githubの中の人が書いた、node.js上で動くHTTP対話コンソールアプリ「http-console」をGoで書いてみた。
mattn知ってる人なら、だいたい名前が想像出来るかな...
そう。

http-gonsole

かっこ悪い？しるか

mattn's http-gonsole at master - GitHub

peak HTTP like a local. (the simple, intuitive HTTP console, golang version)

http://github.com/mattn/http-gonsole

使い方はhttp-consoleと同じにしてあります。node.js版も試してみたんですが、いかんせんインストール面倒くさい(コンパイル重い)し、http-consoleくらいの機能の割にはnode.jsは規模が大きすぎる。
最近go言語にハマってるってところもあったので書いてみました。
インストールにはreadline-goが必要です。
あと、コンテンツがJSONだった場合での色付き表示はサポートしていませんが、フツーに便利です。

接続元の情報でCookie作ってるかもしれないので、一応隠しとく。
Cookieにも対応してます。
あと、あれだな。「POST!」コマンドあたりでPOSTデータをエディタで編集出来る機能が欲しいな。

まぁ、まだ途中ですが...

/lang/lua/webservice-simplua

そこの君！名前がダサイとか言わない！
これを使うとflickr_echo.plのサンプルが local ws = require('webservice.simplua')

local api = ws.new({
    base_url = 'http://api.flickr.com/services/rest',
    params = {
        api_key = 'your_api_key'
    }
})

local ret  = api.get({
    method = 'flickr.test.echo',
    name = 'value'
})

local dom = ret.parse_xml()
print(dom:select("name")[1]:text()) -- "value"
こんな感じに書ける様になります。
まだ、getメソッドの第2引数でpathを指定出来る所までは出来てません。またもちろんcacheも出来てません。
誰かやってください。

rubyのmongrelやthinなんかに変わるhttpdでUnicornとやらがあるのを知った。
ひとまずベンチ取ってみた。rubyでやる専用なのでなにかアプリを書かないと動かないのかな？とりあえずsinatraアプリ書いた。

unicorn-test.rb
require 'rubygems'
require 'sinatra'
set :public, File.dirname(__FILE__)
config.ru
require 'unicorn-test'
run Sinatra::Application
で、unicorn実行。ベンチは
# ab -n 1000 -c 10 -k http://localhost:8080/helloworld.html 2>&1 | tee unicorn.log
で確認した。

unicornの結果

えっ？そういう調査でしたっけ...
