1、uniapp要调用腾讯地图，首先要去

腾讯位置服务

上去创建应用绑定


添加key与你小程序appId绑定

2、登录

微信公众平台

，完善小程序信息

3、开通位置权限（这个很重要）(wx.getLocation这个权限不好过审，可能需要多试几次)

4、在uniapp的manifest.json配置清单上配置appId，并选中小程序位置接口，然后打开源码视图，加上你在微信公众平台（上一步）开通的接口权限(这个很重要，不然在微信上没法调用位置)

"mp-weixin" : {
        /* 小程序特有相关 */
        "appid" : "wxxxxxxxx",
        "setting" : {
            "urlCheck" : false,
            "es6" : true,
            "minified" : true,
            "postcss" : false
        },
        "usingComponents" : true,
        "permission" : {
            "scope.userLocation" : {
                "desc" : "你的位置信息将用于小程序位置接口的效果展示"
            }
        },
        "requiredPrivateInfos" : [ "chooseAddress", "choosePoi", "getLocation" ]
    },

5、接下来就可以看着uniapp官方文档调用地理位置接口啦！！！

// 获取定位信息
Mixin_GetLocation() {
	const that = this
	return new Promise((resolve, reject) => {
		this.mixin_JudgeWeixinAuthorizeLocation(() => {
			uni.getLocation({
				type: 'gcj02',
				success(response) {
					that.myLocation = response
					resolve(response)
				},
				fail() {
					reject()
				}
			})
		})
	})
},

/**
 * 判断小程序 和 APP 有没有定位权限
 * @param {function} callback
 * @returns {AxiosPromise}
 */
async mixin_JudgeAuthorizeLocation(callback) {
	const that = this
	// #ifdef MP-WEIXIN
	uni.authorize({
		scope: 'scope.userLocation',
		success(scope) {
			if (scope.errMsg === 'authorize:ok') {
				callback && callback()
			}
		},
		fail(error) {
			console.log('微信小程序获取位置信息失败：', error)
			uni.showModal({
				title: '提示',
				content: '为保证功能正常使用，请开启定位权限',
				confirmText: '去开启',

									that.mixin_JudgeWeixinAuthorizeLocation(
										callback)
								} else {

								}
							}
						})
					}
				}
			})
		}
	})
