问题描述
我正在尝试使用C#使用REST API。
I am trying to make use of a REST API using C#.
API创建者在下面提供了用于创建hmac的伪代码。
The API creator has provided below pseudo code for hmac creation.
var key1 = sha1(body);
var key2 = key1 . SECRET_KEY;
var key3 = sha1(key2);
var signature = base64_encode(key3);
在上面的伪代码中,body是html request body string,而SECRET_KEY
是
In the above pseudo code , body is html request body string , and SECRET_KEYis the secret key provided by REST API provider.
据我所知,我需要使用System.Security.Cryptography.HMACSHA1类
来实现这一点。
As per my knowledge , I need to use System.Security.Cryptography.HMACSHA1 classto implement this.
但是无法完全在C#中实现上述逻辑。
But am not able to completely implement above logic in C#.
有什么建议吗?
推荐答案
将上面的代码直接映射到C#就像是这样:
Direct mapping of above code to C# would be something like:
static string ComputeSignature(byte[] body, byte[] secret) {
using (var sha1 = SHA1.Create())
{
var key1 = sha1.ComputeHash(body);
var key2 = key1.Concat(secret).ToArray();
var key3 = sha1.ComputeHash(key2);
return Convert.ToBase64String(key3);
}
}
如果将请求正文作为字符串,请将其转换使用正确的编码转换为字节数组,例如:
If you have request body as a string, convert it to byte array using proper encoding, for example:
var body = Encoding.UTF8.GetBytes(bodyAsString);
如果您的秘密作为字符串-这取决于api开发人员期望它如何转换为字节数组。很可能已经是十六进制或base64编码的字符串。
If you have your secret as string - that depends on how api developer expects it to be converted to byte array. Most likely it's already HEX or base64-encoded string.
