网易云发送短信验证码java实现
首先，登陆网易云信注册账号然后获取自己的App Key与App Secret，这里就不多说了，可以自行百度。
然后进入如下界面https://www.163yun.com/help/documents/33716973365022720#API%E8%B0%83%E7%94%A8%E8%AF%B4%E6%98%8E
在服务端API中我们可以很容易的找到这段代码，这是用来加密用的（关于如何加密也可以找到）
import java.security.MessageDigest;
public class CheckSumBuilder {
// 计算并获取CheckSum
public static String getCheckSum(String appSecret, String nonce, String curTime) {
return encode("sha1", appSecret + nonce + curTime);
}
// 计算并获取md5值
public static String getMD5(String requestBody) {
return encode(“md5”, requestBody);
}
private static String encode(String algorithm, String value) {
if (value == null) {
return null;
}
try {
MessageDigest messageDigest
= MessageDigest.getInstance(algorithm);
messageDigest.update(value.getBytes());
return getFormattedText(messageDigest.digest());
} catch (Exception e) {
throw new RuntimeException(e);
}
}
private static String getFormattedText(byte[] bytes) {
int len = bytes.length;
StringBuilder buf = new StringBuilder(len * 2);
for (int j = 0; j < len; j++) {
buf.append(HEX_DIGITS[(bytes[j] >> 4) & 0x0f]);
buf.append(HEX_DIGITS[bytes[j] & 0x0f]);
}
return buf.toString();
}
private static final char[] HEX_DIGITS = { '0', '1', '2', '3', '4', '5',
'6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f' };
}
接着在下面我们又可以找到这段模板代码，我们先看他的模板，具体信息可以参考手册然后了解它们的意义
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
public class Test {
public static void main(String[] args) throws Exception{
DefaultHttpClient httpClient = new DefaultHttpClient();
String url = "https://api.netease.im/nimserver/user/create.action";
HttpPost httpPost = new HttpPost(url);
String appKey = "94kid09c9ig9k1loimjg012345123456";
String appSecret = "123456789012";
String nonce = "12345";
String curTime = String.valueOf((new Date()).getTime() / 1000L);
String checkSum = CheckSumBuilder.getCheckSum(appSecret, nonce ,curTime);//参考 计算CheckSum的java代码
// 设置请求的header
httpPost.addHeader("AppKey", appKey);
httpPost.addHeader("Nonce", nonce);
httpPost.addHeader("CurTime", curTime);
httpPost.addHeader("CheckSum", checkSum);
httpPost.addHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");
// 设置请求的参数
List nvps = new ArrayList();
nvps.add(new BasicNameValuePair("accid", "helloworld"));
httpPost.setEntity(new UrlEncodedFormEntity(nvps, "utf-8"));
// 执行请求
HttpResponse response = httpClient.execute(httpPost);
// 打印执行结果
System.out.println(EntityUtils.toString(response.getEntity(), "utf-8"));
}
} 
然后咱们把上面的代码稍作修改变成如下的样子
package tool;
import com.alibaba.fastjson.JSON;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class SMSUtils {
private static final String NONCE = "123456";
private static final String APP_SECRET = "你自己登陆所获取的";
private static final String APP_KEY = "你自己登陆所获取的";
/**

*/
public static final boolean sendCode(String mobile, String templateId) throws IOException {
HttpPost httpPost = new HttpPost("https://api.netease.im/sms/sendcode.action");
String currentTime = String.valueOf(new Date().getTime()/1000L);
String checkSum = CheckSumBuilder.getCheckSum(APP_SECRET,NONCE,currentTime);
//set header
httpPost.setHeader("AppKey",APP_KEY);
httpPost.setHeader("CurTime",currentTime);
httpPost.setHeader("Nonce",NONCE);
httpPost.setHeader("CheckSum",checkSum);
httpPost.setHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8");
//set data

nameValuePairList.add(new BasicNameValuePair("mobile",mobile));

httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairList,"utf-8"));
//start request
CloseableHttpClient closeableHttpClient = HttpClients.createDefault();
HttpResponse httpResponse = closeableHttpClient.execute(httpPost);
String responseResult = EntityUtils.toString(httpResponse.getEntity(),"utf-8");
System.out.println("responseResult:"+responseResult);
String stateCode = JSON.parseObject(responseResult).getString("code");
if(stateCode.equals("200")){
return true;
}
return false;
}
/**

*
* @param mobile 电话号码
* @param code 发送到mobile上的短信
*/
public static final boolean verifyCode(String mobile, String code) throws IOException {
HttpPost httpPost = new HttpPost("https://api.netease.im/sms/verifycode.action");
String currentTime = String.valueOf(new Date().getTime()/1000L);
String checkSum = CheckSumBuilder.getCheckSum(APP_SECRET,NONCE,currentTime);
//set header
httpPost.setHeader("AppKey",APP_KEY);
httpPost.setHeader("CurTime",currentTime);
httpPost.setHeader("Nonce",NONCE);
httpPost.setHeader("CheckSum",checkSum);
httpPost.setHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8");
//set data
List nameValuePairList = new ArrayList();
nameValuePairList.add(new BasicNameValuePair("code",code));
nameValuePairList.add(new BasicNameValuePair("mobile",mobile));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairList,"utf-8"));
//start request
CloseableHttpClient closeableHttpClient = HttpClients.createDefault();
HttpResponse httpResponse = closeableHttpClient.execute(httpPost);
String responseResult = EntityUtils.toString(httpResponse.getEntity(),"utf-8");
System.out.println("responseResult:"+responseResult);
String stateCode = JSON.parseObject(responseResult).getString("code");
if(stateCode.equals("200")){
return true;
}
return false;
}
} 接下来就是测试了，我们来一个简单的代码来试一试
import java.io.IOException;
import java.util.Scanner;
import tool.SMSUtils;
public class Test1 {
private static String mobile = "你需要发送短信的手机号";
public static void main(String[] args) {
try {
SMSUtils.sendCode(mobile, "模板号（在里面有你自己设置的发送格式）");
} catch (IOException e) {
e.printStackTrace();
}
Scanner scanner = new Scanner(System.in);
System.out.println("请输入你收到的验证码");
String code = scanner.nextLine();
try {
if(SMSUtils.verifyCode(mobile, code)) {
System.out.println("校验成功");
}else {
System.out.println("校验失败");
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
一番操作下来之后就大功告成了，下面我们结合web来一起试一下（运用了一点点异步），有关于这异步，不知道的可以稍微去看看，不会用太多时间的
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
接下来是俩个Servlet
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import tool.SMSUtils;
public class SendcodeServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
private static String templateId = "4003516";
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String mobile = request.getParameter("mobile");
System.out.println(mobile);
SMSUtils.sendCode(mobile, templateId);
}
}
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import tool.SMSUtils;
public class CheckcodeServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String code = request.getParameter("code");//用户输入的验证码
String mobile = request.getParameter("mobile");
System.out.println(code);
if(SMSUtils.verifyCode(mobile,code)) {
System.out.println("成功");
//验证成功跳转到成功界面
request.getRequestDispatcher("success.jsp").forward(request, response);
}else {
System.out.println("失败");
}
}
}
不过在这里我有一个疑问就是最后验证出来是成功，也打印了出来，但是那个跳转界面不知道为什么没有出现，然而到这时候我的短信已经全部发送完了，没有剩余的存货了，有点尴尬。。。。。。先留个坑，或许之后写类似的项目的时候我就知道了。
我觉得实现这种功能比较重要的一点就是学会去看开发者API，里面有各种介绍，还有好多东西我也没怎么看，但单单看这俩种就能实现验证码的发送与校验了。
