Question

我需要使用CURL显示来自网址的图片。但是在运行此代码后，我只能获得文本数据。没有显示图像？$ one包含验证码图像，我希望用户通过查看image.plz帮助来填充验证码...

curl_setopt( $ch, CURLOPT_USERAGENT,$usergaent );
curl_setopt( $ch, CURLOPT_URL, 'http://sitproject.com/verification.asp?source=login' );
curl_setopt ($ch, CURLOPT_HTTPHEADER, $httpheader);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookie );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch,CURLOPT_REFERER,"http://site2sms.com/login.asp");
$one = curl_exec( $ch );
echo $one;


while debugging $one contains this only no binary image data:

Answer 1

您需要第二个请求，请求查看响应的验证码图片位于：

security/captcha.asp

我会说有一个验证码，他们可能不希望这样的机器人试图使用该服务，所以你需要验证你没有违反任何条款。

Answer 2

你的情况

<?php 
$url = "https://api.github.com/users/softvar"; //enter url to extract from
$send_curl = curl_init($url);
curl_setopt($send_curl, CURLOPT_URL, $url);

curl_setopt($send_curl, CURLOPT_HEADER, false);
curl_setopt($send_curl, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($send_curl, CURLOPT_USERAGENT,'softvar'); // your useragent name
curl_setopt($send_curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($send_curl, CURLOPT_HTTPHEADER,array('Accept: application/json', "Content-type: application/json"));
curl_setopt($send_curl, CURLOPT_FAILONERROR, FALSE);
curl_setopt($send_curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($send_curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($send_curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$json_response = curl_exec($send_curl);
echo $json_response; // response in JSON
$response = json_decode($json_response, true);
echo '</br></br>';

$img =  $response['avatar_url']; // instead of 'avatar_url' enter the element name which contains the image url

//while debugging $one contains this only no binary image data:
?>

这是一个完全有效的例子。试试吧。

这就是你获取东西的方式。作为回应，您将根据CURLOPT_HTTPHEADER获取数据。在这里，我使用了JSON。

然后提取你想要的image_url并放在你想要的任何地方。
