Spring Cloud中Feign如何统一设置验证token

tatic class DynamicAuthTokenTarget<T> implements Target<T> {
public DynamicAuthTokenTarget(Class<T> clazz,
UrlAndTokenProvider provider,
ThreadLocal<String> requestIdProvider);
...
@Override
public Request apply(RequestTemplate input) {
TokenIdAndPublicURL urlAndToken = provider.get();
if (input.url().indexOf("http") != 0) {
input.insert(0, urlAndToken.publicURL);
}
input.header("X-Auth-Token", urlAndToken.tokenId);
input.header("X-Request-ID", requestIdProvider.get());

return input.request();
}
}
...
Bank bank = Feign.builder()
.target(new DynamicAuthTokenTarget(Bank.class, provider, requestIdProvider));
