PHP implementation of WeChat applet reading statistics skills

With the rise of WeChat mini programs, more and more developers are beginning to use it to promote their products and services. However, the subsequent problem is how to accurately count the reading volume of the mini program in order to optimize the promotion effect and improve the user conversion rate. This article will introduce some PHP techniques for implementing WeChat applet reading statistics to provide a reference for developers.

1. The principle of reading statistics of WeChat mini programs

The reading statistics of WeChat mini programs are similar to the reading statistics of WeChat public accounts, and are implemented based on the interface provided by WeChat public platform . Specifically, developers need to add the original ID and AppSecret of an official account to the mini program, and then use the JS interface provided by WeChat to obtain the user's WeChat OpenID and login status to send an access statistics request to the WeChat server.

2. Preparation work

Before starting, developers need to complete the following preparation work:

1. Register a public account on the WeChat public platform and bind it A small program.
2. Add the original ID and AppSecret of the official account in the mini program.
3. Obtain WeChat JS-SDK (you can apply for it on the WeChat open platform).
4. Use the CURL library to implement HTTP requests in PHP.

3. Implementation process

The following is the specific process for implementing WeChat mini program reading statistics:

1. Obtain the login status and OpenID of the current user in the mini program. Code example:

wx.login({
  success: function(res) {
    if (res.code) {
      wx.request({
        url: 'https://api.weixin.qq.com/sns/jscode2session?appid=' + appid + '&secret=' + secret + '&js_code=' + res.code + '&grant_type=authorization_code',
        success: function(res) {
          openid = res.data.openid;
          session_key = res.data.session_key;
        }
      });
    } else {
      console.log('获取用户登录态失败！' + res.errMsg);
    }
  }
})

2. Construct the request URL and use the CURL library to send the HTTP request. Code example:

$url = 'https://api.weixin.qq.com/datacube/getweanalysisappidvisitpage?access_token=' . $access_token;
$data = array(
    'begin_date' => $begin_date,
    'end_date' => $end_date,
    'page_id' => $page_id,
    'page_path' => $page_path,
    'openid' => $openid
);
$options = array(
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => json_encode($data)
);
$curl = curl_init($url);
curl_setopt_array($curl, $options);
$result = curl_exec($curl);
curl_close($curl);

3. Parse the returned results and return reading data. Code example:

$result = json_decode($result, true);
$visit_data = $result['list'][0]['page_visit_pv'];
echo $visit_data;

4. Summary

This article introduces some techniques for implementing WeChat applet reading statistics in PHP, hoping to provide a reference for developers. It should be noted that in order to ensure the accuracy of statistical data, it is recommended to use the interface provided by WeChat in the mini program to implement reading statistics, and do not use third-party tools or plug-ins.
