spingboot调用企业微信应用推送api推送消息

 

//推送消息
public static String sendMessage(){
//String token =getAccessToken();
String token ="6qK5a5k07UXGDt6jt5KAmn5jhaU-GferPBWUdalHafRXGWpBHTtpJIBSR-LgnaiPpNKBAruhEUPhyMdemC7TyyzWgf2bb5vCze-b-fN3JogpPvIAz30mnVUj1Roo6Wxv78_JXB0Ii3OU8PmoInYOA8Q91Pl_UKqHoZV0KCFdZExtb84KFdNavoQGkRZXZzbRZZneZxLQOgxgvP0QT51PYA";
String userId="107944";//推送给具体某个人的userid
String departmentId="";
//String msgtype="mytext";
String agentid=WxConstants.AGENTID;//WxConstants.AGENTID是应用的agenid
String content="测试消息推送：你的快递已到，请携带工卡前往邮件中心领取。\n出发前可查看<a href=\"http://work.weixin.qq.com\">邮件中心视频实况</a>，聪明避开排队。";

JSONObject params = new JSONObject();
params.put("touser", userId);
// params.put("toparty", departmentId);
params.put("agentid", agentid);
JSONObject mytext = new JSONObject();
mytext.put("content",content);
params.put("msgtype", "text");
params.put("text",mytext);

try {
String aa=HttpUtils.httpPostMethod(WxConstants.POST_SEND_MESSAGE_UR + "?access_token=" + token, new HashMap<>(), params.toJSONString());
log.info("1.推送消息请求微信接口=="+aa);
log.info("2.推送消息请求微信接口=="+JSON.toJSONString(aa));
return aa;
} catch (IOException e) {
e.printStackTrace();
}
return null;
}

发送的是文本消息，打印出来微信返回的信息：

 1.推送消息请求微信接口=={"errcode":0,"errmsg":"ok","invaliduser":""}

2.推送消息请求微信接口=="{\"errcode\":0,\"errmsg\":\"ok\",\"invaliduser\":\"\"}"

WxConstants是自己定义的常量类，里面是微信的url
