最近的一些疫情信息很让人揪心，为了方便大家掌握疫情信息，在空闲之余做了一个关于 nCoV 的疫情监控小助手。主要的功能是通过企业微信的 WebHook 来推送疫情信息。这里将使用 Serverless 的整体代码思路和架构方式分享给大家。
\n我们想要实现的大致的效果是这样的：
\n
首先，我们需要解决的是数据来源问题，这里我们可以使用python爬虫来做这件事情，但是由于个人比较懒所以直接用的 2019-nCoV-Crawler ，这个项目已经集成了现有的API，所以我们直接调用即可。当然有能力的同学也可以自己部署Python，我这边是自己部署的，但是这不是本次的重点，就不再赘述。
\n现在，我们有了数据，但是数据怎么打到服务器呢？又该如何触发？当然使用CVM也是可以的，但是似乎太笨拙，并且消耗量很大，需要自己搭好所有环境。所以，这里我们选用Serverless方式来部署。
\n我们来看看整体业务的代码部分吧，毕竟这里是整个机器人的核心。我们来看代码（请求三次接口）：
\n<?php\nfunction main_handler($event, $context) {\n// 广东省情况\n$curlsz = curl_init();\ncurl_setopt_array($curlsz, array(\n CURLOPT_URL =>

\n那么我们接下了重点看下如何将我们的业务代码上传到云端呢？\n这里的云端我用的是腾讯云Serverless服务 SCF云函数 。整个部署，使用过程都是免费的，对于开发者来讲小项目使用的话免费额度是完全够用的。无需担心额外付费。
\nServerless部署，选用的是比较流行的 Serverless Framework，使用和部署也是完全免费的，那么下面我就来介绍下具体的部署过程吧。
\n首先，第一步，我们来安装一个Serverless framework的开发框架：
\n$ npm install -g serverless然后，我们创建一个函数目录：
\n$ mkdir nCov-function\n$ cd nCov-function相关函数目录的内容如下：
\n|- code\n |- index.php // 这里就是上面的业务代码存放位置\n|- serverless.yml //serverless 配置文件接下来，是我们的重头戏，配置函数yml文件：
\n# serverless.yml\nmyFunction:\n component: \"@serverless/tencent-scf\" //引用tencent-scf component\n inputs:\n name: nCoVFunction //函数名称\n enableRoleAuth: true\n codeUri: ./code //代码本地存放位置\n handler: index.main_handler\n runtime: Php5\n region: ap-shanghai //函数运行地域\n description: My Serverless nCoV Function.\n memorySize: 128 //运行内存\n timeout: 20 //超时时间\n exclude:\n - .gitignore\n - .git/**\n - node_modules/**\n - .serverless\n - .env\n include:\n - ./nCoVFunction.zip\n environment:\n variables:\n TEST: vale\n vpcConfig:\n subnetId: ''\n vpcId: ''\n events:\n - timer: // 定时触发器\n name: timer\n parameters:\n cronExpression: '0 0 10,21 * * * *' //明天早上10点，晚上21点\n enable: true万事具备，我们就可以直接部署 SLS 了。
\n通过sls命令（serverless的缩写）进行部署，并可以添加–debug参数查看部署过程中的信息：
\ntaborchen$ sls --debug\n\n DEBUG ─ Resolving the template's static variables.\n DEBUG ─ Collecting components from the template.\n DEBUG ─ Downloading any NPM components found in the template.\n DEBUG ─ Analyzing the template's components dependencies.\n DEBUG ─ Creating the template's components graph.\n DEBUG ─ Syncing template state.\n DEBUG ─ Executing the template's components graph.\n DEBUG ─ Compressing function nCoVFunction file to /Users/taborchen/Desktop/工作/yiqing/.ser\nverless/nCoVFunction.zip.\n DEBUG ─ Compressed function nCoVFunction file successful\n DEBUG ─ Uploading service package to cos[sls-cloudfunction-ap-shanghai-code]. sls-cloudfunc\ntion-default-nCoVFunction-1580960644.zip\n DEBUG ─ Uploaded package successful /Users/taborchen/Desktop/工作/yiqing/.serverless/nCoVFu\nnction.zip\n DEBUG ─ Creating function nCoVFunction\n DEBUG ─ Created function nCoVFunction successful\n DEBUG ─ Setting tags for function nCoVFunction\n DEBUG ─ Creating trigger for function nCoVFunction\n DEBUG ─ Created timer trigger timer for function nCoVFunction success.\n DEBUG ─ Deployed function nCoVFunction successful运行结果如下：

这样，我们就完成了一个 nCoV 的在线触发函数机器人～是不是很简单呢？快来开始动手吧～
