微信官方包代碼修改

獲取openid州刽，type為openid獲取方式

public function GetOpenid($type)
{
    //通過(guò)code獲得openid
    if (!isset($_GET['code'])){
        //觸發(fā)微信返回code碼
        $baseUrl = urlencode('http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'].$_SERVER['QUERY_STRING']);
        $url = $this->_CreateOauthUrlForCode($baseUrl,$type);
        Header("Location: $url");
        exit();
    } else {
        //獲取code碼空执，以獲取openid
        $code = $_GET['code'];
        $openid = $this->getOpenidFromMp($code);
        return $openid;
    }
}

這里傳入type，區(qū)分授權(quán)方式

private function _CreateOauthUrlForCode($redirectUrl,$type)
{
    $config = new WxPayConfig();
    $urlObj["appid"] = $config->GetAppId();
    $urlObj["redirect_uri"] = "$redirectUrl";
    $urlObj["response_type"] = "code";
    $urlObj["scope"] = $type;

    $urlObj["state"] = "STATE"."#wechat_redirect";
    $bizString = $this->ToUrlParams($urlObj);
    return "https://open.weixin.qq.com/connect/oauth2/authorize?".$bizString;
}


public function GetOpenidFromMp($code)
{
    $url = $this->__CreateOauthUrlForOpenid($code);

    //初始化curl
    $ch = curl_init();
    $curlVersion = curl_version();
    $config = new WxPayConfig();
    $ua = "WXPaySDK/3.0.9 (".PHP_OS.") PHP/".PHP_VERSION." CURL/".$curlVersion['version']." "
    .$config->GetMerchantId();

    //設(shè)置超時(shí)
    //curl_setopt($ch, CURLOPT_TIMEOUT, $this->curl_timeout);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,FALSE);
    curl_setopt($ch, CURLOPT_USERAGENT, $ua);
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

    $proxyHost = "0.0.0.0";
    $proxyPort = 0;
    $config->GetProxy($proxyHost, $proxyPort);
    if($proxyHost != "0.0.0.0" && $proxyPort != 0){
        curl_setopt($ch,CURLOPT_PROXY, $proxyHost);
        curl_setopt($ch,CURLOPT_PROXYPORT, $proxyPort);
    }
    //運(yùn)行curl穗椅，結(jié)果以jason形式返回
    $res = curl_exec($ch);
    curl_close($ch);
    //取出openid
    $data = json_decode($res,true);
    $this->data = $data;
    $openid = $data;
    return $openid;
}

獲取openid

public function getOpenids()
{
    $obj = new \JsApiPay();
    $data = $obj->GetOpenid("snsapi_userinfo");
    return $data;
}

public function getOpenid()
{
      session_start();
      $obj = new \JsApiPay();
      $data = $obj->GetOpenid("snsapi_base");
      $_SESSION['openid'] = $data['openid'];
}

curlGet

public static function curlGet($url = '', $options = array())
{
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    if (!empty($options)) {
        curl_setopt_array($ch, $options);
    }
    //https請(qǐng)求 不驗(yàn)證證書和host
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

獲取access_token并保存至數(shù)據(jù)庫(kù)維護(hù)

public function getWxAccessToken()
{
    $access_token = db('access_token')->where("id>0")->find();
    if ($access_token) {
        $endtime = $access_token['inserttime'] + 7000;
        if ($access_token['access_token'] && $endtime > time()) {
            //如果access_token在session沒有過(guò)期
            return $access_token['access_token'];
        } else {
            //如果access_token比存在或者已經(jīng)過(guò)期脆烟，重新取access_token
            //1 請(qǐng)求url地址
            $config = new \WxPayConfig();
            $AppId = $config->GetAppId();
            $AppSecret = $config->GetAppSecret();
            $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $AppId . "&secret=" . $AppSecret;
            $res = $this->http_curl($url, 'get', 'json');
            $res = json_decode($res, true);

            $access_token = $res['access_token'];
            //將重新獲取到的aceess_token存到session
            $update_data = [
                'inserttime' => time(),
                'access_token' => $access_token
            ];
            $update_data = db('access_token')->where("id>0")->update($update_data);
            return $access_token;
        }
    } else {
        $config = new \WxPayConfig();
        $AppId = $config->GetAppId();
        $AppSecret = $config->GetAppSecret();
        $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $AppId . "&secret=" . $AppSecret;
        $res = $this->http_curl($url, 'get', 'json');
        $res = json_decode($res, true);

        $access_token = $res['access_token'];
        //將重新獲取到的aceess_token存到session
        $update_data = [
            'inserttime' => time(),
            'access_token' => $access_token
        ];
        $update_data = db('access_token')->insert($update_data);
        return $access_token;
    }

}

獲取用戶信息

public function getUserdata($openid,$access_token)
{
    $response = self::curlGet('https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token.'&openid='.$openid.'&lang=zh_CN');
    return json_decode($response,true);
}

將用戶信息存入session并返回

public function getuser()
{
    session_start();
    $data = $this->getOpenids();
    $openid = $data['openid'];
    $access_token = $data['access_token'];
    $data = $this->getUserdata($openid,$access_token);
    $_SESSION['user'] = $data;
    $this->redirect('調(diào)回路由');
}

獲取公眾號(hào)微信config

public function getwxconfig()
{
    //session_start();
    $token = $this->getWxAccessToken();
    $urls = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=$token&type=jsapi";
    //https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=ACCESS_TOKEN&type=jsapi
    $jsapi = file_get_contents($urls);
    $arr = json_decode($jsapi, true);

    //獲取jsapi_ticket
    $jsapi_ticket = $arr['ticket'];
    //隨機(jī)字符串
    $noncestr = $this->getRandChar(16);
    //獲取時(shí)間戳
    $timestamp = strtotime(date("Y-m-d H:i:s"));
    //獲取url
    $config = new \WxPayConfig();
    $AppId = $config->GetAppId();

    $url = input('url');
    //$data = array("jsapi_ticket"=>$jsapi_ticket,"noncestr"=>$noncestr,"timestamp"=>$timestamp,"url"=>$url);
    $sha1 = sha1("jsapi_ticket=$jsapi_ticket&noncestr=$noncestr&timestamp=$timestamp&url=$url");
    $arr = array('appid' => $AppId, 'noncestr' => $noncestr, 'timestamp' => $timestamp, 'sha1' => $sha1);
    return json($arr);
}

微信字符串

public function getRandChar($length)
{
    $str = null;
    $strPol = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz";
    $max = strlen($strPol) - 1;
    for ($i = 0; $i < $length; $i++) {
        $str .= $strPol[rand(0, $max)];//rand($min,$max)生成介于min和max兩個(gè)數(shù)之間的一個(gè)隨機(jī)整數(shù)
    }
    return $str;
}

初始化設(shè)置

public function configall()
{
    $this->getOpenid();//靜默獲取openid
    $this->getwxconfig();//獲取wxconfig參數(shù)
    $this->redirect("跳轉(zhuǎn)路由");
}
