/** * 获取用户信息 * @param openId 用户唯一标识 * @return * @throws Exception */ public WXUserInfo getUserInfo(String openId) throws Exception { String userInfoStr = HttpRequest.sendGet("https://api.weixin.qq.com/cgi-bin/user/info", "access_token=" + getAccessToken() + "&openid=" + openId + "&lang=zh_CN"); Gson gson = new Gson(); WXUserInfo wxUserInfo = gson.fromJson(userInfoStr, WXUserInfo.class); System.out.println(userInfoStr); return wxUserInfo; }
