Question

我有一个有效的OAuth2RestTemplate客户端（我使用的是spring-security-oauth2 2.0.7.RELEASE）。现在我想将它暴露/包装为AsyncRestTemplate以利用ListenableFuture的异步语义。不幸的是，以下简单的方法不起作用：

// instantiate and configure OAuth2RestTemplate - works
OAuth2RestTemplate oAuth2RestTemplate = new OAuth2RestTemplate(...);

// wrap sync restTemplate with AsyncRestTemplate - doesn't work 
AsyncRestTemplate asyncRestTemplate = new AsyncRestTemplate(
    new HttpComponentsAsyncClientHttpRequestFactory(), oAuth2RestTemplate);

如何将我的HTTP服务的OAuth2 Rest客户端作为AsyncRestTemplate？

Answer 1

好的，我能够通过手动设置＆＃34;授权＆＃34;使AsyncRestTemplate工作。来自OAuth2RestTemplate的accessToken标头;这里是Spring的java配置：

@Bean
public OAuth2RestTemplate restTemplate() {
    ClientCredentialsResourceDetails details = new ClientCredentialsResourceDetails();
    // configure oauth details

    OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(details);
    restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());

    return restTemplate;
}

@Bean
public AsyncRestTemplate asyncRestTemplate(final OAuth2RestTemplate oAuth2RestTemplate) {
    HttpComponentsAsyncClientHttpRequestFactory asyncRequestFactory = new HttpComponentsAsyncClientHttpRequestFactory() {
        @Override
        public AsyncClientHttpRequest createAsyncRequest(URI uri, HttpMethod httpMethod) throws IOException {
            AsyncClientHttpRequest asyncRequest = super.createAsyncRequest(uri, httpMethod);

            OAuth2AccessToken accessToken = oAuth2RestTemplate.getAccessToken();
            asyncRequest.getHeaders().set("Authorization", String.format("%s %s", accessToken.getTokenType(), accessToken.getValue()));

            return asyncRequest;
        }
    };
    return new AsyncRestTemplate(asyncRequestFactory, oAuth2RestTemplate);
}

我希望有更简单的方法在Spring中将配置的OAuth2RestTemplate公开为AsyncRestTemplate。

上述工作，但我发现了一种更简洁的方法。注册实施private void getIntentData() { Bundle bundle = getIntent().getExtras(); if (bundle != null) Strin url = bundle.getString(key); }

示例代码：

AsyncClientHttpRequestInterceptor

然后将其注册到您的private class Oauth2RequestInterceptor implements AsyncClientHttpRequestInterceptor { private final OAuth2RestTemplate oAuth2RestTemplate; public Oauth2RequestInterceptor( OAuth2RestTemplate oAuth2RestTemplate ) { this.oAuth2RestTemplate = oAuth2RestTemplate; } public ListenableFuture<ClientHttpResponse> intercept( HttpRequest request, byte[] body, AsyncClientHttpRequestExecution execution ) throws IOException { OAuth2AccessToken accessToken = oAuth2RestTemplate.getAccessToken(); request.getHeaders() .set( "Authorization", String.format( "%s %s", accessToken.getTokenType(), accessToken.getValue() ) ); return execution.executeAsync( request, body ); } }：

AsyncRestTemplate
