集成钉钉机器人

OkHttpUtils.postString() .mediaType(MediaType.parse("application/json; charset=utf-8"))
.url(webhook).content("{\"text\":{\"content\":\"关键词: 我就是我,333是不一样444的烟火\"},\"msgtype\":\"text\"}")
.build().execute(new StringCallback() {
@Override
public void onError(Call call, Exception e, int i) {
e.printStackTrace();
}

@Override
public void onResponse(String s, int i) {
System.out.println("s = " + s);
}
});
