刚接触Python，上篇 《Python入门》第一个Python Web程序——简单的Web服务器 中调试非常不方便，不知道对象详细有什么属性，包括什么值，所以写了一个函数。用于获取对象的属性及属性值
函数代码例如以下：
#调试函数。用于输出对象的属性及属性值 def getAllAttrs(obj): strAttrs = ‘‘ for o in dir(obj): strAttrs =strAttrs + o + ‘ := ‘ + str(getattr(obj,o)) + ‘<br />‘ return strAttrs;
详细应用代码：
import os #Python的标准库中的os模块包括普遍的操作系统功能
from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler #导入HTTP处理相关的模块
#调试函数。用于输出对象的属性及属性值
def getAllAttrs(obj):
strAttrs = ‘‘
for o in dir(obj):
strAttrs =strAttrs + o + ‘ := ‘ + str(getattr(obj,o)) + ‘<br />‘
return strAttrs;
#自己定义处理程序。用于处理HTTP请求
class TestHTTPHandler(BaseHTTPRequestHandler):
#处理GET请求
def do_GET(self):
#页面输出模板字符串
templateStr = ‘‘‘
<html>
<head>
<title>QR Link Generator</title>
</head>
<body>
%s
</body>
</html> ‘‘‘
self.protocal_version = ‘HTTP/1.1‘ #设置协议版本号
self.send_response(200) #设置响应状态码
self.send_header("Welcome", "Contect") #设置响应头
self.end_headers()
self.wfile.write(templateStr % getAllAttrs(self)) #输出响应内容
#启动服务函数
def start_server(port):
http_server = HTTPServer((‘‘, int(port)), TestHTTPHandler)
http_server.serve_forever() #设置一直监听并接收请求
os.chdir(‘static‘) #改变工作文件夹到 static 文件夹
start_server(8000) #启动服务。监听8000端口
输出例如以下：
