接口 SigningKeyResolver

所有已知实现类:

SigningKeyResolverAdapter

public interface SigningKeyResolver

A SigningKeyResolver can be used by a JwtParser to find a signing key that should be used to verify a JWS signature.

A SigningKeyResolver is necessary when the signing key is not already known before parsing the JWT and the JWT header or payload (plaintext body or Claims) must be inspected first to determine how to look up the signing key. Once returned by the resolver, the JwtParser will then verify the JWS signature with the returned key. For example:

 Jws<Claims> jws = Jwts.parser().setSigningKeyResolver(new SigningKeyResolverAdapter() {
         @Override
         public byte[] resolveSigningKeyBytes(JwsHeader header, Claims claims) {
             //inspect the header or claims, lookup and return the signing key
             return getSigningKeyBytes(header, claims); //implement me
         }})
     .parseClaimsJws(compact);
 

A SigningKeyResolver is invoked once during parsing before the signature is verified.

SigningKeyResolverAdapter

If you only need to resolve a signing key for a particular JWS (either a plaintext or Claims JWS), consider using the SigningKeyResolverAdapter and overriding only the method you need to support instead of implementing this interface directly.

resolveSigningKey

java.security.Key resolveSigningKey(JwsHeader header,
                                  Claims claims)

Returns the signing key that should be used to validate a digital signature for the Claims JWS with the specified header and claims.

参数:

header - the header of the JWS to validate

claims - the claims (body) of the JWS to validate

返回:

the signing key that should be used to validate a digital signature for the Claims JWS with the specified header and claims.

resolveSigningKey

java.security.Key resolveSigningKey(JwsHeader header,
                                  java.lang.String plaintext)

Returns the signing key that should be used to validate a digital signature for the Plaintext JWS with the specified header and plaintext payload.

参数:

header - the header of the JWS to validate

plaintext - the plaintext body of the JWS to validate

返回:

the signing key that should be used to validate a digital signature for the Plaintext JWS with the specified header and plaintext payload.
