段映射 * @author 苍晓 */
@Data
@AllArgsConstructor
@NoArgsConstructor
@JsonIgnoreProperties(ignoreUnknown = true)
public class ResultInfo {
private int ret;
private String msg;
@JsonProperty(value = "is_lost")
private boolean isLost;
private String nickname;
private String gender;
@JsonProperty(value = "gender_type")
private String genderType;
private String province;
private String city;
private String year;
private String constellation;
private String figureurl;
@JsonProperty(value = "figureurl_1")
private String figureUrl1;
@JsonProperty(value = "figureurl_2")
private String figureUrl12;
@JsonProperty(value = "figureurl_qq_1")
private String figureUrlQq1;
@JsonProperty(value = "figureurl_qq_2")
private String figureUrlQq2;
@JsonProperty(value = "figureurl_qq")
private String figureUrlQq;
@JsonProperty(value = "figureurl_type")
private String figureUrlType;
@JsonProperty(value = "is_yellow_vip")
private String isYellowVip;
private int vip;
@JsonProperty(value = "yellow_vip_level")
private int yellowVipLevel;
private int level;
@JsonProperty(value = "is_yellow_year_vip")
private String isYellowYearVip;
}
RestTemplate配置
package com.blog.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.client.RestTemplate;
import java.util.Arrays;
/** * @author 苍晓 */
@Configuration
public class RestTemplateConfig {
@Bean
public RestTemplate getRestTemplate(){
RestTemplate restTemplate = new RestTemplate();
MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
/* *经过尝试,此处需要加一个MediaType.TEXT_HTML的返回类型,否则一直报错,解析不了返回信息。 */
mappingJackson2HttpMessageConverter.setSupportedMediaTypes(Arrays.asList(MediaType.APPLICATION_JSON,
MediaType.TEXT_HTML));
restTemplate.getMessageConverters().add(mappingJackson2HttpMessageConverter);
return restTemplate;
}
}
测试获取用户信息
//注入rest请求模板
@Autowired
private RestTemplate restTemplate;
private final String preUrl="https://graph.qq.com/user/get_user_info?" +
"access_token=获取的登录用户AccessToken" +
"&oauth_consumer_key=你的AppID" +
"&openid=获取的登录用户的openID";
@Test
void qqInfo() {
String object = this.restTemplate.getForObject(preUrl, String.class);
ObjectMapper objectMapper = new ObjectMapper();
try {
System.out.println("============================");
ResultInfo resultInfo = objectMapper.readValue(object,ResultInfo.class);
System.out.println(resultInfo);
} catch (JsonProcessingException e) {
e.printStackTrace();
}
}
