企业微信接入自有应用实现免登录
公司要将移动端审批流程接入企业微信,员工通过企业微信的自建审批应用就可以在微信端审批单据,要审批单据就先得让企业微信跟用户绑定起来,实现无感自动登录系统内。由于企业的员工已经被手动的从微信拉入企业微信内,这样就不可以通过企业微信的创建人员接口将人员推到微信内。只能在用户第一次登录审批系统的时候去微信获取用户ID(userId)并与审批系统的人员关联起来。绑定好后就可以实现自动登录。
企业微信API:https://work.weixin.qq.com/api/doc#90001/90143/91201
员工点击应用后自动登录步骤如下:
1.拦截用户是否登录
在过滤器或者拦截器内检查用户是否登录,如果没有登录跳转到微信获取用户的身份信息
企业微信API地址:https://work.weixin.qq.com/api/doc#90001/90143/91120
获取企业微信授权信息URL:
https://open.weixin.qq.com/connect/oauth2/authorize?appid=CORPID&redirect_uri=REDIRECT_URI&response_type=code&scope=SCOPE&agentid=AGENTID&state=STATE#wechat_redirec
页面跳转到企业微信后企业微信处理完成后,页面将重新跳转至 redirect_uri参数指定的回调地址并带上参数code=CODE&state=STATE,企业可根据code参数获得员工的userid。code长度最大为512字节。
public static final String OAUTH_CODE_URL = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=%s&redirect_uri=%s&response_type=code&scope=snsapi_base&state=%s#wechat_redirect";Integer serverPort = request.getServerPort();
String port = (null != serverPort && serverPort == 80) ? "" : ":" + serverPort.toString();
String url = "http://" + request.getServerName() // 服务器地址
+ port // 端口号
+ request.getContextPath(); // 项目名称
url = url + "/weixin/auth/weixinLogin/oauthLogin.html";
try{
url = URLEncoder.encode(url, "utf-8");
}catch (UnsupportedEncodingException e){
e.printStackTrace();
}
String weixinUrl = String.format(OAUTH_CODE_URL, "企业ID", url, "state"");
response.sendRedirect(weixinUrl);
2.获取用户信息并登录
微信回调接收到CODE值并用CODE去交换真实的用户信息,如果用户与系统绑定就表示登录成功,登录成功后将用户信息放入SESSION中。这样就可以实现自动登录审批系统了。
/** * 微信回调接口
* @return
*/
public String oauthLogin(){
try{
Map<String, Object> returnMap = WeixinUtil.getUserInfo(code, Constants.APPROVAL);
if (null != returnMap){
//得到微信用户ID
String userid = MapUtils.getString(returnMap, "UserId");
if (!StringUtil.isRealEmpty(userid)){
//用户与微信ID绑定实体
UserWx userWx = userWxManager.findByWXID(userid);
if (userWx != null){
if (StringUtil.isRealEmpty(userWx.getAvatar())){
WxUser wxUser = WeixinUtil.getWxUser(userid, Constants.APPROVAL);
if (null != wxUser && !StringUtil.isRealEmpty(wxUser.getAvatar())){
// +64取小头像 ;+0取大头像
userWx.setAvatar(wxUser.getAvatar());
userWxManager.save(userWx);
}
}
//登录成功,将用户信息放入SESSION等后续操作
.......
return null;
}else{
//显示未绑定的逻辑
return customMethod("unbind");
}
}else{
return customMethod("error");
}
}else{
return customMethod("error");

}catch (Exception e){
