Sails.js : 删除特定路由的 bodyparser 中间件 [英] Sails.js :remove bodyparser middleware for a specific route

问题描述

有没有办法删除特定路由的中间件

目前所有的中间件都列在 http.js 文件中

<预><代码>['开始请求计时器','cookieParser','会议'，'bodyParser','passportInit','passportSession','我的请求记录器','handleBodyParserError','压缩'，'方法覆盖','供电'，'路由器'，'万维网'，'收藏夹','404','500']

我想删除特定路由的 bodyParser 中间件

sails.js 可以吗??

解决方案

没有以声明方式执行此操作的机制，但是可以，您可以在每个路由的基础上禁用中间件.您可以通过覆盖中间件并检查自定义代码中的路由 URL 来实现，类似于 对 XML 请求使用单独的正文解析器.例如:

//在 config/http.js `middleware` 属性中bodyParser: (function() {//使用默认选项初始化一个船长实例.var skipper = require('skipper')();//创建并返回中间件函数.返回函数(请求，资源，下一个){//如果我们看到想要跳过的路线，就继续.if (req.url === '/dont-parse-me') {返回下一个()；}//否则使用 Skipper 解析正文.返回船长(请求，资源，下一个)；};})()

这是基本的想法.它当然可以做得更优雅一些；例如，如果您想跳过几条路线，您可以将列表保存在一个单独的文件中，然后根据该列表检查当前 URL.

Is there any way to remove middleware for a particular route

currently all the middlewares are listed in http.js file

[
      'startRequestTimer',
      'cookieParser',
      'session',
      'bodyParser',
      'passportInit',
      'passportSession',
      'myRequestLogger',
      'handleBodyParserError',
      'compress',
      'methodOverride',
      'poweredBy',
      'router',
      'www',
      'favicon',
      '404',
      '500'
  ]

I want to remove the bodyParser middleware for a particular route

Is it possible with sails.js??

解决方案

There's no mechanism for doing this declaratively, but yes, you can disable a middleware on a per-route basis. You would do it by overriding the middleware and checking the route URL within your custom code, similar to the solution for using a separate body parser for XML requests. For example:

// In config/http.js `middleware` property

bodyParser: (function() {
  // Initialize a skipper instance with the default options.
  var skipper = require('skipper')();
  // Create and return the middleware function.
  return function(req, res, next) {
    // If we see the route we want skipped, just continue.
    if (req.url === '/dont-parse-me') {
      return next();
    }
    // Otherwise use Skipper to parse the body.
    return skipper(req, res, next);
  };
})()

That's the basic idea. It could certainly be done a bit more elegantly; for example if you had several routes you wanted skipped, you could save the list in a separate file and check the current URL against that list.
