Most of these involve lua
Add to location
Return 200 with text
add_header Content-Type text/plain;
return 200 "hi";
default_type 'text/plain';
content_by_lua_block {
ngx.req.read_body()
local request_body = ngx.req.get_body_data()
ngx.say(request_body)
ngx.say('hello')
ngx.say(ngx.var.arg_id)
if string.find(ngx.var.request_body, "eth") then
ngx.say('contains')
end
if ngx.re.match(ngx.var.request_body, "feth") then
ngx.say('contains2')
end
Loging vars in lua to error log
ngx.log(ngx.ERR, 'mytest or var');
p = 666
d = "23.42"
payload='{"d":[{"pres":'..(p)..',"temp":"'..(d)..'"}]}'
t = cjson.decode(payload)
print(t.d[1].temp) -- prints "23.42"
Getting Headers
local h = ngx.req.get_headers()
for k, v in pairs(h) do
ngx.say(k, ": ", v)
end
local redis = require "nginx.redis"
local rdb = redis:new()
rdb:set_timeout(1000) -- 1 sec
local ok, err = rdb:connect("127.0.0.1", 6379)
if not ok then
ngx.say("failed to connect: ", err)
return
end
if res ~= ngx.var.http_authorization then
ngx.say("Failed http authorization.")
return
end
ngx.encode_base64("myuser:pass")
if res ~= ngx.var.http_authorization then
ngx.say("Failed http authorization.")
return
end
