From fb133d0a8c99a26b0f26bde21bf88e71b6235cba Mon Sep 17 00:00:00 2001 From: Lastres Date: Mon, 21 Jan 2013 16:55:35 +0000 Subject: [PATCH 01/49] Totally restructure the lhttpc client. lhttpc_client is now a gen_server. Now it supports conections without using a pool. It is possible to define clients and use them to establish connections. All the code from this commit was done by me and Diana Corbacho. --- include/lhttpc_types.hrl | 2 +- src/lhttpc.erl | 139 ++++--- src/lhttpc_client.erl | 847 ++++++++++++++++++++++++--------------- src/lhttpc_manager.erl | 19 +- 4 files changed, 615 insertions(+), 392 deletions(-) diff --git a/include/lhttpc_types.hrl b/include/lhttpc_types.hrl index 64bc9323..3ae9e251 100644 --- a/include/lhttpc_types.hrl +++ b/include/lhttpc_types.hrl @@ -86,7 +86,7 @@ -type window_size() :: non_neg_integer() | 'infinity'. --type upload_state() :: {pid(), window_size()}. +-type upload_state() :: {partial_upload, pid()}. -type body() :: binary() | 'undefined' | % HEAD request. diff --git a/src/lhttpc.erl b/src/lhttpc.erl index 8b3dc308..564a01c2 100644 --- a/src/lhttpc.erl +++ b/src/lhttpc.erl @@ -26,7 +26,9 @@ %%------------------------------------------------------------------------------ %%% @author Oscar Hellström -%%% @doc Main interface to the lightweight http client. +%%% @author Diana Parra Corbacho +%%% @author Ramon Lastres Guerrero +%%% @doc Main interface to the lightweight http client %%% See {@link request/4}, {@link request/5} and {@link request/6} functions. %%% @end %%------------------------------------------------------------------------------ @@ -35,8 +37,11 @@ -export([start/0, stop/0, start/2, stop/1, request/4, request/5, request/6, request/9, + request_client/5, request_client/6, request_client/7, add_pool/1, add_pool/2, add_pool/3, delete_pool/1, + connect_client/2, + disconnect_client/1, send_body_part/2, send_body_part/3, send_trailers/2, send_trailers/3, get_body_part/1, get_body_part/2 @@ -161,6 +166,70 @@ delete_pool(PoolName) when is_atom(PoolName) -> {error, Reason} -> {error, Reason} end. +%%------------------------------------------------------------------------------ +%% @doc Starts a Client. +%% @end +%%------------------------------------------------------------------------------ +%-spec connect( ,options()) -> {ok,Pid} | ignore | {error,Error}. +% WHICH TIMEOUT TO USE? +connect_client(Destination, Options) -> + %Gs_Options = ?? + lhttpc_client:start({Destination, Options}, []). + +%%------------------------------------------------------------------------------ +%% @doc Stops a Client. +%% @end +%%------------------------------------------------------------------------------ +-spec disconnect_client(pid()) -> ok. +disconnect_client(Client) -> + lhttpc_client:stop(Client). + + +%REQUESTS USING THE CLIENT +-spec request_client(pid(), string(), method(), headers(), pos_timeout()) -> result(). +request_client(Client, PathOrUrl, Method, Hdrs, Timeout) -> + request_client(Client, PathOrUrl, Method, Hdrs, [], Timeout, []). + +-spec request_client(pid(), string(), method(), headers(), iodata(), pos_timeout()) -> result(). +request_client(Client, PathOrUrl, Method, Hdrs, Body, Timeout) -> + request_client(Client, PathOrUrl, Method, Hdrs, Body, Timeout, []). + + +-spec request_client(pid(), string(), method(), headers(), iodata(), + pos_timeout(), options()) -> result(). +request_client(Client, PathOrUrl, Method, Hdrs, Body, Timeout, Options) -> + {FinalPath, FinalHeaders} = + case lhttpc_lib:parse_url(PathOrUrl) of + #lhttpc_url{ %its an URL + host = _Host, + port = _Port, + path = Path, + is_ssl = _Ssl, + user = User, + password = Passwd + } -> % @TODO: check that the host is the right one. + Headers = case User of + "" -> + Hdrs; + _ -> + Auth = "Basic " ++ binary_to_list(base64:encode(User ++ ":" ++ Passwd)), + lists:keystore("Authorization", 1, Hdrs, {"Authorization", Auth}) + end, + {Path, Headers}; + %request_client(Client, Path, Method, Headers, Body, Timeout, Options); + _ -> % its a path + %request_client(Client, PathOrUrl, Method, Hdrs, Body, Timeout, Options) + {PathOrUrl} + end, + verify_options(Options), + try + Reply = lhttpc_client:request(Client, FinalPath, Method, FinalHeaders, Body, Options, Timeout), + Reply + catch + exit:{timeout, _} -> + {error, timeout} + end. + %%------------------------------------------------------------------------------ %% @spec (URL, Method, Hdrs, Timeout) -> Result %% URL = string() @@ -427,18 +496,15 @@ request(URL, Method, Hdrs, Body, Timeout, Options) -> headers(), iodata(), pos_timeout(), options()) -> result(). request(Host, Port, Ssl, Path, Method, Hdrs, Body, Timeout, Options) -> verify_options(Options), - Args = [self(), Host, Port, Ssl, Path, Method, Hdrs, Body, Options], - Pid = spawn_link(lhttpc_client, request, Args), - receive - {response, Pid, R} -> - R; - {'EXIT', Pid, Reason} -> - % This could happen if the process we're running in traps exits - % and the client process exits due to some exit signal being - % sent to it.

