From 31e0667a4a53a238d0321194b57b083bd74c0a5b Mon Sep 17 00:00:00 2001 From: Jeija Date: Thu, 18 Feb 2016 11:38:47 +0100 Subject: Add Lua interface to HTTPFetchRequest This allows mods to perform both asynchronous and synchronous HTTP requests. Mods are only granted access to HTTP APIs if either mod security is disabled or if they are whitelisted in any of the the secure.http_mods and secure.trusted_mods settings. Adds httpfetch_caller_alloc_secure to generate random, non-predictable caller IDs so that lua mods cannot spy on each others HTTP queries. --- builtin/game/misc.lua | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'builtin/game') diff --git a/builtin/game/misc.lua b/builtin/game/misc.lua index bacadf18f..d0e67bd88 100644 --- a/builtin/game/misc.lua +++ b/builtin/game/misc.lua @@ -178,3 +178,22 @@ function core.raillike_group(name) end return id end + +-- HTTP callback interface +function core.http_add_fetch(httpenv) + httpenv.fetch = function(req, callback) + local handle = httpenv.fetch_async(req) + + local function update_http_status() + local res = httpenv.fetch_async_get(handle) + if res.completed then + callback(res) + else + core.after(0, update_http_status) + end + end + core.after(0, update_http_status) + end + + return httpenv +end -- cgit v1.2.3
