发送http2请求时，request close

[NICK-DUAN]

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：

1. 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" },
      }

2. 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？

Try to enable debug log in your nginx.conf and see whether there are some logs in your error.log.

For questions:

1. Yep, the querystring should be written in :path
2. The status code is in the :status pseudo header

请问这个问题解决了吗？
