微信公众号主动给用户发送信息的方法:首先在公众号后台功能模块中添加“客服功能”模块;然后获取“access_token”并调用发送方法;最后在使用时直接调用“sendmsg()”方法传值即可。
微信公众号怎么主动给用户发送信息?
首先,先在公众号后台功能模块中-》添加功能模块 添加 客服功能 模块
如图所示:
然后就进入代码环节了。
先添加客服。也可以公众号后台添加
//先添加客服 function addkf() { $token = getToken(); $url = ‘https://api.weixin.qq.com/customservice/kfaccount/add?access_token=‘.$token; $data = ‘{ "kf_account" : "system@system", "nickname" : "客服1", "password" : "admin", }‘; echo https_request($url,$data); }
然后就是主动发送消息的方法
//获取access_token的方法。 function getToken() { $appid = ‘appid‘; $appsecret = ‘appsecret‘; $token_file = dirname(dirname(__FILE__)).‘/data/token.txt‘; if(!file_exists($token_file) || ((time() - filemtime($token_file)) > 7000)){ $TOKEN_URL="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$appsecret; $json=file_get_contents($TOKEN_URL); $result=json_decode($json); $ACC_TOKEN=$result->access_token; file_put_contents($token_file,$ACC_TOKEN); }else{ $ACC_TOKEN = file_get_contents($token_file); } return $ACC_TOKEN; } //调用发送方法 function sendmsg($content,$openid) { $token = getToken(); $url = ‘https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=‘.$token; $content = ‘感谢你的关注\n回复你厉害 \n例如<a href=\"http://www.baidu.com\">回复123456</a>‘; $data = ‘{ "touser":"‘.$openid.‘", "msgtype":"text", "text": { "content":"‘.$content.‘" } }‘; https_request($url,$data); return true; } /** * request 请求 */ function https_request($url, $data = null){ $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); if (!empty($data)){ curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); return $output; }
使用的时候直接调用 sendmsg()方法传值就可以了。
最后上完成的图
如图所示,公众号可以给用户发送消息,而且发送的内容你可以使用html 标签哦
虽然这样感觉很方便,但是同样,微信公众平台对此也有限制。
1.用户必须关注公众号,方可收到信息。
2.用户只能连续收到 20 条客服消息。超过后用户就收不到消息,
超过后,用户必须 主动给公众号发送消息 。或者 点击菜单栏,这样20条消息的限制就会重置。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
