PHP calls Dingxintong SMS interface to send SMS messages

In recent years, with the development of mobile Internet, text messaging has become an important tool for people to communicate. How to quickly send text messages is particularly important for enterprises. This article will introduce how to use PHP language to call Dingxintong SMS interface to realize automatic sending of SMS.

1. Register a Dingxintong account and obtain the API interface key

Before using the Dingxintong SMS interface, we need to register an account on the Dingxintong official website. After the registration is completed, we need to obtain our own API interface key in "API Management".

2. Install related PHP extensions

We need to install the curl extension and openssl extension. These two extensions are necessary for PHP to call the https interface. You can install it through the following command:

sudo apt-get install php-curl php-openssl

3. Write PHP code

Next, we can start writing PHP code! The following is a simple example:

<?php
// 鼎信通短信接口地址
$url = 'https://www.dingxintong.cn/Api/Message/SendMessage';

// 需要发送短信的手机号码
$mobiles = '13800138000,13900139000';

// 用户名和密码
$username = 'your_username';
$password = 'your_password';

// 短信内容，注意中文需要进行urlencode编码
$content = urlencode('您的验证码为1234，请勿泄漏。');

// 参数数组
$params = array(
    'username' => $username,
    'password' => $password,
    'mobiles' => $mobiles,
    'content' => $content
);

// 使用curl发送post请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);

// 输出结果
echo $result;
?>

4. Test SMS sending

Before running the PHP code, we need to ensure that there is enough SMS balance in the Ding Xintong account. If the balance is insufficient, text messages cannot be sent.

We can run the PHP code directly in the terminal to test SMS sending. Enter the following command in the terminal:

php test.php

If everything is normal, we can receive a text message.

5. Notes

1. In order to ensure the success rate and security of text messages, we need to authenticate through Dingxintong’s API interface before sending each text message;
2. When using the urlencode function to encode Chinese characters, you need to pay attention to the encoded length. In Dingxintong’s SMS interface, the length of a text message is limited to 70 characters (that is, the length of a Chinese character is 2);
3. When sending text messages, we need to pay attention to the sending rate of text messages. If it is too fast, Frequent transmissions may be intercepted by the SMS platform.

Summary:

Using PHP language to call Dingxintong SMS interface can easily realize the automatic sending of SMS. In actual use, we need to pay attention to issues such as the encoding, authentication, and sending rate of text messages to ensure the success rate and security of text messages.
