Java WebClient-添加DefaultHeader

我试图将多个头放入defaultHeaders（）中，但我不知道如何从createHeaders（）方法的返回创建使用者对象

---

但如何将其包装到消费者中？

您可以这样做：

WebClient client3 = WebClient
      .builder()
        .baseUrl(someConfiguration.getApiUrl())
        .clientConnector(buildTimeoutConnector())
        .defaultHeader(HttpHeaders.ACCEPT, V1_PUBLIC) 
        .defaultHeader(HttpHeaders.HOST, "abc") 
        .defaultHeader(HttpHeaders.AUTHORIZATION, "Bearer " + token) 
      .build();

很明显，方法文档说它需要某种类型的

消费者。因此，您可以创建一个实现
消费者
接口的匿名类，或者像这样使用lambda表达式：

使用匿名内部类：
private HttpHeaders createHeaders(String token) {
    HttpHeaders headers = new HttpHeaders();
    headers.add(HttpHeaders.ACCEPT, V1_PUBLIC);
    headers.add(HttpHeaders.HOST, "abc");
    headers.add(HttpHeaders.AUTHORIZATION, "Bearer " + token);
    return headers;
}

WebClient client3 = WebClient
      .builder()
        .baseUrl(someConfiguration.getApiUrl())
        .clientConnector(buildTimeoutConnector())
        .defaultHeader(HttpHeaders.ACCEPT, V1_PUBLIC) 
        .defaultHeader(HttpHeaders.HOST, "abc") 
        .defaultHeader(HttpHeaders.AUTHORIZATION, "Bearer " + token) 
      .build();

this.someWebClient = WebClient.builder()
        .baseUrl(someConfiguration.getApiUrl())
        .clientConnector(buildTimeoutConnector())
        .defaultHeaders(new Consumer<HttpHeaders>() {
          @Override
          public void accept(HttpHeaders httpHeaders) {
            httpHeaders.addAll(createHeaders(token));
          }
        })
        .build();

this.someWebClient = WebClient.builder()
        .baseUrl(someConfiguration.getApiUrl())
        .clientConnector(buildTimeoutConnector())
        .defaultHeaders(httpHeaders -> {
          httpHeaders.addAll(createHeaders(token));
        })
        .build();
