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。
