摘要：操作方式方式去除跨域脚本攻击中文转码判断参数是否为空判断是否为数组用来处理不是数组的情况用来处理数组用来处理数组返回微信获取授权第一步取得第二步根据全局和查询用户信息给微信用户发送文字消息导出表格兑换列表导出表格是否下载表格第一列

1.curl操作

POST方式

public static function httpPost($url, $param = "")
{
    $ch1 = curl_init();
    if (version_compare(PHP_VERSION, "5.5.0", ">")) {
        curl_setopt($ch1, CURLOPT_SAFE_UPLOAD, false);
    }

    curl_setopt($ch1, CURLOPT_URL, $url);
    curl_setopt($ch1, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch1, CURLOPT_SSL_VERIFYHOST, false);
    if (!empty($param)) {
        curl_setopt($ch1, CURLOPT_POST, 1);
        curl_setopt($ch1, CURLOPT_POSTFIELDS, $param);
    }
    curl_setopt($ch1, CURLOPT_RETURNTRANSFER, 1);
    $result = curl_exec($ch1);
    curl_close($ch1);
    return $result;
}

GET方式

public static function httpGet($url)
{
    $oCurl = curl_init();
    if (stripos($url, "https://") !== false) {
        curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, false);
    }
    curl_setopt($oCurl, CURLOPT_URL, $url);
    curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1);
    $sContent = curl_exec($oCurl);
    $aStatus  = curl_getinfo($oCurl);
    curl_close($oCurl);
    if (intval($aStatus["http_code"]) == 200) {
        return $sContent;
    } else {
        return false;
    }
}

2.去除跨域脚本攻击

public static function removeXSS($val)
{
    $val    = preg_replace("/([x00-x08,x0b-x0c,x0e-x19])/", "", $val);
    $search = "abcdefghijklmnopqrstuvwxyz";
    $search .= "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    $search .= "1234567890!@#$%^&*()";
    $search .= "~`";:?+/={}[]-_|"";
    for ($i = 0; $i < strlen($search); $i++) {
        $val = preg_replace("/(&#[xX]0{0,8}" . dechex(ord($search[$i])) . ";?)/i", $search[$i], $val);
        $val = preg_replace("/(�{0,8}" . ord($search[$i]) . ";?)/", $search[$i], $val);
    }

    $ra1 = array("javascript", "vbscript", "expression", "applet", "meta", "xml", "blink", "link", "style", "script", "embed", "object", "iframe", "frame", "frameset", "ilayer", "layer", "bgsound", "title", "base");
    $ra2 = array("onabort", "onactivate", "onafterprint", "onafterupdate", "onbeforeactivate", "onbeforecopy", "onbeforecut", "onbeforedeactivate", "onbeforeeditfocus", "onbeforepaste", "onbeforeprint", "onbeforeunload", "onbeforeupdate", "onblur", "onbounce", "oncellchange", "onchange", "onclick", "oncontextmenu", "oncontrolselect", "oncopy", "oncut", "ondataavailable", "ondatasetchanged", "ondatasetcomplete", "ondblclick", "ondeactivate", "ondrag", "ondragend", "ondragenter", "ondragleave", "ondragover", "ondragstart", "ondrop", "onerror", "onerrorupdate", "onfilterchange", "onfinish", "onfocus", "onfocusin", "onfocusout", "onhelp", "onkeydown", "onkeypress", "onkeyup", "onlayoutcomplete", "onload", "onlosecapture", "onmousedown", "onmouseenter", "onmouseleave", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onmousewheel", "onmove", "onmoveend", "onmovestart", "onpaste", "onpropertychange", "onreadystatechange", "onreset", "onresize", "onresizeend", "onresizestart", "onrowenter", "onrowexit", "onrowsdelete", "onrowsinserted", "onscroll", "onselect", "onselectionchange", "onselectstart", "onstart", "onstop", "onsubmit", "onunload");
    $ra  = array_merge($ra1, $ra2);

    $found = true;
    while ($found == true) {
        $val_before = $val;
        for ($i = 0; $i < sizeof($ra); $i++) {
            $pattern = "/";
            for ($j = 0; $j < strlen($ra[$i]); $j++) {
                if ($j > 0) {
                    $pattern .= "(";
                    $pattern .= "(&#[xX]0{0,8}([9ab]);)";
                    $pattern .= "|";
                    $pattern .= "|(�{0,8}([9|10|13]);)";
                    $pattern .= ")*";
                }
                $pattern .= $ra[$i][$j];
            }
            $pattern .= "/i";
            $replacement = substr($ra[$i], 0, 2) . "" . substr($ra[$i], 2);
            $val         = preg_replace($pattern, $replacement, $val);
            if ($val_before == $val) {
                $found = false;
            }
        }
    }
    return $val;
}

3.JSON中文转码

public static function cn_arr_json($arr)
{
    $_var = self::var_urlencode($arr);
    $_str = json_encode($_var);
    return urldecode($_str);
}
public static function var_urlencode($var)
{
    if (empty($var)) {return false;} //判断参数是否为空
    if (is_array($var)) {
        //判断是否为数组
        foreach ($var as $k => $v) {
            if (is_scalar($v)) {
                //if用来处理不是数组的情况
                $var[$k] = urlencode($v);
            } else {
                $var[$k] = self::var_urlencode($v); //else用来处理数组
            }
        }
    } else {
        $var = urlencode($var); //用来处理数组
    }
    return $var;
}

