通過輸入流將字節流上傳到Google Drive

Question

我有字節流中的媒體內容，並且我試圖在Google雲端硬盤中上傳該流。

代碼：

private static String writeToGoogleDrive(Drive service, String title, 
     String description, String parentId, String mimeType, 
     final byte[] filename) throws IOException { 
    String URL=""; 
    File body = new File(); 
    body.setTitle(title); 
    body.setDescription(description); 
    body.setMimeType(mimeType); 




    if (parentId != null && parentId.length() > 0) { 
     body.setParents(Arrays.asList(new ParentReference().setId(parentId))); 
    } 
    try { 

    File file= service.files().insert(body, new AbstractInputStreamContent("") { 

      @Override 
      public boolean retrySupported() { 
       // TODO Auto-generated method stub 
       return false; 
      } 

      @Override 
      public long getLength() throws IOException { 
       // TODO Auto-generated method stub 
       System.out.println("the value of the length of the file is "+filename.length); 
       return filename.length; 
      } 

      @Override 
      public InputStream getInputStream() throws IOException { 
       // TODO Auto-generated method stub 
       return new ByteArrayInputStream(filename); 
      } 

     }).execute(); 

例外：它只是說，空，但我不知道（這）空是什麼。

你可以嘗試這樣的事情：

file = service.files().insert(body, new InputStreamContent(mimeType, 
new ByteArrayInputStream(filename))).execute();
