Question

我想用ssl嵌入yaws，但它显示错误消息，有人能告诉我如何设置SSL属性吗？

以下是我的代码

Id = "my_server",
GconfList = [{logdir, "/Users/james/Documents/workspaces/erlang/embed_yaws/log"},
           {ebin_dir, ["/Users/james/Documents/workspaces/erlang/embed_yaws/ebin"]},
           {id, Id}],
Docroot = "/Users/james/Documents/workspaces/erlang/embed_yaws/www",
SconfList = [
        {docroot, Docroot},
        {port, 4444},
        {listen, {0,0,0,0}},
        {ssl,[{keyfile, "/Users/james/Develop/yaws-2.0.2/etc/yaws/yaws-key.pem"},
          {certfile, "/Users/james/Develop/yaws-2.0.2/etc/yaws/yaws-cert.pem"},
          {depth,0},{dhfile,"/Users/james/Develop/yaws-2.0.2/etc/yaws/dhparams.pem"}]},
        {appmods, [{"/rest", myappmod1, []},{"/ws", myws, []}]}
        ],
yaws:start_embedded(Docroot, SconfList, GconfList, Id)

部分错误消息在

ssl应用程序未运行。在致电yaws:start_embedded/4之前，请按以下方式启动ssl：

application:ensure_all_started(ssl),
yaws:start_embedded(Docroot, SconfList, GconfList, Id)

如果您使用的旧版Erlang没有提供application:ensure_all_started/1，这是任何早于R16B02的版本，您可以这样开始ssl：

[application:start(App) || App <- [crypto, public_key, ssl]],
