【问题描述】：
我正在构建一个以 SQL DB 作为后端的 WebApp。我在 Azure 上部署这两个部分，作为 Azure Webapp 和 SQL Server。
SQL 服务器使用 Azure AD (AAD) 进行保护。因此，只有组中的用户才能访问数据库。
所以我正在尝试设置 Webapp 登录用户并收集他的访问令牌的工作流程。然后使用token查询SQL server。
我已在 AAD 中注册了该应用程序，它被授权读取用户 ID 并冒充用户。
我有以下在本地工作的代码。但我无法让它在本地部署在 Docker 映像中工作。
# app file

useShinyjs()
opts <- parseQueryString(req$QUERY_STRING)
if( is.null(opts$code) ) {
auth_uri <- build_authorization_uri(
resource = config$resource,
tenant = config$tenant,
app = config$app,
redirect_uri = redirect,
# version = 2,
prompt = 'login')
redir_js <- sprintf('location.replace(\"%s\");', auth_uri)
tags$script(HTML(redir_js))
} else {
