PHP按图搜索谷歌cURL返回302移动

我正在尝试获取一个简单的字符串,其中包含我用逐个图像搜索的图像的描述.所以我设置了search_by_google.php页面:

    ]+>([^<]+)/', $searched, $matches);
        return (count($matches) > 1 ? $matches[1] : false);
    }
 }
  ?>

我已经改变了所有卷曲选项但是如果我去http://www.mysite.altervista.org/search_by_google.php?url=http://www.mysite.org/asdasd.jpg&raw=false

它让我说302 Moved

我改变了我的代码

    curl_setopt ($ch, CURLOPT_HEADER, TRUE);

在第二个curl_init()中,现在它给了我这条消息:

我改变了我的代码,如Sabuj Hassan所说,现在的日志是:

可能会发生以下情况:在您的服务器上为您的卷曲阻止了重定向.所以我建议你手动处理重定向.像这个:

首先你的卷曲功能.如果您愿意,可以添加其他卷曲选项:

function curl($url, $user_agent, $retry=0){
    if($retry > 5){
        print "Maximum 5 retries are done, skipping!\n";
        return "in loop!";
    }

    $ch = curl_init();
    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent);
    curl_setopt ($ch, CURLOPT_HEADER, TRUE);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt ($ch, CURLOPT_REFERER, 'http://www.google.com/');
    curl_setopt ($ch, CURLOPT_COOKIEFILE,"./cookie.txt");
    curl_setopt ($ch, CURLOPT_COOKIEJAR,"./cookie.txt");
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $result = curl_exec($ch);
    curl_close($ch);

    // handling the follow redirect
    if(preg_match("|Location: (https?://\S+)|", $result, $m)){
        print "Manually doing follow redirect!\n$m[1]\n";
        return curl($m[1], $user_agent, $retry + 1);
    }

    // add another condition here if the location is like Location: /home/products/index.php

    return $result;
}

这是应该如何调用:

$response = curl("http://www.google.com/", "Mozilla 5.0");
print "$response\n";

我正在解析Location:标题中的以下链接.可能会发生链接未启动的http://情况.那个案例在那里添加另一个条件.

问题可能出在CURLOPT_FOLLOWLOCATION，如果在php.ini中启用了safe_mode或open_basedir，则该URL不可用

试试这个答案：http : //au.php.net/manual/ro/function.curl-setopt.php#71313

只需用注释中提供的curl_redir_exec（）替换curl_exec（）即可。
