使用代理中间件与gulp connect

Question

我想使用gulp-connect的所有请求转发给api/到localhost:3000.我在https://github.com/AveVlad/gulp-connect/issues/27上找到了一个例子

并设置我的连接任务,如下所示:

gulp.task('connect', function(){
    connect.server({
        root: './app', 
    middleware: function(connect, o) {
      return [ (function() {
        var url = require('url');
        var proxy = require('proxy-middleware');
        var options = url.parse('http://localhost:3000/api');
        options.route = 'api';
        return proxy(options);
      })()]
    }
    });
});

运行此任务会发出警告,connect deprecated connect(middleware): use app.use(middleware) instead node_modules/gulp-connect/index.js:39:19此任务不会按预期转发请求.

我查看了connect源代码,看看我是否可以解决折旧问题,但它超出了我在js中的水平:

 ConnectApp.prototype.server = function() {
    var app, middleware;
    middleware = this.middleware();
    app = connect.apply(null, middleware);
    server = http.createServer(app);
    app.use(connect.directory(typeof opt.root === "object" ? opt.root[0] : opt.root));
    server.listen(opt.port);
    this.log("Server started http://" + opt.host + ":" + opt.port);
    if (opt.livereload) {
      tiny_lr.Server.prototype.error = function() {};
      lr = tiny_lr();
      lr.listen(opt.livereload.port);
      return this.log("LiveReload started on port " + opt.livereload.port);
    }
  };

我无法弄清楚如何更改我要使用的gulp文件app.use(middleware),app连接模块不会导出该变量.

chimurai在Github上给出的解决方案是使用http-proxy-middleware包来做到这一点.

例如 :

var gulp = require('gulp');
var connect = require('gulp-connect');
var proxy = require('http-proxy-middleware');

gulp.task('connect', function() {
    connect.server({
        root: ['./app'],
        middleware: function(connect, opt) {
            return [
                proxy('/api', {
                    target: 'http://localhost:3000',
                    changeOrigin:true
                })
            ]
        }

    });
});

gulp.task('default', ['connect']);

即使使用github源代码,我也无法使中间件正常工作.我确实得到了相同的结果modrewrite

var modRewrite = require('connect-modrewrite');

gulp.task('connect', function() {
  connect.server({
    root: './app',
    port: 8000,
    middleware: function() {
      return [
        modRewrite([
          '^/api/(.*)$ http://localhost:3000/api/v1/$1 [P]'
        ])
      ];
    }
  });
});

这是一个报告的问题，应该在 NPM 上的下一个 gulp-connect 版本中修复：
