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： ? 1 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。 ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 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。 ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 /**      * 微信回调接口      * @return      */     public String oauthLogin(){         try{                           Map returnMap = WeixinUtil.getUserInfo(code, Constants.APPROVAL);
