Question

我尝试使用node-dbox在Dropbox中列出我的内容。我与OAuth建立了连接并确实通过但是当我尝试执行client.metadata函数时，它显示了path.join错误。这是代码......

app / index.js：

// MODULE REQUIERMENTS
var dbox=require('dbox'),
    http= require('http'),
    fs=require('fs'),
    path= require('path'),
    express=require('express'),
    bodyParser = require('body-parser'),
    multipart=require('connect-multiparty');


//PATH JSON AUTH FILE 
var auth_path=path.join(__dirname,'../auth.json'),
    config = JSON.parse(fs.readFileSync(auth_path)),
    dboxapp= dbox.app(config),
    token=false,
    client = false ;

//NEW EXPRESS 
var app = new express();

// MIDDLEWARE FOR MULTIPART
var  multipartMiddleware= multipart();

//SET THE JADE VIEWS
app.set('views', __dirname + '/views');
app.set('view engine','jade'); 
app.use(bodyParser());
app.use(express.static(path.join(__dirname,'public')));

app.use(function(req,res,next) {
    if (client || token) {
        next();
    } else{
        dboxapp.requesttoken(function(status,request_token) {
            token=request_token;
            var oAuthURL = request_token.authorize_url +  '&oauth_callback=http://localhost:3000/access';
            res.redirect(oAuthURL);
        });
    };
});

app.get('/access',function (req,res) {
    dboxapp.accesstoken(token,function(status,access_token) {
        client= dboxapp.client(access_token);
        res.redirect('/album.json');
    });
});

app.get('/album',function (req,res) {
    console.log(client);
    client.metadata("/",{list:true},function (status, reply) {
        console.log(reply);
        res.render('layout',reply);
    });
});

app.get('/album.json',function (req,res) {
    client.metadata('/ ',function (status, reply) {
        res.json(reply);
    });
});

module.exports=app;

视图/ layout.jade

doctype html
html 
  head 
    title Cova Nosejs API Dropbox 
    link(rel="stylesheet",href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css")
  body
    ul 
      each file in contents
        li= file.path

控制台错误消息：

Answer 1

您可以尝试将参数明确强制转换为字符串...

app.use(express.static(path.join(__dirname.toString(),'public')));

很抱歉，这不是一个很好的答案，但有时它有助于从小做起并解决问题。这里有一些适合我的代码，使用OS X上的节点版本0.10.24和dbox版本0.6.3（当前来自npm）：

var APPKEY = '<REDACTED>',
    APPSECRET = '<REDACTED>';

var dbox = require('dbox'),
    readline = require('readline');

var app = dbox.app({
    app_key: APPKEY,
    app_secret: APPSECRET
});

app.requesttoken(function (status, requestToken) {
    console.log('Go to https://www.dropbox.com/1/oauth/authorize?oauth_token=' + requestToken.oauth_token);
    rl = readline.createInterface(process.stdin, process.stdout);
    rl.setPrompt('Press enter once you\'ve authorized: ');
    rl.prompt();
    rl.on('line', function (line) {
        app.accesstoken(requestToken, function (status, accessToken) {
            var client = app.client(accessToken);
            client.metadata('/', function (status, reply) {
                console.log(reply);
            });
        })
        rl.close();
    });
});

你可以尝试一下这段代码，看看它是否有效？如果是这样，我们可以尝试找出您的代码有何不同之处。（如果没有，我们可以尝试弄清楚您的环境有何不同。）

在检查package.json上的依赖项之后，dbox设置为此"dbox": "*"并且它没有采用最新版本（即0.6.3）。

此案例的修复是指定版本"dbox":"0.6.3"
