使用API 将文件上传到Google驱动器，错误403

问题描述 投票：2回答：1

我想将zip文件上传到Google驱动器。我使用Java快速入门（https://developers.google.com/drive/v3/web/quickstart/java）作为基础。该代码有效。我通过以下代码对其进行了修改]

File fileMetadata = new File();
fileMetadata.setName("My Report");
fileMetadata.setMimeType("application/vnd.google-apps.spreadsheet");

java.io.File filePath = new java.io.File("files/report.csv");
FileContent mediaContent = new FileContent("text/csv", filePath);
File file = driveService.files().create(fileMetadata, mediaContent)
.setFields("id")
.execute();
System.out.println("File ID: " + file.getId());

现在我的编译器显示错误403。

我也建议从Arrays.asList（DriveScopes。DRIVE_METADATA_READONLY）更改SCOPE；到Arrays.asList（DriveScopes。DRIVE）;

这里有Google Drive API SCOPES的更多文档。

  1. [更改范围时，请记住删除存储在项目的tokens文件夹中的“ StoredCredential”文件。

  2. [再次运行程序，这样您将提示到提供Google登录凭据到允许程序来组织，添加和编辑文件在Google云端硬盘上。

  3. 在身份验证过程中授予权限时，确保您允许程序到组织，添加和编辑文件在Google云端硬盘上。

  4. 认证过程将生成一个新的“ StoredCredential”文件，该文件将包括您指定的新范围。

这对我有用，希望它也对您有用。
