golang实现ios推送

生成pem文件

打开Keychain Access 导出推送证书和私钥

推送证书 cert.p12

私钥 key.p12

导出.pem文件

转换推送证书

openssl pkcs12 -clcerts -nokeys -out cert.pem -in cert.p12

转换私钥

openssl pkcs12 -nocerts -out key.pem -in key.p12  #输入2次密码，后面golang代码中密码部分相同

合并推送证书和私钥

cat cert.pem key.pem > push_ck.pem

测试生成的pem

openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert cert.pem -key key.pem

输出大体如下说明成功

　　

使用golang的推送库 ap

package main

import (
	"log"

	apns "github.com/sideshow/apns2"
	"github.com/sideshow/apns2/certificate"
)

func main() {

	cert, pemErr := certificate.FromPemFile("push_ck.pem", "密码")
	if pemErr != nil {
		log.Println("Cert Error:", pemErr)
	}

	notification := &apns.Notification{}
	notification.DeviceToken = "6970fc6ecdda0fa32f48e920b4657149f394eb2c3f03b7517f11f450a8ba2b41"
	notification.Topic = "com.yghc.property"
	notification.Payload = []byte(`{
		  "aps" : {
			"alert" : "Hello!"
		  }
		}
	`)

	client := apns.NewClient(cert).Production()
        //开发环境
	res, err := client.Development().Push(notification)

	if err != nil {
		log.Println("Error:", err)
		return
	}

	log.Println("APNs ID:", res.ApnsID)
}
