example里有httpserver的demo，可惜是在sta模式下的server，不过也值得验证一下，把验证的过程整理如下：
首先是修改example_connect()函数里的start里的wifi config信息，
wifi_config_t wifi_config = {
.sta = {
.ssid = "matt",
.password = "12345678",
},
};
然后就可以编译了，编译要选择freertos单核运行，然后烧录到开发板中，然后
I (3790) tcpip_adapter: sta ip: 192.168.2.149, mask: 255.255.255.0, gw: 192.168.2.1
I (3790) example_connect: Connected to myssid
I (3790) example_connect: IPv4 address: 192.168.2.149
I (3800) example_connect: IPv6 address: fe80:0000:0000:0000:260a:c4ff:fe85:cdd0
I (3800) example: Starting server on port: '80'
I (3810) example: Registering URI handlers
server创建成功了，怎么验证post功能呢
用tcp工具发
POST /echo HTTP/1.1
Host: 192.168.2.149
Connection: keep-alive
Content-Length: 16
Pragma: no-cache
Cache-Control: no-cache

记住一定要多带一行换行，结果如下：
