php curl 提交 总结

1、post https提交 方法 

function curl_post2($url='', $postdata='', $options=array()){
    $ch = curl_init($url);
     
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
    curl_setopt($ch, CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']);
     
     
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
    curl_setopt($ch, CURLOPT_TIMEOUT, 20);
    if (!empty($options)){
        curl_setopt_array($ch, $options);
    }
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

2、普通post提交 

//通过curl模拟post的请求；
function SendDataByCurl($url,$data=array()){
    //对空格进行转义
    $url = str_replace(' ','+',$url);
    $ch = curl_init();
    //设置选项，包括URL
    curl_setopt($ch, CURLOPT_URL, "$url");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch,CURLOPT_TIMEOUT,3);  //定义超时3秒钟 
     // POST数据
    curl_setopt($ch, CURLOPT_POST, 1);
    // 把post的变量加上
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));    //所需传的数组用http_bulid_query()函数处理一下，就ok了
     
    //执行并获取url地址的内容
    $output = curl_exec($ch);
    $errorCode = curl_errno($ch);
    //释放curl句柄
    curl_close($ch);
    if(0 !== $errorCode) {
        return false;
    }
    return $output;
 
}
 
function curl_post($url='', $postdata='', $options=array()){
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);
    if (!empty($options)){
        curl_setopt_array($ch, $options);
    }
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

3、curl get提交

function curl_get($url='', $options=array()){
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);
    if (!empty($options)){
        curl_setopt_array($ch, $options);
    }
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

参考：

function vpost($url,$data,$cookie){ // 模拟提交数据函数
    $curl = curl_init(); // 启动一个CURL会话
    curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 对认证证书来源的检查
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1); // 从证书中检查SSL加密算法是否存在
    curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // 模拟用户使用的浏览器
    curl_setopt($curl, CURLOPT_COOKIE, $cookie);
    curl_setopt($curl, CURLOPT_REFERER,'https://www.baidu.com');// 设置Referer
    curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Post提交的数据包
    curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循环
    curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回
    $tmpInfo = curl_exec($curl); // 执行操作
    if (curl_errno($curl)) {
       echo 'Errno'.curl_error($curl);//捕抓异常
    }
    curl_close($curl); // 关闭CURL会话
    return $tmpInfo; // 返回数据
}
