一:创建短信签名和模板

二:创建AccessKey,来使用API

三:使用短信API

四:接下来只需要按照官方文档复制代码就可以运行项目了

核心代码:

导入jar包

<dependency>
  <groupId>com.aliyun</groupId>
  <artifactId>aliyun-java-sdk-core</artifactId>
  <version>4.5.16</version>
</dependency>

官网代码

import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;

public class SendSms {
    public static void main(String[] args) {
        DefaultProfile profile = DefaultProfile.getProfile("ap-northeast-1", "<accessKeyId>", "<accessSecret>");
        IAcsClient client = new DefaultAcsClient(profile);

        CommonRequest request = new CommonRequest();
        request.setSysMethod(MethodType.POST);
        request.setSysDomain("dysmsapi.ap-southeast-1.aliyuncs.com");
        request.setSysVersion("2017-05-25");
        request.setSysAction("SendSms");
        request.putQueryParameter("PhoneNumbers", "1503871****");
        request.putQueryParameter("SignName", "阿里大于测试专用");
        request.putQueryParameter("TemplateCode", "SMS_209335004");
        request.putQueryParameter("TemplateParam", "{\"code\":\"1111\"}");
        try {
            CommonResponse response = client.getCommonResponse(request);
            System.out.println(response.getData());
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}

用官网的代码报错

com.aliyuncs.exceptions.ServerException: ServiceUnavailable : The request has failed due to a temporary failure of the server.
RequestId : CF12905D-C736-47B2-9D20-A85C04EBF852
    at com.aliyuncs.DefaultAcsClient.getCommonResponse(DefaultAcsClient.java:176)
    at cn.itcast.duanxin.SendMsg.main(SendMsg.java:32)

将官网这些代码改成下面的

request.setSysDomain("dysmsapi.aliyuncs.com");

package cn.itcast.duanxin;
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;

import java.util.UUID;

public class SendMsg {
    public static void main(String[] args) {
        DefaultProfile profile = DefaultProfile.getProfile("ap-northeast-1", "===", "===");
        IAcsClient client = new DefaultAcsClient(profile);

        CommonRequest request = new CommonRequest();
        request.setSysMethod(MethodType.POST);
        request.setSysDomain("dysmsapi.aliyuncs.com");
        request.setSysVersion("2017-05-25");
        request.setSysAction("SendSms");
        String phone="===";
        request.putQueryParameter("PhoneNumbers", phone);
        request.putQueryParameter("SignName", "===");
        request.putQueryParameter("TemplateCode", "====");
        String msg= UUID.randomUUID().toString().replace("-","").substring(0,6);
        request.putQueryParameter("TemplateParam", "{\"code\":\""+msg+"\"}");
        try {
            CommonResponse response = client.getCommonResponse(request);
            System.out.println(response.getData());
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}
