微信公众号报redirect_uri参数错误（站点申请http后）

更改get_code方法：

/**
 * 获取授权code
 */
function get_code($appid){
    $url = get_url();
    if (strpos($url, '?') === false) {
        $url .= '?getOpenId=1';
    } else {
        $url .= '&getOpenId=1';
    }
    $stulr=str_replace('https://'.SITE_DOMAIN.':443', 'http://'.SITE_DOMAIN, $url);
    $_SESSION['wx_codequan']=1;
    $redirect_uri = urlencode($stulr);
    //获取code后，请求以下链接获取access_token：
    $oauth2_url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=" . $appid . "&redirect_uri=" . $redirect_uri . "&response_type=code&scope=snsapi_base&state=123#wechat_redirect";
    header("location: $oauth2_url");
}
更改get_openid方法

/**
 * 获取微信返回用户openid
 */
function get_openid($code = ""){
    if (SITE_DOMAIN == 'localhost' || SITE_DOMAIN == '127.0.0.1' || SITE_DOMAIN == 'www.test44.com' || SITE_DOMAIN == '192.168.1.200' || SITE_DOMAIN == '192.168.1.110') {
        return "1";
    }
    if (@$_SESSION["openid"] != "") {
        return @$_SESSION["openid"];
        exit;
    }
    $wx_public = get_public();
    $appid = $wx_public['appid'];
    $appsecret = $wx_public['secret'];
    $code = arg("code", "");
    $getOpenId = arg("getOpenId", "");

    if ($code == "" && $getOpenId == "") {
        get_code($appid);
        exit();
    }
    if(!$_SESSION['wx_codequan']){
        get_code($appid);
        exit();
    }
    $oauth2_code = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=" . $appid . "&secret=" . $appsecret . "&code=" . $code . "&grant_type=authorization_code";
    $content = https_request($oauth2_code);
    $token = @json_decode($content, true);
    if (empty($token) || !is_array($token) || empty($token['access_token']) || empty($token['openid'])) {
        die(error_msg($token));
    }
    $_SESSION["openid"] = $token['openid'];
    return $token['openid'];
