java实现企业微信消息推送功能的详细步骤-mile米乐体育
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; /** * 企业微信参数 * */ public class wechatparamesutil { // 1.微信参数 // 企业id public final static string corpid = "ww0b7de3b4c25ba7881"; // 企业应用私钥oa public final static string corpsecret = "xbv7an7mev8yqsnszzzsn0l_ccnotjxbo9gvzr7obpy1"; // 企业应用的id public final static int agentid = 1000008; public final static string aws6url = "http://localhost:8088"; }

service层:
package com.toone.itop.formula.function.inte.service; import net.sf.json.jsonobject; import com.google.gson.gson; import com.toone.itop.formula.function.inte.model.text; import com.toone.itop.formula.function.inte.model.textmessage; import com.toone.itop.formula.function.inte.util.wechatparamesutil; import com.toone.itop.formula.function.inte.util.wechatutil; /** * @desc : 发送消息 * */ public class wechatservice { private static string sendmessage_url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=access_token"; /** * @desc :0.公共方法:发送消息 * @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 wechatservice.sendmessage(userid, content); } }
