uniapp开发微信小程序，引入第三方SDK高德地图
一、获取高德Key：官方获取key的方法在这二、创建项目之后下载并安装微信小程序SKD：如果是开发安卓、IOS、APP项目，请找到对应的包下载并解压。下载微信小程序SDK解压后得到 amap-wx.js 文件，在创建的项目中，新建一个名为 libs 目录，将 amap-wx.js 文件拷贝到 libs 的本地目录下，完成安装。这一步在uniapp运行的时候会报错，因为解压后的js文件方法都是wx.

二、创建项目之后下载并安装微信小程序SKD：
如果是开发安卓、IOS、APP项目，请找到对应的包下载并解压。
下载微信小程序SDK
解压后得到 amap-wx.js 文件，在创建的项目中，新建一个名为 libs 目录，将 amap-wx.js 文件拷贝到 libs 的本地目录下，完成安装。
这一步在uniapp运行的时候会报错，因为解压后的js文件方法都是wx.XXX。手动把这些前缀都改成uni.XXX之后可以运行了。
以下是修改之后的文件：

三、SDK导入成功后就可以开始使用了：
1、在需要使用高德地图的vue文件中引入 amap-wx.js 文件。
import amap from '@/common/amap-uni.js';
然后，在.vue中实例化 AMapWX 对象，调用 getPoiAround 方法，获取POI数据。
为保证 marker 以自定义的图标显示，需在给marker一个可以访问到的图片地址（选中状态和未选中状态两张，本地或链接都可以）
以下是完整代码：
<!-- /**
* map 用到的属性
* @param width map宽度
* @param height map高度
* @param latitude 中心纬度
* @param longitude 中心经度
* @param scale 缩放级别，取值范围为5-18
* @param markers 标记点
* @param show-location 显示带有方向的当前定位点
* @param markertap 点击标记点时触发
* */ -->
<view class="content">
<map class="map" id="map" :latitude="latitude" :longitude="longitude" scale="18" show-location="true" :markers="markers"
@markertap="markertap"></map>
</view>
import amap from '@/common/amap-uni.js';
export default {
data() {
return {
amapPlugin: null,
key: '5466',//高德地图key
markers: [],
poisdatas: [],
latitude: 30.208487,
longitude: 120.21202,
}
},
onLoad() {
var that = this;
this.amapPlugin = new amap.AMapWX({
key: this.key
});
this.amapPlugin.getPoiAround({
iconPathSelected: '', //如：../../img/marker_checked.png
iconPath: '', //如：../../img/marker.png
success: function(data) {
//成功回调
that.markers = data.markers;
that.latitude = that.markers[0].latitude;
that.longitude = that.markers[0].longitude;
// that.showMarkerInfo(that.markers,0);
that.poisdatas = data.poisData;
var markers_new = [];
that.markers.forEach(function(item, index) {
markers_new.push({
id: item.id, //marker 序号
width: item.width, //marker 宽度
height: item.height, //marker 高度
iconPath: item.iconPath, //marker 图标路径
latitude: item.latitude, //marker 纬度
longitude: item.longitude, //marker 经度
address: item.address,//marker 地址
name: item.name,//marker 名字
// title:item.name,//标注点名
distance: that.poisdatas[index].distance,//marker 距离中心点之间的距离 mark属性中并没有这个字段，我是因为项目需求需要知道标点跟中心点之间的距离，所以塞了一个字段进去。
//自定义标记点上方的气泡窗口
callout: {
padding: 2, //callout 文本边缘留白
fontSize: 15, //callout 文字大小
bgColor: 'blue', //callout 背景颜色
color: '#6B8E23', //callout 文字颜色
borderRadius: 5, //边框圆角
display: 'BYCLICK', //callout 'BYCLICK':点击显示; 'ALWAYS':常显
content: that.poisdatas[index].name //地理位置名称
}
})
})
that.markers = markers_new;
},
fail: function(info) {
//失败回调
console.log("info", info)
}
})
},
methods: {
jump(path, query) {
this.$Router.push({
path: path,
query: {item:JSON.stringify(query)}
});
},
//点击地图标点时触发
markertap: function(e) {
var id = e.markerId;
var that = this;
that.changeMarkerColor(that.markers,id);
},
changeMarkerColor: function(data, i) {
var that = this;
var markers = [];
for (var j = 0; j < data.length; j++) {
if (j == i) {
data[j].iconPath = ""; //如：../../img/marker_checked.png
} else {
data[j].iconPath = ""; //如：../../img/marker.png
}
markers.push(data[j]);
}
that.marker = markers;
}
}
}
效果图如下：
