我正在尝试使用R和RcppRedis连接到需要SSL和密码的redis数据库。我在一个Docker容器中构建了Renv，在这个容器中我编译了启用了SSL的hiredis，但是虽然我可以连接到我的生产数据库，但我不能与它交互。
为了确认它在没有密码或ssl的情况下工作，我可以使用以下命令连接到同一Docker网络上的redis本地示例并与之交互：

library(RcppRedis)
r <- new(Redis, "172.18.0.4")
r$exec("keys *")

## <lots of keys print here>

字符串
类似地，我可以连接生产数据库，但实际上无法与之交互。我怀疑是因为我只需要设置ssl=1，但我不知道在哪里，也不知道如何发送我的密码。
下面是我尝试过的：

redis <- new(Redis, "<my-redis-host>", port=6369, password="<my-password>", ssl="1")
## Error: Recieved NULL reply; potential connection loss with Redis

redis <- new(Redis, "<my-redis-host>", port=6369, auth="<my-password>", ssl="1")
## Error: Recieved NULL reply; potential connection loss with Redis

redis <- new(Redis, "<my-redis-host>", port=6369, ssl="1")
## Error: Recieved NULL reply; potential connection loss with Redis

redis <- new(Redis, "<my-redis-host>", port=6369)
redis$exec("auth <my-password>")
## Error: Recieved NULL reply; potential connection loss with Redis

型
我几乎没什么主意了。我错过了什么？这种方式是否比我想象的更复杂，并且我需要实际传递证书文件？
编辑：我可以使用python演示连接需要一个ssl标志：

from redis import Redis
redis = Redis(
  host="<my-redis-host>", 
  port=6369, 
  password="<my-password>", 
  ssl=True
)
redis.ping()
## True

从构建日志中，我可以看到RcppRedis找到了hiredis dll文件，并成功加载了自己的库。相关文件如下。
我的文件夹：

    apt-utils \

  ldconfig

RUN R -e "install.packages('RcppRedis', repos='http://cran.rstudio.com/', INSTALL_opts=c('--no-lock'))"