4.ajax返回

public function ajaxJson($state = "success",$msg = "",$params = ""){
    $json = array();
    if($msg){$json["msg"] = $msg;}
    if($params){
        if(is_array($params)){
            foreach($params as $key => $val){
                $json[$key] = $val;
            }
        }else{
            $json["p"] = $params;
        }
    }
    $json["state"] = $state;
    echo json_encode($json);exit;
}

5.微信获取授权
function _diy_wxauth($authurl, $scope = "snsapi_base")
{

$appid=XUETANG_APPID;
$secret = XUETANG_SCRECT;
$code = isset($_GET["code"])?$_GET["code"]:"";
if($code){

//第一步:取得openid

    $oauth2Url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$secret&code=$code&grant_type=authorization_code";
    $oauth2 = getJson($oauth2Url);

//第二步:根据全局access_token和openid查询用户信息

    $access_token = $oauth2["access_token"];
    $openid = $oauth2["openid"];
    $get_user_info_url = "https://api.weixin.qq.com/sns/userinfo?access_token=$access_token&openid=$openid&lang=zh_CN";
    return getJson($get_user_info_url);
}else{
    $redirect_uri = urlencode( WEBSITEURL.$authurl);
    $url ="https://open.weixin.qq.com/connect/oauth2/authorize?appid=$appid&redirect_uri=$redirect_uri&response_type=code&scope=$scope&state=123#wechat_redirect";
    header("Location:".$url);
}

}
//给微信用户发送文字消息
function replyhreftxt($openid, $txt)
{

$access_token = getDxToken();
$url          = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=" . $access_token;
if ($openid && $txt) {
    $datajson = "{"touser":"" . $openid . "","msgtype":"text","text":{"content":"" . $txt . ""}}";
    $res      = http_post($url, $datajson);
    if ($res) {
        return true;
    } else {
        return false;
    }
} else {
    return false;
}

}
6.PHPExcel导出Excel表格
/* 兑换列表导出Excel表格
$isDown 是否下载
$title 表格第一列
$data 需要导出的数据
$filename 文件名
*/

public function actionExceldata()
{
    $isDown=true;

    $objWrite->save($_savePath);exit;*/
    //return $savePath.$fileName.".xlsx";
}

//导出数据，但是不是Excel表格，优点：导出的数据量比较大
*@param $datas array 设置表格数据

*@param $title string 设置表头
*/

public function excelData($datas,$titlename,$title,$filename){
$str = "rnrnrnrn";
$str .="

".$titlename."";

7.生成随机验证码
function getCode()
{

$str = "QWERTYUIOPASDFGHJKLZXCVBNM1234567890qwertyuiopasdfghjklzxcvbnm";
return substr(str_shuffle($str),26,10);

}
8.判断手机号归属地
function phoneCity($account)
{

$url = "http://202.102.221.75:18085/wxservice/hd.jsp";
$serverSign = MD5($account."$"."TTMM%S%XXYY");
$param = array(
    "account" => $account,
    "sign" => $serverSign,
);
$res = CurlPost($url, $param);
$newArr = json_decode($res,true);
return $newArr["ContractRoot"]["SvcCont"]["SOO"][0]["PHONE_LATN_TYPE_RES"][0]["LATN_ID"];

}
9.成功或失败返回ajax

/**
 * 将错误信息返回给Ajax请求
 * @param string $msg 错误信息描述
 * @param integer $code 错误代码，默认1
 */
public function ajaxError($msg = "", $code = 1)
{
    $this->ajaxEcho([
        "error" => $code,
        "msg" => $msg,
    ]);
}

/**
 * 将成功信息返回给Ajax请求
 * @param mix $data 返回数据
 */
public function ajaxSuccess($data = "")
{
    $this->ajaxEcho([
        "error" => 0,
        "data" => $data,
    ]);
}

/**
 * 一般情况下直接使用ajaxSuccess和ajaxError可以满足绝大部分需求
 * 考虑灵活性，本函数设置为公开，以满足特殊需求
 */
public function ajaxEcho($arr)
{
    header("Content-type:application/json;charset=utf-8");
    echo json_encode($arr);
    exit;
}

10.正则表达式

function regex($value,$rule) {
    $validate = array(
            "require"   =>  "/S+/",
            "email"     =>  "/^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*$/",
            "url"       =>  "/^http(s?)://(?:[A-za-z0-9-]+.)+[A-za-z]{2,4}(?:[/?#][/=?%-&~`@[]":+!.#w]*)?$/",
            "currency"  =>  "/^d+(.d+)?$/",
            "number"    =>  "/^d+$/",
            "qq"        =>  "/^d*$/",
            "telephone" =>  "/^0([1-9]{3})([0-9]{7,8})$/",
            "zip"       =>  "/^d{6}$/",
            "integer"   =>  "/^[-+]?d+$/",
            "double"    =>  "/^[-+]?d+(.d+)?$/",
            "english"   =>  "/^[A-Za-z]+$/",
            "mobile"    =>  "/^1[3-9]{1}[0-9]{1}[0-9]{8}$/",
    );
    // 检查是否有内置的正则表达式
    if(isset($validate[strtolower($rule)]))
        $rule       =   $validate[strtolower($rule)];
    return preg_match($rule,$value)===1;
}
