直接通过LB进行访问，测试443和80是否正常，并且验证443端口是否使用了默认的证书

测试IP访问:

```
[root@maxiaoke nginxinc-ingress]# curl -I http://10.4.7.100
HTTP/1.1 404 Not Found
Server: nginx
Date: Wed, 04 May 2022 08:31:59 GMT
Content-Type: text/html
Content-Length: 146
Connection: keep-alive

[root@maxiaoke nginxinc-ingress]# curl -I https://10.4.7.100 -k
HTTP/1.1 404 Not Found
Server: nginx
Date: Wed, 04 May 2022 08:32:16 GMT
Content-Type: text/html
Content-Length: 146
Connection: keep-alive
```

测试域名访问:

```
# 因为是本地vmware搭建的环境，使用 hosts 配置域名解析，解析域名到 LB
[root@maxiaoke nginxinc-ingress]# curl https://test.huanle.com  # 证书验证通过，表明默认证书配置正确
<html>
<head><title>404 Not Found</title></head>
<body>
<center><h1>404 Not Found</h1></center>
<hr><center>nginx</center>
</body>
</html>
```

验证日志格式:

```
# 上述测试中，原客户端IP 10.4.7.1 已经被成功记录到日志中
04/May/2022:16:39:49 +0800|10.4.7.100|10.4.7.1|-|-|||||HEAD|HTTP/1.1|10.4.7.100|/|-|curl/7.68.0|0|404|
04/May/2022:16:39:56 +0800|10.4.7.100|10.4.7.1|-|-|||||GET|HTTP/1.1|test.huanle.com|/|-|curl/7.68.0|146|404|

# 如果带上X-Real-IP和X-Forwarded-For验证，模拟下游其它L7负载均衡器
[root@maxiaoke nginxinc-ingress]# curl -H "X-Real-IP: 192.168.99.251" -H "X-Forwarded-For: 192.168.99.251, 10.4.7.1" https://test.huanle.com
04/May/2022:16:44:33 +0800|10.4.7.100|10.4.7.1|192.168.99.251|192.168.99.251, 10.4.7.1|||||GET|HTTP/1.1|test.huanle.com|/|-|curl/7.68.0|146|404|
