如何使用Spring的WebClient发送带有自定义标头的删除请求?

我要发送带有自定义标头的http删除请求。

我尝试使用Spring的WebClient通过以下代码进行此操作:

@Test
public void validateDeleteCouldCarryHeader() {
    WebClient.create("https://jira.spring.io/")
            .delete()
            .header("X-FOO", "BAR")
            .retrieve()
            .bodyToMono(Map.class)
            .block();
}

我期望的是类似的东西

DELETE / HTTP/1.1
X-FOO: BAR 
...
content-length: 0

但是,实际发出的请求是:

DELETE / HTTP/1.1
user-agent: ReactorNetty/0.7.0.RELEASE
host: jira.spring.io
accept: */*
accept-encoding: gzip
content-length: 0

我错过了一些包含自定义标头 X-FOO 的东西吗?

更新1:我将反应堆的网络等级升级到0.7.3.RELEASE,

丢失的标题仍然丢失:

DELETE / HTTP/1.1
user-agent: ReactorNetty/0.7.3.RELEASE
host: jira.spring.io
accept: */*
accept-encoding: gzip
content-length: 0

更新2:我发现在pom中导入了一个反应堆的BOM(铋释放),在删除该BOM后,Spring Boot 2.0.5.RELEASE包含了我想要的自定义标头。

DELETE / HTTP/1.1
user-agent: ReactorNetty/0.7.9.RELEASE
host: jira.spring.io
accept: */*
accept-encoding: gzip
X-FOO: BAR

答案 0 :(得分:0)

Reactor Netty 0.7.0.RELEASE现在已经很旧了,应该升级到新版本。

我已经尝试过复制,但是不能。

reactor.ipc.netty.http.client.HttpClient的日志级别设置为“调试”将显示以下内容:

因此,客户端确实在发送这些标头。您捕获外发请求信息的方式可能有问题吗?
