使用Google云端硬盘+ Java中的Google Spreadsheet API创建电子表格

Question

我已经通过Google官方文档开发人员指南Spreadsheet API中提到的简单Java代码在My Google Drive帐户的现有电子表格中成功创建了一个新的工作表,但我想创建一个新的电子表格通过java代码在我的Google云端硬盘帐户中.在上面提到的链接中,他们没有提到任何示例代码.我经历过许多链接,但没有得到怎么办？我已经在Spreadservice类中看到了不同的方法.

我没有了解如何使用Google Spreadsheet API？

Answer 1

经过一些研究后我发现这个答案很简单.我们无法使用Google Spreadsheet API在Google 云端硬盘中创建新的电子表格.

注意:我们可以通过Google Spreadsheet API在已存在的Google云端硬盘电子表格中创建新的工作表,但无法使用电子表格API创建新的电子表格.

要创建和上传新的电子表格或Google支持的任何其他类型的文档,我们必须使用Google Drive api.

这就是我要找的.通过这个我们可以使用谷歌驱动器API在谷歌驱动器中创建一个新的电子表格.

    DocsService docsService = new DocsService("MySampleApplication-v3");
    docsService.setUserCredentials(USERNAME, PASSWORD);
    URL GOOGLE_DRIVE_FEED_URL = new URL("https://docs.google.com/feeds/default/private/full/");
    DocumentListEntry documentListEntry = new com.google.gdata.data.docs.SpreadsheetEntry();
    documentListEntry.setTitle(new PlainTextConstruct("Spreadsheet_name"));
    documentListEntry = docsService.insert(GOOGLE_DRIVE_FEED_URL, documentListEntry);

为了创建新的电子表格,我们必须创建new SpreadsheetEntry()对象,对于我们必须创建对象的任何其他文档new DocumentEntry().

现在如果我们必须在谷歌驱动器上传任何类型的文件(xls,doc,图像等),我们可以这样做

//File upload in google drive
        DocumentListEntry uploadFile = new DocumentListEntry();
        uploadFile.setTitle(new PlainTextConstruct("FILE_NAME_DISPLAY_IN_DRIVE"));
        uploadFile.setFile(new File("FILE_PATH"), "MIME_TYPE_OF_FILE");
        uploadFile = docsService.insert(GOOGLE_DRIVE_FEED_URL, uploadFile);
