W5500 and stm32 connection circuit_[STM32+W5500] 22, W5500 failed to connect to an external server,

Project description

1，W5500连接外部服务器ONENET失败，主要是IP地址错误，推荐使用IP 183.230.40.34 ，端口80

2，在ONENET官网上面，可以看到服务器的IP地址为      ONENET

HTTP服务器地址域名为:jjfarfapi.heclouds.com 端口号为80，

jjfarfapi.heclouds.com >> 183.230.40.34

3， 与平台HTTP服务器建立HTTP连接，服务器URL:api.heclouds.com 端口号:80

api.heclouds.com >> 183.230.40.33

4，实际使用情况是这样的，

当ONENET的服务器IP地址为183.230.40.33 时候，HOST的URL为：strcat(pkt, "Host:jjfarfapi.heclouds.comrn");
