如何在单个SSL连接上发送多个HTTP2.0请求？
我尝试了以下操作，HTTP1.1正常运行，但是HTTP2.0失败。
$ openssl s_client -alpn h2 -connect navaztheking.com:443
CONNECTED(00000003)
depth=4 C = US, O = "Starfield Technologies, Inc.", OU = Starfield Class 2 Certification Authority
verify return:1
depth=3 C = US, ST = Arizona, L = Scottsdale, O = "Starfield Technologies, Inc.", CN = Starfield Services Root Certificate Authority - G2
verify return:1
depth=2 C = US, O = Amazon, CN = Amazon Root CA 1
verify return:1
depth=1 C = US, O = Amazon, OU = Server CA 1B, CN = Amazon
verify return:1
depth=0 CN = navaztheking.com
verify return:1

GET / HTTP/1.1
Host: navaztheking.coclosed

您在上方看到的只是“关闭”连接。数据包捕获显示客户端未发送请求。我该如何实现。
我尝试了“ curl --http2”，该方法可以正常工作，但是我无法在curl上发送多个请求。
在此示例中，您没有发送HTTP/2请求。您正在使用HTTP / 2的应用程序协议标识符创建TLS连接，但是随后以HTTP / 1.1格式发送纯文本数据。这将不会被HTTP / 2端点接受，并且连接只会被关闭。
为了发送一个（或多个）HTTP / 2请求，您将需要使用一个以正确的HTTP / 2格式发送请求的库。
curl是一个库和CLI工具，可以发送正确的HTTP / 2请求。为了使用CLI版本发送多个请求，您可能可以使用--next选项。
