javascript - 如何使用 Request 库和 Bluebird 发送 post 请求？

Question

所以这是我的设置:

var Promise = require("bluebird");
var request = Promise.promisify(require('request'));

这个有效:

request('url')

它返回一个 promise

这不是:

request.post('url', {form: {type: 'artist'}})

给我这个错误:

TypeError: Object function promisified(_arg0,_arg1) { ... }has no method 'post'

关于如何使这项工作有任何想法吗？执行此操作的正确方法是什么？

Answer 1

当您 promise 请求返回时，您只 promise 返回的函数。相反 - 使用 promisifyAll 来 promise 整个对象。因为 request 是你没有得到错误。

var Promise = require("bluebird");

var request = Promise.promisifyAll(require('request')); // this will work
