构造网页授权url

首先构造网页授权url，然后构成超链接让用户点击

WxCpService wxCpService = ...;
wxCpService.getOauth2Service().buildAuthorizationUrl(null);

获得用户基本信息

当用户同意授权后，会回调所设置的url并把authorization code传过来，然后用这个code获得user id.

String[] res =  wxCpService.getOauth2Service().getUserInfo(code);
String userId = res[0];
String deviceId = res[1];
String encType = request.getParameter("encrypt_type");
String nonce = request.getParameter("nonce");
String timestamp = request.getParameter("timestamp");
String msgSignature = request.getParameter("msg_signature");
String signature = request.getParameter("signature");
String openid = request.getParameter("openid");
log.info("接收微信请求：[openid=[{}], [openid=[{}],[signature=[{}], encType=[{}], msgSignature=[{}],"
  + " timestamp=[{}], nonce=[{}], requestBody=[{}] ",
  appid, openid, signature, encType, msgSignature, timestamp, nonce, requestBody);

if (!this.wxMpService.switchover(appid)) {
  throw new IllegalArgumentException(String.format("未找到对应appid=[%s]的配置，请核实！", appid));
}

if (!wxMpService.checkSignature(timestamp, nonce, signature)) {
  throw new IllegalArgumentException("非法请求，可能属于伪造的请求！");
}
return ResponseEntity.ok("");
