java调用企业微信接口发送消息

企业微信官网服务API地址：https://work.weixin.qq.com/api/doc/90001/90143/91201

1、注册企业微信
获取企业ID：在注册后：我的企业最下面


2、在应用管理

中创建应用

然后进入应用获取：应用id（agentID）和管理组的凭证秘钥【CorpSecret】=Secret

依赖：

com.google.code.gson
gson
2.8.2


org.apache.httpcomponents
httpclient
4.5.2



org.apache.httpcomponents
httpcore
4.4.5

用到的UrlData类和WeChatData

 import org.springframework.stereotype.Component;

@Component
public class UrlData {
//应用组织编号(企业ID)   corpsecret应用秘钥
String corpid;
 // corpsecret应用秘钥  管理组的凭证秘钥【CorpSecret】 用的 企业号/团队号 Secret
String corpsecret;
//获取ToKen的请求
String Get_Token_Url;
//发送消息的请求
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;
}

@Override
public String toString() {
    return "UrlData{" +
            "corpid='" + corpid + '\'' +
            ", corpsecret='" + corpsecret + '\'' +
            ", Get_Token_Url='" + Get_Token_Url + '\'' +
            ", SendMessage_Url='" + SendMessage_Url + '\'' +
            '}';
}
}

WeChatData 类

import org.springframework.stereotype.Component;

@Component
public class WeChatData {
//“微信消息发送”的post数据对象文件
//发送微信消息的URL
//    String sendMsgUrl="https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=";
//成员账号
String touser;
//消息类型
String msgtype;
//企业应用的agentID
int agentid;
//实际接收Map类型数据
Object text;

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;
}
}

get请求信息（请求地址可以参考官网）

import java.io.IOException;

/**

                   String data,String token) throws IOException {
    CloseableHttpClient httpclient = HttpClients.createDefault();
    httpPost = new HttpPost(url+token);

//获取企业微信标签下的成员

        for(int i=0;i useridkey = map.keySet();
    System.out.println(useridkey);
    return useridkey;
}
}

上面是获取token的方法和get请求，然后获取成员，下面是发送消息（文本格式的），群发和单独发送

 //传入文本格式的直接发送消息，这个是发送给部门所有人 ，这里部门ID 写死了
public void send_MsgDepartment(String Msg){
    Send_weChatMsg sw = new Send_weChatMsg();
    try {
 
        String agentId = Property.getProperty("AgentId");
        String token = sw.getToken(Property.getProperty("CorpID"),Property.getProperty("Secret"));
        Set departmentData = sw.getDepartmentData(token, 1, 0);
        for (String departmentDatum : departmentData) {
            String name=departmentDatum;
            String postdata = sw.createpostdata(name, "text", Integer.parseInt(agentId), "content",Msg);
            String resp = sw.post("utf-8", Send_weChatMsg.CONTENT_TYPE,(new UrlData()).getSendMessage_Url(), postdata, token);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

//单独输入信息发送,这个是发送给人（配置文件里面配置的人员）
public void send_Msgpersonnel(String Information){
    Send_weChatMsg sw = new Send_weChatMsg();
    try {
   
        String agentId = Property.getProperty("AgentId");
        String token = sw.getToken(Property.getProperty("CorpID"),Property.getProperty("Secret"));
        String userName = Property.getProperty("UserName");
        String[] split = userName.split(",");
        for (int i=0;i tagsData = sw.getTagsData(token, Integer.parseInt(tags));
        for (String departmentDatum : tagsData) {
            String name=departmentDatum;
            String postdata = sw.createpostdata(name, "text", Integer.parseInt(agentId), "content",Msg);
            String resp = sw.post("utf-8", Send_weChatMsg.CONTENT_TYPE,(new UrlData()).getSendMessage_Url(), postdata, token);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

以上是完整版的java对企业微信发送消息
