如何逐行讀取存儲在java的blobstore上的文件？

Question

我已經使用在以下鏈接uploding上Blob存儲的文件中給出代碼 https://developers.google.com/appengine/docs/java/blobstore/overview#Writing_Files_to_the_Blobstore

Answer 1

在鏈接中給出的示例中，您發佈的有什麼不對？

// Later, read from the file using the file API 
     lock = false; // Let other people read at the same time 
     FileReadChannel readChannel = fileService.openReadChannel(file, false); 

    // Again, different standard Java ways of reading from the channel. 
     BufferedReader reader = new BufferedReader(Channels.newReader(readChannel, "UTF8")); 
     String line = reader.readLine(); 
    // line = "The woods are lovely dark and deep."
