GAS openByUrl（）错误：无效参数：url

Question

为什么这段代码：

var target = createDuplicateDocument(template, docName);
var targetDocId = target.getId();
var link = target.getUrl();
var myVariable = DocumentApp.openByUrl(newDocLink).getText();

产生此错误？

14-02-01 11:02:37:973 BRST] DocumentApp.openByUrl([https://docs.google.com/open?id=1kQWDgh7Qe80pCuvs2VQjPhJGCSk9KXXXs4Nqt2pLH1c]) [0 segundos]
[14-02-01 11:02:38:931 BRST] Falha na execução: Argumento inválido: url (line 238, file "mainScript") [2.796 segundos de tempo de execução total]

我也试过var myVariable = DocumentApp.openByUrl(newDocLink[0]).getText();但它没有用。我知道我可以使用openById，但我想让openByUrl正常工作。谢谢！

Answer 1

newDocLink永远不会在上面用作参数的地方定义。
