1. "su"的加密算法,su是username经过BASE64计算得来的:
def get_encodename(name):
    # name must be string
    username_quote = quote_plus(str(name))
    username_base64 = base64.b64encode(username_quote.encode("utf-8"))
    return username_base64.decode("utf-8")

2.获取sp的值,就是密码rsa的加密值

1.首先访问http://login.sina.com.cn/sso/prelogin.php?entry=weibo&callback=sinaSSOController.preloginCallBack&su=上面的su字符串=&rsakt=mod&checkpin=1&client=ssologin.js(v1.4.18)&_=时间戳,获取json字符串

def get_server_data(su,session,proxy):
    pre_url = "http://login.sina.com.cn/sso/prelogin.php?entry=weibo&callback=sinaSSOController.preloginCallBack&su="
    pre_url = pre_url + su + "&rsakt=mod&checkpin=1&client=ssologin.js(v1.4.18)&_="
    prelogin_url = pre_url + str(int(time.time() * 1000))
    pre_data_res = session.get(prelogin_url, headers=headers, proxies=proxy)
    sever_data = ast.literal_eval(pre_data_res.content.decode("utf-8").replace("sinaSSOController.preloginCallBack", ‘‘))
    return sever_data

2.获取url的post数据的一部分内容

{"retcode":0,"servertime":1526866235,"pcid":"gz-5a7050e9c71bbf284bca688fd7bd24ec57e1","nonce":"WPGNDA","pubkey":"EB2A38568661887FA1w3062882729293E5506350508E7F9AA3BB77F4333231490F915F6D63C55FE2F08A49B353F444AD3993CACC02DB784ABBB8E42A9B1BBFFFB38BE18D78E87A0E41B9B8F73A928EE0CCEE1F6739884B9777E4FE9E88A1BBE495927AC4A799B3181D6442443","rsakv":"1330428213","is_openlock":0,"lm":1,"smsurl":"https:\/\/login.sina.com.cn\/sso\/msglogin?entry=weibo&mobile=18810668312&s=5a68912sabf7e2d399ab4f878dc7","showpin":0,"exectime":27}

"showpin":表示是否需要验证码,1需要,0不需要

这一步为了获取下面几个参数的值

    servertime = server_data["servertime"]
    nonce = server_data[‘nonce‘]
    rsakv = server_data["rsakv"]
    pubkey = server_data["pubkey"]

 然后进行rsa解密,导入rsa模块

def get_password(password, servertime, nonce, pubkey):
    rsa_publickey = int(pubkey, 16)
    key = rsa.PublicKey(rsa_publickey, 65537) #创建公钥
    message = str(servertime) + ‘\t‘ + str(nonce) + ‘\n‘ + str(password) #创建公钥
    message = message.encode("utf-8")
    passwd = rsa.encrypt(message, key) #加密
    passwd = binascii.b2a_hex(passwd) #将加密信息转换为16进制。
    return passwd

最后我们就可以构造post数据进行请求了

def login_no_pincode(name, password, session, server_data, proxy):
    post_url = ‘http://login.sina.com.cn/sso/login.php?client=ssologin.js(v1.4.18)‘

    servertime = server_data["servertime"]
    nonce = server_data[‘nonce‘]
    rsakv = server_data["rsakv"]
    pubkey = server_data["pubkey"]
    sp = get_password(password, servertime, nonce, pubkey)

    data = {
        ‘encoding‘: ‘UTF-8‘,
        ‘entry‘: ‘weibo‘,
        ‘from‘: ‘‘,
        ‘gateway‘: ‘1‘,
        ‘nonce‘: nonce,
        ‘pagerefer‘: "",
        ‘prelt‘: 67,
        ‘pwencode‘: ‘rsa2‘,
        "returntype": "META",
        ‘rsakv‘: rsakv,
        ‘savestate‘: ‘7‘,
        ‘servertime‘: servertime,
        ‘service‘: ‘miniblog‘,
        ‘sp‘: sp,
        ‘sr‘: ‘1920*1080‘,
        ‘su‘: get_encodename(name),
        ‘useticket‘: ‘1‘,
        ‘vsnf‘: ‘1‘,
        ‘url‘: ‘http://weibo.com/ajaxlogin.php?framelogin=1&callback=parent.sinaSSOController.feedBackUrlCallBack‘
    }

    return None, ‘‘, session
