使用的node.js和google-API

Question

我的代码如下获得Gmail收件箱，（上述代码作为在谷歌开发者网站的NodeJS的例子中给出是相同。）

function listLabels(auth) { 

     var gmail = google.gmail({ auth: auth, version: 'v1' }); 

     var emails = gmail.users.messages.list({ 
      includeSpamTrash: false, 
      maxResults: 500, 
      q: "", 
      userId: 'me' 
     }, function (err, results) { 
      console.log(results.messages); 
     }); 
    } 

我得到对象数组含有ID和线程ID

现在，如果我输入这些ID

到这些

function getMessage(messageId,auth) { 
    var requestt = google.gmail({ auth: auth, version: 'v1' }).users.messages.get({ 
    'userId': 'me', 
    'id': messageId 
    }); 
    console.log(requestt) 
    requestt.execute(function(response){ 
    console.log(response); 
    }); 
} 

我得到错误，

你可以使用回叫你做同样的方式，当你列出的消息：

function getMessage(messageId, auth) { 
    var gmail = google.gmail({ auth: auth, version: 'v1' }); 

    gmail.users.messages.get({ 
    'userId': 'me', 
    'id': messageId 
    }, function (err, result) { 
    console.log(result); 
    }); 
}
