Java实现企业微信消息推送功能的详细步骤(企业微信消息推送api)

第一步:申请企业微信注册企业(链接:https://work.weixin.qq.com/nl/sem/registe?s=c&from=1011017189&bd_vid=11628667012427618020)

第二步:登录自己的企业微信找到应用管理———>添加应用

第三步:获取到应用的AgentId、Secret、企业id

第四步,准备代码编写:

model层代码:

package com.toone.itop.formula.function.inte.model;

/**

* @desc : 微信通用接口凭证

*

*/

public class AccessToken {

// 获取到的凭证

private String token;

// 凭证有效时间,单位:秒

private int expiresIn;

public String getToken() {

return token;

}

public void setToken(String token) {

this.token = token;

public int getExpiresIn() {

return expiresIn;

public void setExpiresIn(int expiresIn) {

this.expiresIn = expiresIn;

}

package com.toone.itop.formula.function.inte.model;

/**

* 消息基类(企业号 -> 普通用户)

*

*/

public class BaseMessage {

// 否 成员ID列表(消息接收者,多个接收者用‘|'分隔,最多支持1000个)。特殊情况:指定为@all,则向该企业应用的全部成员发送

private String touser;

// 否 部门ID列表,多个接收者用‘|'分隔,最多支持100个。当touser为@all时忽略本参数

private String toparty;

// 否 标签ID列表,多个接收者用‘|'分隔,最多支持100个。当touser为@all时忽略本参数

private String totag;

// 是 消息类型

private String msgtype;

// 是 企业应用的id,整型。可在应用的设置页面查看

private int agentid;

public String getTouser() {

return touser;

}

public void setTouser(String touser) {

this.touser = touser;

public String getToparty() {

return toparty;

public void setToparty(String toparty) {

this.toparty = toparty;

public String getTotag() {

return totag;

public void setTotag(String totag) {

this.totag = totag;

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;

}

package com.toone.itop.formula.function.inte.model;

/**

* 文本

*

*/

public class Text {

//是 消息内容,最长不超过2048个字节

private String content;

public String getContent() {

return content;

}

public void setContent(String content) {

this.content = content;

}

package com.toone.itop.formula.function.inte.model;

/**

* 文本消息

*

*/

public class TextMessage extends BaseMessage {

// 文本

private Text text;

// 否 表示是否是保密消息,0表示否,1表示是,默认0

private int safe;

public Text getText() {

return text;

}

public void setText(Text text2) {

this.text = text2;

}

public int getSafe() {

return safe;

}

public void setSafe(int safe) {

this.safe = safe;

}

}

通用工具类:

package com.toone.itop.formula.function.inte.util;

import java.security.cert.CertificateException;

import java.security.cert.X509Certificate;

import javax.net.ssl.X509TrustManager;

/**

* 证书信任管理器(用于https请求

*

*/

public class MyX509TrustManager implements X509TrustManager {

public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {

}

public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {

public X509Certificate[] getAcceptedIssuers() {

return null;

}

package com.toone.itop.formula.function.inte.util;

service层:

/**

* @param accessToken

* @param message

* void

*/

public static String sendMessage(String uid, String content) {

// 1.获取access_token:根据企业id和应用密钥获取access_token,并拼接请求url

String accessToken = WeChatUtil.getAccessToken(WeChatParamesUtil.corpId, WeChatParamesUtil.corpsecret).getToken();

// 2.获取发送对象,并转成json

Gson gson = new Gson();

TextMessage message = new TextMessage();

// 1.1非必需

message.setTouser(uid); // 不区分大小写

//message.setToparty("1");

//message.getTouser(totag);

// txtMsg.setSafe(0);

// 1.2必需

message.setMsgtype("text");

message.setAgentid(WeChatParamesUtil.agentId);

Text text = new Text();

text.setContent(content);

message.setText(text);

String jsonMessage = gson.toJson(message);

// 3.获取请求的url

String url = sendMessage_url.replace("ACCESS_TOKEN", accessToken);

// 4.调用接口,发送消息

JSONObject jsonObject = WeChatUtil.httpRequest(url, "POST", jsonMessage);

// 4.错误消息处理

if (null != jsonObject) {

if (0 != jsonObject.getInt("errcode")) {

System.out.println("消息发送失败 errcode:{} errmsg:{}" + jsonObject.getInt("errcode") + jsonObject.getString("errmsg"));

}

}

return jsonObject.toString();

}

public static void main(String[] args) {

// 0.设置消息内容

String content = "这是一条测试消息";

//userId为企业用户的id

String userId = "qianxia";

// 3.发送消息:调用业务类,发送消息
