Replacing node request.post with request-promise
提问by VB_
I have:I used Node.js request module to get authorization token:
我有：我使用 Node.js 请求模块来获取授权令牌：
Working code without promise
没有承诺的工作代码
var request = require('request');
var querystring = require('querystring');
var requestOpts = querystring.stringify({
client_id: 'Subtitles',
client_secret: 'X............................s=',
scope: 'http://api.microsofttranslator.com',
grant_type: 'client_credentials'
});
request.post({
encoding: 'utf8',
url: "https://datamarket.accesscontrol.windows.net/v2/OAuth2-13",
body: requestOpts
}, function(err, res, body) { //CALLBACK FUNCTION
var token = JSON.parse(body).access_token;
amkeAsyncCall(token);
});
I want:It takes some time to get that token. In turn I need makeAsyncCallfrom getToken callback. So I decide to use a request-promisefrom here.
我想要：获得该令牌需要一些时间。反过来，我需要makeAsyncCall从 getToken 回调。所以我决定使用 a request-promisefrom here。
Problem:request-promise seems don't work for me at all.
问题：请求-承诺似乎对我根本不起作用。
The same (not working) code with promise:
与承诺相同（不工作）的代码：
var rp = require('request-promise');
var querystring = require('querystring');
var requestOpts = {
encoding: 'utf8',
uri: 'https://datamarket.accesscontrol.windows.net/v2/OAuth2-13',
method: 'POST',
body: querystring.stringify({
client_id: 'Subtitles',
client_secret: 'Xv2Oae6Vki4CnYcSF1SxSSBtO1x4rX47zhLUE/OqVds=',
scope: 'http://api.microsofttranslator.com',
grant_type: 'client_credentials'
})
};
rp(requestOpts)
.then(function() {
console.log(console.dir);
})
.catch(function() {
console.log(console.dir);
});

I use the node.js package "unirest".
我使用 node.js 包“unirest”。
var unirest = require('unirest');
var dataObj = {};
var Request = unirest.post('http://127.0.0.1:' + port + '/test/4711DE/de');
Request.headers({ 'Accept': 'application/json' })
.type('json')
.send(JSON.stringify(dataObj))
.auth({
user: 'USERNAME',
pass: 'PASSWORD',
sendImmediately: true
})
.end(function (response) {
assert.equal(200, response.statusCode);
// ...
});

I tested your code with the latest version of Request-Promise(0.3.1) and it works fine.
我使用最新版本的Request-Promise(0.3.1)测试了您的代码，它运行良好。
Just the last part of logging to the console was not correct. Use:
只是登录到控制台的最后一部分是不正确的。利用：
rp(requestOpts)
.then(function(body) {
console.dir(body);
})
.catch(function(reason) {
console.dir(reason);
});

You could set the jsonattribute in requestOptsbe true, it worksfor me.
你可以设置json在属性requestOptsBE true，它的作品对我来说。
var rp = require('request-promise');
var querystring = require('querystring');
var requestOpts = {
encoding: 'utf8',
uri: 'https://datamarket.accesscontrol.windows.net/v2/OAuth2-13',
method: 'POST',
json: true,
body: {
client_id: 'Subtitles',
client_secret: 'Xv2Oae6Vki4CnYcSF1SxSSBtO1x4rX47zhLUE/OqVds=',
scope: 'http://api.microsofttranslator.com',
grant_type: 'client_credentials'
}
};
rp(requestOpts)
.then(function() {
console.log(console.dir);
})
.catch(function() {
console.log(console.dir);
});

I had the same issue I just added this property
headers = { 'Content-Type': 'application/json' };
我有同样的问题，我刚刚添加了这个属性
headers = { 'Content-Type': 'application/json' };
var requestOpts = {
encoding: 'utf8',
uri: 'https://datamarket.accesscontrol.windows.net/v2/OAuth2-13',
method: 'POST',
headers = { 'Content-Type': 'application/json' };
body: JSON.stringify({
client_id: 'Subtitles',
client_secret: 'Xv2Oae6Vki4CnYcSF1SxSSBtO1x4rX47zhLUE/OqVds=',
scope: 'http://api.microsofttranslator.com',
grant_type: 'client_credentials'
})
};
