Refactor the Lua HTTP client to defer initialization. core.httpclient()
no longer initializes the internal HTTP client immediately. Instead,
initialization now occurs within hlua_httpclient_send() when a request
method (e.g., get, put, head) is invoked.
The HTTPClient class now serves as a factory for accessing methods, while
a new class, HTTPClientRequest, has been introduced to represent individual
requests and manage the HTTP client lifecycle.
This change allows multiple requests to be executed using a single
HTTP client instance:
local hc = core.httpclient()
local res1 = hc:get({url = "...", headers = ...})
local res2 = hc:post({url = "...", headers = ...})
local res3 = hc:put({url = "...", headers = ...})
This refactor maintains backward compatibility, as existing scripts that
instantiate a new core.httpclient() for every request will continue to
work as expected.
The 'dst' optionnal field on a httpclient request can be used to set an
alternative server address in the haproxy address format. Which means it
could be use with unix@, ipv6@ etc.
Should fix issue #1471.
This patch allows to replace the host header generated by the
httpclient instead of adding a new one, resulting in the server replying
an error 400.
The host header is now generated from the uri only if it wasn't found in
the list of headers.
Also add a new request in the VTC file to test this.
This patch must be backported in 2.5.
Improve the httpclient reg-tests to test the streaming,
The regtest now sends a big payload to vtest, then receive a payload
from vtest and send it again.
Add support for HEAD/PUT/POST/DELETE method with the lua httpclient.
This patch use the httpclient_req_gen() function with a different meth
parameter to implement this.
Also change the reg-test to support a POST request with a body.
httpclient_req_gen() takes a payload argument which can be use to put a
payload in the request. This payload can only fit a request buffer.
This payload can also be specified by the "body" named parameter within
the lua. httpclient.
It is also used within the CLI httpclient when specified as a CLI
payload with "<<".
Migrate the httpclient:get() method to named arguments so we can
specify optional arguments.
This allows to pass headers as an optional argument as an array.
The () in the method call must be replaced by {}:
local res = httpclient:get{url="http://127.0.0.1:9000/?s=99",
headers= {["X-foo"] = { "salt" }, ["X-bar"] = {"pepper" }}}
This reg-test is heavily inspired by the lua_socket.vtc one.
It replaces the HTTP/1.1 request made manually with a socket object with
an httpclient object.
