java - 如何在 RESTEasy 3.0 客户端框架(使用 ResteasyClientBuilder 和 ResteasyWebTarget)中设置 HTTP header ？

Question

我正在尝试弄清楚如何设置类似于此处解释的 HTTP header :

• How to set HTTP header in RESTEasy client framework? , 或者在这里
• RESTEasy client framework authentication credentials

但是，我想使用 RESTeasy 3.0 功能(ResteasyClientBuilder 和 ResteasyWebtarget)而不是已弃用的 ProxyFactory，如下所述:

• What is the substitute for Resteasy ProxyFactory class

只是为了澄清，我也不想在每个请求上设置 header /不想将它们传递给客户端，我希望将它们设置在 ResteasyClientBuilder/ResteasyWebtarget 级别，如果可能。

Answer 1

找到解决方案。

诀窍是向 ResteasyClient 注册一个 ClientRequestFilter(下面方法的第 2 行):

public Resource getResource(Credentials credentials) {
    ResteasyClient client = new ResteasyClientBuilder().build();
    client.register(new AuthHeadersRequestFilter(credentials));
    return client.target(restServiceRoot).proxy(Resource.class);
}

然后让您的请求过滤器执行以下操作:

public class AuthHeadersRequestFilter implements ClientRequestFilter {

    private final String authToken;

    public AuthHeadersRequestFilter(Credentials credentials) {
        authToken = credentials.getAuthorizationHeader();
    }

    @Override
    public void filter(ClientRequestContext requestContext) throws IOException {
        requestContext.getHeaders().add("Authorization", authToken);
    }
}
