描述：
我是使用自己的微信公众号，按照课程步骤通过手机微信端访问连接：
https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx5891af4eefa20f6b&redirect_uri=http://buy.natappvip.cc/sell/wx/auth&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect
能正常获取code，但是按照课程的方式步骤，将code 传入连接：
https://api.weixin.qq.com/sns/oauth2/access_token?appid=wx5891af4eefa20f6b&secret=d3102cc3e29750e9ad07bd123926096f&code=CODE&grant_type=authorization_code
获取access-token时，code能正常获取，但是access_token无法获取到，手机端访问时，本地的控制台打印的日志获取code后，后面也没有打印出其他内容，过来许久出现超时：Connection timed out, 具体信息见下面的图片
首先代码如下：
@RestController
@RequestMapping("/wx")
public class WxController {
private final Logger logger = LoggerFactory.getLogger(WxController.class);
@GetMapping("/auth")
public void auth(@RequestParam("code") String code) {
logger.info("INFO. go to auth function ...");
logger.info("INFO. code={}",code);
String url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=wx5891af4eefa20f6b&secret=d3102cc3e29750e9ad07bd123926096f&code=" + code + "&grant_type=authorization_code";
String url2 = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=wx5891af4eefa20f6b&secret=d3102cc3e29750e9ad07bd123926096f&code=" + code + "&grant_type=authorization_code";
RestTemplate restTemplate = new RestTemplate();
String response = restTemplate.getForObject(url,String.class);
logger.info("INFO. response={}",response);
String response2 = HttpUtil.get(url2);
logger.info("INFO. response2={}",response2);
}
}
通过手机端访问的连接地址也没有错：
因为通过RestTemplate 没有结果，因此我还使用了HttpUtil.get 的方式，结果都是一样
以下是访问截图：
本地控制台输出的日志如下：
此时打印了code，说明appid访问的内容是正确的，个人公众号是OK的
许久后控制台返回超时的情况：
按照公众号说的，获取access_token 需要开放白名单，我也按照文档的做了，还是上面控制的返回结果，下面是我的appid
ip白名单设置：一开始我是设置了我自己的公网ip ，以及 buy.natappvip.cc域名放回的公网ip (118.31.62.7) ，但是还是没有效果，于是我设置了内网地址：10.xx ，192.xx （都是虚拟机的地址）
，内网ip肯定不行的，因为微信没法访问这个地址
buy.natappvip.cc 的公网地址：
buy.natappvip.cc 解析解析虚拟机地址
问题：
1、请问师兄，你当时调试是如何调试的？我按照课程调试不通过。。
2、自己的微信公众号，我设置了ip 白名单，同时确认appid 和 secret 100% 正确，那会是什么原因导致的呢？
3、白名单设置 是设置buy.natappvip.cc 解析的ip 118.31.62.7 ? 还是设置有问题？
通过微信公众号调试工具，确认appid 和 secret 是正确的，截图如下：

同学你好，报出来的错是你的java程序访问
String url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=wx5891af4eefa20f6b&secret=d3102cc3e29750e9ad07bd123926096f&code=" + code + "&grant_type=authorization_code";
超时了，超时的原因是不是电脑网络呢？
你可以打断点，把链接拿出来，用postman请求试试。
