发送http2请求时，request close #6
Description
参照文档中给出的例子，我改造了了一下，如下，并进行访问，得到了 client:request() failed: closed 的错误。
local on_headers_reach = function(ctx, headers)
print("received HEADERS frame:")
for k, v in pairs(headers) do
print(k, ": ", v)
end
end
local on_data_reach = function(ctx, data)
print("received DATA frame:")
print(data)
end
local on_trailers_reach = function(ctx, data)
print("received HEADERS frame for trailer headers:")
for k, v in pairs(headers) do
print(k, ": ", v)
end
end
local host = "10.148.165.39"
local port = 8081
local sock = ngx.socket.tcp()
print('start create socket ... ')
local ok, err = sock:connect(host, port)
if not ok then
print("connect create failed: " .. err)
os.exit(1)
end
print('start create header ... ')
local headers = {
{ name = ":method", value = "GET" },
{ name = ":path", value = "/authorization" },
{ name = ":scheme", value = "http" },
{ name = "accept-encoding", value = "gzip" },
}
print('start create opt ... ')
local opts = {
ctx = sock,
recv = sock.receive,
send = sock.send,
preread_size = 1024,
max_concurrent_stream = 100,
}
print('start create http2 ... ')
local client, err = http2.new(opts)
if not client then
print("client create failed: ", err)
os.exit(2)
end
print('start request ... ')
local ok, err = client:request(headers, nil, on_headers_reach, on_data_reach, on_trailers_reach)
if not ok then
print("client:request() failed: ", err)
os.exit(3)
end
sock:close()还有两个问题：
- 如果有 query 参数，是直接按规范写在 path 中吗？类似：
local headers = {
{ name = ":method", value = "GET" },
{ name = ":path", value = "/authorization?a=1&b=2&c=3" },
{ name = ":scheme", value = "http" },
{ name = "accept-encoding", value = "gzip" },
}- 如何获取到返回值呢？如果靠回调函数的话，是否要设置一个全局变量去接收返回值？
