我在node.js中有这个Request方法，它给我一个键/值异步。我需要全局获取此值，但它将在范围之外被定义。要做到这一点，我试图实施＆＃34;然后＆＃34;在功能，但它回来了我
TypeError: request(...).then is not a function

我的要求是......
request(options, function (error, response, body) {
console.log(body);
key = body.notification_key;
return key;
}).then(result =>{
console.log('my key is : ' + key);
});
