一个例子
generator.js
:
exports.read = function *(){
var a = yield read('co.github.js');
var b = yield read('co.recevier.js');
var c = yield read('co.yield.js');
console.log([a,b,c]);
}
function read(file) {
return function(fn){
fs.readFile(file, 'utf8', fn);
}
}
co.js
:
var co = require('co');
var fs = require('fs');
var gen = require('./generator')
/*function read(file) {
return function(fn){
fs.readFile(file, 'utf8', fn);
}
}*/
co(gen.read)()
似乎exports
不支持生成器功能。
require, module, __filename, __dirname) { module.exports.read = function *(){

我为什么要这样做?我只想将我的数据与控制器分开。有什么办法解决吗?
