  • 1、申请地址:https://open.weixin.qq.com/

    2、填写开发资料:

    说明:授权事件接收URL,用于获取微信服务器每10分钟推送的ComponentVerifyTicket,该Tikict 用于获取三方平台的component_access_token,而component_access_token则用于获取预授权码pre_auth_code,授权码换取公众号的授权信,预授权码:该API用于使用授权码换取授权公众号的授权信息,并换取authorizer_access_token和authorizer_refresh_token。 授权码的获取,需要在用户在第三方平台授权页中完成授权流程后,在回调URI中通过URL参数提供给第三方平台方。授权成功会返回授权公众号的授权信息,值得注意的是,authorizer_refresh_token必须保存好,authorizer_refresh_token是被授权公众号获取authorizer_access_token(相当于普通的access_token)的凭证,否则需要重新授权才能获取。

    3、配置

    如下:(注:所有消息收发均要加解密,主动调用的接口不包括)

    html' target='_blank'>public function sysmessage(){import('@.ORG.aes.WXBizMsgCrypt');        $wxData = $this->weixin_account;        $encodingAesKey = $wxData['encodingAesKey'];        $token = $wxData['token'];        $appId = $wxData['appId'];        $timeStamp  = empty($_GET['timestamp'])     ? ''    : trim($_GET['timestamp']) ;         $nonce      = empty($_GET['nonce'])     ? ''    : trim($_GET['nonce']) ;         $msg_sign   = empty($_GET['msg_signature']) ? ''    : trim($_GET['msg_signature']) ;        $encryptMsg = file_get_contents('php://input');        $pc = new WXBizMsgCrypt($token, $encodingAesKey, $appId);                $xml_tree = new DOMDocument();        $xml_tree->loadXML($encryptMsg);        $array_e = $xml_tree->getElementsByTagName('Encrypt');        $encrypt = $array_e->item(0)->nodeValue;        $format = '<xml><ToUserName><![CDATA[toUser]]></ToUserName><Encrypt><![CDATA[%s]]></Encrypt></xml>';        $from_xml = sprintf($format, $encrypt);        // 第三方收到公众号平台发送的消息        $msg = '';        $errCode = $pc->decryptMsg($msg_sign, $timeStamp, $nonce, $from_xml, $msg);        if ($errCode == 0) {            //print('解密后: ' . $msg . '');            $xml = new DOMDocument();            $xml->loadXML($msg);            $array_e = $xml->getElementsByTagName('ComponentVerifyTicket');            $component_verify_ticket = $array_e->item(0)->nodeValue;            //logResult('解密后的component_verify_ticket是:'.$component_verify_ticket);            $dateline = time();            $date_time = date('Y-m-d H:i:s',time());            $data = array(                'component_verify_ticket'=>$component_verify_ticket,                'token_expires'=>$dateline+600,                'date_time'=>$date_time,            );            $res = M('weixin_account')->where(array('appId'=>$this->component_appid))->save($data);            if($res)            {                $weixin_account = M('weixin_account')->where(array('appId'=>$this->component_appid))->find();                S('weixin_account'.$this->component_appid,$weixin_account,600);                echo 'success';            }                    } else {            //logResult('解密后失败:'.$errCode);            //$res = M('weixin_account')->where(array('appId'=>$this->component_appid))->save(array('text'=>'fasle'));            print($errCode . '');        }        die();}

    获取授权跳转链接:

    	//获取授权回调URL	public function auth(){		if (IS_POST) {			$pre_auth_code = $this->weObj->get_auth_code();					$token = $this->weObj->getAccessToken();			$callback = U('Index/oauth_back','',true,false,true);			$url = $this->weObj->getRedirect($callback,$pre_auth_code);			$this->ajaxReturn($url);		}else {			$this->ajaxReturn('error');		}	}

      

    格式:

    <a href='https://mp.weixin.qq.com/cgi-bin/componentloginpage?component_appid=wx07068eax27ef6eed&pre_auth_code=preauthcode@@@lVMrqq7UdbhIQj1-IwlrtYSXIoIghSSgPrWQmSgzSVChVdQJgJ2iAInQOqURpqFU&redirect_uri=http%3A%2F%2Fsmg.xxx.cn%2Findex.php%3Fg%3DUser%26m%3DIndex%26a%3Doauth_back' id='authurl' style='display: inline;'><img src='https://open.weixin.qq.com/zh_CN/htmledition/res/assets/res-design-download/icon_button3_1.png'></a>

