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


package com.seeker.common.utils.hwsms;

        //请求Body,不携带签名名称时,signature请填null
        String body = buildRequestBody(sender, receiver, templateId, templateParas, statusCallBack, signature);
        if (null == body || body.isEmpty()) {
            System.out.println("body is null.");
            return;
        }
 
        //请求Headers中的X-WSSE参数值
        String wsseHeader = buildWsseHeader(appKey, appSecret);
        if (null == wsseHeader || wsseHeader.isEmpty()) {
            System.out.println("wsse header is null.");
            return;
        }
 
        //如果JDK版本低于1.8,可使用如下代码
        //为防止因HTTPS证书认证失败造成API调用失败,需要先忽略证书信任问题
        //CloseableHttpClient client = HttpClients.custom()
        //        .setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
        //            @Override
        //            public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
        //                return true;
        //            }
        //        }).build()).setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE).build();
 
        //如果JDK版本是1.8,可使用如下代码
        //为防止因HTTPS证书认证失败造成API调用失败,需要先忽略证书信任问题
        CloseableHttpClient client = HttpClients.custom()
                .setSSLContext(new SSLContextBuilder().loadTrustMaterial(null,
                        (x509CertChain, authType) -> true).build())
                .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                .build();
 
        //请求方法POST
        HttpResponse response = client.execute(RequestBuilder.create("POST")
                .setUri(url)
                .addHeader(HttpHeaders.CONTENT_TYPE, "application/x-www-form-urlencoded")
                .addHeader(HttpHeaders.AUTHORIZATION, AUTH_HEADER_VALUE)
                .addHeader("X-WSSE", wsseHeader)
                .setEntity(new StringEntity(body)).build());
 
        //打印响应头域信息
        System.out.println(response.toString());
        //打印响应消息实体
        String entity = EntityUtils.toString(response.getEntity());
        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<HwSmsResult> result;
    private String code;
    private String description;
}

SmsConstants


public class SmsConstants {
    public static class ResultMessage {
        
        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：


 
    @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;

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";

            // 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<String, List<String>> 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 {
        String ocr = "https://ocr."+region+".myhuaweicloud.com"+uri;
        String response = "";
