HTTP/2 POST test using curl library

Test environment

• Architecture: x86_64
• OS: Ubuntu 20.04

Test scenario

client -> server: HTTP/2 GET /longPolling  (Stream-1)
server -> client: Header response
server -> client: Dummy data
server -> client: (Stream hold for 10 seconds)
...
after 7 seconds
...
client -> server: HTTP/2 POST /post  (Stream-3)
server -> client: Header response
server -> client: (Stream hold for 5 seconds)
client -> server: Send post data (100 bytes)
client -> server: Send post data (100 bytes)
...

Simple test server code (node.js, tested with v14.17.5 LTS version)

• index.js

HTTP/2 POST test client code

• h2post.c

Prepare

Clone this repository and update submodules. (nghttp2, curl)

$ git clone https://github.com/webispy/h2curl.git
$ cd h2curl
h2curl$ git submodule update --init

Curl library version

abnormal test case - c4e6968

cd externals/curl
curl$ git reset --hard
curl$ git clean -df
curl$ git checkout c4e6968

normal test case - 842f73d

cd externals/curl
curl$ git reset --hard
curl$ git clean -df
curl$ git checkout 842f73d

Run sample HTTP/2 server

In the server directory, there is a sample server program written in node.js for testing.

$ cd server
server$ npm install
server$ npm start

Build and run sample POST example

The test program used the http2-upload.c file provided in the libcurl example with some modifications.

Executing the commands below builds the nghttp2 library and curl library and then builds the example application.

$ mkdir build && cd build
build$ cmake ..
build$ make

And in order to access the data file to be transmitted when executing the example, you need to copy the dummy.dat file to the directory to be executed.

build$ cp ../dummy.dat .
build$ ./src/h2post

Test result
