如何将api中包含数据的字符串放入HashMap或字典中？

import java.util.HashMap;

public class Main {
    public static void main(String[] args) {
        String dataString = "key1=value1&key2=value2&key3=value3";
        
        // 创建一个HashMap对象
        HashMap<String, String> dataMap = new HashMap<>();
        
        // 解析数据字符串
        String[] keyValuePairs = dataString.split("&");
        for (String pair : keyValuePairs) {
            String[] keyValue = pair.split("=");
            if (keyValue.length == 2) {
                String key = keyValue[0];
                String value = keyValue[1];
                dataMap.put(key, value);
            }
        }
        
        // 输出HashMap中的数据
        for (String key : dataMap.keySet()) {
            String value = dataMap.get(key);
            System.out.println(key + ": " + value);
        }
    }
}

key1: value1
key2: value2
key3: value3
