+## 苹果推送服务证书申请流程
+
+### 1. 申请CRS文件
+    1. 在macos下使用 钥匙串服务
+    2. ![img.png](img.png)
+    3. 填写信息
+       3.1 用户电子邮箱地址: 填写项目的苹果开发者账号的邮箱，很重要!!
+       3.2 常用名称填写和app相关的名称: dimension push apns
+       3.3 CA电子邮箱地址： 留空
+       3.4 请求是：一定要选择存储到磁盘
+    4. 点击“继续”会生成CSR文件，这个文件用用到在第二步里面用来在苹果后台生成 cer文件
+
+### 2. 登陆苹果开发后台
+    2.1: Certificates => 选择添加 => Services => Apple Push Notification service SSL (Sandbox & Production)
+    2.2 选择第一步生成的 CSR 文件，下载 cer文件
+    2.3 选择用 "钥匙串服务" 打开 
+    2.4 在登陆项下，选择密钥，选择对应的文件, 并导出为 .p12 文件格式
+        ![img_1.png](img_1.png)
+    2.5 将p12文件转换成推送服务器需要pem文件
+        openssl pkcs12 -in apns_push_key.p12 -out apns_push_key.pem -nodes -legacy
+        添加-legacy参数可以让 OpenSSL 使用传统加密算法支持模式，这通常能解决兼容性问题。 之前没有使用 -legacy参数导致解析失败!!
+    2.6 将pem文件分离成.cert和.key文件
+        # 提取证书部分到cert.pem
+        openssl x509 -in combined.pem -out cert.pem
+        # 提取私钥部分到private.key
+        openssl rsa -in combined.pem -out private.key
+
+### 3. 推送服务的证书有效为1年，需要及时更新; 统一了开发环境和正式环境的证书
+    3.1 开发环境 api.sandbox.push.apple.com
+    3.2 正式环境 api.push.apple.com
+
+### 4. 研究整个流程花费了1天时间
