How to use PHP to implement the template message sending function of public accounts

In recent years, with the rapid growth of the number of users of WeChat public accounts, more and more enterprises and Individuals began to pay attention to the development of WeChat public accounts. Among them, template messages are one of the commonly used functions in public account development. Template messages can be used to send fixed-format messages to users and provide various services and information. This article will introduce how to use PHP to implement the template message sending function of public accounts, and provide specific code examples.

First of all, in order to realize the template message sending function of the public account, we need to meet the following conditions:

  1. Have a certified WeChat public account (including subscription account, service account and enterprise account);
  2. Obtain the AppID and AppSecret of the official account;
  3. Apply on the WeChat public platform and obtain the template ID of the template message.

1. Obtain Access Token

Before sending the template message, we need to obtain the Access Token as a credential for accessing the WeChat API interface. Access Token has a certain validity period and needs to be obtained again after expiration.

We can obtain the Access Token through the following code:

function getAccessToken($appId, $appSecret) {
    $apiUrl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $appId . "&secret=" . $appSecret;
    $response = file_get_contents($apiUrl);
    $result = json_decode($response, true);
    
    // Check if access token is valid
    if(isset($result['access_token'])) {
        return $result['access_token'];
    } else {
        // Handle error
        return false;
    }
}

$accessToken = getAccessToken($appId, $appSecret);

2. Send template message

After obtaining the Access Token, we can use the Token to send the template message. The following is a sample code to send template messages to users:

function sendTemplateMessage($accessToken, $openId, $templateId, $data) {
    $apiUrl = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=" . $accessToken;

    $postData = array(
        'touser' => $openId,
        'template_id' => $templateId,
        'data' => $data
    );

    $jsonData = json_encode($postData);

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $apiUrl);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
    $response = curl_exec($ch);
    curl_close($ch);

    // Handle response
    return $response;
}

// 要发送的模板消息的数据
$templateData = array(
    'first' => array('value' => '您好', 'color' => '#173177'),
    'keyword1' => array('value' => '模板消息', 'color' => '#173177'),
    'keyword2' => array('value' => '2020-01-01', 'color' => '#173177'),
    'remark' => array('value' => '感谢您的使用', 'color' => '#173177')
);

$response = sendTemplateMessage($accessToken, $openId, $templateId, $templateData);

// 处理发送结果
$result = json_decode($response, true);
if($result['errcode'] == 0) {
    echo "模板消息发送成功!";
} else {
    echo "模板消息发送失败,请稍后重试。错误信息:" . $result['errmsg'];
}

In the above code, we first define a sendTemplateMessage function for sending template messages. This function needs to pass in Access Token, user OpenID, template ID and template message data.

The data of the template message is an associative array, in which the field names correspond to the variable names in the template one-to-one.

Finally, we send the template message by calling the sendTemplateMessage function and process the sending result.

Summary:

This article introduces how to use PHP to implement the template message sending function of WeChat public accounts. First, we need to obtain the Access Token and then use the Token to send the template message. Through the above code examples, we hope to help developers successfully implement the template message sending function of official accounts.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.
