在uniapp H5项目中使用腾讯地图sdk

作者: 最小栗子 | 来源:发表于2020-07-10 15:30 被阅读0次

    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项目中都可以

    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)
                })
        }
    }

          wx.request(Utils.buildWxRequestConfig(options, {
            url: SET_URL_DIRECTION,
            data: requestParam
          }, 'direction'));
        };
    
        Utils.locationProcess(options, locationsuccess);
      }
    };
    
    module.exports = QQMapWX;
    

    使用

    在需要使用的vue页面中导入刚刚复制下来的js文件

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

    构造地图API对象

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

    调用方法,例:

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