公众号 服务器配置一直请求URL超时，有可能是腾讯的服务器ip被防火墙限制了，将ip加入白名单中

获取微信服务器IP地址
如果公众号基于安全等考虑，需要获知微信服务器的IP地址列表，以便进行相关限制，可以通过该接口获得微信服务器IP地址列表或者IP网段信息。

由于出口IP及入口IP可能存在变动，建议用户每天请求接口1次，以便于及时更新IP列表。为了避免造成单点故障，强烈建议用户不要长期使用旧的IP列表作为api.weixin.qq.com的访问入口。

1. 获取微信API接口 IP地址
使用固定IP访问api.weixin.qq.com时，请开发者注意运营商适配，跨运营商访问可能会存在高峰期丢包问题。
API接口IP即api.weixin.qq.com的解析地址，由开发者调用微信侧的接入IP。

接口调用请求说明

http请求方式: GET https://api.weixin.qq.com/cgi-bin/get_api_domain_ip?access_token=ACCESS_TOKEN


返回说明

正常情况下，微信会返回下述JSON数据包给公众号：
{
	"ip_list": [
		"101.89.47.18",
		"101.91.34.103",
		"101.91.37.13",
		"109.244.129.223",
		"109.244.145.152",
		"109.244.184.250",
		"112.53.42.235",
		"112.60.20.154",

		"116.128.170.42",
		"116.128.184.169",
		"117.144.228.18",
		"117.144.228.62",
		"119.147.6.203",
		"119.147.6.237",

		"43.141.57.197",
		"43.159.233.227",
		"81.69.216.43"
	]
}


错误时微信会返回错误码等信息，JSON数据包示例如下（该示例为AppID无效错误）:
{"errcode":40013,"errmsg":"invalid appid"}


2. 获取微信callback IP地址
请开发者确保防火墙、ddos攻击白名单IP内已添加回调IP，以避免误拦截的情况出现。
callback IP即微信调用开发者服务器所使用的出口IP。

接口调用请求说明
http请求方式: GET https://api.weixin.qq.com/cgi-bin/getcallbackip?access_token=ACCESS_TOKEN
