1. 如何实现HTTPS链接？

#function: https connection test example
#input: user:     user name
#       password: the user login password
#       host:     the host name 
#output: none
#return: the result description 
def user_login(hostname, user, password):
    conns = httplib.HTTPSConnection(hostname, 443)
    strMethod = '/secret/login/cs?password=' + password + '&username=' + user
    conns.request('GET',  strMethod, 
                            headers = {host,
                                     "User-Agent": "User-Agent: Mozilla/4.0 (compatible; MS IE 6.0; EIS iPanel 2.0;(ziva))",
                                     "Accept-language":"zh-cn",
                                     "Accept-Encoding":"gzip, deflate",
                                     "Accept": "application/xml",
                                     "Connection": "keep-alive"})
    res_s = conns.getresponse()
    status = res_s.status
    ret = res_s.read()
    print 'ret: ', ret
    if( status != 200 ):
        print 'status: ', status
        return ''
    else:
        return ret
    conns.close()

如果字符串有UTF-8中文字符，如何写入文件？

错误的写法：

#function: test file write
#input: file_name: the file name
#       strWrite:  the written string
#output: none
#return: none
def test_file_write(file_name, strWrite)
   stream_file = file(file_name, 'w')
   stream_file.write(strWrite)
   stream_file.close()

正确的写法：

#function: test file write
#input: file_name: the file name
#       strWrite:  the written string
#output: none
#return: none
import codecs

def test_file_write(file_name, strWrite)
   stream_file = codecs.open(file_name, 'w', 'UTF-8')
   stream_file.write(strWrite)
   stream_file.close()

3. HTTP请求中有特殊字符，如何发送HTTP请求？

#function: test http request when the request includes special characters
#input: host: the host name
#       user: the user name
#       password: the user login password
#       verification: the verfication codes
#output: none
#return: none 
def test_http_connection(hostname, user, password, verification):
    conns = httplib.HTTPSConnection(hostname, 443)
    # error coding
    # strMethod = 'secret/login/cs?username=' + user + '&password=' + password + '&verify_code=' + verification
    strMethod = 'secret/login/cs?' + urllib.urlencode({'username':user, 'password':password, 'verify_code':verification})
    print 'method: ', strMethod
    conns.request('GET',  strMethod, 
                            headers = {"Host": hostname,
                                     "User-Agent": "User-Agent: Mozilla/4.0 (compatible; MS IE 6.0; EIS iPanel 2.0;(ziva))",
                                     "Accept-language":"zh-cn",
                                     "Accept-Encoding":"gzip, deflate",
                                     "Accept": "application/xml",
                                     "Connection": "keep-alive"})
    res_s = conns.getresponse()
    status = res_s.status
    ret = res_s.read()
    print 'ret: ', ret
    conns.close()
