Python 在人类可读的字符串中使用 GsmModem 读取 ussd 响应（en）

Question

我正在使用 gsmmodem 包，并试图从我发送的 USSD 代码中获得响应。 USSD 代码执行工作正常，但响应格式不正确（非人类可读）我想以可读格式获取它。

请在此处检查代码

from __future__ import print_function
import logging
PORT = 'COM11'
BAUDRATE = 921600
USSD_STRING = '*111#'
PIN = None # SIM card PIN (if any)

from gsmmodem.modem import GsmModem

def main():
    print('Initializing modem...')
    modem = GsmModem(PORT, BAUDRATE)
    modem.connect(PIN)
    modem.waitForNetworkCoverage(10)
    print('Sending USSD string: {0}'.format(USSD_STRING))
    response = modem.sendUssd(USSD_STRING) # response type: gsmmodem.modem.Ussd
    print('USSD reply received: {0}'.format(response.message))
    if response.sessionActive:
        print('Closing USSD session.')
        # At this point, you could also reply to the USSD message by using response.reply()
        response.cancel()
    else:
        print('USSD session was ended by network.')
    modem.close()

if __name__ == '__main__':
    main()

您得到的是gsm hexadecimal类型的答案。 因此，您必须将 response.message 字符串解码为正确的格式，然后以人类可读的格式（如utf-8 encode 。

所以，经过

response = modem.sendUssd(USSD_STRING)

写：

ussd_message = unicode(response.message.decode('hex'), 'utf-16-be').encode('utf8')
print('USSD reply received: {0}'.format(ussd_message))
