Я пытаюсь загрузить данные из memcached (РЕДАКТИРОВАТЬ: с помощью пакета nodejs memcached), но я продолжаю получать что-то вроде:

{ available_ads: <Buffer 5b 7b 22 69 64 22 3a 37 31 34 31 35 2c 22 74 69 74 6c
65 22 3a 22 44 6f 6c 6c 61 72 53 68 61 76 65 43 6c 75 62 2e 63 6f 6d 22 2c 22 73
75 62 74 69 74 6c ...>, cas: '2' }

Я не знаю много о memcached, так что, возможно, это из-за недопустимого символа. Вот вывод из telnet:

Может кто-нибудь сказать мне, почему библиотека nodejs будет выводить тег буфера?

РЕДАКТИРОВАТЬ: вот мой код

var Memcached = require('memcached');
var memcached = new Memcached('localhost:11211');

memcached.gets('available_ads', function(err, data){
  if(err){ console.log(err); }
  console.log(data);
  res.json({'click_url' : data});
});

попробуйте использовать:

data.toString();

и тогда вам, вероятно, потребуется использовать JSON.parse:

JSON.parse(data.toString());

Когда вы сохраняете / устанавливаете, вам нужно хранить как String.

Пример:

mc.set('keyName', JSON.stringify(thisObj), {expires:0}, function(err, val){
    if (err) {
        callback(err);
    } else {
    callback(null, thisObj);
    }
});

Затем, когда вы прочитаете его обратно, просто прочитайте его как обычный json.

Пример:

mc.get('keyName', async function(err, data){
    callback(null, JSON.parse(data));
}
