產生java.io.IOException在com.google.appengine.api.files.FileServiceImpl.translateException（FileServiceImpl.java:586）

Question

我得到當地下面的錯誤以及生產。我正在使用SDK1.6.3。 @production我還在「google api console」的Team標籤中添加了XXXXXXXX@appspot.gserviceaccount.com。

FileService fileService = FileServiceFactory.getFileService(); 
    GSFileOptionsBuilder optionsBuilder = new GSFileOptionsBuilder() .setBucket(BUCKETNAME) .setKey(FILENAME) .setMimeType("text/html") .setAcl("public_read") .addUserMetadata("myfield1", "my field value"); 
    AppEngineFile writableFile = fileService.createNewGSFile(optionsBuilder.build()); 

這是我的代碼，我在

AppEngineFile writableFile = fileService.createNewGSFile(optionsBuilder.build()); 

得到錯誤我用上面的代碼並獲得以下錯誤..

請幫助我。在此先感謝 - 至尊康德

Answer 1

請升級到Java SDK的最新版本（1.8.0爲2013年5月18日的）：https://developers.google.com/appengine/downloads#Google_App_Engine_SDK_for_Java

當前的SDK版本不再包含你列出的堆棧跟蹤在bug：

at com.google.appengine.api.files.dev.LocalFileService.throwError(LocalFileService.java:196) 

Answer 2

我不得不去爲com.google.appengine.api.files.GSFileOptions的源代碼（GAE Java SDK中1.8.1.1），才能找出一個有效的水桶名應該。

37行：this.fileName = FileServiceImpl.GS_FILESYSTEM_PREFIX +桶+ 「/」 +密鑰;

的Javadoc沒有提供關於桶的格式的任何信息。在這種情況下，請不要在您的存儲桶名稱末尾包含/ gs /前綴或/（如我在做的那樣）。如果您使用了其他API（如BlobStor API），這可能會令人困惑，因爲它們需要/ gs /前綴。

我得到了與1.8.1.1相同的異常和堆棧跟蹤，所以壞的桶名稱可能是原因。

此外，你可能想嘗試Google Cloud Storage Client Library。
