出门在外,没有核酸证明寸步难行,此文将教你如何通过小程序制作一个工具帮你在人生地不熟的情况如何迅速找到核酸检测点,实现核酸点查询、地图导航、拨号等功能。

小程序 创建小程序

访问微信公众平台,点击账号注册。

  1. 选择小程序,并在表单填写所需的各项信息进行注册。


  1. 在开发管理选择开发设置,将AppID及AppSecret复制出来进行存储。

  1. 下载安装微信web开发者工具并创建一个新的项目,填入上图所复制的AppId。


申请腾讯地图用户key

访问腾讯位置服务,申请腾讯地图用户Key,因为在后面我们需要将用户的经纬度解析成地址,所以这个步骤是必不可少的

  1. 点击右上角的登陆,选择注册或绑定现有账号;绑定完毕后选择创建ApiKey


  1. 填写所需的各项表单信息,点击确定将所创建的API Key保存下来。

实现小程序界面

在页面上大致要实现选择省市区功能,然后通过点击查询按钮将核酸点数据进行渲染,实现导航及拨号等细节功能,设计如下。

  1. 在pages文件夹下面创建一个文件夹并新建对应的page文件。

  1. 在index.js中引入utils文件夹下面的引入腾讯地图SDK核心类。

const util = require("../../utils/util.js");
const app = getApp();
// 引入腾讯地图SDK核心类
var QQMapWX = require('../../utils/map/qqmap-wx-jssdk.js');
var qqmapsdk;
  1. 在JS中的onLoad函数中将其进行实例化,复制刚才在腾讯地图所申请的用户key。
 qqmapsdk = new QQMapWX({
      key: '刚刚所申请的key填到这里'
    });
  1. 实现省市区下拉框三级联动,这里需要用到的是picker组件,mode熟悉填写region。
<picker class="picker" mode="region" bindchange="bindPickerChange" value="{{region}}" custom-item="{{customItem}}">
    <view class="address little">
      <text>请选择: </text>
      <text> {{provinceName}} {{cityName}} {{districtName}}</text>
    </view>
  </picker>

  1. 同时实现该组件的响应函数,看是否能够获取到我们所需要的信息,正确响应如下图,然后根据数组下标取到对应的省市区并将其存储到全局的data中。

 bindPickerChange: function (e) {
    let that = this;
    let province = e.detail.value[0];
    let city = e.detail.value[1];
    let district = e.detail.value[2];
   	that .setData({
	     province : province,
	     city : city,
	     district: e.detail.value
   	});
  },
  1. picker组件在加载时候默认是不会选中的,为了优化用户体验,我们需要在加载的时候获取用户的位置并对其进行赋值,首先需要在app.json文件中增加配置。

"permission": {
    "scope.userLocation": {
      "desc": "位置信息效果展示"
    }
  },
	"requiredPrivateInfos": [
		"getLocation"
	]
  1. 回到index.js,在onLoad函数中调用wx.getLocation,这个函数是用于获取用户当前经纬度。

  1. 很显然,经纬度是不能够直接赋值给picker组件的,接下来需要逆解析将其转换为地址,这时候需要用到reverseGeocoder函数了,将上一个函数返回的经纬度作为参数拼接调用,返回的信息中就有我们需要的省市区等详细地址了。

//获取用户当前经纬度
    wx.getLocation({
      type: 'wgs84',
      success (data) {
        // 将用户经纬度转换为地址
        qqmapsdk.reverseGeocoder({//地址解析
          location: {
            longitude: data.longitude,
            latitude: data.latitude,
          },
          success: function (resSuc) {
            let province = resSuc.result.address_component.province;
            let city = resSuc.result.address_component.city;
            let district = resSuc.result.address_component.district;
            that.setData({
              province: province.substr(0, province.length - 1),
              city: city.substr(0, city.length - 1),
              provinceName:province,
              cityName:city,
              districtName:district
            });
          },
          fail: function (errInfo) {
          }
        });
      },
      fail: function (errInfo) {
        console.info(errInfo)
      }
     });

全国省市区数据

后续的接口请求中需要传递不同的城市code,所以现在现在需要封装一个JS,用于传参使用。在utils文件夹中新建一个js文件,将省份及城市数据存放其中,并进行初始化。

var cityData = [{
  "province_id": "1",
  "province": "安徽",
  "citys": [{
    "city_id": "10001",
    "city": "合肥"

API 提交资料认证并申请接口

访问聚合数据,创建/登录账号,点击个人中心,填写对应的资料进行实名认证并申请对应的接口权限。
接口申请地址点此访问

拼接参数调用接口

可以看到调用该接口的参数很简单,只有用户应用key以及city_id,也就是我们上面所封装的省市区js里面的数据。

  1. 复制对应的key并实现从省市区JS中获取用户所选择的城市id。

  1. 因为picker组件所响应的值是某某省、某某市这样的数据,而我们所封装的JS数据中又是没有省跟市这些后缀的,所以在选择的时候需要将省市区进行最后一位的移除,然后再通过findIndex的方式找到对应的下标,通过下标再找到对应的city_id。

  1. 能够正常的获取到城市id后,我们就可以拼接参数调用接口了。

    wx.request({
      url: 'http://apis.juhe.cn/springTravel/hsjg?key=这里填写你的应用key&city_id=' + cityCode,
      method: 'get',
      contentType: "application/x-www-form-urlencoded",
      success: function (res) {
        that.setData({
          hospitalData: res.data.result.data
        });
      }
    });

渲染数据优化细节

查看接口返回并渲染数据,通过上面的步骤我们可以得到如下图,核酸检测点数据已经成功返回了。

  1. 在页面上定义对应的view及wx:for,将核酸检查点名称及电话进行展示。

  1. 在能将数据进行渲染之后,可以优化一些细节,例如导航及拨号等功能。

<image src="../../images/phone.png" class="phoneImg"></image>
 <image src="../../images/map.png" class="mapIcon" data-name="{{item.name}}" data-id="{{item.address}}" bindtap="goMap"></image>
  1. 拨号功能,在拨号图标实现对应的函数,将循环中的电话号码以data-id的方式进行传递。

    wx.makePhoneCall({
      phoneNumber: e.currentTarget.dataset.id,
      success: function () {
        console.log('成功拨打电话')
      }
    })
  1. 导航功能,在地图小图标上面将循环中的address字段以data-id的方式进行传递。因为唤醒地图需要准确的经纬度,所以我们这里还需要将检测点的地址进行转换,最后再使用wx.openLocation通过微信内置地图查看位置及导航。

  goMap(e) {
    let detail = e.currentTarget.dataset.id;
    let name = e.currentTarget.dataset.name;
    //地址转换经纬度
    qqmapsdk.geocoder({
      address: e.currentTarget.dataset.id,
      success: function (res) { //成功后的回调
        wx.openLocation({ //​使用微信内置地图查看位置。
          latitude: parseFloat(res.result.location.lat), //要去的纬度-地址
          longitude: parseFloat(res.result.location.lng), //要去的经度-地址
          name: name,
          address: detail
        })
      }
    });
  },

在路上碰到几个刚来的深漂拎着大包小包问哪里有核酸可以做,给他们指完方向后觉得可以开发一个小工具帮助出门在外的朋友,抗疫不仅仅是精神的对垒也是物质的角力。

到此这篇关于使用微信小程序制作一个核酸检测点查询工具的文章就介绍到这了,更多相关小程序核酸检测点查询工具内容请搜索脚本之家以前的文章或继续浏览下面的相关文章希望大家以后多多支持脚本之家!
