微信公眾號(hào)第三方開發(fā)平臺(tái)(一)

之前的文章是獲取調(diào)用接口的一些基本參數(shù)，繼續(xù)開發(fā)微信開放平臺(tái)。

    public function tiaozhuan()
    {
        $info = getData("system_config", array("type" => "pre_auth_code"), array(), 1);    ////獲取保存在數(shù)據(jù)庫中的pre_auth_code
        $pre_auth_code = $info["value"];
        $back_url = "http://www.xxxxxx.com/index.php/$APPID$/callback";   //后臺(tái)設(shè)置的回調(diào)地址，用戶掃完二維碼之后會(huì)跳轉(zhuǎn)到這個(gè)連接    
        $url = "https://mp.weixin.qq.com/cgi-bin/componentloginpage?component_appid=wxcda7bf3c4bf44cdc&pre_auth_code=".$pre_auth_code."&redirect_uri=".$back_url;
        header("Location:".$url);
    }

    //保存公眾號(hào)信息
    private function saveOpenWeixin()
    {
        //獲取公眾號(hào)access
        $info = getData("system_config", array("type" => "component_access_token"), array() , 1); //獲取保存在數(shù)據(jù)庫中的component_access_token
        $component_access_token = $info["value"];
        $url = "https://api.weixin.qq.com/cgi-bin/component/api_query_auth?component_access_token=".$component_access_token;
        $auth_code = $_GET["auth_code"];
        $post = array(
            "component_appid" => $this->appid,    //應(yīng)用的appid
            "authorization_code"    => $auth_code,
        );
        $ret=send_post($url, $post);
        $author = json_decode($ret, True);
        //獲取公眾號(hào)信息
        $url = "https://api.weixin.qq.com/cgi-bin/component/api_get_authorizer_info?component_access_token=".$component_access_token;
        $authorAppid = $author["authorization_info"]["authorizer_appid"];
        $post = array(
            "component_appid" => $this->appid,
            "authorizer_appid" => $authorAppid,
        );
        $ret = send_post($url, $post);
        $userInfo = json_decode($ret, True);
        
        //公眾號(hào)信息
        $authorInfo = $author["authorization_info"];

    }

//獲取授權(quán)方的公眾號(hào)帳號(hào)基本信息
    public function demo6()
    {
        $info = getData("system_config", array("type" => "component_access_token"), array(), 1);  //獲取保存在數(shù)據(jù)庫中的component_access_token
        $token = $info["value"];
        $url = "https://api.weixin.qq.com/cgi-bin/component/api_get_authorizer_info?component_access_token=".$token;
        $post = array(
            "component_appid" => $this->appid,
            "authorizer_appid" => "xxxxxxxxxx",  //公眾號(hào)appid
        );
        $ret = send_post($url, $post);
        $res = json_decode($ret, True);
    }
    
    //微信賬號(hào)網(wǎng)頁授權(quán)
    public function demo8()
    {
        $appid = "xxxx"; //公眾號(hào)的appid
        $redirect = site_url("toupiao/".$appid."/callback");
        //$scope = "snsapi_base";
        $scope = "snsapi_userinfo";   //獲取方式
        $state = "omllz";
        $component_appid = $this->appid;  //應(yīng)用的appid
        $url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=".$appid."&redirect_uri=".$redirect."&response_type=code&scope=".$scope."&state=".$state."&component_appid=".$component_appid."#wechat_redirect";
        header("Location:".$url);
    }
