使用替换、子字符串替换字符串中的多个值并在 Python 中查找

Question

所以我从我们的 jira 项目中提取问题，我需要在描述中用新格式化的 url 替换 url。 旧描述包含旧的 sharepoint 服务器 URL，因此我需要将它们更改为我们新的在线 Sharepoint url。我决定使用 Python 来使用 atlassian 插件。 这是当前 jira 问题中描述的一个版本：

Good day 

we need a new validation on the External Reference when doing work pads or amending manually when we do refund, it seems that the user that updates this is using Tab or Enter and therefore the payment files fails ,

we need users to be validated while updating refund reference same way as we limited claims payments for updating invoice numbers

thank you 
regards

这就是我从 Jira 提取问题的方式（我的计划是扫描所有问题并进行更新。

from jira import JIRA
import re
jira = JIRA(server=('https://mycompanydev.atlassian.net'),basic_auth=('user', 'password'))
issue = jira.issue("S1-3000")
print("Ticket nr: ", issue)
olddescription = issue.fields.description
newdescription = olddescription

所以我设法用这一行更改了 url 的第一部分：

newdescription = newdescription.replace("http://portal.mycompany.local/mycompany/someproject/_layouts/15/start.aspx#/someproject/Forms/AllItems.aspx?RootFolder=%2Fmycompany%2Fsomeproject%2F", "https://somecompany.sharepoint.com/sites/CCPortal/")

和这一行：

newdescription = newdescription.replace("http://portal.mycompany.local/mycompany/someproject/SitePages/Home.aspx?RootFolder=%2Fmycompany%2Fsomeproject%2F", "https://mycompany.sharepoint.com/sites/CCPortal/")

此代码成功完成并按预期更改了 URL。

现在我需要从字符串“View=”和字符串“FolderCTID=”中删除 url 的末尾我的代码行来执行此操作：

newdescription = newdescription.replace(newdescription[newdescription.find("View=")-1:newdescription.find("]")],"")

和：

newdescription = newdescription.replace(newdescription[newdescription.find("FolderCTID="):newdescription.find("]")], "")

由于某种原因，它只处理前 2 个 URL：结果如下所示：

we need users to be validated while updating refund reference same way as we limited claims payments for updating invoice numbers

如您所见，代码删除了前 2 个“View=”字符串，尾随字符串一直到末尾。

我无法弄清楚我哪里出错了我还尝试将其放入 while 循环并重复代码 5 次以进行测试。

Answer 1

str.find返回找到 substring 的最低索引。 因此，如果newdescription有多个"]" ，大概是因为它包含多个链接，这意味着返回的索引仅对第一个链接是正确的。

str.find还接受一个可选的开始/结束索引来限制搜索，因此您可以使用"View="的索引作为搜索"]"的偏移量：

offset = newdescription.find("View=")
replace_me = newdescription[offset:newdescription.find("]", offset)]
newdescription = newdescription.replace(replace_me, "")
