uniapp H5项目中使用腾讯地图sdk
2021-06-28 本文已影响0人
_草木一秋
前言
这里主要针对的是H5，小程序或app都有现成的sdk可以使用；
本人是用uniapp在做微信公众号的h5页面，其中需要把经纬度信息转化成文字描述的位置信息，在腾讯地图开发平台上申请了一个key，然后下载了一个微信小程序使用的微信小程序JavaScriptSDK v1.2但是这个sdk是为小程序设计的，所以在vue的h5中使用会有跨域问题，所以结合vue-jsonp对这个sdk做了一下修改，可以直接放入h5中使用。
此方法不止在uniapp中可以使用，在所有H5项目中都可
说明
关于sdk怎么修改的我就不多说了，想了解的自己看源码，可以下载上面提供的原版对比查看，简单描述一句就是把sdk内使用的wx对象重写，替换了里面的request方法，使用vue-jsonp完成跨域。
安装vue-jsonp
既然是要使用vue-jsonp，那就要先安装
npm install vue-jsonp
在main.js中引入
import { VueJsonp } from 'vue-jsonp'
Vue.use(VueJsonp)
导入代码
下面是我已经修改好的代码，复制到一个js文件放到自己的项目内，例如：qqmap-wx-jssdk.js
var vm = ''
/**
* 这里是重写部分
*/
var wx = {
request(obj){
obj.data.output = 'jsonp'
vm.$jsonp(obj.url,obj.data)
.then(json => {
if(json.status == 0){
obj.success(json)
}else {
obj.fail(json)
}
})
.catch(err => {
obj.fail(err)
})
}
}
