Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

前言

Tips:

1、uniapp关于获取位置文档 文档中表述:在小程序平台,api默认不返回详细地址中文描述(即逆地理编码)。推荐使用高德地图小程序sdk,在app和微信上都可以获得中文地址。

2、位置接口增加频率限制

当前小程序频繁调用wx.getLocation接口会导致用户手机电量消耗较快,请开发者改为使用持续定位接口wx.onLocationChange,该接口会固定频率回调,使用效果与跟频繁调用getLocation一致。 从基础库2.17.0版本起(预计发布时间2021.4.9),将对getLocation接口增加频率限制,包括:

  • 1、在开发版或体验版中,30秒内调用getLocation,仅第一次有效,剩余返回fail。
  • 2、正式版中,为保证小程序正常运行同时不过度消耗用户电量,一定时间内(根据设备情况判断)调用getLocation,仅第一次会返回实时定位信息,剩余返回与第一次定位相同的信息。 个人补充: 1、sdk方法的调用时间间隔10s内会报错,超过则不报错。

Tips:

1、地图POI:某个地理位置周边的信息


二、插件使用步骤

1、导入方式

  "dependencies": {
    "cm-amap": "^1.0.3"
  }
  • 3.2、打开项目中的终端,输入:
npm install
  • 3.3、下载成功后在【node_modules】中显示

2、插件引用

Tips: 推荐npm引用

2.1、uni_modules引用

import {
		zmRegeo,
		zmWeather,
	} from '@/uni_modules/cm-amap/index.js'
	
import {
		zmCalculateDistance,
	} from '@/uni_modules/cm-amap/libs/common.js'

2.2、npm引用

import {
		zmRegeo,
		zmWeather,
	} from 'cm-amap/index.js'
	
import {
		zmCalculateDistance,
	} from 'cm-amap/libs/common.js'
  • 插件ZIP下载导入项目,使用的时候,除了注册引用的路径不一致,其他全部一致

3、方法使用

		methods: {
			zmRegeo,
			zmWeather,
			zmCalculateDistance,
			async regeoClick() {
				this.geoData = (await this.zmRegeo())[0];
				console.log("this.geoData: " + JSON.stringify(this.geoData));
			},

			async weatherClick() {
				let _da = await this.zmWeather();
				for (const key in _da) {
					console.log(key);
					if (key !== 'liveData') {
						this.weather.data.push({
							name: 'div',
							children: [{
								type: 'text',
								text: _da[key].text + ':' + _da[key].data
							}]
						});
					}
				}
				this.weather.hasData = true
				console.log("_da: " + JSON.stringify(_da));
			},
			
			// 距离计算
			calDis () {
				var __dis = this.zmCalculateDistance(24.445676, 118.082745, 24.445676, 118.082545)
				console.log("__dis:", __dis+"米");
			}
			
		},


三、高德地图小程序sdk使用步骤

1、在高德开放平台,注册账号并申请 key 等相关信息;

2、下载微信小程序SDK

3、导入SDK并使用

// 引入SDK
import amap from '../../common/amap-wx.js';  

export default {  
    data() {  
        return {  
            amapPlugin: null,  //sdk对象 
            key: '高德key',  
            addressName: '',  
            weather: {  
                hasData: false,  
                data: []  
            }  
        }  
    },  
    onLoad() {
		// 初始化实例对象
        this.amapPlugin = new amap.AMapWX({  
            key: this.key  
        });  
    },  
    methods: {  
		// 获取地理位置信息
        getRegeo() {  
            uni.showLoading({  
                title: '获取信息中'  
            });  
            this.amapPlugin.getRegeo({  
                success: (data) => {  
                    console.log(data)  
                    this.addressName = data[0].name;  
                    uni.hideLoading();  
                }  
            });  
        },
		getWeather() {
				uni.showLoading({
					title: '获取信息中'
				});
				this.amapPlugin.getWeather({
					success: (data) => {
						console.log(data);
						for (const key in data) {
							console.log(key);
							if (key !== 'liveData') {
								this.weather.data.push({
									name: 'div',
									children: [{
										type: 'text',
										text: data[key].text + ':' + data[key].data
									}]
								});
							}
						}
						uni.hideLoading();
						this.weather.hasData = true;
					}
				});
			}
    }  
}
