php使用curl模拟get和post请求

$api_url = 'https://www.xxxxxxx.com/api/';
$token_url = 'get_token';//获取token
$create_url = '/user/save';//创建用户

// get请求一，参数使用数组传递
$params = array(
	        "appid" => $appid,
	        "create_time" => $time,
	        "sign" => $sign
	    );
$getTokenUrl = $api_url . $token_url;
$result = curlGet($getTokenUrl, $params);

// get请求二，地址中拼接参数
$getTokenUrl = $api_url . $token_url . '?appid=' . $appid . '&create_time=' . $time . '&sign=' . $sign;
$result = curlGet($getTokenUrl);

// post请求
$createUserUrl = $api_url . $create_url;
    $header  = array(
	    'token:' . $token,
	    'content-type: application/json'
    );
$data = array(
        "nick" =>"问卷test",
        "crm_status" => 4,
        "tel" => 15232186580
    );
$result = curlPost($createUserUrl, $data, 5, $header, 'json');



function curlPost($url, $post_data = array(), $timeout = 5, $header = "", $data_type = "") {
    $header = empty($header) ? '' : $header;
    //支持json数据数据提交
    if($data_type == 'json'){
        $post_string = json_encode($post_data);
    }elseif($data_type == 'array') {
        $post_string = $post_data;
    }elseif(is_array($post_data)){
        $post_string = http_build_query($post_data, '', '&');
    }
    
    $ch = curl_init();    // 启动一个CURL会话
    curl_setopt($ch, CURLOPT_URL, $url);     // 要访问的地址
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);  // 对认证证书来源的检查   // https请求 不验证证书和hosts
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);  // 从证书中检查SSL加密算法是否存在
    curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // 模拟用户使用的浏览器
    //curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转
    //curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer
    curl_setopt($ch, CURLOPT_POST, true); // 发送一个常规的Post请求
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);     // Post提交的数据包
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);     // 设置超时限制防止死循环
    curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
    //curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     // 获取的信息以文件流的形式返回 
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //模拟的header头
    $result = curl_exec($ch);
 
    curl_close($ch);
    return $result;
}    
function curlGet($url, $params = array(), $header = array())
{

    $opts = array(
        CURLOPT_TIMEOUT        => 30,
        CURLOPT_RETURNTRANSFER => 1,
        CURLOPT_SSL_VERIFYPEER => false,
        CURLOPT_SSL_VERIFYHOST => false,
        CURLOPT_HTTPHEADER     => $header
    );
    
    $opts[CURLOPT_URL] = $url;
    if (!empty($params))
    {
        $opts[CURLOPT_URL] .= '?' . http_build_query($params);
    }

    /* 初始化并执行curl请求 */
    $ch = curl_init();
    // curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt_array($ch, $opts);
    $data  = curl_exec($ch);

    $error = curl_error($ch);

    curl_close($ch);
    if ($error)
    {
        throw new Exception('请求发生错误：' . $error);
    }

    return $data;
}

如有需要，可结合以上代码自行修改成为一个方法
