在Sails.js中使用快速中间件提供静态文件 [英] Using express middleware in Sails.js to serve static files

问题描述

我在0.11.0航行中使用快速中间件时遇到麻烦.我在http.js文件中尝试了以下内容.

I have trouble using the express middleware on sails 0.11.0. I tried the following in http.js file.

module.exports.http = {

  customMiddleware: function (app) {
    console.log("middleware");
    app.use('/test', express.static('****/****/*****/testProject/api/controllers' + '/public/'));
  }

};

但是它不起作用，我丢失了一些东西.

But it doesn't work, I am missing something.

推荐答案

对于最新的Sails(0.12)，无法直接从config/http.js调用快速样式app.use(...)(或作为策略)，因为自定义中间件功能参数从function (app)更改为function (req, res, next).这可能就是为什么此处的某些答案不适用于Sails 0.12的原因.

With the latest Sails (0.12), calling express-style app.use(...) isn't directly possible from config/http.js (or as a policy) because the custom middleware function parameters changed from function (app) to function (req, res, next). This is probably why some of the answers here don't work with Sails 0.12.

Sails文档和迁移指南中并未明确提及此更改，但请查看 connect-history-api-fallback 为例):

This change isn't clearly mentioned in Sails documentation and migration guides, but looking at Express documentation, we see that app.use(...) can accept a single function (req, res, next) argument... so my guess was to assign the parameter to app.use(...) as a custom middleware in config/http.js like so (using connect-history-api-fallback as an example):

// config/http.js
var history = require('connect-history-api-fallback');

module.exports.http = {
  middleware: {
    order: [
      'startRequestTimer',
      'cookieParser',
      'session',
      'myRequestLogger',
      'bodyParser',
      'handleBodyParserError',
      'compress',
      'methodOverride',
      'poweredBy',
      '$custom',
      'router',
      'connectHistoryApiFallback', // <==
      'www',
      'favicon',
      '404',
      '500'
    ],
  },

  // Do this instead of app.use(history())
  connectHistoryApiFallback: history()
}

voilà，它就像一种魅力！

And voilà, it works like a charm!

TL; DR 自Sails 0.12起，在config/http.js中定义的自定义中间件应为function (req, res, next)类型，而不是function (app)，因此应调用app.use(someMiddleware)，而不是app.use(someMiddleware). c12>直接在sails.config.http.middleware.order中.

TL;DR Since Sails 0.12, custom middlewares defined in config/http.js should be of the type function (req, res, next) and not function (app), so instead of calling app.use(someMiddleware), you should place someMiddleware directly in sails.config.http.middleware.order.
