格式化表单数据？

Question

我需要将下面的表单数据转换为稍微不同的格式才能正确提交。

我有这个表格数据。

PaReq:eJxdUt1ugjAYvfcpyB6AlvpTMLUJG1vmEp2Z7mKXpHRIVMBSBvr0a9FatAlJz/lO6en5PrLZCs6j

想要的格式：

PaReq=eJxdUt1ugjAYvfcpyB6AlvpTMLUJG1vmEp2Z7mKXpHRIVMBSBvr0a9FatAlJz%2FlO6en5PrLZCs6j%0D%0ANWe14HTgOGTBqypOuZMls6cydrGHgwn2UOA%2F6bISrMIvfrzsFfrjosqKnHoudBEBBpryggu2jXNp%0D%0ACEXF7Pg8X9JRgAIICbhCWz9wMY%2Boj%2FEYDyfwugi40FaWxwdOPyJnXRZCVgR02JZZUedSnKiPJgQY%0D%0AYMu12NOtlOUUgKZp3N%2BikGUsRbF3WeHWO0CAVphXgMdnkFWtiap%2FY5sldBGFjf1Yuzzv0PL8evrc%0D%0ApDMCtMLqk1hyiqCHoT%2F0HIimCE%2FHmICO78V10OapNxy5QaDiukBbL7WT8CbSmj7VS6QWgufMRGKQ%0D%0AFfC2LHKuzqg%2B3vY9v7xidBg5VTcryqfGt4QeAyEv73c9Z1J1LwxZ%2BtakbbhOfr6h9sjC65rpSehE%0D%0Ad4Yy1TXkQb9zlNkWEmD%2Br642A6n71A0vHRBwP9j%2F7TDLBQ%3D%3D%0D%0A&TermUrl=https%3A%2F%2Fwww.footpatrol.co.uk%2Fcheckout%2F3d&MD=

我试过了，但格式似乎与我需要正确提交的格式不同。代码：

    import urllib.parse

print(urllib.parse.quote_plus('''PaReq:eJxdUt1ugjAYvfcpyB6AlvpTMLUJG1vmEp2Z7mKXpHRIVMBSBvr0a9FatAlJz/lO6en5PrLZCs6j

可以用 python 获得吗？我需要做什么才能达到预期的最终结果？

Answer 1

如果您的参数由换行符分隔，您可以使用 splitlines 方法获取参数列表，并在每个项目上使用 re.split 获取包含名称、值的列表。
然后对每个名称和值应用 quote_plus，对它们应用 '='.join，对所有参数应用 '&'.join。

import urllib.parse
import re

data = '''PaReq: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

MD:'''

data = [re.split(':(?!//)', line) for line in data.splitlines()]
data = '&'.join('='.join(urllib.parse.quote_plus(i) for i in l) for l in data)

如果您的数据被任意换行分割，您可以加入这些行并按名称分割。然后 zip 名称和值，引用并加入。

data = ''.join(data.splitlines())
data = zip(['PaReq', 'TermUrl', 'MD'], re.split('PaReq:|TermUrl:|MD:', data)[1:])
data = '&'.join('='.join(urllib.parse.quote_plus(i) for i in l) for l in data)

如果要保留换行符，请仅使用第二个代码片段中的最后两行。
