OkHttp本身并不直接支持Digest认证,可以通过拦截器（Interceptor）来手动实现Digest认证的逻辑。

1、自定义Digest认证拦截器

@Slf4j
public class DigestAuthInterceptor implements Interceptor {
    @NotNull
    @Override
    @SneakyThrows
    public Response intercept(@NotNull Chain chain)  {
        Request original = chain.request();
        String ha1 = calculateHA1(USERNAME, REALM, PASSWORD);

        String method = original.method();
        String url = original.url().toString();
        String ha2 = calculateHA2(method, url);

        String nonce = generateNonce();
        String cNonce = generateNonce();
        String response = calculateResponse(ha1, nonce, NONCE_COUNT, cNonce, QOP, ha2);

        //构建Authorization头信息
        String authHeader = "Digest username=\"" + USERNAME + "\",realm=\"" + REALM + "\",nonce=\"" + nonce + "\",uri=\"" + url + "\",nc=" + NONCE_COUNT + ",cnonce=\"" + cNonce + "\",qop=" + QOP + ",response=\"" + response + "\"";
