我正在尝试缩短上的链接比特.do使用Python或Postman。 bit.do url shortener form 在Chrome中，一切正常。但不是Python/Postman。我得到了这个页面，但是只有一个错误，但是来自Chrome的请求和我试图使之看起来一样。 使用chromedev工具捕获了两个POST请求，它们都被命名为url-shortener.pl。 以下是这些请求（因此，我被迫不使用来自URL缩写器的链接，所以我不得不避开它们）：

首先我试着和邮递员联系。参数： postman post request parameters 标题： postman post request headers 响应预览： postman response preview 结果：错误：无效的url。请输入有效的url地址。 然后我切换到Python并尝试处理请求。你知道吗

错误site2:无法创建短链接。请联系我们了解API用法。你知道吗

我希望在HTML响应中得到缩短的链接。有人能解释一下我的请求有什么问题吗？你知道吗

这似乎是最小的工作代码。你知道吗

它需要头'X-Requested-With'，因为它是AXAJ/XHR请求。你知道吗

它需要permasession，但首先GET不发送它，所以它可能是用JavaScript在页面上生成的。但它对我来说一直都是一样的permasession。你知道吗

也许以后它需要新的/新鲜的permasession

" site2 "中有空格

import requests

headers={
    'X-Requested-With': 'XMLHttpRequest', # need it
}

data = {
    'action': 'shorten',
    'url': 'https://onet.pl',
    'url2': ' site2 ', # need spaces 
    'url_hash': None,
    'url_stats_is_private': 0,
    'permasession': '1555801674|ole2ky65f9', # need it
}

r = requests.post('http://bit\.do/mod_perl/url-shortener.pl', headers=headers, data=data)

print(r.status_code)
print(r.json())

它在启动时不需要requests.Session()或User-Agent或GET请求。你知道吗

编辑：值1555801674在'permasession': '1555801674|ole2ky65f9'是当前日期和时间的时间戳。你知道吗

import datetime

datetime.datetime.fromtimestamp(1555801674)

datetime.datetime(2019, 4, 21, 1, 7, 54)

可能ole2ky65f9也是时间戳，但作为缩短值。你知道吗
