使用HttpClient访问WebHook

代码:

import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class ChatbotSend {
    //WebHook地址xxx
    public static String WEBHOOK_TOKEN = "http://localhost:8081/api/v1/scaninfowebhook";
    
    public static void main(String args[]) throws Exception {
        HttpClient httpclient = HttpClients.createDefault();
        HttpPost httppost = new HttpPost(WEBHOOK_TOKEN);
        httppost.addHeader("Content-Type", "application/json; charset=utf-8");
        //构建一个json格式字符串textMsg，其内容是接收方需要的参数和消息内容 
        String textMsg = "{"text":"hello"}";
        StringEntity se = new StringEntity(textMsg, "utf-8");
        
        httppost.addHeader("BOX-SIGNATURE-VERSION", "1");
        httppost.addHeader("BOX-SIGNATURE-ALGORITHM", "HmacSHA256");
        
        
        httppost.addHeader("BOX-DELIVERY-ID", "1911001047");
        httppost.addHeader("BOX-DELIVERY-TIMESTAMP", "2019-12-09T02:27:42-07:00");
        
        httppost.addHeader("BOX-SIGNATURE-PRIMARY", "uwleyFtFbAs+W6GmQMlPwzwLUtTQc77XQSIJP2Qak5A=");
        httppost.addHeader("BOX-SIGNATURE-SECONDARY", "uwleyFtFbAs+W6GmQMlPwzwLUtTQc77XQSIJP2Qak5A=");
        
        
        httppost.setEntity(se);
        HttpResponse response = httpclient.execute(httppost);
        if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
            String result = EntityUtils.toString(response.getEntity(), "utf-8");
            System.out.println(result);
        }
    }
}
