tips：接口需要注册自己的账号, 测试后开通接口权限
接口官方文档 http://tianqiapi.com/index/doc?version=v11

该接口2小时更新一次，返回最近40日天气, 包含每日日期、农历日期、星期几、天气情况、白天天气、夜间天气、高温低温、日出日落时间、空气质量等，可按地名、城市编号、LBS、IP查询。

使用天气api接口获取济南地区或整个山东地区的所有城市气象灾害预警信息

打开application目录下的 common.php, 在顶部增加error_reporting(1^2);

有上一页的情况下正常返回上一页, 通过分享进入的, 返回到小程序首页
参考代码：

preview(event) {
var _this = this;
console.log(event.currentTarget.dataset.src)
let currentUrl = event.currentTarget.dataset.src
wx.previewImage({
current: currentUrl, // 当前显示图片的http链接
urls: _this.data.imglist// 需要预览的图片http链接列表, 如只预览当前图片, 赋值 [currentUrl]
})
},

callPhone() {
wx.makePhoneCall({
phoneNumber: '400-0088-888' //仅为示例，并非真实的电话号码
})
},

copyweixin(){
wx.setClipboardData({
data: '15562679693',
success (res) {
wx.getClipboardData({
success (res) {
console.log(res.data) // data
}
})
}
})
}

修改/usr/local/redis/etc/redis.conf

maxmemory 1GB
maxmemory-policy volatile-random

Redis的maxmemory_policy内存淘汰策略：

1、volatile-lru：只对设置了过期时间的key进行LRU（默认值）
2、allkeys-lru ： 删除lru算法的key
3、volatile-random：随机删除即将过期key
4、allkeys-random：随机删除
5、volatile-ttl ： 删除即将过期的
6、noeviction ： 永不过期，返回错误
