PHP implements WeChat template messages to be sent to specified users

I have received a lot of inquiries from children’s shoes. Can I send a message to a certain user using the interface of the WeChat public account? If I send it directly, there are some restrictions. One is the customer service message interface, but this requires the user to wait within 48 hours. It can only be sent if there is interaction with the public account. The other one is WeChat’s template message, which has no sending time limit, but WeChat needs to use a template to prevent some spam data before it can be sent.

I believe we usually receive a lot of template messages, the actual effect is as follows:

This kind How to achieve the effect of WeChat template messages?

First, you need to select template messages in the "Function" menu in the WeChat public platform background. If there is no template message in the menu, you need to click on the function plug-in to add it, as follows Figure:

After adding the plug-in, you can select a template in the template library to use. Of course, you can also create a template. Generally speaking, the template library is enough. After selecting a template, you must remember the template ID. This will be done later. Used in PHP programs.

Next, let’s talk about the calling rules of the interface:

http request method: POST

https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=ACCESS_TOKEN

What format of data is sent? The data sent is in json format, take the following template as an example:

The JSON format is as follows:

{
"touser": "这里是接收用户的OPENID",
"template_id": "这里是模板ID",
"url": "这里是点击详情后跳转的网址",
"data": {
"first": {
"value": "您好!有访客访给您留言了。",
"color": "#173177"
},
"user": {
"value": "张三",
"color": "#FF0000"
},
"ask": {
"value": "您好,非常关注黎明互联,有没有关于支付宝的视频教程?",
"color": "#173177"
},
"remark": {
"value": "该用户已注册12天",
"color": "blue"
}
}
}

Data format Now we understand, then how to use PHP to send it to the server, and in the code Can JSON only be defined as a string after data splicing is completed? If you are not familiar with strings or don’t like using strings, you can use array conversion. The following uses an array as an example to give a PHP code snippet to implement a WeChat template message:

class WxTmp
{
    //请求模板消息的地址
    const TEMP_URL = 'https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=';
    public function getAccessToken(){
        //这里获取accesstoken  请根据自己的程序进行修改
        return $access_token;
    }
    /**
    * 微信模板消息发送
    * @param $openid 接收用户的openid
    * return 发送结果
    */
    public function send($openid){
        $tokens = $this->getAccessToken();
        $url = self::TEMP_URL . $tokens;
        $params = [
            'touser' => $openid,
            'template_id' => 'Oblr5uXH_fS79gMC8E0mYz0CpUAHnJtdvAC3PWABrsk',//模板ID
            'url' => 'https://www.liminghulian.com/course/3/lesson/list', //点击详情后的URL可以动态定义
            'data' => 
                    [
                      'first' =>

                         ],
                      'user' => 
                         [
                            'value' => '张三',
                            'color' => '#FF0000'
                         ],
 
                      'ask' => 
                         [
                                'value' => '您好,非常关注黎明互联,有没有关于支付宝的视频教程?',
                                'color' => '#173177'
                         ],
                       'remark' => 
                         [
                                'value' => '该用户已注册12天',
                                'color' => 'blue'
                         ] 
                      ]
        ]; 
        $json = json_encode($params,JSON_UNESCAPED_UNICODE);
        return $this->curlPost($url, $json);
    }
    /**
    * 通过CURL发送数据
    * @param $url 请求的URL地址

    * return 请求结果

    protected function curlPost($url,$data)
    {
        $ch = curl_init();
