数据结构

export interface ApifoxModel {
    data: Data;
    msg: string;
    ret: number;
    [property: string]: any;
}

export interface Data {
    /**

     */
    chatrooms: string[];
    /**
     * 好友的wxid
     */
    friends: string[];
    /**
     * 关注的公众号ID
     */
    ghs: string[];
    [property: string]: any;
}

使用Java编写一个微信机器人程序,你需要先了解微信开放平台的接口文档和Java开发环境的相关知识。 以下是一个简单的微信机器人程序示例,它可以自动回复用户发送的文本消息: ```java import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.URL; import java.util.Date; import java.util.HashMap; import java.util.Map; import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONObject; public class WeChatRobot { private static final String API_URL = "https://api.weixin.qq.com/cgi-bin/"; private String accessToken; public WeChatRobot(String appId, String appSecret) { accessToken = getAccessToken(appId, appSecret); } private String getAccessToken(String appId, String appSecret) { String url = API_URL + "token?grant_type=client_credential&appid=" + appId + "&secret=" + appSecret; String result = sendGet(url); JSONObject json = JSON.parseObject(result); return json.getString("access_token"); } public void handleMessage(JSONObject message) { String fromUser = message.getString("FromUserName"); String toUser = message.getString("ToUserName"); String msgType = message.getString("MsgType"); String content = message.getString("Content"); if ("text".equals(msgType)) { String reply = "你发送的消息是:" + content; sendMessage(fromUser, toUser, reply); } } private void sendMessage(String fromUser, String toUser, String content) { String url = API_URL + "message/custom/send?access_token=" + accessToken; Map<String, Object> message = new HashMap<>(); message.put("touser", fromUser); message.put("msgtype", "text"); Map<String, String> text = new HashMap<>(); text.put("content", content); message.put("text", text); String json = JSON.toJSONString(message); sendPost(url, json); } private String sendGet(String url) { try { URL obj = new URL(url); HttpURLConnection con = (HttpURLConnection) obj.openConnection(); con.setRequestMethod("GET"); InputStream is = con.getInputStream(); BufferedReader in = new BufferedReader(new InputStreamReader(is)); String inputLine; StringBuffer response = new StringBuffer(); while ((inputLine = in.readLine()) != null) { response.append(inputLine); } in.close(); return response.toString(); } catch (Exception e) { e.printStackTrace(); return null; } } private String sendPost(String url, String json) { try { URL obj = new URL(url); HttpURLConnection con = (HttpURLConnection) obj.openConnection(); con.setRequestMethod("POST"); con.setRequestProperty("Content-Type", "application/json"); con.setDoOutput(true); con.getOutputStream().write(json.getBytes()); InputStream is = con.getInputStream(); BufferedReader in = new BufferedReader(new InputStreamReader(is)); String inputLine; StringBuffer response = new StringBuffer(); while ((inputLine = in.readLine()) != null) { response.append(inputLine); } in.close(); return response.toString(); } catch (Exception e) { e.printStackTrace(); return null; } } public static void main(String[] args) { String appId = "你的AppID"; String appSecret = "你的AppSecret"; WeChatRobot robot = new WeChatRobot(appId, appSecret); while (true) { String url = API_URL + "message/custom/send?access_token=" + robot.accessToken; String result = robot.sendGet(url); JSONObject json = JSON.parseObject(result); int errcode = json.getIntValue("errcode"); if (errcode == 0) { JSONObject message = json.getJSONObject("message"); robot.handleMessage(message); } else { System.out.println("获取消息失败,错误码:" + errcode); } try { Thread.sleep(5000); } catch (InterruptedException e) { e.printStackTrace(); } } } } ``` 在这个示例中,我们使用了阿里巴巴的 fastjson 库来处理 JSON 数据,使用 HttpURLConnection 类来发送 HTTP 请求。在主函数中,我们使用一个死循环来不断地获取用户发来的消息,并调用 handleMessage 方法来处理消息。当收到文本消息时,我们会回复用户发送的文本内容。 在实际的开发中,你需要根据微信开放平台的接口文档,选择合适的接口来实现你的微信机器人功能。同时,你需要注意保护用户的隐私信息,并遵循微信开放平台的规定和政策。