      

    点击进行授权:

    再点击登陆并且授权的时候,会要求用管理员微信扫一扫确认授权。

    授权成功后就得到被授权公众号的授权信息了,包括appId,authorizer_access_token,authorizer_refresh_token,头像,公众号类型等信息,其中authorizer_refresh_token必须完整保存好。

    这样就可以完成一个公众号的授权了。

    3、处理消息

    	//公众号消息与事件接收URL//此处为实例,逻辑需要自己处理,(注意加解密)	public function eventmsg(){    	    import('@.ORG.aes.WXBizMsgCrypt');			$wxData = $this->weixin_account;			$encodingAesKey = $wxData['encodingAesKey'];			$token = $wxData['token'];			$appId = $wxData['appId'];			$timeStamp  = empty($_GET['timestamp'])     ? ''    : trim($_GET['timestamp']) ;			$nonce      = empty($_GET['nonce'])     ? ''    : trim($_GET['nonce']) ;			$msg_sign   = empty($_GET['msg_signature']) ? ''    : trim($_GET['msg_signature']) ;						$encryptMsg = file_get_contents('php://input');			$pc = new WXBizMsgCrypt($token, $encodingAesKey, $appId);						$xml_tree = new DOMDocument();			$xml_tree->loadXML($encryptMsg);			$array_e = $xml_tree->getElementsByTagName('Encrypt');			$encrypt = $array_e->item(0)->nodeValue;									$format = '<xml><ToUserName><![CDATA[toUser]]></ToUserName><Encrypt><![CDATA[%s]]></Encrypt></xml>';			$from_xml = sprintf($format, $encrypt);                // 第三方收到公众号平台发送的消息			$msg = '';              $errCode = $pc->decryptMsg($msg_sign, $timeStamp, $nonce, $from_xml, $msg);						if ($errCode == 0) {					//print('解密后: ' . $msg . '');					$xml = new DOMDocument();					$xml->loadXML($msg);										$array_e = $xml->getElementsByTagName('Content');					$content = $array_e->item(0)->nodeValue;									$array_e2 = $xml->getElementsByTagName('ToUserName');					$ToUserName = $array_e2->item(0)->nodeValue;									$array_e3 = $xml->getElementsByTagName('FromUserName');					$FromUserName = $array_e3->item(0)->nodeValue;															$array_e5 = $xml->getElementsByTagName('MsgType');					$MsgType = $array_e5->item(0)->nodeValue;						//加密消息					$encryptMsg = '';					$text = '<xml>					<ToUserName><![CDATA[$FromUserName]]></ToUserName>					<FromUserName><![CDATA[$ToUserName]]></FromUserName>					<CreateTime>$stime</CreateTime>					<MsgType><![CDATA[text]]></MsgType>					<Content><![CDATA[$contentx]]></Content>					</xml>';									$errCode = $pc->encryptMsg($text, $timeStamp, $nonce, $encryptMsg);					echo $encryptMsg;                        exit();						} else {				print($errCode . '');				exit();			}	}    

      到此授权基本完成了。

    4、全网发布检测

             if ($MsgType=='text') {                    $needle ='QUERY_AUTH_CODE:';                    $tmparray = explode($needle,$content);                    if(count($tmparray)>1){                        //3、模拟粉丝发送文本消息给专用测试公众号,第三方平台方需在5秒内返回空串                        //表明暂时不回复,然后再立即使用客服消息接口发送消息回复粉丝                                                        $contentx = str_replace ($needle,'',$content);                        $info = $this->weObj->get_authorization_info($contentx);                        $test_token = $info['authorizer_access_token'];                        $content_re = $contentx.'_from_api';                        echo '';                        $data = '{                            'touser':''.$FromUserName.'',                            'msgtype':'text',                            'text':                            {                                 'content':''.$content_re.''                            }                        }';                                            $url = 'https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token='.$test_token;                        $this->https_post($url, $data);                                        } else{                        //2、模拟粉丝发送文本消息给专用测试公众号                        $contentx = 'TESTCOMPONENT_MSG_TYPE_TEXT_callback';                    }                }                                                    //1、模拟粉丝触发专用测试公众号的事件                if ($MsgType=='event') {                    $array_e4 = $xml->getElementsByTagName('Event');                    $event = $array_e4->item(0)->nodeValue;                    $contentx = $event.'from_callback';                                    }

    效果:

    检测

    成功

    到此全网发布完成
