curl 使用时，设置代理问题！

Question

先上代码

 public static function curl_get_https($url){
        echo $url;
        $curl = curl_init(); // 启动一个CURL会话
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_HEADER, 0);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 跳过证书检查
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);  // 从证书中检查SSL加密算法是否存在

        curl_setopt($curl, CURLOPT_RETURNTRANSFER,1);
        curl_setopt($curl,CURLOPT_PROXY,'123.163.160.171');
        curl_setopt($curl,CURLOPT_PROXYPORT,'8787');
        curl_setopt ($curl, CURLOPT_TIMEOUT, 20);

        $tmpInfo = curl_exec($curl);     //返回api的json对象

        curl_close($curl);
        return $tmpInfo;    //返回json对象
    }

执行时报错信息

Proxy CONNECT aborted due to timeout

Answer 1

您这是本地测试吗？如果是，请尝试把代理地址改为127.0.0.1

Answer 2

代理服务器连接不上

Answer 3

试用下这段代码

$proxy = "80.25.198.25";
$proxyport = "8080";
$ch = curl_init("http://sfbay.craigslist.org/");

 

curl_setopt($ch, curlOPT_RETURNTRANSFER,1);
curl_setopt($ch,curlOPT_proxy,$proxy);
curl_setopt($ch,curlOPT_proxyPORT,$proxyport);
curl_setopt ($ch, CURLOPT_TIMEOUT, 120);

 

$result = curl_exec($ch);
echo $result;

curl_close($ch);

Answer 4

你这错误提示是代理服务器连接超时。
建议先用curl命令行工具测试一下，确定代理可用并支持HTTPS后再移植到php代码，如：
curl -x 123.163.160.171:8787 https://www.baidu.com
