又是一个获取身份卡NFT的项目，所以应该不会太复杂，准备看一下。

首先观察data数据，寻找规律。

这里的数据一直发生变化，我去跟踪网络的请求发现有一个post请求。

POST：

该请求地址：https://readon-api.readon.me/v1/manta_pacific/check_invite_code

参数：{“code”: “MYZETA”}

响应结果：

{
    "code": 0,
    "data": {
        "err_code": 0,
        "err_message": "",
        "token_id": "1704713737234946232",
        "signature": "0x4aaa6ff6fe3f8dc4eb417dae83ea1c5891d05530def4a28f08043099fd9fc8ae5cd528dd90e127cb7b945330131db3c638559d1fd25fa070e9dfcb5edcba448e1b"
    },
    "message": "success"
}

将这两个参数带入上面的data中，发现还缺少最后一个变量。

token_id数据转化为16进制，signature直接替换掉对应位置即可。

让GPT写代码，帮我们发送请求，并且获得到对应的数据。

package zeta.tools;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class HTTPPostRequestExample {

	public static void main(String[] args) {
		try {
			// 请求地址
			String url = "https://readon-api.readon.me/v1/manta_pacific/check_invite_code";

			// 创建URL对象
			URL obj = new URL(url);

			// 打开连接
			HttpURLConnection con = (HttpURLConnection) obj.openConnection();

			// 设置请求方法为POST
			con.setRequestMethod("POST");

			// 设置请求头部信息
			con.setRequestProperty("Content-Type", "application/json");

			// 设置需要发送的数据
			String postData = "{\"code\": \"MYZETA\"}";

			// 启用输出流
			con.setDoOutput(true);

			// 发送POST请求
			OutputStream os = con.getOutputStream();
			os.write(postData.getBytes());
			os.flush();
			os.close();

			// 获取响应代码
			int responseCode = con.getResponseCode();

			// 读取响应内容
			BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
			String inputLine;
			StringBuffer response = new StringBuffer();

			while ((inputLine = in.readLine()) != null) {
				response.append(inputLine);
			}
			in.close();

			// 判断请求是否成功
			if (responseCode == HttpURLConnection.HTTP_OK) {
				System.out.println("请求成功！");
				// 从响应中提取 token_id 和 signature 的值
				String jsonResponse = response.toString();
				// 解析 JSON 获取 token_id 和 signature
				// 这里可以使用 JSON 解析库如 JSON.simple 或者 Gson
				// 以下是用 JSON.simple 解析的示例代码

				 JSONParser parser = new JSONParser();
				 JSONObject jsonObject = (JSONObject) parser.parse(jsonResponse);
				 JSONObject dataObject = (JSONObject) jsonObject.get("data");
				 String tokenId = (String) dataObject.get("token_id");
				 String signature = (String) dataObject.get("signature");
//				 打印到控制台
				 System.out.println("Token ID: " + tokenId);
				 System.out.println("Signature: " + signature);
			} else {
				System.out.println("请求失败！");
			}
		} catch (Exception e) {
			System.out.println("发生异常：" + e.getMessage());
		}
	}
}

拼接data：

把上面的代码抽象成为一个方法。

然后我们开始拼接需要的data数据字符串。

其中有一个随机的字符串，他只需要随机即可（不能复制使用重复的内容）。

我们写一个随机的代码：

// 获取一个随机10位的16进制字符串
	public static String string0x16(){
		// 生成一个随机数生成器
		SecureRandom random = new SecureRandom();

		// 生成一个 StringBuilder 来存储随机字符串
		StringBuilder stringBuilder = new StringBuilder(10);

		// 循环生成随机字符，直到达到10位长度
		while (stringBuilder.length() < 10) {
			// 生成一个随机的16进制字符
			int randomValue = random.nextInt(16); // 生成0-15之间的随机数
			char hexChar = (randomValue < 10) ? (char) ('0' + randomValue) : (char) ('a' + randomValue - 10);

			// 将生成的随机字符追加到字符串中
			stringBuilder.append(hexChar);
		}
		return stringBuilder.toString();

	}

剩下的拼接就简单了。

我们把对应的数据填写好即可，我是直接写死在代码里面。

// 拼接字符串
		String data1 = "0xe816fc8f00000000000000000000000000000000000000000000000017a85";
		String data3 = "0000000000000000000000000000000000000000000000000000000000000008000000000000000000000000000000000000000000000000000000000000000c0000000000000000000000000000000000000000000000000000000000000010000000000000000000000000000000000000000000000000000000000000000064d595a45544100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000019";
		String data4 = ChineseToHex.chineseToHex(tokenId);
		String data5 = "4d595a455441000000000000000000000000000000000000000000000000000000000000000000000000000041";
		String data6 = signature.substring(2);
		String data7 = "00000000000000000000000000000000000000000000000000000000000000";
		// 生成随机字符串2
		String data2 = HTTPPostRequestExample.string0x16();
		return data1+data2+data3+data4+data5+data6+data7;

然后老样子，写一个EIP1559发送请求，将合约地址换成。

0xB028873223d6f9624368b4Bb488e0aBe6a2F3726

然后测试代码是否正常运行，如果可以，写上循环（批量获取钱包，批量执行）。

测试成功。

结果：

又批量完成一个任务。
