我也不知道 python

中的 urllib

Answer 1

错误告诉你的是 headers 需要是一个字典，items 是生成键和值的元组对的字典方法。

要使用 requests 发出 POST 请求，您必须

import requests

url = "https://tracking.post.ir/"

h = {
  "User-Agent": "Mozilla/5.0 (Linux; Android 7.0.0; SM-G960F Build/R16NW) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.84 Mobile Safari/537.36"
}

dat = {"test": "test"}

respose = requests.post(url, data=dat, headers=h)

# Do something with response here
