JAVA实现接入企业微信报警
引言
原来系统中报警采用短信和邮件方式，短信采用阿里的短信，近期由于 一些原因，项目中想将报警信息发送到 企业微信中，由于之前小编玩zabbix的时候实现过这个需求，所以认为通过java应该比较简单， 下面分享接入代码，直接上干货。
一、创建应用
1）、登录企业微信后台管理页面，选择应用管理
2）、在最下面 创建应用
这里面可以控制那些人收到报警信息，其中质量的Secret 就是我们后面代码中的秘钥；
3）获得企业id
在 管理后台-》我的企业 一栏的最下面可以找到企业ID
二、代码实现
添看到依赖
org.apache.httpcomponents
httpcore
4.4.6
org.apache.httpcomponents
httpclient
4.5.5
代码实现
1、实体类
package com.jack.common.utils;
/**
* @Description:
* @author: zhenghao
* @date: 2020/3/5 17:24
*/
public class IacsUrlDataVo {
String corpid;
String corpsecret;
String Get_Token_Url;
String SendMessage_Url;
public String getCorpid() {
return corpid;
}
public void setCorpid(String corpid) {
this.corpid = corpid;
}
public String getCorpsecret() {
return corpsecret;
}
public void setCorpsecret(String corpsecret) {
this.corpsecret = corpsecret;
}
public void setGet_Token_Url(String corpid,String corpsecret) {
this.Get_Token_Url ="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid="+corpid+"&corpsecret="+corpsecret;
}
public String getGet_Token_Url() {
return Get_Token_Url;
}
public String getSendMessage_Url(){
SendMessage_Url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=";
return SendMessage_Url;
}
}
package com.jack.common.utils;
/**
* @Description:
* @author: zhenghao
* @date: 2020/3/5 17:24
*/
public class IacsWeChatDataVo {
String touser;
String msgtype;
int agentid;
Object text;//实际接收Map类型数据
public Object getText() {
return text;
}
public void setText(Object text) {
this.text = text;
}
public String getMsgtype() {
return msgtype;
}
public void setMsgtype(String msgtype) {
this.msgtype = msgtype;
}
public int getAgentid() {
return agentid;
}
public void setAgentid(int agentid) {
this.agentid = agentid;
}
public String getTouser() {
return touser;
}
public void setTouser(String touser) {
this.touser = touser;
}
}
2、消息发送代码
package com.jack.common.utils;
import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.*;
/**
* @Description: 企业微信发送代码
* @author: zhenghao
* @date: 2020/3/5 17:25
*/
public class SendWeChatUtils {
private CloseableHttpClient httpClient;
private static HttpPost httpPost;//用于提交登陆数据
private static HttpGet httpGet;//用于获得登录后的页面
public static final String CONTENT_TYPE = "Content-Type";
static SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
private static Gson gson = new Gson();
/**
* 微信授权请求，GET类型，获取授权响应，用于其他方法截取token
*
* @param Get_Token_Url
* @return String 授权响应内容
* @throws IOException
*/
public String toAuth(String Get_Token_Url) throws IOException {
httpClient = HttpClients.createDefault();
httpGet = new HttpGet(Get_Token_Url);
CloseableHttpResponse response = httpClient.execute(httpGet);
String resp;
try {
HttpEntity entity = response.getEntity();
resp = EntityUtils.toString(entity, "utf-8");
EntityUtils.consume(entity);
} finally {
response.close();
}
LoggerFactory.getLogger(getClass()).info(" resp:{}", resp);
return resp;
}
/**
* 获取toAuth(String Get_Token_Url)返回结果中键值对中access_token键的值
*
* @param corpid 应用组织编号 corpsecret 应用秘钥
*/
public static String getToken(String corpid, String corpsecret) throws IOException {
SendWeChatUtils sw = new SendWeChatUtils();
IacsUrlDataVo uData = new IacsUrlDataVo();
uData.setGet_Token_Url(corpid, corpsecret);
String resp = sw.toAuth(uData.getGet_Token_Url());
Map map = gson.fromJson(resp,
new TypeToken>() {
}.getType());
return map.get("access_token").toString();
}
/**
* @param touser 发送消息接收者 ，msgtype消息类型（文本/图片等），
* @param application_id 应用编号。
* @return String
* @Title:创建微信发送请求post数据
*/
public static String createpostdata(String touser, String msgtype,
int application_id, String contentKey, String contentValue) {
IacsWeChatDataVo wcd = new IacsWeChatDataVo();
wcd.setTouser(touser);
wcd.setAgentid(application_id);
wcd.setMsgtype(msgtype);
Map content = new HashMap();
content.put(contentKey, contentValue + "\n--------\n" + df.format(new Date()));
wcd.setText(content);
return gson.toJson(wcd);
}
/**
* @param charset 消息编码 ，contentType 消息体内容类型，
* @param url 微信消息发送请求地址，data为post数据，token鉴权token
* @return String
* @Title 创建微信发送请求post实体
*/
public static String post(String charset, String contentType, String url,
String data, String token) throws IOException {
CloseableHttpClient httpclient = HttpClients.createDefault();
httpPost = new HttpPost(url + token);
httpPost.setHeader(CONTENT_TYPE, contentType);
httpPost.setEntity(new StringEntity(data, charset));
CloseableHttpResponse response = httpclient.execute(httpPost);
String resp;
try {
HttpEntity entity = response.getEntity();
resp = EntityUtils.toString(entity, charset);
EntityUtils.consume(entity);
} finally {
response.close();
}
LoggerFactory.getLogger(SendWeChatUtils.class).info(
"call [{}], param:{}, resp:{}", url, data, resp);
return resp;
}
public static void sendMsg(String strContent){
try {
String token = getToken("企业id", "秘钥");
String postdata = createpostdata("@all", "text", 1000011, "content",strContent);
String resp = post("utf-8", "text", (new IacsUrlDataVo()).getSendMessage_Url(), postdata, token);
// System.out.println("获取到的token======>" + token);
// System.out.println("请求数据======>" + postdata);
// System.out.println("发送微信的响应数据======>" + resp);
} catch (Exception e) {
e.printStackTrace();
}
}
}
上面代码中我们需要填写我们自己的企业id和秘钥；
3、业务调用
如需发送其他类型信息，附参考文档
