Apache BenchでJSONをPHPに投げてテスト

## テスト

PHPでJSONを受け取る処理のテストに困りました。
JSONを簡単に投げる方法知らないのですもの。
ab(Apache Bench)を使うと楽ちんです。

## ab - Apache Bench

### テスト用のJSONファイル

PHPへの投入データです

```json:json.json
{
    "hoge":123456,
    "hege":999
}
```

Apacheの入っているサーバでぶん投げます。
※ ab(ApacheBench)コマンドが入ってるので…
最初に100スレッド投げてますが1スレッドで良いです。

```shell-session
ekaneko@bibian ~/work/json % cat >./kick_ab.sh
#!/bin/sh
ab -n 100 -c 100 -p ./json.json -T "application/json; charset=utf-8" "http://localhost/tam/getJson.php"
[ctrl]+[d]
ekaneko@bibian ~/work/json % sh ./kick_ab.sh

### 受け取り側PHPソース

適当にコピペして書いたので違ってたらごめん

```php:getJson.php
<?php

define('DEBUGOUT', './debug_out.log');

function debugPuts($str)
{
    $buff = sprintf("%s %s\n", date("Y-m-d H:i:s"), $str);
    error_log($buff, 3, DEBUGOUT);
}


$raw = file_get_contents( 'php://input');
// if(isset($HTTP_RAW_POST_DATA))
// {
//     $raw = trim($HTTP_RAW_POST_DATA);
// }
$mess = 'getdata:'.var_export($raw, true);
debugPuts($mess);

$insDataArray =  json_decode($raw, true);
$mess = '[json_decode]'.var_export($insDataArray, true);
debugPuts($mess);

// 成功 失敗返却
// $data = array('some_key' => 'some_value');
$data = array(1,0);

header('Access-Control-Allow-Origin: *');
$callback = isset($_GET['callback']) ? preg_replace('/[^a-z0-9$_]/si', '', $_GET['callback']) : false;
if($callback)
{
    $callback = htmlspecialchars(strip_tags($callback));
    header('Content-Type: application/javascript;charset=utf-8');
    echo $callback.'('.json_encode($data).')';
}
else
{
    // header('Content-Type: text/javascript; charset=utf-8');
    header('Content-Type: application/json;charset=utf-8');
    // $data = array('some_key' => 'some_value');
    echo json_encode($data);
}
```
