Lua

步骤一：准备环境

安装Funcraft，最简单的方式就是直接下载可执行的二进制文件。

1. 安装Funcraft到本机。详情请参见安装Funcraft。
2. 执行fun --version检查安装是否成功。
3. 执行fun config配置Funcraft。然后按照提示依次配置Account ID、Access Key ID、Access Key Secret、Default region name。

   fun config
   Aliyun Account ID 1234xxx
   Aliyun Access Key ID xxxx
   Aliyun Access Key Secret xxxx
   Default region name cn-xxxx
   The timeout in seconds for each SDK client invoking 300
   The maximum number of retries for each SDK client 5
   Allow to anonynously report usage statistics to improve the tool over time? (Y/n)

步骤二：部署和调用函数

1. 执行以下命令克隆示例工程到本地。

   git clone https://github.com/awesome-fc/fc-custom-demo          

   说明 如果您没有安装Git，可以直接在浏览器地址栏输入https://github.com/awesome-fc/fc-custom-demo，然后单击下载按钮直接下载。
2. （可选）将lua-demo目录中的代码示例进行修改实现您的业务逻辑。
3. 执行以下命令进入克隆的示例项目中。

   cd fc-custom-demo
   cd lua-demo

4. 执行以下命令将项目部署至函数计算。

   fun deploy -y

   返回结果如下。

   ...
   Waiting for service lua-demo to be deployed...
           Waiting for function fc-lua to be deployed...
                   Waiting for packaging function fc-lua code...
                   The function fc-lua has been packaged. A total of 7 files were compressed and the final size was 10.62 MB
           function fc-lua deploy success
   service lua-demo deploy success

5. 执行以下命令调用部署的函数。

   fun invoke -e "Hello World"

   返回结果如下。

   ...
