Java實現(xiàn)企業(yè)微信消息推送功能的詳細步驟
第一步:申請企業(yè)微信注冊企業(yè)(鏈接:https://work.weixin.qq.com/nl/sem/registe?s=c&from=1011017189&bd_vid=11628667012427618020)
第二步:登錄自己的企業(yè)微信找到應用管理———>添加應用
第三步:獲取到應用的AgentId、Secret、企業(yè)id
第四步,準備代碼編寫:
model層代碼:
package com.toone.itop.formula.function.inte.model; /** * @desc : 微信通用接口憑證 * */ public class AccessToken { // 獲取到的憑證 private String token; // 憑證有效時間,單位: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; /** * 消息基類(企業(yè)號 -> 普通用戶) * */ public class BaseMessage { // 否 成員ID列表(消息接收者,多個接收者用‘|'分隔,最多支持1000個)。特殊情況:指定為@all,則向該企業(yè)應用的全部成員發(fā)送 private String touser; // 否 部門ID列表,多個接收者用‘|'分隔,最多支持100個。當touser為@all時忽略本參數(shù) private String toparty; // 否 標簽ID列表,多個接收者用‘|'分隔,最多支持100個。當touser為@all時忽略本參數(shù) private String totag; // 是 消息類型 private String msgtype; // 是 企業(yè)應用的id,整型??稍趹玫脑O置頁面查看 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 消息內容,最長不超過2048個字節(jié) 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,默認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; } }
通用工具類:
package com.toone.itop.formula.function.inte.util; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; import javax.net.ssl.X509TrustManager; /** * 證書信任管理器(用于https請求 * */ 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; /** * 企業(yè)微信參數(shù) * */ public class WeChatParamesUtil { // 1.微信參數(shù) // 企業(yè)ID public final static String corpId = "ww0b7de3b4c25ba7881"; // 企業(yè)應用私鑰OA public final static String corpsecret = "xbV7an7Mev8yqsnSzzzSn0L_cCnOTJxbo9gVZR7ObpY1"; // 企業(yè)應用的id public final static int agentId = 1000008; public final static String aws6url = "http://localhost:8088"; }

service層:
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 : 發(fā)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:發(fā)送消息 * @param accessToken * @param message * void */ public static String sendMessage(String uid, String content) { // 1.獲取access_token:根據(jù)企業(yè)id和應用密鑰獲取access_token,并拼接請求url String accessToken = WeChatUtil.getAccessToken(WeChatParamesUtil.corpId, WeChatParamesUtil.corpsecret).getToken(); // 2.獲取發(fā)送對象,并轉成json Gson gson = new Gson(); TextMessage message = new TextMessage(); // 1.1非必需 message.setTouser(uid); // 不區(qū)分大小寫 //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.獲取請求的url String url = sendMessage_url.replace("ACCESS_TOKEN", accessToken); // 4.調用接口,發(fā)送消息 JSONObject jsonObject = WeChatUtil.httpRequest(url, "POST", jsonMessage); // 4.錯誤消息處理 if (null != jsonObject) { if (0 != jsonObject.getInt("errcode")) { System.out.println("消息發(fā)送失敗 errcode:{} errmsg:{}" + jsonObject.getInt("errcode") + jsonObject.getString("errmsg")); } } return jsonObject.toString(); } public static void main(String[] args) { // 0.設置消息內容 String content = "這是一條測試消息"; //userId為企業(yè)用戶的id String userId = "qianxia"; // 3.發(fā)送消息:調用業(yè)務類,發(fā)送消息 WeChatService.sendMessage(userId, content); } }
