Java Spring + Slack Web Hook API

Java Spring + Slack Web Hook API

슬랙으로 메시지를 보내기

1. 슬랙에서 채널을 생성

2. 원하는 채널을 선택하고, 접근API를 생성

- 메뉴 : https://my.slack.com/services/new/incoming-webhook/

- 설명 : api.slack.com -> incoming webhooks

3. 연동(Java) 모듈 생성

String hooksSlack = "https://hooks.slack.com/services/xx/yy/zz"; CloseableHttpClient client = HttpClients.createDefault(); HttpPost httpPost = new HttpPost(hooksSlack); String message = " " ; String json = "{ \"text\": \""+ message.toString() + "\" }"; StringEntity entity = new StringEntity(json); httpPost.setEntity(entity); httpPost.setHeader("Accept", "application/json"); httpPost.setHeader("Content-type", "application/json"); CloseableHttpResponse response = client.execute(httpPost); log.error("getStatusCode : " + response.getStatusLine().getStatusCode() ); //assertThat( response.getStatusLine().getStatusCode(), equalTo(200) ); client.close();
