介绍
这里是小编成长之路的历程，也是小编的学习之路。希望和各位大佬们一起成长！
以下为小编最喜欢的两句话：
要有最朴素的生活和最遥远的梦想，即使明天天寒地冻，山高水远，路远马亡。
一个人为什么要努力？ 我见过最好的答案就是：因为我喜欢的东西都很贵，我想去的地方都很远，我爱的人超完美。因此，小编想说：共勉！

显示效果
一、注册和风天气的账号（具体过程就不演示了）
和风天气的官网
和风天气插件 | 和风天气插件产品，免费、跨终端。适配你的网站、APP、公众号 ()
二、获取和风天气的key
1、创建项目
控制台===》项目管理===》创建项目 就可以看到以下页面（注意：如果页面不一样的话，可能是更新了）
这个地方注意一下，看你是做案例还是，公司使用，如果是做案例，可以和小编一样选择免费订阅。设置key的地方你可以选择Web API，如果你选择了 Android SDK / iOS SDK，那么生成的密钥只能使用官方的 SDK 进行数据访问，如果是 Web API的话，可以自己编程获取并解析数据。（当然WebAPI解析比较慢一点，可以稍微等一会）
2、获取key
三、在小程序中的使用
如果是小白的话，没有账号，建议注册一个小程序的账号，具体看小编的这篇文章。有账号跳过这个步骤
【微信小程序】注册小程序账号、做一个案例——你好我的小程序_determine ZandR的博客-CSDN博客
第一步：创建包
第二步：示例代码
workweather.wxml

注意： 如果复制上述代码，出现wx.getLocation need to be declared in the requiredPrivateInfos field in app.json的问题，查看两个地方
一、看全局json中是否有以下代码
"requiredPrivateInfos": ["getLocation"]
二、看版本(2.6.0以上版本无法使用)
以上就是小编做的一个小案例，希望各位大佬多多指教！！！
