（这句话翻译过来我有些不理解，我就不再翻译，res.end用于结束响应） 快速结束响应而无需任何数据，如果你需要对数据进行响应，取而代之的是使用诸如res.send和res.json res.send(...]) 发送http响应 body参数可以是一个buffer对象，字符串，对象，数组.举个栗子： res.send(new Buffer('whoop')) res.send({some:'json'}...) res.send('some html') res.status(404).send('sorry,er can not find that!')...res.status(500).send({error:'something brew up'}) 当参数是一个buffer对象时，该方法设置Content-Type响应头字段为application/...当参数为字符串时，这个方法设置'Content-Type'为'text/html' res.send('some html') 当参数为数组或者对象时，Express用JSON表示响应 res.send
