Are there any plans to support http/2.0

[thousmile]

http server enable http2.0 .
But feign client still uses http/1.1 protocol

hello @OlgaMaciaszek , can you assign this issue to me.

[OlgaMaciaszek]

Sure @galaxy-sea :) .

[OlgaMaciaszek]

HTTP2 is supported by OkHttp and it's enabled by default. There's also support in Apache HC5. We should add the support for this within this issue.

[galaxy-sea]

hello @OlgaMaciaszek , feign.hc5.ApacheHttp5Client does not support the http2, but feign.hc5.AsyncApacheHttp5Client supports http2

[galaxy-sea]

I've sorted out the clients that support the http2 protocol. AsyncClients is the best for supporting the http2 protocol.

client	http/2.0
feign.Client.Default	no
feign.hc5.ApacheHttp5Client	no
feign.okhttp.OkHttpClient	yes
feign.http2client.Http2Client	yes

AsyncClient	http/2.0
feign.AsyncClient.Default	yes
feign.hc5.AsyncApacheHttp5Client	yes
ffeign.okhttp.OkHttpClient	yes
feign.http2client.Http2Client	yes

[galaxy-sea]

Maybe we need to implement the http2 protocol on the basis of Async feign flow #511.

Has this issue not been resolved yet? No matter which configuration is used, HTTP/2 will not be utilized. My server-side configuration should be fine because testing with curl works without any issues, but it doesn't work with OpenFeign.

@thousmile
大佬，你是怎么解决的啊。我这一直有问题，我是这么配置的。用 curl 测试了，我的服务端没问题，能用 HTTP/2，就是用 openfeign 不行。这个问题已经困扰我好多天了，我也引用了 okhttp 的依赖。但就是不行，一开始我用 httpclient5 的方式也不行。

发现你是中国人，我就不翻译成英文了，意思会被曲解。

spring:
  cloud:
    openfeign:
      client:
        refresh-enabled: true
      okhttp:
        enabled: true
      httpclient:
        ok-http:
          protocols:
            - H2_PRIOR_KNOWLEDGE

@galaxy-sea 非常感谢，原来我是被日志骗了
