javaweb如何使用华为云短信通知公共类调用

javaweb华为云短信通知公共类调用

情景:公司业务需求,短信从阿里云切换到华为云,参照华为云短信调用的相关文档遇到不少坑,在此记录一下。

开发环境:JDK1.8 系统环境:SpringBoot

1、华为云短信配置信息在application.yml中配置

sms:

huawei:

url: https://rtcsms.cn-north-1.myhuaweicloud.com:10743/sms/batchSendSms/v1

appKey: ******

appSecret: ******

2、创建短信公共类:HwSmsSender

System.out.println(entity);

HwSmsRoot hwSmsRoot = JSONObject.parseObject(entity, HwSmsRoot.class);

System.out.println(hwSmsRoot.getCode());

}

}

3、上面公共类还用到以下类:

HwSmsResult

import lombok.Data;

@Data

public class HwSmsResult {

private String originTo;

private String createTime;

private String from;

private String smsMsgId;

private String status;

}

HwSmsRoot

@Data

public class HwSmsRoot {

private List result;

private String code;

private String description;

}

SmsConstants

public class SmsConstants {

public static class ResultMessage {

/**

* 通道 美团外卖 验证码类

*/

public static String SIGN_NOTIFY_ID = "8821041535507";

public static String SMS_SEND_ID = "8fed7b85f85d4a248fe983a321";

}

}

LoggerUtils

import org.slf4j.Logger;

public class LoggerUtils {

public static void debug(Logger logger, Object message) {

if (logger.isDebugEnabled()) {

logger.debug("Debug日志信息{}", message);

}

}

public static void info(Logger logger, Object message) {

if (logger.isInfoEnabled()) {

logger.info("Info日志信息{}", message);

}

}

public static void error(Logger logger, Object message) {

if (logger.isErrorEnabled()) {

logger.error("Error日志信息{}", message);

}

}

}

4、实战调用如下:

/**

* 获取验证码接口

*/

@PostMapping("/sendMessageWxUser")

public AjaxResult sendMessageWxUser(@RequestBody WxUser user, HttpServletRequest request, HttpServletResponse response) throws Exception {

String ipAddr = IPUtils.getIpAddr(request);

AjaxResult ajaxResult = new AjaxResult(0, "短信发送成功!请等待查收!");

if (StringUtils.isEmpty(user.getLoginName())) {

return AjaxResult.error(500, "手机号不能为空");

}

//生成6位随机数,有效期1分钟

String randNum = VerificatieCodeUtils.getRandNum(6);

String[] templateParas = new String[]{randNum, "1"};

String templateId = SmsConstants.ResultMessage.SMS_SEND_ID;

String code = smsSendUtils.sendRegisterSMS(user.getLoginName(), templateId, JSONObject.toJSONString(templateParas));

logger.info("--打印验证码:" + randNum);

if ("0".equals(code)) {

//缓存按ip+varcode 作为key保存

redisCache.setCacheObject(ipAddr + "varcode", randNum, 60, TimeUnit.SECONDS);

return ajaxResult;

} else {

return new AjaxResult(500, "短信发送失败!");

}

}

VerificatieCodeUtils :验证码随机数生成

import java.util.Random;

public class VerificatieCodeUtils {

public static String getRandNum(int charCount) {

String charValue = "";

for (int i = 0; i < charCount; i++) {

char c = (char) (randomInt(0, 10) + '0');

charValue += String.valueOf(c);

}

return charValue;

}

public static int randomInt(int from, int to) {

Random r = new Random();

return from + r.nextInt(to - from);

}

}

最后:需要注意的是,根据自己项目开发环境版本调整一些相关方法,以及华为云一些密钥什么需要填写正确。

java调用华为云上的文字识别(OCR)接口

首先要满足的条件,已注册华为云账户,并订阅华为云上的文字识别接口,以下以订阅的身份证识别接口为例

package OCRDemo;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.PrintWriter;

import java.net.URL;

import java.net.URLConnection;

import java.util.List;

import java.util.Map;

