《PHP學(xué)習(xí)：php實(shí)現(xiàn)模擬登陸方正教務(wù)系統(tǒng)抓取課表》要點(diǎn)：
本文介紹了PHP學(xué)習(xí)：php實(shí)現(xiàn)模擬登陸方正教務(wù)系統(tǒng)抓取課表，希望對(duì)您有用。如果有疑問，可以聯(lián)系我們。
PHP應(yīng)用課程格子和超級(jí)課程表這兩個(gè)應(yīng)用,想必大學(xué)生都很熟悉,使用自己的學(xué)號(hào)和教務(wù)系統(tǒng)的暗碼,就可以將自己的課表導(dǎo)入,隨時(shí)隨地都可以在手機(jī)上查看.
PHP應(yīng)用 其實(shí)稍微了解一點(diǎn)php的話,我們也可以做一個(gè)類似這樣的web 應(yīng)用.
PHP應(yīng)用 1,辦理掉驗(yàn)證碼
PHP應(yīng)用 其實(shí)這是正方的一個(gè)小bug,當(dāng)我們進(jìn)入登陸界面時(shí),瀏覽器會(huì)去哀求服務(wù)器,服務(wù)器會(huì)生成一個(gè)驗(yàn)證碼圖片.如果我們不去哀求這個(gè)圖片,那么正方后臺(tái)也不會(huì)生成相應(yīng)的??????? 驗(yàn)證碼,于是這樣我們就有了可乘之機(jī),讓我高興會(huì)兒~這時(shí),我們?cè)诓惶顚戲?yàn)證碼的情況下,可以很流暢的進(jìn)入.大家可以在自己的電腦上禁止訪問驗(yàn)證碼的地址,然后試試這??????? 是不是真的~當(dāng)然,這只對(duì)正方有效.
PHP應(yīng)用 2,php 的curl 模擬登陸
PHP應(yīng)用 接下來(lái)便是相關(guān)代碼了,相信很多人和我一樣,只喜歡看例子,對(duì)于長(zhǎng)篇大論的講解,轉(zhuǎn)頭就走……不過(guò)這個(gè)習(xí)慣還是不好……廢話不多說(shuō)!
PHP應(yīng)用
//模擬登陸
function curl_request($url,$post='',$cookie='', $returnCookie=0){
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0)');
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
curl_setopt($curl, CURLOPT_REFERER, "這里一定要換成教務(wù)系統(tǒng)登陸的url"); //填寫教務(wù)系統(tǒng)url
if($post) {
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post));
}
if($cookie) {
curl_setopt($curl, CURLOPT_COOKIE, $cookie);
}
curl_setopt($curl, CURLOPT_HEADER, $returnCookie);
curl_setopt($curl, CURLOPT_TIMEOUT, 20);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
if (curl_errno($curl)) {
return curl_error($curl);
}
curl_close($curl);
if($returnCookie){
list($header, $body) = explode("\r\n\r\n", $data, 2);
preg_match_all("/Set\-Cookie:([^;]*);/", $header, $matches);
$info['cookie'] = substr($matches[1][0], 1);
$info['content'] = $body;
return $info;
}else{
return $data;
}
}
PHP應(yīng)用 3,教務(wù)系統(tǒng)登陸頁(yè)面的暗藏字段
PHP應(yīng)用 舉個(gè)栗子
PHP應(yīng)用 這些東西在登陸的時(shí)候也是必要帶上的,順便貼出函數(shù),順便暴漏了博主的學(xué)校……皇家種地大學(xué)(主要是正則表達(dá)式的運(yùn)用)
PHP應(yīng)用
//登陸頁(yè)面的暗藏字段
function getView(){
$url = 'http://jw.hzau.edu.cn/default2.aspx';
$result = curl_request($url);
$pattern = '/<input type="hidden" name="__VIEWSTATE" value="(.*?)" \/>/is';
preg_match_all($pattern, $result, $matches);
$res[0] = $matches[1][0];
return $res[0] ;
}
//返回教室查詢頁(yè)面的暗藏值
private function getViewJs($cookie,$xh){
$url = "http://jw.hzau.edu.cn/xxjsjy.aspx?xh={$xh}";
$result = curl_request($url,'',$cookie);
$pattern = '/<input type="hidden" name="__VIEWSTATE" value="(.*?)" \/>/is';
preg_match_all($pattern, $result, $matches);
$res[0] = $matches[1][0];
return $res[0] ;
}
PHP應(yīng)用 4,cookie 的獲取
PHP應(yīng)用
function login($xh,$pwd){
$url = 'http://jw.hzau.edu.cn/default2.aspx';
$post['__VIEWSTATE'] = $this->getView();
$post['txtUserName'] = $xh; //填寫學(xué)號(hào)
$post['TextBox2'] = $pwd; //填寫暗碼
$post['txtSecretCode'] = '';
$post['lbLanguage'] = '';
$post['hidPdrs'] = '';
$post['hidsc'] = '';
$post['RadioButtonList1'] = iconv('utf-8', 'gb2312', '學(xué)生');
$post['Button1'] = iconv('utf-8', 'gb2312', '登錄');
$result = curl_request($url,$post,'', 1);
return $result['cookie'];
}
PHP應(yīng)用 5,讓我們來(lái)試試查課表的功能,格式有點(diǎn)亂額,大家湊合著看,我把課表轉(zhuǎn)成了一個(gè)二維關(guān)聯(lián)數(shù)組
PHP應(yīng)用
//返回課表字符串
private function classresult($xh,$pwd){
date_default_timezone_set("PRC"); //時(shí)區(qū)設(shè)置
$classList = "";//聲明課表變量
$cookie = $this->login($xh,$pwd);
$view = $this->getViewJs($cookie,$xh);//驗(yàn)證暗碼是否正確
//如果暗碼正確
if (!empty($view)) {
