第三方
WEB開發時常會涉及到第三方登錄的情況，剛剛做了第三方登錄，爲避免忘記做個記錄
環境：windows + jdk1.7 + tomcat1.7
框架：SpringMVC + JPA
準備：
- 申請
- 配置文件
- API
申請成爲開發者
1.新浪：
(1).html及頭部
<html xmlns:wb="https://open.weibo.com/wb> //html中添加此域
<meta property="wb:webmaster" content="e07c114e01c43d01"/> //申請測試站時，獲取(2).配置文件, client_ID和client_SERCRET申請開發站點時獲得
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).官方下載開發包
//將使用的開發包出去test部分內容，其餘打成jar包。 放入maven倉庫(也可直接引入)
weibo_4j2.微信：
(1).申請較爲繁瑣，等待時間長。(個人認證未通過，企業認證可以。 需要提交申請，以及開發者資質申請)
(2).無配置文件
(3).無官方開發包，參照API開發

回調地址
1.新浪
在網站控制檯裏面，設置回調地址在配置文件中：redirect_URI
2.微信
回調地址只需要在申請地址的域名之下，沒有固定寫法
3.QQ
回調地址在配置文件中：redirect_URI
流程
1.新浪
具體說明請查看API
//請求第三方
Oauth oauth = new Oauth();
String url = oauth.authorize("code", ""); //固定傳入code
return "redirect:" + url; //url回調
//回調處理
Oauth oauth = new Oauth();
AccessToken accessToken = oauth.getAccessTokenByCode(code);
String access_token = accessToken.getAccessToken(); //獲取token
String uid = accessToken.getUserUid(); //新浪用戶唯一標識
Users users = new Users(access_token);
User user = users.showUserById(uid); //獲取用戶信息2.微信
//連接接口
public static String baseLogin = "https://open.weixin.qq.com/connect/qrconnect?";
//oauth2獲取access_token接口
public static String baseToken = "https://api.weixin.qq.com/sns/oauth2/access_token?";
//獲取用戶信息接口
public static String baseUser = "https://api.weixin.qq.com/sns/userinfo?";
//appId和appSecret申請時獲得
public static String appId = "x";
public static String appSecret = "x";
//回調地址
public static String redirect_uri = "http://www.hejzj.com/weixin/afterlogin.do";
//固定
public static String response_type = "code";
//權限
public static String scope = "snsapi_login";
//固定
public static String grant_type = "authorization_code";
//調用第三方
String url = baseLogin + "appid=" + appId + "&redirect_uri=" + redirect_uri +
"&response_type=" + response_type + "&scope=" + scope;
//通過httpClient方法獲取httpEntity
HttpGet get = new HttpGet(url);
CloseableHttpResponse httpResponse = null;
httpResponse = httpClient.execute(get);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
HttpEntity entity = httpResponse.getEntity(); //封裝了返回的內容
//轉換成jsonobject
JSONObject jsonObject = JSONObject.fromObject(EntityUtils.toString(entity));
}
//唯一標識
String openId = jsonObject.getString("openid");
//用戶ID
String unionid = jsonObject.getString("unionid");
//獲取用戶信息接口，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();
//此時返回的JsonObject封裝了用戶的信息
JSONObject jsonObject2 = JSONObject.fromObject(EntityUtils.toString(entity2));
}3.QQ
//調用第三方
response.sendRedirect(new Oauth().getAuthorizeURL(request));
//回調
AccessToken accessTokenObj = (new Oauth()).getAccessTokenByRequest(request);
//accessToken
accessToken = accessTokenObj.getAccessToken();
//過期時間
tokenExpireIn = accessTokenObj.getExpireIn();
OpenID openIDObj = new OpenID(accessToken);
//唯一標識
openID = openIDObj.getUserOpenID();
UserInfo qzoneUserInfo = new UserInfo(accessToken, openID);
//用戶信息對象
UserInfoBean userInfoBean = qzoneUserInfo.getUserInfo();其他邏輯屬於業務邏輯
