我對 和 都是nginx
新手lua
。我正在嘗試按照本教程進行操作http://leafo.net/posts/creating_an_image_server.html#installation_requirements但我一生都無法得到nginx.conf
正確的答案。
我檢查過類似的其他問題這問題出在哪裡location
,但我看不出我的程式碼有什麼問題。
這裡是nginx.conf
:
error_log stderr notice;
daemon off;
events { }
http {
include /usr/local/openresty/nginx/conf/mime.types;
server {
listen 6789;
lua_code_cache on;
location @image_server {
content_by_lua_file "serve_image.lua";
}
location ~ ^/images/(?<size>[^/]+)/(?<path>.*\.(?<ext>[a-z_]*))$ {
root cache;
try_files /$path @image_server;
}
}
}
這是serve_image.lua
程式碼
local sig, size, path, ext =
ngx.var.sig, ngx.var.size, ngx.var.path, ngx.var.ext local images_dir = "images/" -- 映像來自本地 cache_dir = "cache/" -- 映像快取的地方
local function return_not_found(msg)
ngx.status = ngx.HTTP_NOT_FOUND
ngx.header["Content-type"] = "text/html"
ngx.say(msg or "not found")
ngx.exit(0)
end
local source_fname = images_dir .. path
ngx.log(ngx.STDERR, "->>>> " .. source_fname)
-- make sure the file exists
local file = io.open(source_fname)
if not file then
ngx.log(ngx.STDERR, "Couldn't find the input file" .. source_fname)
return_not_found()
end
file:close()
local dest_fname = cache_dir .. "/" .. size .. "/" .. path
-- resize the image
local magick = require("magick")
magick.thumb(source_fname, size, dest_fname)
ngx.exec(ngx.var.request_uri)
當我運行伺服器時,我得到代碼 500。
這是終端機中的錯誤
rewrite or internal redirection cycle while redirect to named location "@image_server", client: 127.0.0.1, server: , request: "GET /images/80x80/wow.png HTTP/1.1", host: "localhost:6789"
我希望有一雙更有經驗和新鮮的眼睛能夠指出我做錯了什麼。謝謝。