- * Erlang/OTP R13-B or newer
-   * Application compiler to build, kernel, stdlib and ssl to run
-
-Building: 
-For versions > 1.2.5, lhttpc is built using rebar. Take a look at http://bitbucket.org/basho/rebar/wiki/Home for more information. There is still a Makefile with some of the old make targets, such as all, doc, test etc. for those who prefer that. The makefile will however just call rebar.

-                       kepp a HTTP/1.1 connection open. Changing this value
-                       in runtime has no effect, this can however be done
-                       through lhttpc_manager:update_connection_timeout/1.

+# LHTTPC - Lightweight HTTP Client #
+
+Copyright (c) 2009-2013 Erlang Solutions Ltd.
+
+## Starting
+
+Download the sources or clone the git repository. Then you can build with:
+
+```
+make all
+```
+
+which will generate .beam files and documentation. To start the lhttpc OTP application, you first need to start the applications it depends on:
+
+```
+$ erl -pa ebin
+1> application:start(crypto),
+1> application:start(public_key),
+1> application:start(ssl),
+1> lhttpc:start().
+ok
+```
+
+## Usage
+Lhttpc allows the user to send requests by always spawning a process for each of them, or reusing a single client process for several requests. It also allows the usage of pools of connections in order to keep connections alive and reuse them.
+
+### Send a simple request
+A single request without using a client process, will just spawn a process, do the request, and then stop the process.
+
+```erlang
+Method = get,
+URL = "http://www.erlang-solutions.com",
+Headers = [],
+Timeout = 100,
+{ok,{{StatusCode, Status}, Headers, Body}} = lhttpc:request(URL, Method, Headers, Timeout).
+```
+Using the function `request/9` it is also possible to specify the target server using `Host`, `Port` and `Ssl` and a relative `Path`. All the available options are listed in the documentation.
+
+### Reuse a client process
+
+It is possible to first connect a client process to the target server, and then do a requests specifing just the relative Path:
+
+```erlang
+{ok, Client} = lhttpc:connect_client("http://erlang-solutions.com", []),
+{ok,{{StatusCode, Status}, Headers, Body}} = lhttpc:request_client(Client, "/", get, [], 100).
+```
+
+And then reuse the same client to do more requests to the same server.
+
+### Use connection pools
+
+Lhttpc supports pools of connections. They keep the connections to the different servers independently of the client processes. Therefore, if we do a requests specifing a pool, the client process will try to retrieve the connection from the pool if there is one, use it, and then return it to the pool before stopping. This makes it possible to share connections between different client processes and keep connections alive.
+
+```erlang
+lhttpc:add_pool(my_pool),
+lhttpc:request("http://www.erlang-solutions.com", get, [], [], 100, [{pool_options, [{pool, my_pool}]}]).
+```
+
+The `lhttpc_manager` module provides functions to retrive information about the pools:
+
+```
+>lhttpc_manager:connection_count(my_pool).
+0
+>lhttpc:request("http://www.erlang-solutions.com", get, [], [], 100, [{pool_options, [{pool, my_pool}]}]).
+>lhttpc_manager:connection_count(my_pool).
+1
+>
+>lhttpc_manager:list_pools().
+[{my_pool,[{max_pool_size,50},{timeout,300000}]}]
+>lhttpc_manager:update_connection_timeout(my_pool, 1000).
+ok
+>lhttpc_manager:list_pools().
+[{my_pool,[{max_pool_size,50},{timeout,1000}]}]
+```
+
+### Automatic cookie handling
+Lhttpc supports basic cookie handling. If you want the client process to automatically handle the cookies, use the option `{use_cookies, true}`.
+
+### Transfering the body by chunks
+
+If you want to send the body of the request by chunks, you can specify the `{partial_upload, true}` option. Then use the `send_body_part/2` and `send_body_part/3` functions to send the body parts.
