Dropbox令牌API会返回“缺少客户端凭据”。在Node.js中 [英] Dropbox token API returns "Missing client credentials" in Node.js

问题描述

我尝试在普通的Node.js中使用Dropbox Core API。

I tried use Dropbox Core API in plain Node.js.

编程为：

1. 用户打开授权页面并获取代码。


2. 用户将代码输入到应用中。


3. 应用将其发送到Dropbox API


4. API返回令牌。

1. User opens authorize page and get code.
2. User inputs the code to app.
3. App send it to Dropbox API.
4. API returns token.

但是我无法令牌化，API返回错误消息缺少客户端凭据。

But I cannot token and API returns error with the message "Missing client credentials".

• 我的代码在这里： https://gist.github.com/ginpei/65890135d323f18207c0

我应该如何编写代码以获得令牌？

How should I write code to get token?

谢谢。

编辑，从链接的摘要中添加代码：

EDIT Adding code from the linked gist:

// About API:
// https://www.dropbox.com/developers/core/docs#oa2-authorize
// https://www.dropbox.com/developers/core/docs#oa2-token

var config = require('./config.json');
// OR...
// var config = {
//  'appKey': 'xxxxxxxxxxxxxxx',
//  'secretKey': 'xxxxxxxxxxxxxxx'
// };

var readline = require('readline');
var https = require('https');
var querystring = require('querystring');

// Show authrize page
var url = 'https://www.dropbox.com/1/oauth2/authorize?' +
    querystring.stringify({ response_type:'code', client_id:config.appKey });
console.log('Open and get auth code:\n\n', url, '\n');

// Get the auth code
var rl = readline.createInterface(process.stdin, process.stdout);
rl.question('Input the auth code: ', openRequest);  // defined below

function openRequest(authCode) {
    var req = https.request({
        headers: { 'Content-Type': 'application/json' },
        hostname: 'api.dropbox.com',
        method: 'POST',
        path: '/1/oauth2/token'
    }, reseiveResponse);  // defined below

    // ################################
    // Send code
    // (maybe wrong...)
    var data = JSON.stringify({
        code: authCode,
        grant_type: 'authorization_code',
        client_id: config.appKey,
        client_secret: config.secretKey
    });
    req.write(data);
    // ################################
    req.end();

    console.log('Request:');
    console.log('--------------------------------');
    console.log(data);
    console.log('--------------------------------');
}

function reseiveResponse(res) {
    var response = '';
    res.on('data', function(chunk) { response += chunk; });

    // Show result
    res.on('end', function() {
        console.log('Response:');
        console.log('--------------------------------');
        console.log(response);  // "Missing client credentials"
        console.log('--------------------------------');
        process.exit();
    });
}

推荐答案

这部分代码是错误：

var data = JSON.stringify({
    code: authCode,
    grant_type: 'authorization_code',
    client_id: config.appKey,
    client_secret: config.secretKey
});
req.write(data);

您要发送的是JSON编码的正文，但API希望使用表单编码。

You're sending a JSON-encoded body, but the API expects form-encoding.

我个人建议使用类似 request ，以便更轻松地发送表单编码的数据。 （请参阅此处的用法： https://github.com/smarx /othw/blob/master/Node.js/app.js 。）

I'd personally suggest using a higher-level library like request to make it easier to send form-encoded data. (See my use here: https://github.com/smarx/othw/blob/master/Node.js/app.js.)

但是您应该可以在此处使用querystring编码。只需将 JSON.stringify 替换为 querystring.stringify ：

But you should be able to use querystring encoding here. Just replace JSON.stringify with querystring.stringify:

var data = querystring.stringify({
    code: authCode,
    grant_type: 'authorization_code',
    client_id: config.appKey,
    client_secret: config.secretKey
});
req.write(data);
