使用 Google Document AI（表单解析器 API）进行身份验证

Question

我一直在尝试从解析器 API 进行身份验证，但没有成功。 我已经设置了 google 服务帐户并创建了两个密钥。我已经设置了所有者角色并下载了凭证 json 文件。

googleAuthR::gar_auth_service("D:/898 sample/document ai/form-898-scan-bd4b8b48b570.json")
library(daiR)

response1 <- dai_sync("D:/test file.pdf"
                      ,
                      proj_id = get_project_id(path = "D:/crudentialabc123.json"),
                      proc_id = "e4xxxxxx",
                      loc = "us",
                      token = dai_token(
                        path = Sys.getenv("GSC_AUTH_FILE")
                        # scopes = "https://googleapis.com/auth/cloud-platform"
                        )
                      )

我不断收到 403 权限被拒绝错误。

任何帮助将不胜感激！

我建议您使用R.

https://cran.r-project.org/web/packages/googleauthr/vignettes/google-authentication-ytypes.html

当前，Google Cloud cloud没有任何r的客户端库，但是列出的第三方软件包应该能够提供一个起点。
