能解决问题的码农是个好码农，能高效处理问题的AI是个好AI

需求：

提取返回结果中字段alarmlevelname 不等于1的结果。

    public static String ReadTagValue(String tagid, Date starttime,Date endtime)
    {
    
    

    	try {
    
    
    		
    	String appkey = "11"; 
    	String appsecret = "11";
		java.sql.Statement statement;
		SimpleDateFormat _dateformat = new SimpleDateFormat("yyyy-MM-dd");
		String _mindate = _dateformat.format(starttime);
		String _maxdate = _dateformat.format(endtime);
		String _strurl = "http://ip:1111/api/test/" + tagid + "?MinDate="+_mindate+"&MaxDate="+_maxdate;
		URL url = new URL(_strurl);
		HttpURLConnection conn = (HttpURLConnection)url.openConnection();
		conn.setRequestMethod("GET");
		conn.setConnectTimeout(15000);
		conn.setReadTimeout(60000);
		String stringNow = _dateformat.format(new Date());
		String uuid = UUID.randomUUID().toString();
		String _raw = appkey+stringNow+uuid;
		String _sig = RongzhiToDM.HMACSHA256(_raw, appsecret);
		
		conn.setRequestProperty("Time", stringNow );
		conn.setRequestProperty("Appkey", appkey);
		conn.setRequestProperty("RequestId", uuid);
		conn.setRequestProperty("Sign", _sig);
		conn.connect();
		
		int responseCode = conn.getResponseCode();
		if(responseCode == 200)
		{
    
    
			InputStream is = conn.getInputStream();
			BufferedReader br = new BufferedReader(new InputStreamReader(is,"UTF-8"));
			StringBuffer sbf = new StringBuffer();
			String temp = null;
			while((temp = br.readLine()) != null)
			{
    
    
				sbf.append(temp);
				sbf.append("\r\n");
			}
			String result = sbf.toString();
			return result;
		}
		else
		{
    
    
			String result = "{ ERROR:"+ responseCode+", MSG:";
			InputStream is = conn.getInputStream();
			BufferedReader br = new BufferedReader(new InputStreamReader(is,"UTF-8"));
			StringBuffer sbf = new StringBuffer();
			String temp = null;
			while((temp = br.readLine()) != null)
			{
    
    
				sbf.append(temp);
				sbf.append("\r\n");
			}
			result += sbf.toString();
			result +="}";
			return result;
		}
    	}
    	catch(Exception ex)
    	{
    
    
    		return "ERROR(API):"+ex.getMessage();
    	}
    }    

使用Cursor解决问题。

第一步

创建main.java文件

第二步

粘贴上面的代码

第三步

Ctrl+k 输入 提取alarmlevelname 不等于1的数据

AI帮助优化代码并完成了代码编写

private static String readInputStream(BufferedReader br) throws IOException {
    
    
    StringBuilder sb = new StringBuilder();
    String temp = null;
    while ((temp = br.readLine()) != null) {
    
    
        sb.append(temp);
        sb.append("\r\n");
    }
    return sb.toString();
}

public static String ReadTagValue(String tagid, Date starttime, Date endtime) {
    
    
    try {
    
    
        String appkey = "11";
        String appsecret = "11";
        SimpleDateFormat _dateformat = new SimpleDateFormat("yyyy-MM-dd");
        String _mindate = _dateformat.format(starttime);
        String _maxdate = _dateformat.format(endtime);
        String _strurl = "http://ip:1111/api/test"+"?MinDate=" + _mindate + "&MaxDate=" + _maxdate;
        URL url = new URL(_strurl);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setConnectTimeout(15000);
        conn.setReadTimeout(60000);

        String stringNow = _dateformat.format(new Date());
        String uuid = UUID.randomUUID().toString();
        String _raw = appkey + stringNow + uuid;
        String _sig = RongzhiToDM.HMACSHA256(_raw, appsecret);

        conn.setRequestProperty("Time", stringNow);
        conn.setRequestProperty("Appkey", appkey);
        conn.setRequestProperty("RequestId", uuid);
        conn.setRequestProperty("Sign", _sig);
        conn.connect();

        int responseCode = conn.getResponseCode();
        if (responseCode == 200) {
    
    
            try (InputStream is = conn.getInputStream();
                 BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"))) {
    
    
                String result = readInputStream(br);
                JSONArray jsonArray = new JSONArray(result);
                JSONArray filteredArray = new JSONArray();
                for (int i = 0; i < jsonArray.length(); i++) {
    
    
                    JSONObject jsonObject = jsonArray.getJSONObject(i);
                    if (!jsonObject.getString("alarmlevelname").equals("1")) {
    
    
                        filteredArray.put(jsonObject);
                    }
                }
                return filteredArray.toString();
            }
        } else {
    
    
            try (InputStream is = conn.getInputStream();
                 BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"))) {
    
    
                String result = "{ ERROR:" + responseCode + ", MSG:";
                result += readInputStream(br);
                result += "}";
                return result;
            }
        }
    }catch(Exception ex) {
    
    
    		return "ERROR(API):"+ex.getMessage();
    }
}

亦喜亦忧，多个学科领域挑战与机遇并存。

再次大力推荐Cursor的高效使用。
