钉钉机器人

python版对接

钉钉机器人后台中创建机器人并保存webhookURL，

python中直接POST调用URL

 后续脚本中直接调用send_ding方法即可（字符串传参）

java调用方式：

用java发送post请求给钉钉完成消息推送

package com.thinkgem.wlw.modules.lhjh.DingTalk;

import com.alibaba.fastjson.JSON;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.*;
import java.net.URL;
import java.net.URLConnection;
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;
/**

public class SendHttps {
private static Logger logger = LoggerFactory.getLogger(SendHttps.class);
/**
* 发送POST请求，参数是Map, contentType=x-www-form-urlencoded
*
* @param url
* @param mapParam
* @return
*/
public static String sendPostByMap(String url, Map<String, Object> mapParam) {
Map<String, String> headParam = new HashMap();
headParam.put("Content-type", "application/json;charset=UTF-8");
return sendPost(url, mapParam, headParam);
}

/**
* 向指定 URL 发送POST方法的请求
*
* @param url 发送请求的 URL
* @param param 请求参数，
* @return 所代表远程资源的响应结果
*/
public static String sendPost(String url, Map<String, Object> param, Map<String, String> headParam) {
PrintWriter out = null;
BufferedReader in = null;
String result = "";
try {
URL realUrl = new URL(url);
// 打开和URL之间的连接
URLConnection conn = realUrl.openConnection();
// 设置通用的请求属性 请求头
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent",
"Fiddler");

if (headParam != null) {
for (Entry<String, String> entry : headParam.entrySet()) {
conn.setRequestProperty(entry.getKey(), entry.getValue());
}
}
// 发送POST请求必须设置如下两行
conn.setDoOutput(true);
conn.setDoInput(true);
// 获取URLConnection对象对应的输出流
out = new PrintWriter(conn.getOutputStream());
// 发送请求参数
out.print(JSON.toJSONString(param));
// flush输出流的缓冲
out.flush();
// 定义BufferedReader输入流来读取URL的响应
in = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
result += line;
}
} catch (Exception e) {
logger.info("发送 POST 请求出现异常！" + e);
e.printStackTrace();
}
//使用finally块来关闭输出流、输入流
finally {
try {
if (out != null) {
out.close();
}
if (in != null) {
in.close();
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
return result;
}
}

编写测试类：

package com.thinkgem.wlw.modules.lhjh.DingTalk;

import java.util.HashMap;
import java.util.Map;

/**
* @Author: zhouhe
* @Date: 2019/6/20 14:52
*/
public class SendMessage {
public static void main(String[] args){

// 钉钉的webhook
String dingDingToken="https://oapi.dingtalk.com/robot/send?access_token=0f0daca33m98gn78f00189fe1e1e908b81fa26d0d8ddd48fa78a844cd8636187";
// 请求的JSON数据，这里我用map在工具类里转成json格式
Map<String,Object> json=new HashMap();
Map<String,Object> text=new HashMap();
json.put("msgtype","text");
text.put("content","XXXXXXXXXXXXX");
json.put("text",text);
// 发送post请求
String response = SendHttps.sendPostByMap(dingDingToken, json);
System.out.println("相应结果："+response);

}
}
