第一次发文章,最近写了一个集成第三方登录的Demo
- QQ互联/微信开发者平台 通过认证,然后创建应用 获得你的APPID 和AppSecret 配置回调函数
- 微信QQ请求都是https的请求,这里需要一个工具类 HttpClientUtils.java 用来请求QQ或微信的接口,工具类我贴在下面
- 添加 httpclient的依赖 依赖的jar包有：commons-lang-2.6.jar、httpclient-4.3.2.jar、httpcore-4.3.1.jar、commons-io-2.4.jar
- 配置Constants类, APPID 以及 AppSecret 都放到yml文件中
- yml文件中写入你的APPID等信息
- 按开发文档上拼接请求参数,发送请求(代码在下面)

qqAppSecret: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

weCatRedirectUrl: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
开始编写controller层, 我的demo没有前端的页面 所以只是纯后端的请求方式
第一步获取code
@Autowired
private Constants constants;
@RequestMapping("getCode")
public String getCode() throws Exception {
//拼接url
StringBuilder url = new StringBuilder();
url.append("https://graph.qq.com/oauth2.0/authorize?");
url.append("response_type=code");
url.append("&client_id=" + constants.getQqAppId());
//回调地址 ,回调地址要进行Encode转码
String redirect_uri = constants.getQqRedirectUrl();
//转码
url.append("&redirect_uri="+ URLEncodeUtil.getURLEncoderString(redirect_uri));
url.append("&state=ok");
String result = HttpClientUtils.get(url.toString(),"UTF-8");
System.out.println(url.toString());
return url.toString();
}
//上面的请求回返回一个url,然后进入到这个url中 QQ端会把调用你的回调函数,并把code一起传过来
第二步 通过code取到token
/**
* 获取token,该步骤返回的token期限为一个月
* @param code
* @return
* @throws Exception
*/
@RequestMapping("callback.do")
public String getAccessToken(String code) throws Exception {
if (code != null){
System.out.println(code);
}
StringBuilder url = new StringBuilder();
url.append("https://graph.qq.com/oauth2.0/token?");
url.append("grant_type=authorization_code");
url.append("&client_id=" + constants.getQqAppId());
url.append("&client_secret=" + constants.getQqAppSecret());
url.append("&code=" + code);
//回调地址
String redirect_uri = constants.getQqRedirectUrl();
//转码
url.append("&redirect_uri="+ URLEncodeUtil.getURLEncoderString(redirect_uri));
String result = HttpClientUtils.get(url.toString(),"UTF-8");
System.out.println("url:" + url.toString());
//把token保存
String[] items = StringUtils.splitByWholeSeparatorPreserveAllTokens(result, "&");
String accessToken = StringUtils.substringAfterLast(items[0], "=");
Long expiresIn = new Long(StringUtils.substringAfterLast(items[1], "="));
String refreshToken = StringUtils.substringAfterLast(items[2], "=");
if (qqProperties.get("accessToken") != null){
qqProperties.remove("accessToken");
}
if (qqProperties.get("expiresIn") != null){
qqProperties.remove("expiresIn");
}
if (qqProperties.get("refreshToken") != null){
qqProperties.remove("refreshToken");
}
qqProperties.put("accessToken",accessToken);
qqProperties.put("expiresIn",expiresIn);
qqProperties.put("refreshToken",refreshToken);
return result;
}
上面这个controller就是在yml文件中配置的回调函数地址,我这边是把token存到一个map中了
QQ的这个请求返回值是一个字符串 比如
access_token=FE04************************CCE2&expires_in=7776000&refresh_token=88E4************************BE14
这样子的 要取出来的话 需要做一下拆分,但是微信的是返回的json格式的 可以转为model保存
第三步(可选) 上一步获取的token是有期限的,过期就会失效,这里提供了刷新token的方法
/**
* 刷新token
* @return
* @throws Exception
*/
@RequestMapping("refreshToken")
public String refreshToken() throws Exception {
StringBuilder url = new StringBuilder("https://graph.qq.com/oauth2.0/token?");
url.append("grant_type=refresh_token");
url.append("&client_id=" + constants.getQqAppId());
