如何在RESTEasy 3.0客户端框架中设置HTTP标头（使用ResteasyClientBuilder和ResteasyWebTarget）？ [英] How to set HTTP header in RESTEasy 3.0 client framework (with ResteasyClientBuilder and ResteasyWebTarget)?

问题描述

我正在试图弄清楚如何设置类似于此处解释的HTTP标头：

I'm trying to figure out how to set HTTP headers similar to what was explained here:

• 如何在RESTEasy客户端框架中设置HTTP标头？，或者


• RESTEasy客户端框架身份验证凭据

• How to set HTTP header in RESTEasy client framework?, or here
• RESTEasy client framework authentication credentials

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

However, I want to use RESTeasy 3.0 functionality (ResteasyClientBuilder and ResteasyWebtarget) and not the deprecated ProxyFactory, as explained here:

• 什么是Resteasy ProxyFactory类的替代品

• What is the substitute for Resteasy ProxyFactory class

为了澄清，我也不想设置标题在每个请求上/不希望它们被传递给clie如果可能的话，我希望它们能在ResteasyClientBuilder / ResteasyWebtarget级别设置。

And just to clarify, I also do not want to set the header(s) on every request / don't want them to be passed to the client, I'd like them to be set on ResteasyClientBuilder/ResteasyWebtarget level if possible.

推荐答案

找到解决方案。

诀窍是使用ResteasyClient注册ClientRequestFilter（下面方法的第2行）：

The trick is to register a ClientRequestFilter with the ResteasyClient (line #2 of the method below):

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：

And then have your request filter do something like:

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);
    }
}
