node.js + express error：无法读取undefined的属性'url'

我对Node.js相当陌生，安装它来试用DrupalChat（v7dev）模块。我相信这个问题与node.js或express相关，因为我超出了聊天模块设置加载的阶段。我试图启动聊天服务器node.js + express error：无法读取undefined的属性'url'

Extension loaded: drupalchat_nodejs.server.extension.js 
Started http server. 
    info - socket.io started 

node.js:201 
     throw e; // process.nextTick error, or 'error' event on first tick 
      ^
TypeError: Cannot read property 'url' of undefined 
    at Function.handle (/usr/local/lib/node_modules/npm/node_modules/express/node_modules/connect/lib/proto.js:105:18) 
    at Server.app (/usr/local/lib/node_modules/npm/node_modules/express/node_modules/connect/lib/connect.js:60:31) 
    at Server.serverListening (/usr/local/lib/node_modules/npm/node_modules/socket.io/node_modules/policyfile/lib/server.js:136:16) 
    at Server.g (events.js:154:14) 
    at Server.emit (events.js:64:17) 
    at Array.1 (net.js:710:10) 
    at EventEmitter._tickCallback (node.js:192:40)

我记得快递安装的时候，它给了像”警告....错误[‘网络’]也许应该是bug ['URL时面临以下输出']“（我不记得前缀）

因此，服务器试图读取（API？）变量'url'，但它目前'web'？

我有所有的模块是最新的，是我应该降级？或者有什么方法来解决这个使用另一个模块？

编辑：线201是最后很行（删除authenticatedClients [authData.authToken];）...我只是加全功能适当的上下文

var authenticateClientCallback = function (error, response, body) { 
    if (error) { 
    console.log("Error with authenticate client request:", error); 
    return; 
    } 
    if (response.statusCode == 404) { 
    if (settings.debug) { 
     console.log('Backend authentication url not found, full response info:', response); 
    } 
    else { 
     console.log('Backend authentication url not found.'); 
    } 
    return; 
    } 

    var authData = false; 
    try { 
    authData = JSON.parse(body); 
    } 
    catch (exception) { 
    console.log('Failed to parse authentication message:', exception); 
    if (settings.debug) { 
     console.log('Failed message string: ' + body); 
    } 
    return; 
    } 
    if (!checkServiceKey(authData.serviceKey)) { 
    console.log('Invalid service key "', authData.serviceKey, '"'); 
    return; 
    } 
    if (authData.nodejsValidAuthToken) { 
    if (settings.debug) { 
     console.log('Valid login for uid "', authData.uid, '"'); 
    } 
    setupClientConnection(authData.clientId, authData, authData.contentTokens); 
    authenticatedClients[authData.authToken] = authData; 
    } 
    else { 
    console.log('Invalid login for uid "', authData.uid, '"'); 
    delete authenticatedClients[authData.authToken]; 
    } 
}

，你能否告诉Node.js的：201或者更多一点。 – malletjo 2012-04-16 15:12:21

我添加了它，现在我想知道它是否在开发人员可能要求的DrupalChat配置中的非必需设置（serviceKey），但没有反映在他的代码/注释 – 2012-04-16 15:38:32

v7中并不稳定，您可能会发现这里的东西：http://drupal.org/project/issues/drupalchat?status=All&categories=全部 – malletjo 2012-04-16 15:46:02
