python 3 https 发帖很慢

Question

我有一个脚本，它使用 python 3 和 FancyURLopener 通过 https 登录。所以我这样做:

from urllib.request import FancyURLopener, urlopen
from urllib.parse import urlencode
import re, sys

class SMS:

    login_url = "url1"
    login_act = "url2"
    comp_url = "url3"
    comp_act = "url4"
    LEN = 100

    def __init__(self, phone_num, password):
        self.phone_num = phone_num
        self.password = password
        self.opener = FancyURLopener()
        resp = self.opener.open(SMS.login_url)
        cookie = ""
        for x, y in resp.headers.items():
            if x == "Set-Cookie":
                cookie += y + "; "
        cookie = cookie[:-2]            
        self.opener.addheader("Cookie", cookie)
        print("--login")
        self.login()

    def login(self):
        di = { "action":"", "refid":"", "continuation":"",\
"username":self.phone_num, "password":self.password, "image.x":"45", "image.y":"18"}
        resp = self.opener.open(SMS.login_act, urlencode(di))

    def send(self, to, message):
        print("--sending")
        if len(message) > 100:
            print("Message length too long; Not send.")
            return -1
        resp = self.opener.open(SMS.comp_url).read().decode("windows-1251")
        pattern1 = "<input type=\"hidden\" name=\"daycreditsmsleft\" value=\"(\d+)\""
        pattern2 = "<input type=\"HIDDEN\" name=\"smssenttime\" value=\"(\d+)\""
        post = {"brand":"", "daycreditsmsleft":re.search(pattern1, resp).groups()[0],\
"process":"true", "btnSendSMS.x":"75", "btnSendSMS.y":"23", "model":"0",\
"smssenttime":re.search(pattern2, resp).groups()[0], "remainingChars": str(SMS.LEN - len(message)),\
"reply2inbox":"false", "selReceiverName":"", "txtareaMessage":message, "receiverPhoneNum":to}
        if post["daycreditsmsleft"] == 0:
            print("No more messages; Not send")
            return -1
        resp = self.opener.open(SMS.comp_act, urlencode(post) )

然后我会像这样使用它:

s = SMS("telephone_num", "pass")
s.send(tel, message)

问题是POST请求太慢了。登录需要20多秒。在整个脚本中有 2 个 POST 请求，所以它实际上运行了将近一分钟。如何优化？

我还注意到消息是在程序结束前收到的。

我的猜测是请求中有一些细微的不同，这使得您的服务器需要很长时间来处理请求。

如果你是服务器的编写者，这应该很容易验证。如果不是，您可能必须使用某种跟踪程序，以便您可以查看请求何时从 Python 端完成以及响应何时返回，并将其与来自浏览器的请求进行比较。
