内网走nginx代理访问高德webapi2.0
需求：客户的电脑都只能访问内，服务器可以访问外网，客户电脑使用的项目中用到了高德webapi2.0。
10.200.31.45:32100是我们的web服务器。
网上基本上都是对高德webapi1.4的配置方式，而web2.0有一些差别。
1.前端修改高德地图的js应用
如果是index.html引入，
修改之前的应用：
<script type="text/javascript" crossorigin
src="https://webapi.amap.com/maps?v=2.0&key=高德key&plugin=AMap.ToolBar, AMap.ControlBar,AMap.MoveAnimation,AMap.RangingTool,AMap.Geocoder"></script>
<script src="https://webapi.amap.com/loca?v=2.0.0&key=高德key"></script>
修改之后的配置：
<script type="text/javascript" crossorigin src="<%= BASE_URL %>maps?v=2.0&key=高德key&plugin=AMap.ToolBar, AMap.ControlBar,AMap.MoveAnimation,AMap.RangingTool,AMap.Geocoder"></script> <script src="<%= BASE_URL %>loca?v=2.0.0&key=高德key"></script>
如果是js动态加载，代码如下：
/** * 创建高德秘钥 * @param secret */ export function createSecret(secret?:string){ secret=secret||'高德秘钥'; // 拼装脚本字符串 const script = document.createElement('script'); // 高德 Web API 初始化配置 script.innerHTML = ` window._AMapSecurityConfig = { securityJsCode: '${secret}', };`; // 将脚本插入到页面头部 document.head.appendChild(script); } //获取地图地址 const getMapUrl=()=>{ const {map_offline}=Local.getAmapConfig(); let mapUrl='https://webapi.amap.com'; if(map_offline){ mapUrl=''; } if (process.env.NODE_ENV === "development"){ mapUrl='https://webapi.amap.com'; } return mapUrl; } /** * 创建高德script引入脚本 * @param key * @param url */ export function loadAMapScript(url:string,key?:string) { key=key||'高德key'; const mapUrl=getMapUrl(); const src =`${mapUrl}/maps?v=2.0&key=${key}${url}`; console.log('我的src',src); return new Promise((resolve, reject) => { const script = document.createElement('script'); script.src = src; script.async = true; script.onerror = reject; script.onload = resolve; document.head.appendChild(script); }); } /** * 创建高德local script引入脚本 * @param key * @param url */ export function loadAMapLocaScript(key?:string,url?:string=''){ key=key||'高德key'; const mapUrl=getMapUrl(); const src =`${mapUrl}/loca?v=2.0&key=${key}${url}`; return new Promise((resolve, reject) => { const script = document.createElement('script'); script.src = src; script.async = true; script.onerror = reject; script.onload = resolve; document.head.appendChild(script); }); }
然后在main.ts中：
import {DefaultAmapConfig} from "@/xd-common-web/xdConst";
import {loadAMapLocaScript,loadAMapScript,createSecret} from "@/xd-common-web/utils/map/amapLink";
try{
console.log('开始加载地图');
const mapConfig=Local.getAmapConfig()||DefaultAmapConfig;
createSecret(mapConfig.map_secret);
await loadAMapScript("&&plugin=AMap.LineSearch,AMap.StationSearch,AMap.PolylineEditor,AMap.Geocoder,AMap.PlaceSearch,AMap.AutoComplete,Amap.ElasticMarker,AMap.PolygonEditor",mapConfig.map_key);
await loadAMapLocaScript(mapConfig.map_key);
console.log('地图加载成功');
} catch{
console.log('地图加载异常');
}
2.nginx配置如下：
