Java实现短信发送
短信预约 -IT技能 免费直播动态提醒
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

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.alibabagroupId><artifactId>fastjsonartifactId><version>1.2.15version>dependency> <dependency> <groupId>org.apache.httpcomponentsgroupId> <artifactId>httpclientartifactId> <version>4.2.1version> dependency> <dependency> <groupId>org.apache.httpcomponentsgroupId> <artifactId>httpcoreartifactId> <version>4.2.1version> dependency> <dependency> <groupId>commons-langgroupId> <artifactId>commons-langartifactId> <version>2.6version> dependency> <dependency> <groupId>org.eclipse.jettygroupId> <artifactId>jetty-utilartifactId> <version>9.3.7.v20160115version> dependency> <dependency> <groupId>junitgroupId> <artifactId>junitartifactId> <version>4.5version> <scope>testscope> dependency>2、创建HttpUtils.java类
HttpUtils.java类官方也已经帮我们封装好了，我们可以直接前往github下载,点击跳转
这里就直接把代码放上了

SchemeRegistry registry = ccm.getSchemeRegistry(); registry.register(new Scheme("https", 443, ssf)); } catch (KeyManagementException ex) { throw new RuntimeException(ex); } catch (NoSuchAlgorithmException ex) { throw new RuntimeException(ex); } }}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