url.append("&client_secret=" + constants.getQqAppSecret());
//获取refreshToken
String refreshToken = (String) qqProperties.get("refreshToken");
url.append("&refresh_token=" + refreshToken); // 该处需要传入上个步骤获取到的refreshToken;
String result = HttpClientUtils.get(url.toString(),"UTF-8");
System.out.println("url:" + url.toString());
//把新获取的token存到map中
String[] items = StringUtils.splitByWholeSeparatorPreserveAllTokens(result, "&");
String accessToken = StringUtils.substringAfterLast(items[0], "=");
Long expiresIn = new Long(StringUtils.substringAfterLast(items[1], "="));
String newRefreshToken = StringUtils.substringAfterLast(items[2], "=");
if (qqProperties.get("accessToken") != null){
qqProperties.remove("accessToken");
}
if (qqProperties.get("expiresIn") != null){
qqProperties.remove("expiresIn");
}
if (qqProperties.get("refreshToken") != null){
qqProperties.remove("refreshToken");
}
qqProperties.put("accessToken",accessToken);
qqProperties.put("expiresIn",expiresIn);
qqProperties.put("refreshToken",newRefreshToken);
return result;
}
第四步,获取用户openId
/**
* 获取用户openId
* @return
* @throws Exception
*/
@RequestMapping("getOpenId")
public String getOpenId() throws Exception {
StringBuilder url = new StringBuilder("https://graph.qq.com/oauth2.0/me?");
//获取保存的用户的token
String accessToken = (String) qqProperties.get("accessToken");
if (!StringUtils.isNotEmpty(accessToken)){
return "未授权";
}
url.append("access_token=" + accessToken);
String result = HttpClientUtils.get(url.toString(),"UTF-8");
String openId = StringUtils.substringBetween(result, "\"openid\":\"", "\"}");
System.out.println(openId);
//把openId存到map中
if (qqProperties.get("openId") != null) {
qqProperties.remove("openId");
}
qqProperties.put("openId",openId);
return result;
}
//这个步骤的正确返回值是callback( {"client_id":"YOUR_APPID","openid":"YOUR_OPENID"} );
也是一个字符串,需要进行拆分保存,这里请求传入的就是上次获取到的token
第五步 获取用户信息
/**
* 根据openId获取用户信息
*/
@RequestMapping("getUserInfo")
public QQUserInfo getUserInfo() throws Exception {
StringBuilder url = new StringBuilder("https://graph.qq.com/user/get_user_info?");
//取token
String accessToken = (String) qqProperties.get("accessToken");
String openId = (String) qqProperties.get("openId");
if (!StringUtils.isNotEmpty(accessToken) || !StringUtils.isNotEmpty(openId)){
return null;
}
url.append("access_token=" + accessToken);
url.append("&oauth_consumer_key=" + constants.getQqAppId());
url.append("&openid=" + openId);
String result = HttpClientUtils.get(url.toString(),"UTF-8");
Object json = JSON.parseObject(result,QQUserInfo.class);
QQUserInfo QQUserInfo = (QQUserInfo)json;
return QQUserInfo;
}
//传入token APPID,openId 就可以获取到用户信息 由于用到的这个工具类 返回的是一个字符串,可以转成object类型,再强转成model
//到此授权就完成了,微信端和QQ不同的地方是微信获取token的时候会把openId一并获取到
回调函数转码工具类
import java.io.UnsupportedEncodingException;
public class URLEncodeUtil {
private final static String ENCODE = "UTF-8";
/**
* URL 解码
*/
public static String getURLDecoderString(String str) {
String result = "";
if (null == str) {
return "";
}
try {
result = java.net.URLDecoder.decode(str, ENCODE);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return result;
}
/**

public static String getURLEncoderString(String str) {

return "";

} catch (UnsupportedEncodingException e) {

return result;
}
}