location /restapi/ { proxy_pass https://restapi.amap.com/; } location /restapi/v3/ { proxy_pass https://restapi.amap.com/v3/; } location /webapi/ { proxy_pass https://webapi.amap.com/; } location /webapi/count{ proxy_pass https://webapi.amap.com/count; } location /vdata/ { proxy_pass https://vdata.amap.com/; } location /vdata/style_icon/ { proxy_pass http://vdata.amap.com/style_icon/; } location /vdata/style/{ proxy_pass https://vdata.amap.com/style/; } location /vdata01/ { proxy_pass https://vdata01.amap.com/; } location /vdata02/ { proxy_pass https://vdata02.amap.com/; } location /vdata03/ { proxy_pass https://vdata03.amap.com/; } location /vdata04/ { proxy_pass https://vdata04.amap.com/; } location /wprd01/ { proxy_pass https://wprd01.is.autonavi.com/; } location /wprd02/ { proxy_pass https://wprd02.is.autonavi.com/; } location /wprd03/ { proxy_pass https://wprd03.is.autonavi.com/; } location /wprd04/ { proxy_pass https://wprd04.is.autonavi.com/; } location /webrd01/ { proxy_pass https://webrd01.is.autonavi.com/; } location /webrd02/ { proxy_pass https://webrd02.is.autonavi.com/; } location /webrd03/ { proxy_pass https://webrd03.is.autonavi.com/; } location /webrd04/ { proxy_pass https://webrd04.is.autonavi.com/; } #代理获取js api文件并修改文件内容 location /maps { proxy_set_header Accept-Encoding ""; proxy_pass https://webapi.amap.com/maps; sub_filter_types *; sub_filter_once off; sub_filter 'http://webapi.amap.com' 'http://10.200.31.45:32100/webapi'; sub_filter 'https://webapi.amap.com' 'http://10.200.31.45:32100/webapi'; sub_filter 'http://restapi.amap.com' 'http://10.200.31.45:32100/restapi'; sub_filter 'https://restapi.amap.com' 'http://10.200.31.45:32100/restapi'; sub_filter 'http://vdata.amap.com' 'http://10.200.31.45:32100/vdata'; sub_filter 'https://vdata.amap.com' 'http://10.200.31.45:32100/vdata'; sub_filter 'webapi.amap.com' '10.200.31.45:32100/webapi'; sub_filter 'vdata.amap.com' '10.200.31.45:32100/vdata'; sub_filter 'restapi.amap.com' '10.200.31.45:32100/restapi'; sub_filter 'vdata0{1,2,3,4}.amap.com' '10.200.31.45:32100/vdata0{1,2,3,4}'; sub_filter '{vdata,vdata01,vdata02,vdata03,vdata04}.amap.com' '10.200.31.45:32100/{vdata,vdata01,vdata02,vdata03,vdata04}'; sub_filter 'webapi.amap.com/count' '10.200.31.45:32100/webapi/count'; sub_filter 'webapi.amap.com/theme' '10.200.31.45:32100/webapi/theme'; sub_filter 'restapi.amap.com/v3' '10.200.31.45:32100/restapi/v3'; sub_filter 'webapi.amap.com/style' '10.200.31.45:32100/webapi/style'; sub_filter 'wprd0{1,2,3,4}.is.autonavi.com' '10.200.31.45:32100/wprd0{1,2,3,4}'; sub_filter 'webrd0{1,2,3,4}.is.autonavi.com' '10.200.31.45:32100/wprd0{1,2,3,4}'; sub_filter 'https' 'http'; } location /loca { proxy_set_header Accept-Encoding ""; proxy_pass https://webapi.amap.com/loca; sub_filter_types *; sub_filter_once off; sub_filter 'webapi.amap.com/count' '10.200.31.45:32100/webapi/count'; sub_filter 'https' 'http'; }
至此，就配置好了。注意：实际项目中nginx配置文件中的10.200.31.45:32100可使用变量代替。
实现思路：通过特定的前缀maps和loca把高德webapi的引用进行转发，转发之后，高德加载地图时，自动会调用一些接口，使用sub_filter 对返回的内容进行替换，替换为服务器的地址+特定前缀，再根据前缀二次转发即可。
