r-使用Google文档AI(Form Parser API)进行身份验证

Question

我一直试图通过解析程序API进行身份验证，但没有成功。我已经建立了谷歌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"
)
)

我一直收到403权限被拒绝的错误。

任何帮助都将不胜感激！

我建议查看这篇关于使用R.进行谷歌身份验证的博客文章

https://cran.r-project.org/web/packages/googleAuthR/vignettes/google-authentication-types.html

目前，谷歌云没有任何R客户端库，但列出的第三方软件包应该能够提供一个起点。
