How to use PHP to implement multiple customer service functions of public accounts

With the popularity of WeChat public accounts, companies and individuals are eager to communicate with users in real time through WeChat public accounts comminicate. The multi-customer service function is an important function provided by the WeChat official account, which allows enterprises to have one-to-one real-time conversations with users through the customer service system. This article will introduce how to use PHP to implement the multi-customer service function of public accounts and provide specific code examples.

1. Preparation work

First of all, in order to use PHP to implement the multi-customer service function of the WeChat public account, you need to prepare the following basic conditions:

• Developer account of WeChat public account
• An accessible PHP server
• Developer documentation of WeChat public platform

2. Get interface calling credentials

Before we start writing code, we need to obtain the interface calling credentials (Access Token) provided by the WeChat public platform. Access Token is a globally unique credential used to call the WeChat interface and is valid for 7200 seconds.

The following is an example of PHP code to obtain Access Token:

<?php
$appId = "your_app_id";
$appSecret = "your_app_secret";

$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appId."&secret=".$appSecret;

$response = file_get_contents($url);
$result = json_decode($response, true);
$accessToken = $result['access_token'];

echo "Access Token: ".$accessToken;
?>

Save the above code as the get_access_token.php file and access the file in the browser to obtain the Access Token.

3. Add customer service account

Before using the multi-customer service function, we need to add a customer service account first. The following is an example of PHP code for adding a customer service account:

<?php
$kfAccount = "your_kf_account";
$nickname = "your_nickname";
$password = "your_password";

$url = "https://api.weixin.qq.com/customservice/kfaccount/add?access_token=".$accessToken;

$data = [
    "kf_account" => $kfAccount,
    "nickname" => $nickname,
    "password" => md5($password)
];

$options = [
    'http' => [
        'method' => 'POST',
        'header' => 'Content-Type: application/json',
        'content' => json_encode($data)
    ]
];

$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);
$result = json_decode($response, true);

if ($result['errcode'] == 0) {
    echo "添加客服账号成功";
} else {
    echo "添加客服账号失败，错误码：" . $result['errcode'] . "，错误信息：" . $result['errmsg'];
}
?>

Save the above code as the add_customer_service.php file and access the file in the browser to add a customer service account.

4. Send customer service messages

Once a customer service account is added, you can use PHP to send customer service messages to users. The following is an example of PHP code for sending customer service messages:

<?php
$openId = "user_openId";
$messageType = "text";
$content = "Hello, this is a test message.";

$url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=".$accessToken;

$data = [
    "touser" => $openId,
    "msgtype" => $messageType,
    $messageType => [
        "content" => $content
    ]
];

$options = [
    'http' => [
        'method' => 'POST',
        'header' => 'Content-Type: application/json',
        'content' => json_encode($data)
    ]
];

$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);
$result = json_decode($response, true);

if ($result['errcode'] == 0) {
    echo "发送客服消息成功";
} else {
    echo "发送客服消息失败，错误码：" . $result['errcode'] . "，错误信息：" . $result['errmsg'];
}
?>

Save the above code as send_customer_message.php file, and access the file in the browser to send customer service messages to the specified user.
