PHP语句转C#语句
base64_encode将字符串以 BASE64 编码，本函数将字符串以 MIME BASE64 编码。此编码方式可以让中文字或者图片也能在网络上顺利传输。在 BASE64 编码后的字符串只包含英文字母大小写、阿拉伯数字、加号与反斜线，共 64 个基本字符，不包含其它特殊的字符，因而才取名 BASE64。编码后的字符串比原来的字符串长度再加 1/3 左右。更多的 BASE64 编码信息可以参考 RFC2045 文件之 6.8 节
algo
Name of selected hashing algorithm (i.e. "md5", "sha256", "haval160,4", etc..) Seehash_algos() for a list of supported algorithms.-phpbase64hmacsha1
data
Message to be hashed.
key
Shared secret key used for generating the HMAC variant of the message digest.
raw_output
When set to TRUE, outputs raw binary data. FALSE outputs lowercase hexits.

如果你的API服务安全认证协议中要求使用hmac_sha1方法对信息进行编码,
而你的服务是由PHP实现的,客户端是由JAVA实现的,那么为了对签名正确比对,就需要在两者之间建立能匹配的编码方式.
efine('ID','123456');
define('KEY','k123456');
$strToSign = "test_string";
$utf8Str = mb_convert_encoding($strToSign, "UTF-8");
$hmac_sha1_str = base64_encode(hash_hmac("sha1", $utf8Str, KEY));
$signature = urlencode($hmac_sha1_str);
print_r($signature);
JAVA侧需要注意如下几点:
1. hmac_sha1编码结果需要转换成hex格式
2. java中base64的实现和php不一致,其中java并不会在字符串末尾填补=号以把字节数补充为8的整数
3. hmac_sha1并非sha1, hmac_sha1是需要共享密钥的
参考实现如下:
[java] view plain copy
import java.io.UnsupportedEncodingException;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import org.apache.wicket.util.crypt.Base64UrlSafe;
public class test {
public static void main(String[] args) {
String key = "f85b8b30f73eb2bf5d8063a9224b5e90";
String toHash = "GET"+"\n"+"Thu, 09 Aug 2012 13:33:46 +0000"+"\n"+"/ApiChannel/Report.m";
//String toHashUtf8 = URLEncoder.encode(toHash, "UTF-8");
String res = hmac_sha1(toHash, key);
//System.out.print(res+"\n");
String signature;
try {
signature = new String(Base64UrlSafe.encodeBase64(res.getBytes()),"UTF-8");
signature = appendEqualSign(signature);
System.out.print(signature);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
public static String hmac_sha1(String value, String key) {
try {
// Get an hmac_sha1 key from the raw key bytes
byte[] keyBytes = key.getBytes();
SecretKeySpec signingKey = new SecretKeySpec(keyBytes, "HmacSHA1");
// Get an hmac_sha1 Mac instance and initialize with the signing key
Mac mac = Mac.getInstance("HmacSHA1");
mac.init(signingKey);
// Compute the hmac on input data bytes
byte[] rawHmac = mac.doFinal(value.getBytes());
// Convert raw bytes to Hex
String hexBytes = byte2hex(rawHmac);
return hexBytes;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
private static String byte2hex(final byte[] b){
String hs="";
String stmp="";
for (int n=0; nb.length; n++){
stmp=(java.lang.Integer.toHexString(b[n] 0xFF));
if (stmp.length()==1) hs=hs+"0"+stmp;
else hs=hs+stmp;
}
return hs;
}
private static String appendEqualSign(String s){
int len = s.length();
int appendNum = 8 - (int)(len/8);
for (int n=0; nappendNum; n++){
s += "%3D";
}
return s;
}
}
