1. 下载

$ mkdir easywsclient
$ git clone
$ cd easywsclient

2. example-server的启动

$ node example-server.js
module.js:340
    throw err;
          ^
Error: Cannot find module 'ws'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)
    at require (module.js:380:17)
    at Object. (/opt/websocket/easywsclient/easywsclient/example-server.js:17:23)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)

解决办法:
$ sudo npm install -g ws
ws@1.0.1 /usr/local/lib/node_modules/ws
?”?”??”? options@0.0.6
?””?”??”? ultron@1.0.2

$ sudo npm install

3. example-client编译

命令行方式编译:
# 直接这样用会报错
# Build and launch the client:
$ g++ -c easywsclient.cpp -o easywsclient.o
$ g++ -c example-client.cpp -o example-client.o
$ g++ example-client.o easywsclient.o -o example-client
$ ./example-client

# 用这个版本:
# ...or build and launch a C++11 client:
$ g++ -std=gnu++0x -c easywsclient.cpp -o easywsclient.o
$ g++ -std=gnu++0x -c example-client-cpp11.cpp -o example-client-cpp11.o
$ g++ example-client-cpp11.o easywsclient.o -o example-client-cpp11
./example-client-cpp11

# 或者直接
$ make
 

4. 测试运行

$ node example-server.js 
Listening on port 8126...

$ ./example-client
easywsclient: connecting: host=localhost port=8126 path=/foo
Connected to: ws://localhost:8126/foo
>>> galaxy
>>> world
