1、申請地址:https://open.weixin.qq.com/
2、填寫開發資料:
說明:授權事件接收URL,用於獲取微信服務器每10分鍾推送的ComponentVerifyTicket,該Tikict用於和appid,appscret獲取三方平台的 component_access_token,而component_access_token 則用於獲取預授權碼pre_auth_code,授權碼換取公眾號的授權信,預授權碼:該API用於使用授權碼換取授權公眾號的授權信息,並換取authorizer_access_token和authorizer_refresh_token。 授權碼的獲取,需要在用戶在第三方平台授權頁中完成授權流程后,在回調URI中通過URL參數提供給第三方平台方。授權成功會返回授權公眾號的授權信息,值得注意的是,authorizer_refresh_token必須保存好,authorizer_refresh_token是被授權公眾號獲取authorizer_access_token(相當於普通的access_token)的憑證,否則需要重新授權才能獲取。
3、配置
如下:(注:所有消息收發均要加解密,主動調用的接口不包括)
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); // 第三方收到公眾號平台發送的消息 $msg = ''; $errCode = $pc->decryptMsg($msg_sign, $timeStamp, $nonce, $from_xml, $msg); if ($errCode == 0) { //print("解密后: " . $msg . "\n"); $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('解密后失敗:'.$errCode); //$res = M('weixin_account')->where(array('appId'=>$this->component_appid))->save(array('text'=>'fasle')); print($errCode . "\n"); } die(); }
獲取授權跳轉鏈接:
//獲取授權回調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>
點擊進行授權:
再點擊登陸並且授權的時候,會要求用管理員微信掃一掃確認授權。
授權成功后就得到被授權公眾號的授權信息了,包括appId,authorizer_access_token,authorizer_refresh_token,頭像,公眾號類型等信息,其中authorizer_refresh_token必須完整保存好。
這樣就可以完成一個公眾號的授權了。
3、處理消息
//公眾號消息與事件接收URL //此處為實例,邏輯需要自己處理,(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); // 第三方收到公眾號平台發送的消息 $msg = ''; $errCode = $pc->decryptMsg($msg_sign, $timeStamp, $nonce, $from_xml, $msg); if ($errCode == 0) { //print("解密后: " . $msg . "\n"); $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 . "\n"); exit(); } }
到此授權基本完成了。
4、全網發布檢測
if ($MsgType=="text") {
$needle ='QUERY_AUTH_CODE:'; $tmparray = explode($needle,$content); if(count($tmparray)>1){ //3、模擬粉絲發送文本消息給專用測試公眾號,第三方平台方需在5秒內返回空串 //表明暫時不回復,然后再立即使用客服消息接口發送消息回復粉絲 $contentx = str_replace ($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、模擬粉絲發送文本消息給專用測試公眾號 $contentx = "TESTCOMPONENT_MSG_TYPE_TEXT_callback"; } } //1、模擬粉絲觸發專用測試公眾號的事件 if ($MsgType=="event") { $array_e4 = $xml->getElementsByTagName('Event'); $event = $array_e4->item(0)->nodeValue; $contentx = $event."from_callback"; }
效果:
檢測
成功
到此全網發布完成
