How to use Java language and Tencent Cloud API to implement SMS sending

1. Introduction
With the rapid development of the mobile Internet, SMS notifications have become an important communication method between enterprises and users. Tencent Cloud provides a powerful SMS API service that can help developers quickly implement SMS sending functions. This article will introduce how to use Java language to connect with Tencent Cloud API to implement the SMS sending function.

2. Preparation

1. Register Tencent Cloud account
2. Create SMS application
3. Get API key (SecretId and SecretKey)

3. Introduce dependencies
In Java projects, we can use Maven or Gradle to manage dependencies. Add the following dependencies to your project:

<dependency>
    <groupId>com.tencentcloudapi</groupId>
    <artifactId>tencentcloud-sdk-java</artifactId>
    <version>3.0.2</version>
</dependency>

4. Sample code
The following is a simple sample code that shows how to use the Java language to call the Tencent Cloud API to implement the SMS sending function. First, we need to create a SmsClient and then call the SendSms method to send text messages.

import com.tencentcloudapi.common.Credential;
import com.tencentcloudapi.common.profile.ClientProfile;
import com.tencentcloudapi.common.profile.HttpProfile;
import com.tencentcloudapi.sms.v20210111.SmsClient;
import com.tencentcloudapi.sms.v20210111.models.SendSmsRequest;
import com.tencentcloudapi.sms.v20210111.models.SendSmsResponse;

public class SmsSender {
    public static void main(String[] args) {
        // 设置密钥和地域信息
        Credential cred = new Credential("Your SecretId", "Your SecretKey");
        HttpProfile httpProfile = new HttpProfile();
        httpProfile.setEndpoint("sms.tencentcloudapi.com");
        ClientProfile clientProfile = new ClientProfile();
        clientProfile.setHttpProfile(httpProfile);

        // 实例化sms client对象
        SmsClient client = new SmsClient(cred, "ap-guangzhou", clientProfile);

        // 构造请求对象
        SendSmsRequest req = new SendSmsRequest();
        req.setSmsSdkAppid("Your SmsSdkAppid");
        req.setSign("Your Sign");
        req.setTemplateID("Your TemplateID");
        req.setPhoneNumberSet(new String[] { "Your PhoneNumber" });
        req.setTemplateParamSet(new String[] { "Your TemplateParam" });

        try {
            // 发送短信
            SendSmsResponse resp = client.SendSms(req);
            System.out.println(resp.getRequestId());
        } catch (Exception e) {
            System.out.println(e.toString());
        }
    }
}

In the code, you need to replace the following parts with your own information:

• Your SecretId: SecretId of the API key
• Your SecretKey: API key SecretKey
• Your SmsSdkAppid: Your SMS SDK Appid
• Your Sign: Your SMS signature
• Your TemplateID: Your SMS template ID
• Your PhoneNumber: The mobile phone number you want to send text messages to
• Your TemplateParam: Your text message template parameters

5. Running results
If everything goes well, you will be able to log in to the console See the return result of sending the text message, including the requested ID and other information.
