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用于和appid,appscret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)
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 . "\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(\'解密后失败:\'.$errCode);
//$res = M(\'weixin_account\')->where(array(\'appId\'=>$this->component_appid))->save(array(\'text\'=>\'fasle\'));
print($errCode . "\n");
}
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 . "\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:
