+# 安全密钥 v2.3.0
+
+<p color="#f00">
+注意：此次升级不会影响之前已获得 key 的使用；
+升级之后的新增的key必须要配备安全密钥一起使用，
+具体用法请您参看下文《JSAPI key和安全密钥设置和使用》（本次key升级新增安全密钥，是为了提升广大用户的对自己的key安全有效管理，降低明文传输被窃取的风险 。）
+</p>
+
+
+## 方法一 通过代理服务器使用安全密钥 [推荐]
+
+### 1. key搭配代理服务器并携带安全密钥转发（安全）
+
+```JavaScript
+new AMapJS.AMapLoader({
+  version: '2.0',
+  key: '您申请的高德Key值',
+  security: {
+    serviceHost: '您的代理服务器域名或地址/_AMapService'
+  }
+});
+```
+
+### 2. 代理服务器的设置
+
+以 Nginx 反向代理为例，参考以下三个location配置，进行反向代理设置，分别对应自定义地图、海外地图、Web服务，其中自定义地图和海外地图如果没有使用到相关功能也可以不设置。需要将以下配置中的“您的安全密钥”六个字替换为您刚刚获取的jscode安全密钥。
+
+```yml
+server {
+    listen       80;             #nginx端口设置，可按实际端口修改
+    server_name  127.0.0.1;      #nginx server_name 对应进行配置，可按实际添加或修改
+    
+    # 自定义地图服务代理
+    location /_AMapService/v4/map/styles {
+        set $args "$args&jscode=您的安全密钥";
+        proxy_pass https://webapi.amap.com/v4/map/styles;
+    }
+    # 海外地图服务代理
+    location /_AMapService/v3/vectormap {
+        set $args "$args&jscode=您的安全密钥";
+        proxy_pass https://fmap01.amap.com/v3/vectormap;
+    }
+    # Web服务API 代理
+    location /_AMapService/ {
+        set $args "$args&jscode=您的安全密钥";
+        proxy_pass https://restapi.amap.com/;
+    }
+}
+```
+
+保存相关配置之后需要通过命令nginx -s reload  命令重新加载 nginx 配置文件
+
+## 方法二 直接使用安全密钥
+此方式仅建议开发环境使用
+
+```JavaScript
+new AMapJS.AMapLoader({
+  version: '2.0',
+  key: '您申请的高德Key值',
+  security: {
+    securityJsCode: '您申请的安全密钥'
+  }
+});
+```
+
+## 传统方式
+
+具体细节参见[高德开发平台](https://lbs.amap.com/api/javascript-api/guide/abc/prepare).
+
+```html
+<script type="text/javascript">
+window._AMapSecurityConfig = {
+  serviceHost:'您的代理服务器域名或地址/_AMapService',  
+  // 例如 ：serviceHost:'http://1.1.1.1:80/_AMapService',
+}
+</script>
+<script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=您申请的key值"></script> 
+```
