OpenResty作为WebSocket服务器如果想要支持wss://协议应该如何配置？

u201313922

Hi,

OpenResty提供了作为WebSocket服务器支持ws://协议的配置方法：

ngx.conf:

#########################################################

user root; # Running in root

worker_processes auto; # Defines the number of worker processes.

# Setting it to auto autodetects the num of CPU core numbers

error_log logs/error.log info;

events {

worker_connections 512; # Sets the maximum number of simultaneous connections

# that can be opened by a worker process.

}

http {

include mime.types; # necessary

default_type application/octet-stream; # Defines the default MIME type of a response.

lua_package_path '/usr/local/openresty/lualib/?.lua;;';

sendfile on; # To applications except for high IOPS, it must be set to on,

# otherwise the pictures may cannot be showed

keepalive_timeout 75s; # the keep-alive client connection will stay open on the serverside during 75s

server {

listen 80; # port 80

server_name websocket_server;

lua_code_cache off;

location /websocket_server{

content_by_lua_file lua/websocket_server.lua;

}

websocket_server.lua: 与github上的相同

  local server = require "resty.websocket.server"

    local wb, err = server:new{
        timeout = 5000,  -- in milliseconds
        max_payload_len = 65535,
    }
    if not wb then
        ngx.log(ngx.ERR, "failed to new websocket: ", err)
        return ngx.exit(444)
    end

    local data, typ, err = wb:recv_frame()

    if not data then

            return
        end
    elseif typ == "pong" then
        -- just discard the incoming pong frame

    else
        ngx.log(ngx.INFO, "received a frame of type ", typ, " and payload ", data)
    end

    wb:set_timeout(1000)  -- change the network timeout to 1 second

    bytes, err = wb:send_text("Hello world")
    if not bytes then
        ngx.log(ngx.ERR, "failed to send a text frame: ", err)
        return ngx.exit(444)
    end

    bytes, err = wb:send_binary("blah blah blah...")
    if not bytes then
        ngx.log(ngx.ERR, "failed to send a binary frame: ", err)
        return ngx.exit(444)

    local bytes, err = wb:send_close(1000, "enough, enough!")
    if not bytes then

但是如果想让WebSocket服务器支持wss://协议应该如何配置呢？应该做哪些改动？