$url = "http://jw.hzau.edu.cn/xskbcx.aspx?xh={$xh}";
$result = curl_request($url,'',$cookie); //保存的cookies
preg_match_all('/<table id="Table1"[\w\W]*?>([\w\W]*?)<\/table>/',$result,$out);
$table = $out[0][0]; //獲取整個(gè)課表
preg_match_all('/<td [\w\W]*?>([\w\W]*?)<\/td>/',$table,$out);
$td = $out[1];
$length = count($td);
//獲得課程列表
for ($i=0; $i < $length; $i++) {
$td[$i] = str_replace("<br>", "", $td[$i]);
$reg = "/{(.*)}/";
if (!preg_match_all($reg, $td[$i], $matches)) {
unset($td[$i]);
}
}
$td = array_values($td); //將課程列表數(shù)組重新索引
$tdLength = count($td);
for ($i=0; $i < $tdLength; $i++) {
$td[$i] = iconv('GB2312','UTF-8',$td[$i]);
}
//將課表轉(zhuǎn)換成數(shù)組形式
function converttoTable($table){
$list = array(
'sun' => array(
'1,2' => '',
'3,4' => '',
'5,6' => '',
'7,8' => '',
'9,10' => ''
),
'mon' => array(
'1,2' => '',
'3,4' => '',
'5,6' => '',
'7,8' => '',
'9,10' => ''
),
'tues' => array(
'1,2' => '',
'3,4' => '',
'5,6' => '',
'7,8' => '',
'9,10' => ''
),
'wed' => array(
'1,2' => '',
'3,4' => '',
'5,6' => '',
'7,8' => '',
'9,10' => ''
),
'thur' => array(
'1,2' => '',
'3,4' => '',
'5,6' => '',
'7,8' => '',
'9,10' => ''
),
'fri' => array(
'1,2' => '',
'3,4' => '',
'5,6' => '',
'7,8' => '',
'9,10' => ''
),
'sat' => array(
'1,2' => '',
'3,4' => '',
'5,6' => '',
'7,8' => '',
'9,10' => ''
)
);
$week = array("sun"=>"周日","mon"=>"周一","tues"=>"周二","wed"=>"周三","thur"=>"周四","fri"=>"周五","sat"=>"周六");
$order = array('1,2','3,4','5,6','7,8','9,10');
foreach ($table as $key => $value) {
$class = $value;
foreach ($week as $key => $weekDay) {
$pos = strpos($class,$weekDay);
// echo $pos;
if ($pos) {
$weekArrayDay = $key; //獲取list數(shù)組中的第一維key
foreach ($order as $key => $orderClass) {
$pos = strpos($class,$orderClass);
if ($pos) {
$weekArrayOrder = $orderClass; //獲取該課程是第幾節(jié)
break;
}
}
break;
}
}
$list[$weekArrayDay][$weekArrayOrder] = $class;
}
return $list;
}
//調(diào)用函數(shù)
return converttoTable($td);
}else{
return 0;
}
}
PHP應(yīng)用 6,再試試查詢空教室的功能
PHP應(yīng)用
//空教室查詢結(jié)果
public function roomresult(){
$xh = ""; //設(shè)置學(xué)號(hào)
$pwd = ""; //學(xué)號(hào)對(duì)應(yīng)的暗碼
$cookie = $this->login($xh,$pwd);
$url = "http://jw.hzau.edu.cn/xs_main.aspx?xh={$xh}";
$result = curl_request($url,'',$cookie); //保存的cookies
$url="http://jw.hzau.edu.cn/xxjsjy.aspx?xh={$xh}";
$post['Button2'] = iconv('utf-8', 'gb2312', '空教室查詢');
$post['__EVENTARGUMENT']='';
$post['__EVENTTARGET']='';
$post['__VIEWSTATE'] = $this->getViewJs($cookie,$xh);
$post['ddlDsz'] = iconv('utf-8', 'gb2312', '單');
$post['ddlSyXn'] = '2014-2015'; //學(xué)年
$post['ddlSyxq'] = '1';
$post['jslb'] = '';
$post['xiaoq'] = '';
$post['kssj']=$_GET['start']; //提交的開始查詢時(shí)間
$post['sjd']=$_GET['class'];//提交的課程節(jié)次
$post['xn']='2014-2015';//所在學(xué)年
$post['xq']='2';//所在學(xué)期
$post['xqj']='6';//當(dāng)天星期幾
$post['dpDataGrid1:txtPageSize']=90;//每頁(yè)顯示條數(shù)
$result = curl_request($url,$post,$cookie,0);
preg_match_all('/<span[^>]+>[^>]+span>/',$result,$out);
$tip = iconv('gb2312', 'utf-8', $out[0][3]);//獲取頁(yè)面前部的提示內(nèi)容
preg_match_all('/<table[\w\W]*?>([\w\W]*?)<\/table>/',$result,$out);
$table = iconv('gb2312', 'utf-8', $out[0][0]); //獲取查詢列表
$this->load->view("classroom",array('tip'=>$tip,'table'=>$table));
}
PHP應(yīng)用 總結(jié)起來(lái)就是這些了,每個(gè)學(xué)校的教務(wù)系統(tǒng)都不盡相同,這時(shí)我們可以借助火狐瀏覽器的 firebug 抓包,看看到底提交了哪些東西.
PHP應(yīng)用以上所述便是本文的全部?jī)?nèi)容了,希望大家能夠喜歡.
