我正在使用Google腳本來獲取電子郵件的正文。我試圖只保存包含在普通YouTube電子郵件中的鏈接,該電子郵件會通知您新用戶上傳的內容。我希望只使用JavaScript保存點擊郵件中包含的圖像時所遵循的鏈接。下面看到的是郵件的一部分,外觀的例子:通過電子郵件過濾掉YouTube視頻的鏈接

電子郵件的內容是這樣的:

這裏的問題是,如何我篩選後的網址從這樣的電子郵件,並且它看起來像文本3D被添加到網址,這是使網站無效,所以我也需要從網址中刪除。我怎麼能做到這一點的任何想法?

編輯:

這裏是我使用的,它缺少解析數據的代碼:

function processInbox() { 
    // get all threads in inbox 
    var label = GmailApp.getUserLabelByName("Social/YouTube/Dubstep"); 
    var doneLabel = GmailApp.getUserLabelByName("Social/YouTube/Dubstep (added)"); 
    var messages = label.getThreads(); 
    var max = Math.min(messages.length,1); 
    for(var i = 0; i < max; ++i) { 
    var email = messages[i].getMessages()[0]; 
    var contents = email.getBody(); 

    //PARSE HERE 
    var xml = Xml.parse(contents,true); 
    Logger.log(xml); 
    GmailApp.sendEmail('MY EMAIL', 'Xml Contents', Logger.getLog()); 



    //messages[i].markRead(); 
    //messages[i].removeLabel(label).addLabel(doneLabel); 
    } 
}; 

EDIT2:新代碼:

function processInbox() { 
    // get all threads in inbox 
    var label = GmailApp.getUserLabelByName("Social/YouTube/Dubstep"); 
    var doneLabel = GmailApp.getUserLabelByName("Social/YouTube/Dubstep (added)"); 
    var messages = label.getThreads(); 
    var max = Math.min(messages.length,5); 
    for(var i = 0; i < max; ++i) { 
    var email = messages[i].getMessages()[0]; 
    var contents = email.getBody(); 
    var st = contents.indexOf('<a href="http://www.youtube.com/watch?v='); 
    var str1 = contents.substr(st+9,80); 
    var end = str1.indexOf('&amp'); 
    var link = str1.substring(0,end); 
    Logger.log(link); 
    GmailApp.sendEmail('EMAIL', 'Xml Contents', Logger.getLog()); 

    Logger.clear(); 

    //messages[i].markRead(); 
    //messages[i].removeLabel(label).addLabel(doneLabel); 
    }

我想最好的辦法就是使用XML service來解析HTML並從那裏獲取元素。

documentation here,設置寬大參數true

我前一段時間使用類似的方法in this post,你可以看到的想法...


編輯: 我沒有」 t成功地用這種方法... 我嘗試了別的使用字符串操作:

... 
var contents = email.getBody(); 
var st = contents.indexOf('<a href="http://www.youtube.com/watch?v='); 
var str1 = contents.substr(st+9,80); 
var end = str1.indexOf('&amp'); 
var link = str1.substring(0,end); 
Logger.log(link);  

它適用於這種情況下,你將不得不檢查它是否一直工作。

注:我測試了來自YouTube通過電子郵件發送給其他共享鏈接,它似乎每次;-)

這種方法是不是真的使用功能在谷歌的腳本,然後是它的工作?我使用getBody()更新了其中一封電子郵件的確切輸出。實際上是否有使用Google腳本的內置函數來獲取XML數據的方法? – ComputerLocus 2013-03-09 22:29:38

?? XML服務是Google腳本中的默認服務......我並不真正瞭解您的評論。抱歉,如果我錯過了什麼。 – 2013-03-09 22:37:43

我添加了我目前正在使用的代碼。有沒有什麼方法可以像我現在這樣使用代碼,還是必須完全改變它來使用你的XML方法?如果我必須改變它,我會怎樣做呢?我對JavaScript和Google腳本非常陌生,所以我一直在尋找一個基本的解決方案,但我想這不會是一個? – ComputerLocus 2013-03-09 22:42:03
