Java实现短信发送_java发送短信-程序员宅基地

首先，我们要实现Java短信发送功能需要去申请第三方短信接口，以阿里云为例
点击跳转

在API市场中找到短信验证码接口：

我们可以先选择免费试用来测试：

点击立即购买后可前往控制台查看：

OK，一切就绪后我们开始测试使用。
首先我们先回到商品详情页，在商品详情页下面，说明了这个接口的调用地址以及请求参数等：

接下来我们通过实例来调用接口进行测试：
1、加入相关依赖
具体可参考：相关依赖

		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>fastjson</artifactId>
			<version>1.2.15</version>
		</dependency>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>

            <version>4.5</version>
            <scope>test</scope>
        </dependency>

2、创建HttpUtils.java类

}

3、发送验证码

public static void main(String[] args) {
    
        //短信api调用地址
        String host = "https://dfsns.market.alicloudapi.com";
        //请求路径
        String path = "/data/send_sms";
        //请求方式
        String method = "POST";
        //appcode：自己的AppCode，可以在自己的控制台找到，是一串32位的字符串
        String appcode = "14xfa0523x3s2fe8ep0u54te14c2w36ad";
        Map<String, String> headers = new HashMap<String, String>();
        //最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
        headers.put("Authorization", "APPCODE " + appcode);
        //根据API的要求，定义相对应的Content-Type
        headers.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
        Map<String, String> querys = new HashMap<String, String>();
        Map<String, String> bodys = new HashMap<String, String>();

        //使用随机数生成4位验证码
        StringBuilder stringBuilder = new StringBuilder();
        for (int i = 0; i < 4; i++) {
    
            int randomNum = (int) (Math.random()*10);
            stringBuilder.append(randomNum);
        }
        String code = stringBuilder.toString();
        //这里是要发送给用户的验证码，我们使用了随机数进行生成
        bodys.put("content", "code:"+code);
        //这里是接受短信的手机号码，我们在实际开发时这里就不能写死了
        bodys.put("phone_number", "176****5321");
        //这里是发送短信的模板ID：代表整体短信文案模板
        bodys.put("template_id", "TPL_0000");
        try {
    
            HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);
            System.out.println(response.toString());
            //获取response的body
            System.out.println(EntityUtils.toString(response.getEntity()));
        } catch (Exception e) {
    
            e.printStackTrace();
        }
    }

好的大功告成，我们可以看下控制台给我们的打印：

说明发送成功了。我们打开手机也可以看到发给我们的验证码
手机收到
