php curl可以登录网站，但登录后不显示任何数据
[英]php curl Able to login into site but shows no data after login
问题描述
HI, 
HI，
I am able to login into the site using php and curl. 我可以使用php和curl登录该站点。 but when i try to read the data after logging in it shows string(0) "" if CURLOPT_RETURNTRANSFER enabled and when disabled it shows bool(true). 但是当我登录后尝试读取数据时，如果启用了CURLOPT_RETURNTRANSFER，则显示string（0）“”；而当禁用时，它显示bool（true）。 I dont understand where exactly i am going wrong... 我不明白我到底要去哪里...
any help is really appreciated 任何帮助都非常感谢

Your curl_close calls are broken. 您的curl_close通话中断。 Pass in the curl resource. 传递curl资源。 Eg: 例如：
curl_close($ch);
This is why you should enable and pay attention to warnings. 这就是为什么您应该启用并注意警告的原因。
php > curl_close();
PHP Warning: curl_close() expects exactly 1 parameter, 0 given in php shell code on line 1
This in turn means your cookie jar won't work properly. 反过来，这意味着您的Cookie罐将无法正常运行。

Chances are good that there is a redirect that is happening upon verification of your credentials. 很有可能在验证您的凭据时发生重定向。 You can still use CURLOPT_FOLLOWLOCATION without having to actually print that to screen - is there a reason why you have it commented out? 您仍然可以使用CURLOPT_FOLLOWLOCATION而无需实际将其打印到屏幕上-是否有理由将其注释掉？

should these variables be different? 这些变量应该不同吗？
// v
curl_setopt($ch1, CURLOPT_COOKIEFILE, $cookie_fie_path);
curl_setopt($ch1, CURLOPT_COOKIEJAR, $cookie_file_path);
// ^
It may be that your cookies aren't being stored/retrieved properly. 可能是您的Cookie没有正确存储/检索。
httpRequest Class Example (short form static constructors): httpRequest类示例（简短形式的静态构造函数）：
$loginAttempt = httpRequest::post(
'https://kinray.com/redirector1/weblink.jsp',
'custId=XXXXX&passWord=YYYYY'
)
->ignoreSSL()
->setCookieJar($cookie_file_path)
->retrieveHeader()
->setManualOption(CURLOPT_REFERER, "http://www.google.com")
->splode(); // executes the request
// you can get to the returned value with $loginAttempt->responseRaw,
// or a host of other options, see __get()
$loggedInPage = httpRequest::get('https://kinray.com/weblink2/search/categories.do?scrollType=&code=&alwaysCustomerNumber=023987')
->ignoreSSL()
->setCookieJar($cookie_file_path)
->splode();
you can easily get to the response body by accessing the body property ( $loggedInPage->body , for example) from there. 您可以通过从那里访问body属性（例如$loggedInPage->body ）轻松地到达响应正文。 Let me know if this works for you. 让我知道这是否适合您。
