CURL PHP自动登录

Question

我正在尝试制作一个通过CURL进行登录的应用程序，但是我无法使该应用程序正常工作，并且在登录后保存了cookie。 显然我可以保存cookie，但是可以使用它。 我不知道我是否在登录代码或使用保存的cookie的方式上做错了。 如果我在登录后通过Chrome手动获取Cookie，则此应用程序已经可以使用。 我认为它在登录此页面后会生成一个主要cookie： https : //www.comprasnet.gov.br/seguro/loginPortalFornecedor.asp ，它将重定向到此https://www.comprasnet.gov.br/intro .htm ，生成第一个cookie。 在我点击此菜单的菜单后： https : //www.comprasnet.gov.br/pregao/fornec/Acompanhar.asp ，它将生成工作所需的两个cookie。

我尝试登录的代码：

<?php
$cookieold = __DIR__.DIRECTORY_SEPARATOR.'cookieJar.txt';
$cookieactive = __DIR__.DIRECTORY_SEPARATOR.'cookieactive.txt';
$ch = curl_init();
$url = "https://www.comprasnet.gov.br/seguro/loginPortalFornecedor.asp";
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0');
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "perfil=Fornecedor&txtLogin=seulogin&txtSenha=suasenha&ambiente=Produção");
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieold);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

$output = curl_exec($ch);

// Define uma nova URL para ser chamada (após o login)
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0');
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieold);
curl_setopt($ch, CURLOPT_URL, 'https://www.comprasnet.gov.br/intro.htm');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// Executa a segunda requisição
$content = curl_exec ($ch);

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0');
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieold);
curl_setopt($ch, CURLOPT_URL, 'https://www.comprasnet.gov.br/pregao/fornec/Acompanhar.asp');
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieactive);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// Executa a terceira requisição
$content2 = curl_exec ($ch);

if ($output === FALSE) {               // verifica erros no curl
   echo "cURL Error: " . curl_error($ch);
}

curl_close($ch);
//echo $content2;
?>

我已经与Cookie一起使用的代码已手动获取：

// iniciar sessao
$ch = curl_init();

// opcoes
curl_setopt($ch, CURLOPT_URL, "https://www.comprasnet.gov.br/pregao/fornec/Acompanhar.asp");
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0');
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIE, 'ASPSESSIONIDQGAADDTC=DDLGMJABKGCABIKENDGOBLJJ;ASPSESSIONIDQGCADASC=LFFGLJABPEAKKIOLNLLCOFIC');
//executar sessao
$output = curl_exec($ch);
if ($output === FALSE) {               // verifica erros no curl
   echo "cURL Error: " . curl_error($ch);
}
$output = strtr($output, $conversao); // função de conversão acentuado/não acentuado
//fechar sessao
curl_close($ch);

任何帮助将不胜感激。 我不是程序员，只是一个好奇的家伙，试图使我的工作更轻松。 此应用程序仅使ID供个人使用。

我的建议是在每个输出行之后执行curl_close / curl_init 。 您正在继承上一个curl会话中的设置，例如curl_setopt($ch, CURLOPT_COOKIESESSION, true)和CURLOPT_POSTFIELDS

所以

$output = curl_exec($ch);
curl_close($ch);
$ch = curl_init();

$content = curl_exec($ch);
curl_close($ch);
$ch = curl_init();
