第三方
WEB开发时常会涉及到第三方登录的情况，刚刚做了第三方登录，为避免忘记做个记录
环境：windows + jdk1.7 + tomcat1.7
框架：SpringMVC + JPA
准备：
- 申请
- 配置文件
- API
申请成为开发者
1.新浪：
(1).html及头部
<html xmlns:wb="https://open.weibo.com/wb> //html中添加此域
<meta property="wb:webmaster" content="e07c114e01c43d01"/> //申请测试站时，获取(2).配置文件, client_ID和client_SERCRET申请开发站点时获得
client_ID = x
client_SERCRET = x
redirect_URI = http://www.hejzj.com/sina/loginSinaAction.do
baseURL=https://api.weibo.com/2/
accessTokenURL=https://api.weibo.com/oauth2/access_token
authorizeURL=https://api.weibo.com/oauth2/authorize
rmURL=https://rm.api.weibo.com/2/(3).官方下载开发包
//将使用的开发包出去test部分内容，其余打成jar包。 放入maven仓库(也可直接引入)

(1).申请较为繁琐，等待时间长。(个人认证未通过，企业认证可以。 需要提交申请，以及开发者资质申请)
(2).无配置文件
(3).无官方开发包，参照API开发

回调地址
1.新浪
在网站控制台里面，设置回调地址在配置文件中：redirect_URI
2.微信
回调地址只需要在申请地址的域名之下，没有固定写法
3.QQ
回调地址在配置文件中：redirect_URI
流程
1.新浪
具体说明请查看API
//请求第三方
Oauth oauth = new Oauth();
String url = oauth.authorize("code", ""); //固定传入code
return "redirect:" + url; //url回调
//回调处理
Oauth oauth = new Oauth();
AccessToken accessToken = oauth.getAccessTokenByCode(code);
String access_token = accessToken.getAccessToken(); //获取token
String uid = accessToken.getUserUid(); //新浪用户唯一标识
Users users = new Users(access_token);
User user = users.showUserById(uid); //获取用户信息2.微信
//连接接口
public static String baseLogin = "https://open.weixin.qq.com/connect/qrconnect?";
//oauth2获取access_token接口
public static String baseToken = "https://api.weixin.qq.com/sns/oauth2/access_token?";
//获取用户信息接口
public static String baseUser = "https://api.weixin.qq.com/sns/userinfo?";
//appId和appSecret申请时获得
public static String appId = "x";
public static String appSecret = "x";
//回调地址
public static String redirect_uri = "http://www.hejzj.com/weixin/afterlogin.do";
//固定
public static String response_type = "code";
//权限
public static String scope = "snsapi_login";
//固定
public static String grant_type = "authorization_code";
//调用第三方
String url = baseLogin + "appid=" + appId + "&redirect_uri=" + redirect_uri +
"&response_type=" + response_type + "&scope=" + scope;
//通过httpClient方法获取httpEntity
HttpGet get = new HttpGet(url);
CloseableHttpResponse httpResponse = null;
httpResponse = httpClient.execute(get);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
HttpEntity entity = httpResponse.getEntity(); //封装了返回的内容
//转换成jsonobject
JSONObject jsonObject = JSONObject.fromObject(EntityUtils.toString(entity));
}
//唯一标识
String openId = jsonObject.getString("openid");
//用户ID
String unionid = jsonObject.getString("unionid");
//获取用户信息接口，再次使用httpClient
String userUrl = baseUser + "access_token=" + accessToken + "&openid=" + openId + "&lang=zh_CN";
get.setURI(new URI(userUrl));
httpResponse = httpClient.execute(get);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
HttpEntity entity2 = httpResponse.getEntity();
//此时返回的JsonObject封装了用户的信息
JSONObject jsonObject2 = JSONObject.fromObject(EntityUtils.toString(entity2));
}3.QQ
//调用第三方
response.sendRedirect(new Oauth().getAuthorizeURL(request));
//回调
AccessToken accessTokenObj = (new Oauth()).getAccessTokenByRequest(request);
//accessToken
accessToken = accessTokenObj.getAccessToken();
//过期时间
tokenExpireIn = accessTokenObj.getExpireIn();
OpenID openIDObj = new OpenID(accessToken);
//唯一标识
openID = openIDObj.getUserOpenID();
UserInfo qzoneUserInfo = new UserInfo(accessToken, openID);
//用户信息对象
UserInfoBean userInfoBean = qzoneUserInfo.getUserInfo();其他逻辑属于业务逻辑
