【背景】
之前已经：
【记录】在ssh2可以登陆pcDuino后尝试去用VNC连接并操作pcDuino
现在接着去，用Python的flask去建立web服务器。
【折腾过程】
1.参考：
How to use Python to setup pcDuino as a web server | pcDuino
但是觉得其好像很繁琐的样子。
2.所以去官网：
Welcome | Flask (A Python Microframework)
去参考其：
Installation — Flask 0.10.1 documentation
去安装Flask，但是也觉得很烦。
3.所以直接去试试，在Lubuntu中去安装flask：
先打开Lubuntu中的终端LXTerminal：
然后启动终端之后：
4.再去安装flask：
结果很明显，Lubuntu中没有安装pip：
5.再去先安装pip：

如图：
6.然后再去用pip去安装flask：

如图：
7.然后再去参考官网去写测试代码：
启动LeafPad
拷贝代码：
1 2 3 4 5 6 7 8 9 | from flask import Flaskapp = Flask(__name__)@app.route("/")def hello(): return "Demo webserver using python flask in Lubuntu pcDunino by Crifan Li"if __name__ == "__main__": app.run(host='0.0.0.0', port=80, debug=True) |
然后用Ctrl+V去粘贴代码到Leafpad中：
然后另存为：
然后新建一个叫做develop的文件夹：
然后输入回车，进入该文件夹，然后输入保存的文件名：demoWebserverViaFlask.py，然后再点Save保存:
8.然后回到终端中，切换到对应的develop文件夹，则ls可以看到对应的文件：
然后再去运行：
9.在主机端Win7中，能访问到这个服务器之前，先去确定其pcDuino的ip是多少
可见，是：
192.168.1.107
所以，在Win7中，用（火狐）浏览器去访问此地址：
说明的确用Python的Flask建立的Web服务器，的确可以正常工作了。
对应的，可以看到终端中的输出：
显示出对应的网页的访问。
【总结】
至此，在pcDuino的Lubuntu上，用Python的Flask去建立一个最简单的Web服务器，就完成了。
其中可见：
主要是对于在Ubuntu系统上，去安装Flask，建立Web服务器，相关的操作流程。
其本身，和pcDuino，倒是关系不大。
但是，这也说明了，此处，可以把pcDuino当做一台服务器，可以用此服务器，去做你想要的各种各样的事情了。
