### Java Example for Generating GET Request Parameter String

Source: https://ourbitdevelop.github.io/apidocs

This utility method formats a map of parameters into a URL-encoded string, sorted by key, suitable for GET or DELETE requests. It handles empty maps and ensures proper encoding.

```java
/**
 * 获取get请求参数字符串
 *
 * @param param get/delete请求参数map
 * @return
 */
public static String getRequestParamString(Map<String, String> param) {
    if (MapUtils.isEmpty(param)) {
        return "";
    }
    StringBuilder sb = new StringBuilder(1024);
    SortedMap<String, String> map = new TreeMap<>(param);
    for (Map.Entry<String, String> entry : map.entrySet()) {
        String key = entry.getKey();
        String value = StringUtils.isBlank(entry.getValue()) ? "" : entry.getValue();
        sb.append(key).append('=').append(urlEncode(value)).append('&');
    }
    sb.deleteCharAt(sb.length() - 1);
    return sb.toString();
}
```

    return sb.toString();
}

public static String urlEncode(String s) {

    } catch (UnsupportedEncodingException e) {
        throw new IllegalArgumentException("UTF-8 encoding not supported!");

### Signature Calculation Steps

Source: https://ourbitdevelop.github.io/apidocs

Steps to construct the string for signature generation.

```APIDOC
1. Obtain the request parameter string:
   - GET/DELETE: Sort business parameters alphabetically, join with '&', URL-encode special characters if necessary.
   - POST: Use the JSON string of the request body (no alphabetical sorting).
   - If no parameters, use an empty string.
2. Construct the signature target string: accessKey + timestamp + parameter string.
3. Sign the target string using HMAC SHA256 with your Secret Key.
4. The resulting signature string is placed in the 'Signature' header. Do not Base64 encode the signature.
```
