我已经配置了一个Elixir应用程序并定义了管理路由。但是,尝试访问任何路由时出现以下错误。
(退出)引发了异常: **(ArgumentError)参数错误 (crypto):crypto.hmac_nif(:sha256,{:system,“ Zpumk6KLEY8Qx826qspHhYrpTpDswFzHL / 64aJWqhPyYZQWbV3hWq + nUIPQRMwLn”}, << 48,70,98,86,85,68,57,56,0,0,0,1 >>) (crypto)crypto.erl:925 :: crypto.hmac / 6 (插件)lib / plug / crypto / key_generator.ex:64:Plug.Crypto.KeyGenerator.generate / 7 (插件)lib / plug / crypto / key_generator.ex:50:Plug.Crypto.KeyGenerator.with_cache / 3 (插件)lib / plug / session / cookie.ex:88:Plug.Session.COOKIE.get / 3 (插件)lib / plug / session.ex:75:Plug.Session.fetch_session / 1中的匿名fn / 5 (插件)lib / plug / debugger.ex:195:Plug.Debugger.maybe_fetch_session / 1 (插件)lib / plug / debugger.ex:150:Plug.Debugger.render / 6 (插件)lib / plug / debugger.ex:129:Plug.Debugger。捕获 / 5 (my_app)lib / my_app_web / endpoint.ex:1:MyAppWeb.Endpoint.call/2 (插件)lib / plug / adapters / cowboy / handler.ex:15:Plug.Adapters.Cowboy.Handler.upgrade / 4

有人,请帮忙吗?

如医生所说,
由于此存储使用加密功能,因此需要您在连接中设置:secret_key_base字段。只需使用插头即可轻松实现:
似乎您没有在代码中执行此部分。
