前言

目前的幾個項目，業(yè)務(wù)方基本都使用POST方式請求接口，本機磁盤會保留一份請求的原始參數(shù)用于請求分析和問題排查使用，一般有問題，也會基于seqid(請求唯一id)撈到日志，copy參數(shù)模擬請求看是否復(fù)現(xiàn)，但一直有個比較蛋疼的問題，PHP的$_POST，$_GET，$_REQUEST這些獲取參數(shù)的方法獲取到的數(shù)據(jù)都是經(jīng)過編碼后的，到時copy后可能無法直接使用，最近有同學(xué)吐槽，決定還是解決一下。

網(wǎng)上搜索很多解決方式，有通過file_get_contents，php input和自定義的一些方法，試了下都不大靠譜，要么根本不解決問題，要么太復(fù)雜不夠靈活，突然想到了$_SERVERG和$_GLOBALS打印了一下：

$_SERVER['REQUEST_URI']：請求地址，GET請求會同時帶上url及地址內(nèi)的參數(shù)
$_SERVER['QUERY_STRING']：請求參數(shù)，但只限于GET方式請求，POST無法獲取到
$_GLOBALS['_POST']： POST請求參數(shù)
$_GLOBALS['_GET']： GET請求參數(shù)

以上獲取到的參數(shù)都為未編碼的原始參數(shù)信息。

結(jié)語

真是踏破鐵鞋無覓處。。合理使用PHP服務(wù)器和全局變量，很多問題其實沒有那么麻煩，拖這么久處理，還想著在nginx階段做處理，也是個大大的無語。文章來源地址http://www.zghlxwxcb.cn/news/detail-437440.html
