发送 POST 时出现 Python 错误 - 需要类似字节的对象，而不是“str”

Question

我正在编写一个脚本，通过获取开放端口 POST 请求并在此处使用它来打开路由器/调制解调器上的端口，但发送时出现此错误：TypeError: a bytes-like object is required, not 'str' .它应该只发送 POST 请求并打开端口而不是错误。

    url = "http://192.168.0.1/apply_abstract.cgi" # http://192.168.0.1/wan_portforwarding.htm?m=adv
    reqInfo = {
        'action: ui_firewall',
        'httoken: REMOVED FOR SAFETY',
        'submit_button: wan_portforwarding.htm',
        '786434001000: ' + GlobalForwardingName,
        '786433001000: 1',
        '786435001000: ' + GlobalInternalIP,
        '#786437001000: ' + GlobalProtocol,
        '786438001000: ', GlobalLanPort,
        '786439001000: ', GlobalLanPort,
        '786440001000: ', GlobalWanPort,
        '786441001000: ', GlobalWanPort
    }

    sendReq = requests.post(url, data = reqInfo)```

Answer 1

您没有发送 dict 对象，只有字符串，这可能是主要问题，试试这个：

reqInfo = {
    'action': ui_firewall,
    'httoken': 'REMOVED FOR SAFETY',
    'submit_button': wan_portforwarding,
    '786434001000':   GlobalForwardingName,
    '786433001000': 1,
    '786435001000':  GlobalInternalIP,
    '#786437001000': GlobalProtocol,
    '786438001000':  GlobalLanPort,
    '786439001000':  GlobalLanPort,
    '786440001000':  GlobalWanPort,
    '786441001000':  GlobalWanPort
}

sendReq = requests.post(url, data = reqInfo)
