获取post传来的数据

import web

urls = (
	'/CommitMap', 'aa.cc', # 实现aa.py中的cc类
	'/aaa/([^/]*)', 'bbb'  # 也可通过正则来匹配未知参数，这里你要实现bbb类
)

class CommitMap:

	def POST(self):
		#data = web.input()
		#return 'ooo' + str(''.join(data.keys()))
		data = web.data()
		return 'hhh' + str(data)

if __name__ == '__main__':
	app = web.application(urls, globals())
	app.run()

web.input(),获取url参数，返回值是类似于字典的key-value对,可以用于GET和POST。
web.data(),获取实体正文，返回值是一个字符串，只能用于POST。

实现文件上传: http://webpy.org/cookbook/storeupload.zh-cn

urls = ('/upload', 'Upload') # 前者表示链接中的参数，后者表示要实现的类

class Upload:
    def GET(self):
            web.header("Content-Type","text/html; charset=utf-8")
            return """<html><head></head><body>
    <form method="POST" enctype="multipart/form-data" action="">
    <input type="file" name="myfile" />
    <br/>
    <input type="submit" />
    </form>
    </body></html>"""

    def POST(self):
        x = web.input(myfile={})
        filedir = '/path/where/you/want/to/save' # change this to the directory you want to store the file in.
        if 'myfile' in x: # to check if the file-object is created
            filepath=x.myfile.filename.replace('\\','/') # replaces the windows-style slashes with linux ones.
            filename=filepath.split('/')[-1] # splits the and chooses the last part (the filename with extension)
            fout = open(filedir +'/'+ filename,'wb') # creates the file where the uploaded file should be stored
            fout.write(x.myfile.file.read()) # writes the uploaded file to the newly created file.
            fout.close() # closes the file, upload complete.
        raise web.seeother('/upload')

上面的GET方法实现通过手动在页面上操作的输入，可以写爬虫请求实现输入代替（运行上面再运行下面）：

url = 'http://localhost:8080/Upload'

files = {'myfile': open('D:\\..\\...', 'rb')} # 注意'myfile'这个名字要与上面对应

res = requests.post(url, files=files)
print res.text
