从curl结果中提取图像

-1

我需要使用CURL来显示来自url的图像。但运行此代码后，我只能获取文本数据。没有图像显示？在$一个含有验证码图像，我希望用户通过看image.plz帮助填写验证码...从curl结果中提取图像

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:

您是否已经在HTML响应中读取了消息...？ – CBroe

你需要第二个请求，请求验证码图像，从看着响应，是：

security/captcha.asp

我会说因为有验证码，他们可能不希望机器人像这样试图使用该服务，所以你需要确认你是不是违反任何条款。

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:

这是一个完全工作的例子。尝试一下。

这就是你如何取东西的方式。作为回应，您将根据您的CURLOPT_HTTPHEADER获取数据。在这里我使用了JSON。

然后提取你想要的image_url并放到任何你想要的位置。

header（“Content-Type：image/bmp”）; header（“Content-Disposition：inline; filename = captcha.bmp”）; echo $ one; –

我必须转移这段代码来分离php，否则它将无法正常工作。因为页眉被更改为image/bmp。 –

我没有得到你。请清楚解释你的问题。 – softvar
