关于html5:在uniapp-H5项目中使用腾讯地图sdk

前言

这里次要针对的是 H5，小程序或 app 都有现成的 sdk 能够应用；
自己是用 uniapp 在做微信公众号的 h5 页面，其中须要把经纬度信息转化成文字描述的地位信息，在腾讯地图开发平台上申请了一个 key，而后下载了一个微信小程序应用的微信小程序 JavaScriptSDK v1.2 然而这个 sdk 是为小程序设计的，所以在 vue 的 h5 中应用会有跨域问题，所以联合 vue-jsonp 对这个 sdk 做了一下批改，能够间接放入 h5 中应用。
此办法不止在 uniapp 中能够应用，在所有 H5 我的项目中都可

阐明

对于 sdk 怎么批改的我就不多说了，想理解的本人看源码，能够下载下面提供的原版比照查看，简略形容一句就是把 sdk 内应用的 wx 对象重写，替换了外面的 request 办法，应用 vue-jsonp 实现跨域。

装置 vue-jsonp

既然是要应用 vue-jsonp，那就要先装置

npm install vue-jsonp

在 main.js 中引入

import {VueJsonp} from 'vue-jsonp'
Vue.use(VueJsonp)

导入代码

上面是我曾经批改好的代码，复制到一个 js 文件放到本人的我的项目内，例如：qqmap-wx-jssdk.js

var vm = ''

/**
 * 这里是重写局部
 */
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)
            })
    }
}

应用

在须要应用的 vue 页面中导入刚刚复制下来的 js 文件

import QQMapWX from '@/common/qqmap-wx-jssdk.js'

结构地图 API 对象

data() {
  return {qqMap: new QQMapWX({key: '你申请的 KEY',vm: this})
  }
}

调用办法，例：

this.qqMap.reverseGeocoder({
  location: {
    latitude: _this.center.lat,
    longitude: _this.center.lng
  },
  success: function(res){console.log(res)
  }
})
