How to use java to realize the message push function of nailing robot

Editor to share with you how to use java to achieve nailing robot message push function, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

First build a group of nails and add robots

At this point, the robot has been added, and then write the code to connect the robot brother.

Import com.alibaba.fastjson.JSON;import com.google.common.collect.Lists;import com.google.common.collect.Maps;import java.util.List;import java.util.Map / * @ author yanghao * @ version DingTalkTest.java, v 2019-03-29 11:36 * / public class DingTalkTest {public static void main (String [] args) {try {/ / address of the nailing robot (webhook with robot) String dingUrl = "https://oapi.dingtalk.com/robot/send?access_token=............"; / / whether to notify the owner boolean isAtAll = false / / notify the specific person's mobile phone number list List mobileList = Lists.newArrayList (); / / nailing robot message content String content = "Hello, little brother!" / / Assembly request content String reqStr = buildReqStr (content, isAtAll, mobileList); / / push message (http request) String result = HttpUtil.postJson (dingUrl, reqStr); System.out.println ("result = =" + result);} catch (Exception e) {e.printStackTrace () }} / * Assembly request message * @ param content * @ return * / private static String buildReqStr (String content, boolean isAtAll, List mobileList) {/ / message content Map contentMap = Maps.newHashMap (); contentMap.put ("content", content); / / notifier Map atMap = Maps.newHashMap (); / / 1. Whether to notify the owner of atMap.put ("isAtAll", isAtAll); / / 2. Notify the specific person's list of mobile phone numbers atMap.put ("atMobiles", mobileList); Map reqMap = Maps.newHashMap (); reqMap.put ("msgtype", "text"); reqMap.put ("text", contentMap); reqMap.put ("at", atMap); return JSON.toJSONString (reqMap);}}

The running results are as follows:

Result = {"errmsg": "ok", "errcode": 0}

The nail group displays the message:

Ok, simple message push, this is done!

Let's test again to notify everyone and notify specific people.

Change isAtAll to true

/ / whether to notify the owner boolean isAtAll = true;// notify the specific person's mobile phone number list List mobileList = Lists.newArrayList ()

Add the list of notifier numbers (Note: isAtAll and mobileList cannot be effective at the same time)

/ / whether to notify the owner boolean isAtAll = false;// to notify the specific person's list of mobile phone numbers List mobileList = Lists.newArrayList (); mobileList.add ("182 *")

Let's test the special symbols again.

Newline identifier

/ * * newline identifier * / private static final String NEWLINE = "\ n"; / / nailing robot message content / / String content = "Hello, little brother!" ; StringBuffer sb = new StringBuffer (); sb.append ("Hello, little brother!") .append (NEWLINE) .append ("read a book"); String content = sb.toString ()

Emoji Picture

First get the unicode coding of the emoji image

The code is as follows:

/ * * Apple unicode code * / private static final String APPLE = "\ ud83c\ udf4e"; / / nailing robot message content / / String content = "Hello, little brother!" ; StringBuffer sb = new StringBuffer (); sb.append ("Hello, little brother!") .append (NEWLINE) .append ("read a book") .append (NEWLINE) .append ("eat") .append (APPLE); String content = sb.toString ()

Usually in our project, as some alarm to join, convenient and practical very interesting nailing robot, a lot of practical skills, you can explore a wave in depth!

Many friends leave messages to consult the http request. Here are 2 http request codes.

1. Maven project

Add dependency

Cn.hutool hutool-all 4.0.12

Http request code

Private static final int timeout = 10000; public static String postJson (String url, String reqStr) {String body = null; try {body = HttpRequest.post (url) .body (reqStr) .timeout (timeout). Execute (). Body ();} catch (Exception e) {e.printStackTrace ();} return body;}

two。 Non-maven project

Add jar package httpclient-xxx.jarcommons-logging-xxx.jar

Http request code

Public static String postJson (String url, String body) {/ / create Httpclient object CloseableHttpClient httpClient = createCustomClient (); CloseableHttpResponse response = null; String resultString = null; try {/ / create HttpPost request HttpPost httpPost = new HttpPost (url); httpPost.addHeader ("Content-Type", "application/json"); if (body! = null) {httpPost.setEntity (new StringEntity (body, "utf-8")) } / / execute http request response = httpClient.execute (httpPost); resultString = EntityUtils.toString (response.getEntity (), "utf-8");} catch (Exception e) {e.printStackTrace ();} finally {try {if (response! = null) {response.close ();}} catch (Exception e) {e.printStackTrace ();}} return resultString } public static CloseableHttpClient createCustomClient () {RequestConfig defaultRequestConfig = RequestConfig.custom () .setSocketTimeout (120 * 1000) .setConne ctionRequestTimeout (120 * 1000) .setStaleConnectionCheckEnabled (true) .build (); return HttpClients.custom (). SetDefaultRequestConfig (defaultRequestConfig). Build (); above is all the contents of the article "how to use java to achieve the message push function of nailing robot". Thank you for reading!
