Question

所以继承我的设置：

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

这有效：

request('url')

它返回一个承诺

这不是：

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

给了我这个错误：

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

关于如何使这项工作的任何想法？这样做的正确方法是什么？

Answer 1

当您宣传请求时，您只会返回已退回的函数。相反 - 使用promisifyAll来宣传整个对象。由于request并非您都没有收到错误。

var Promise = require("bluebird");

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

如何使用请求库和Bluebird发送帖子请求？
