curl爬教务系统的数据
你好各位又来请教大家了,我现在又遇到这样的情况
代码是这样子的


header ( "content-Type: text/html; charset=utf-8" );
 require_once 'search.php';
// 第一步:提交数据,生成cookie,将cookie保存在临时目录下
$cookiejar = realpath ( 'cookie.txt' );
$id=$_GET['id'];
$password=$_GET['password'];
$year=$_GET['year'];
$term=$_GET['term'];

";
//echo   $matches[1][0];
//echo ''.$data.'';
echo search3($id,$year, $term,$ch,$matches[1][0]);
?>


function search3($id,$year, $term, $ch,$value){
//$data=file_get_contents("d://value.txt");
curl_setopt ( $ch, CURLOPT_PROXY, 'jackdowosn.gnway.net:81');
$curlPost = "xh=K061141026&__VIEWSTATE=$value&Button2=按学年学期查询&ddlKCLX=必修&xn=2012-2013&xq=1";
$curlPost = iconv("UTF-8", "GBK", $curlPost);

curl_setopt ( $ch, CURLOPT_REFERER, "http://211.67.32.51/xscj.aspx?xh=K061141026" );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $curlPost );
curl_setopt ( $ch, CURLOPT_COOKIEFILE, $cookiejar ); // 要回传cookie
$data = curl_exec ( $ch );
curl_close ( $ch );
$data = mb_convert_encoding ( $data, "utf-8", "GBK" );
/*preg_match_all ( '/\\s*\(.*?)\\s*\ (.*?)\/is', $data, $matches );
foreach ( $matches [1] as $key => $val )
$nav =$nav ."\n". $val . "---" . $matches [2] [$key];*/
return $data;
}


以上程序执行到search3时出现了,其他的都可正常返回数据。我问过一个前辈,他的回答是“我也不清楚喔。我有印象我们做正方系统遇到这种问题有可能是参数传错了,有可能是编码错了,也有可能没设置Referer这个参数”。请大家帮我看下问题出在哪里,有兴趣的可以帮我调试下,代理服务器都是真实可用的。下面是几个post参数和头信息

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
