Conceptual HTTPS/HTTP question for golang repository
问题
我有一个使用Golang构建的Gateway API。我们使用了“net/http”库，文档在这里https://pkg.go.dev/net/http#example-ListenAndServeTLS。该服务已经设置了HTTPS连接。我使用TLS终止，所以与我的ELB的连接使用HTTPS。因此，这个Gateway API有SSL证书。但是，它将连接传递给其他实例时，使用的是普通的HTTP连接。
简而言之，Gateway API支持HTTPS，但连接到Gateway API的服务使用的是HTTP。
当我检查我的UI服务时，显示我们仍在使用HTTP 1.1。然而，根据Golang的文档，包“net/http”应该自动提供HTTP 2.0支持。
我是否需要升级我的内部服务，以使用HTTPS而不是HTTP，以便使用HTTP 2.0？
如果这篇文章显得无知或粗鲁，我很抱歉。我非常感谢任何花时间阅读这篇文章的人，并愿意提供任何需要的更多信息。

I have a Gateway API that is built with Golang. We use the "net/http" library documented here https://pkg.go.dev/net/http#example-ListenAndServeTLS. This service has HTTPS connection set up. The connections to my ELB’s use HTTPS because I use TLS termination. So this one Gateway API has the ssl cert. But then passes the connection to a regular HTTP connection to the other instances.
In short, the Gateway API has HTTPs support, but the services connected to my Gateway API uses HTTP.
When I check my UI services, It shows that we are using HTTP 1.1 still. However from Golang's documentation the package "net/http" should provide HTTP 2.0 support automatically.
Do I need to upgrade my internal services to use HTTPs instead of HTTP in order to use http 2.0?
Sorry If this post comes off as ignorant or rude. I really appreciate anyone taking there time to read this, and am willing to provide any more information that Is needed.

http2包括h2（使用TLS）和h2c（不使用TLS），net/http在使用ListenAndServeTLS时默认使用h2。
如果你使用http，net/http不会使用h2c，而是使用http1.1。目前没有浏览器支持未加密的HTTP/2。
因为net/http默认不支持h2c，如果你想使用h2c（非TLS版本的HTTP/2）：
https://pkg.go.dev/golang.org/x/net@v0.0.0-20220421235706-1d1ef9303861/http2/h2c
英文:
http2 include h2(TLS) h2c(no TLS), net/http use h2 default when ListenAndServeTLS.
if you use http, net/http not use h2c, but http1.1 currently no browser supports HTTP/2 unencrypted
becase net/http don't support h2c default, if you want use h2c(non-TLS version of HTTP/2):
https://pkg.go.dev/golang.org/x/net@v0.0.0-20220421235706-1d1ef9303861/http2/h2c