/**

* @author abang

* @date 2020/7/3 0003 20:59

*/

public class GetOCR {

public static void main(String[] args) throws IOException {

//请求的region

String region = "cn-north-4";

//用户名

String username = "xxxxxx";

//用户密码

String password = "xxxxxx";

//账户名

String userName = "xxxxxx";

//请求的uri接口

String uri = "/v1.0/ocr/id-card";

//传入image或uri的json字符串(图片为公网的地址,可查询)

String param = "{\"url\":\"http://photocdn.sohu.com/20101021/Img276166786.jpg\"}";

//获取用token

String token = getToken(region,username,password,userName);

//返回请求的图片文字信息

System.out.println(getIdCard(region,token,param,uri));

}

//获取请求链接中用户的token信息

public static String getToken(String region,String username,String password,String userName) throws IOException {

String iam = "https://iam."+region+".myhuaweicloud.com/v3/auth/tokens";

String param = "{\"auth\":{\"identity\":{\"methods\":[\"password\"],\"password\":{\"user\":{\"name\":\"" + username + "\",\"password\":\"" + password + "\",\"domain\":{\"name\":\"" + userName + "\"}}}},\"scope\":{\"project\":{\"name\":\"cn-north-4\"}}}}";

PrintWriter out;

BufferedReader in = null;

String token = "";

String response = "";

try {

//需要请求的url

URL url = new URL(iam);

//打开和URL之间的连接

URLConnection connection = url.openConnection();

//设置通用的请求属性,请求头部分

connection.setRequestProperty("accept", "*/*");

connection.setRequestProperty("connection", "Keep-Alive");

connection.setRequestProperty("user-agent", "Mozilla/4.0");

// 发送POST请求必须设置如下两行

connection.setDoInput(true);

connection.setDoOutput(true);

// 建立实际的连接

connection.connect();

///获取URLConnection对象对应的输出流

out = new PrintWriter(connection.getOutputStream());

//发送请求参数

out.write(param);

//flush输出流的缓冲

out.flush();

//获取相应头中的token信息

token = connection.getHeaderField("X-Subject-Token");

//定义BufferedReader输入流来读取URL的响应

in = new BufferedReader(new InputStreamReader(connection.getInputStream()));

String line;

while ((line = in.readLine()) != null) {

//换行打印获取结果

response += "\n" + line;

}

// 获取所有响应头字段

Map> map = connection.getHeaderFields();

// 遍历所有的响应头字段

for (String key : map.keySet()) {

//打印出相应头中的信息

//System.out.println(key + "--->" + map.get(key));

}

} catch (Exception e) {

System.out.println("发送GET请求出现异常!" + e);

e.printStackTrace();

}

// 使用finally块来关闭输入流

finally {

try {

if (in != null) {

in.close();

}

} catch (Exception e2) {

e2.printStackTrace();

}

}

//返回所要用到的token信息

return token;

}

//请求云上接口,调用接口服务

public static String getIdCard(String region,String token,String param,String uri) throws IOException {

StriiQrQYng ocr = "https://ocr."+region+".myhuaweicloud.com"+uri;

String response = "";

BufferedReader in = null;

try {

URL url = new URL(ocr);

URLConnection connection = url.openConnection();

//容易载跟头,表明请求体的部分为json形式

connection.setRequestProperty("Content-Type", "application/json");

connection.setRequestProperty("X-Auth-Token", token);

connection.setDoOutput(true);

connection.setDoInput(true);

connection.connect();

PrintWriter out = new PrintWriter(connection.getOutputStream());

out.write(param);

out.flush();

in = new BufferedReader(new InputStreamReader(connection.getInputStream()));

String line;

while ((line = in.readLine()) != null) {

response += "\n" + line;

}

} catch (Exception e) {

System.out.println("发送GET请求出现异常!" + e);

e.printStackTrace();

}

// 使用finally块来关闭输入流

finally {

try {

if (in != null) {

in.close();

}

} catch (Exception e2) {

e2.printStackTrace();

}

}

//返回相应体中的结果,打印出来

return response;

}

}

返回成功
