Google Closure编译器不会返回任何编译代码？

Question

在Stack Overflow的另一个问题中，我遇到了一个非常有用的代码片段，可以将代码发送到Google Closure编译器，该代码片段可以很好地缩小JavaScript文件。

然而，我面临的问题是，它不会返回任何编译的代码，我不希望它这样做。

代码：

这工作，即返回精缩代码：

Dim script = "function test(name) {alert(name);}test('New user');" 

这一个，而另一方面，不返回任何东西。统计数据被发送，但没有编制的数据...：

Dim script = "function test(name) {alert(name);}" 

休息，实际上做的工作代码：

Dim Data = String.Format(ClosureWebServicePOSTData, HttpUtility.UrlEncode(script)) 

    _Result = New StringBuilder 
    _HttpWebRequest = DirectCast(WebRequest.Create(ClosureWebServiceURL), HttpWebRequest) 
    _HttpWebRequest.Method = "POST" 
    _HttpWebRequest.ContentType = "application/x-www-form-urlencoded" 
    '//Set the content length to the length of the data. This might need to change if you're using characters that take more than 256 bytes 
    _HttpWebRequest.ContentLength = Data.Length 
    '//Write the request stream 
    Using SW As New StreamWriter(_HttpWebRequest.GetRequestStream()) 
     SW.Write(Data) 
    End Using 


    Dim response As WebResponse = _HttpWebRequest.GetResponse() 

    Using responseStream As Stream = response.GetResponseStream 
     Dim encoding As Encoding = System.Text.Encoding.GetEncoding("utf-8") 
     Using readStream As New StreamReader(responseStream, encoding) 
      Dim read(256) As Char 
      Dim count As Integer = readStream.Read(read, 0, 256) 
      While count > 0 
       Dim str As New String(read, 0, count) 
       _Result.Append(str) 
       count = readStream.Read(read, 0, 256) 
      End While 
     End Using 
    End Using 

可能是什么casue呢？我很想知道。

可能使用ADVANCED_OPTIMIZATIONS设置？该功能可能已被剥离，因为它已定义，但从未使用。
