Question

我正在使用以下代码来抓住挑战

preg_match("/'03AHJ(.*?)'/", $recaptcha_page_response,$captchastring);

在以下文字

var RecaptchaState = {
    challenge : '03AHJ_VuvTTaeouhgwbBXLQxnyRpYagVrS5lfF2N90aSRWHio3pAyqd6lfnHnWb_cveXafWHcgtK5zmhpetpy2NAWxfoDlCXuub3v2GUaA7EZDn0VqA6CheWWiF8yFBM3i7zN0XtKzHKItsxfcArzgmH4ARft-OWzSrOGpAM_oG0hp12cZMgWmV15FwCNCtFuypkxnPhDv8Fagw4YDInvxal8nhxIJEen6M4iBJx4KGCjolyqImbzJ54I7jFZaS9OMlK-Giv3cOq7aHUTGJeG9f9joya4WkXXKsg',
    timeout : 1800,
    lang : 'en',
    server : 'http://www.google.com/recaptcha/api/',
    site : '6LeC3O0SAAAAAC_YcSZKQChES7yidMTP_h-6uTTX',
    error_message : '',
    programming_error : '',

然而它也返回'in array [0]，这样就变成了

$captchastring = "http://www.google.com/recaptcha/api/image?c=$captchastring[0]";

此

http://www.google.com/recaptcha/api/image?c='03AHJ_VutYynsKzGrLzB3czHAOTgfl2jGc-r0S5fVXz9oELZQN-CbgtFqbZO0m-ZyfrcxDxw9NOWVvCZ2hsZqBY-fBNgCzW4Q1zgmLOMxgugVLYLc49GODWISsde0uKz904r-5qDC9VybX6AsmrUfAOnrgCfyKZUmGWkVtG1Zgjy5N-dQjldW_XOeWr94FlxKic-yG_9ca34fJnLZ06ol2FsYq9DeTZqsAYQ'

这显然是错误的，正则表达式会在''之间获得所有内容，但不包括它们在返回的数组中？

Answer 1

preg_match("/(?<=')03AHJ[^']*/", $recaptcha_page_response,$captchastring);

正则表达式获取撇号之间的所有内容但不返回撇号
