openwrt Python3.6 get or post request url by methods comes urllib

    obj = hashlib.md5((Nonce + CTime + header_key).encode('utf-8'))
    return obj.hexdigest()

headers = {"User-Agent":"test request headers","Nonce": Nonce,"CTime": CTime,"Sign": header_Md5(Nonce,CTime)}
body ={"gwName": "test","gwid": '6699'+uuid.uuid1().hex[-12:], "Password":"123" }
body = parse.urlencode(body).encode('utf-8')
req = request.Request(URL, headers=headers, data=body)  # POST方法
# req = request.Request(url+params)  # GET方法
page = request.urlopen(req).read()
page = page.decode('utf-8')
