java - 使用 API 和错误 403 将文件上传到 Google 驱动器

Question

我想将 zip 文件上传到 Google 驱动器。我使用 Java Quickstart ( https://developers.google.com/drive/v3/web/quickstart/java) 作为基础。该代码有效。我是通过下面的代码修改的

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。

Answer 1

我还建议更改 Arrays.asList(DriveScopes.DRIVE_METADATA_READONLY) 中的 SCOPE;到 Arrays.asList(DriveScopes.DRIVE);

这是关于 Google Drive API SCOPES 的更多文档.

1. 更改 SCOPE 时，请记住删除存储在项目的 tokens 文件夹中的“StoredCredential”文件。

2. 再次运行您的程序，这样您将提示提供 Google 登录凭据以允许> 用于在 Google Drive 上组织、添加和编辑文件的程序。

3. 确保在身份验证过程中授予权限时，您允许您的程序组织、添加和编辑 Google Drive 上的文件。

   <

4. 身份验证过程将生成一个新的“StoredCredential”文件，该文件将包含您的<您指定的 strong>新范围。

这对我有用，希望对你也有用。
