这是我的解决方案,不使用表,节省了一些内存:
function Sendfile(sck, filename, sentCallback)
if not file.open(filename, "r") then
sck:close()
return
end
local function sendChunk()
local line = file.read(512)
if line then
sck:send(line, sendChunk)
else
file.close()
collectgarbage()
if sentCallback then
sentCallback()
else
sck:close()
end
end
end
sendChunk()
end
srv = net.createServer(net.TCP)
srv:listen(80, function(conn)
conn:on("receive", function(sck, req)
sck:send("HTTP/1.1 200 OK\r\n" ..
"Server: NodeMCU on ESP8266\r\n" ..
"Content-Type: text/html; charset=UTF-8\r\n\r\n",
function()
Sendfile(sck, "head.html", function() Sendfile(sck, "body.html") end)
end)
end)
end)
这是用于服务单个文件:
function Sendfile(client, filename)
if file.open(filename, "r") then
local function sendChunk()
local line = file.read(512)
if line then
client:send(line, sendChunk)
else
file.close()
client:close()
collectgarbage()
end
end
client:send("HTTP/1.1 200 OK\r\n" ..
"Server: NodeMCU on ESP8266\r\n" ..
"Content-Type: text/html; charset=UTF-8\r\n\r\n", sendChunk)
else
client:send("HTTP/1.0 404 Not Found\r\n\r\nPage not found")
client:close()
end
end
srv = net.createServer(net.TCP)
srv:listen(80, function(conn)
conn:on ("receive", function(client, request)
local path = string.match(request, "GET /(.+) HTTP")
if path == "" then path = "index.htm" end
Sendfile(client, path)
end)
end)
