Question

我有一个模型Transactions，我在其中制作了beforeCreate方法：

beforeCreate(values,cb){
   //I want this code to be run in just production enviroment, not in devlopement env
   EmailService.sendMail(values.email,values.data);
   cb();
}

我在这里制作了一个服务EmailService，它将向用户发送邮件。但我确实希望这只能在production enviroment中激活，而不是在开发环境中。

我不想评论这一行，因为我还有许多其他事件只能在生产环境中触发，而不是在测试环境中触发。怎么做？

Answer 1

beforeCreate(values,cb){
   //I want this code to be run in just production enviroment, not in devlopement env
   if (sails.config.environment === 'production') {
     EmailService.sendMail(values.email,values.data);
   }
   cb();
}

Answer 2

在您的应用程序代码中，您可以access the environment through the global config，如下所示：sails.config.environment。

beforeCreate(values,cb){
   // Production
   if (sails.config.environment === "production") {
       EmailService.sendMail(values.email,values.data);
   }
   cb();
}

默认情况下，您的Sails.js应用程序在开发环境中运行。您可以setting the NODE_ENV environment variable（NODE_ENV=production node app.js）或运行sails lift --prod以生产模式运行它。

如果您愿意，您也可以选择在config/local.js中设置环境：

module.exports = {
  /***************************************************************************
   * The runtime "environment" of your Sails app is either typically         *
   * 'development' or 'production'.                                          *
   *                                                                         *
   * In development, your Sails app will go out of its way to help you       *
   * (for instance you will receive more descriptive error and               *
   * debugging output)                                                       *
   *                                                                         *
   * In production, Sails configures itself (and its dependencies) to        *
   * optimize performance. You should always put your app in production mode *
   * before you deploy it to a server.  This helps ensure that your Sails    *
   * app remains stable, performant, and scalable.                           *
   *                                                                         *
   * By default, Sails sets its environment using the `NODE_ENV` environment *
   * variable.  If NODE_ENV is not set, Sails will run in the                *
   * 'development' environment.                                              *
   ***************************************************************************/

   // environment: process.env.NODE_ENV || 'development'
   environment: 'production'
}

仅在sails js（node js framework）的生产环境中运行一个函数
