以下是使用Java语言实现的示例代码:
```
import javax.crypto.Mac;
import.crypto.spec.SecretKeySpec;
import java.net.URLEncoderimport java.nio.charset.StandardCharsets;
import java.security.InvalidException;
import java.security.NoSuchAlgorithmException;
import java.util64;
public class HmacSHA1 {
private final String HMAC_SHA1_ALGORITHM = "HmacSHA1";
public static String calculateRFC2104HMAC(String data, String key)
throws NoSuchAlgorithmException, InvalidKeyException {
SecretKeySpec signingKey = new SecretKeySpec(key.getBytes(StandardCharsets.UTF_8), HMAC_SHA1_ALGORITHM);
Mac mac = Mac.getInstance(HMAC_SHA1_ALGORITHM);
mac.init(signingKey);
byte[] rawHmac = mac.doFinal(data.getBytes(StandardCharsets.UTF_8));
return Base64.getEncoder().encodeToString(rawHmac);
}
public static void main(String[] args) throws Exception {
String appid = "your_appid";
String access_token = "your_access_token";
String time_stamp = "your_time_stamp";
String data = "{}";
String key = "your_secret_key";
String encodedData = URLEncoder.encode(data, StandardCharsets.UTF_8.name());
String url = "http://your_api_url?appid=" + appid + "&access_token=" + access_token
+ "&time_stamp=" + time_stamp;
String stringToSign = "POST" + "\n" + url + "\n" + encodedData;
String signature = calculateRFC2104HMAC(stringToSign, key);
String httpCode = "POST " + url + " HTTP/1.1\r\n"
+ "Content-Type: application/json\r\n"
+ "Authorization: hmac-sha1 " + appid + ":" + access_token + ":" + signature + ":" + time_stamp + "\r\n"
+ "Content-Length: " + encodedData.length() + "\r\n\r\n"
+ encodedData;
System.out.println(httpCode);
}
}
```
在上面的示例代码中,我们使用了Java标准库提供的javax.crypto包中的类来实现HmacSHA1签名算法。首先定义了一个calculateRFC2104HMAC方法,该方法用于计算HmacSHA1签名值。然后在main方法中,我们给出了需要签名的数据,包括appid、access_token、time_stamp和返回值Body{}参数。接着我们将需要签名的数据进行URL编码,然后按照规定的格式拼接成待签名的字符串。最后,我们使用计算出来的签名值,拼接成Authorization头部的值,生成最终的HTTP请求代码。
需要注意的是,在实际使用中,需要将上面的示例代码中的"your_appid"、"your_access_token"、"your_time_stamp"和"your_secret_key"替换成实际的值。同时,需要将"http://your_api_url"替换成实际的API接口URL。
