我正在尝试登录网站并下载csv文件，登录似乎有效，但csv文件未下载，当我手动执行此操作时，我可以毫无问题地下载该文件。 它不会给出任何错误消息，var_dump输出显示"true"
谁能帮我狐狸这个，谢谢
define( 'LOGINURL', 'http://www.highlite.nl/user/login' );
define( 'LOGINFIELDS', 'Login=xxxxxx&Password=xxxx&LoginButton=LoginButton' );
define( 'DWNLDURL', 'http://www.highlite.nl/silver.download/download/products_v2_0.csv' );
$ckfile = tempnam ("/tmp", "CURLCOOKIE");
$fp = fopen("/tmp/import.csv", "w");
/* STEP 2. visit the login page to authenticate and set the cookie properly */
$ch = curl_init( LOGINURL );
curl_setopt( $ch, CURLOPT_COOKIESESSION, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, LOGINFIELDS );
curl_setopt( $ch, CURLOPT_POST, 1 );
curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec( $ch );
/* STEP 3. request download */
$ch = curl_init();
curl_setopt( $ch, CURLOPT_COOKIEFILE, $ckfile );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_URL,DWNLDURL);
curl_setopt($ch, CURLOPT_FILE, $fp);
//curl_setopt($ch, CURLOPT_URL, $ch);
$result = curl_exec( $ch );
var_dump($result);
尝试将'w+'添加到fopen函数中
将。。
$fp = fopen("/tmp/import.csv", "w+");
成功后，fopen 函数将返回文件指针资源。请注意，我们传入"w+"作为第二个参数，因为"w+"告诉PHP我们要打开文件进行读写。
成功设置文件指针后，我们可以通过CURLOPT_FILE选项将其移交给 cURL，就像您已经在做的事情一样。
//Pass our file handle to cURL.
curl_setopt($ch, CURLOPT_FILE, $fp);
请尝试这个
define( 'LOGINURL', 'http://www.highlite.nl/user/login' );
define( 'LOGINFIELDS', 'Login=xxxxxx&Password=xxxx&LoginButton=LoginButton' );
define( 'DWNLDURL', 'http://www.highlite.nl/silver.download/download/products_v2_0.csv' );
$ckfile = tempnam ("/tmp", "CURLCOOKIE");
$fp = fopen("/tmp/import.csv", "w+"); // Changed w to w+
/* STEP 2. visit the login page to authenticate and set the cookie properly */
$ch = curl_init( LOGINURL );
curl_setopt( $ch, CURLOPT_COOKIESESSION, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, LOGINFIELDS );
curl_setopt( $ch, CURLOPT_POST, 1 );
curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec( $ch );
/* STEP 3. request download */ /*Updated code*/
$ch = curl_init(DWNLDURL);
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_ENCODING, "");
$result = curl_exec( $ch );
curl_close($ch);
fclose($fp);
var_dump($result);
