使用字典管理请求路径
编写函数，通过url（字典）添加新的请求路径，回调函数实现结果。
url = {
'/': index,
'/test': show_test,
'/demo': show_demo,
'/hello': show_hello,
'/info': show_info,
'/foo': show_foo
}示例：
import json
from wsgiref.simple_server import make_server
def load_file(file_name, **kwargs):
try:
with open('pages/' + file_name, 'r', encoding='utf8') as file:
content = file.read()
if kwargs: # kwargs = {'username':'zhangsan','age':19,'gender':'male'}
content = content.format(**kwargs)
# {username},欢迎回来,你今年{age}岁了,你的性别是{gender}.format(**kwargs)
return content
except FileNotFoundError:
print('文件未找到')
def index():
return '欢迎来到我的首页'
def show_test():
# return json.dumps({'name': 'zhangsan', 'age': 18})
return json.dumps(['zhangsan', 'lisi', 'wangwu', 'jack'])
def show_demo():
return load_file('xxxx.txt')
def show_hello():
return load_file('hello.html')
def show_info():
return load_file('info.html', username='zhangsan', age=19, gender='male')
def show_foo():
return '我是foo'
url = {
'/': index,
'/test': show_test,
'/demo': show_demo,
'/hello': show_hello,
'/info': show_info,
'/foo': show_foo
}
def demo_app(environ, start_response):
path = environ['PATH_INFO']
status_code = '200 OK'
method = url.get(path)
if method:
response = method()
else:
status_code = '404 Not Found'
response = '页面走丢了'
start_response(status_code, [('Content-Type', 'text/html;charset=utf8')])
return [response.encode('utf8')]
if __name__ == '__main__':
httpd = make_server('', 8090, demo_app)
sa = httpd.socket.getsockname()
print("Serving HTTP on", sa[0], "port", sa[1], "...")
httpd.serve_forever()
