问题描述

大家好,

我是初级开发人员,所以我还没有选择正则表达式(> o<)。

在目前的情况下,我想检查SharePoint URL是否有效。
在验证sharepoint url之前,我想验证它是否是正确的aspx url ...

例如:




























< tr style ="height:15pt"height = 20>


















http:// localhost:8181 / Test_ASPX_To_HTML / test0.aspx (有效)
http://localhost/Test_ASPX_To_HTML/test1.aspx (有效)
https://www.helloworld.com/Test_ASPX_To_HTML/test2.aspx (有效)
https://www.helloworld.co.jp/ Test_ASPX_To_HTML / test3.aspx (有效)
http://www.helloworld.org.hk/Test_ASPX_To_HTML/test4.aspx (有效)
https://www.helloworld.tv:1233/Test_ASPX_To_HTML/test5.aspx (有效)
https:// localhost:8181 / Test_ASPX_To_HTML / test6.aspxx (无效)
https://localhost:8181/Test_ASPX_To_HTML/test7.asp (无效)
https:// localhost:8181 / Test_ASPX_To_HTML / test8.asax (无效)
https:// localhost:8181 \Test_ASPX_To_HTML \ test9.asax (无效)
http://123@123.aspx (无效)
HTTP://!〜!@#$%^^&放大器; *(((((((((((((的.aspx (无效)
http:// localhost:8181 / Test_ASPX_To_HTML / test10.aspx θA = 1 (有效)
http:// localhost :8181 / Test_ASPX_To_HTML / test11.aspx?a = 2& b = 3 (有效)
http://www.test.net/Test_ASPX_To_HTML/test12.aspx?a=2&b=3&c=4 (有效)
http://www.test.net\Test_ASPX_To_HTML\test13.aspx?a=2&b=3&c=4 (无效)
www.test.net/Test_ASPX_To_HTML/test14.aspx?a=2&b=3&c=4 (无效)
ftp://www.test.net/Test_ASPX_To_HTML/test15.aspx (无效)
HTTP://www.test.net\Test_ASPX_To_HTML\test16.aspx A = 2和b = 3和C = 4 (无效)

并且它必须没有任何无效的字符。等。

一一

我的简单编码如下:

In current situation, I want to check SharePoint URL is valid or not.
Before verify  the sharepoint url, I want to verify it is correct aspx url...

For example:

http://localhost:8181/Test_ASPX_To_HTML/test0.aspx (Valid)
http://localhost/Test_ASPX_To_HTML/test1.aspx  (Valid)
https://www.helloworld.com/Test_ASPX_To_HTML/test2.aspx (Valid)
https://www.helloworld.co.jp/Test_ASPX_To_HTML/test3.aspx (Valid)
http://www.helloworld.org.hk/Test_ASPX_To_HTML/test4.aspx (Valid)
https://www.helloworld.tv:1233/Test_ASPX_To_HTML/test5.aspx (Valid)
https://localhost:8181/Test_ASPX_To_HTML/test6.aspxx  (Invalid)
https://localhost:8181/Test_ASPX_To_HTML/test7.asp  (Invalid)
https://localhost:8181/Test_ASPX_To_HTML/test8.asax  (Invalid)
https://localhost:8181\Test_ASPX_To_HTML\test9.asax  (Invalid)
http://123@123.aspx  (Invalid)
http://~!@#$%^^&*(((((((((((((.aspx  (Invalid)
http://localhost:8181/Test_ASPX_To_HTML/test10.aspx?a=1  (Valid)
http://localhost:8181/Test_ASPX_To_HTML/test11.aspx?a=2&b=3 (Valid)
http://www.test.net/Test_ASPX_To_HTML/test12.aspx?a=2&b=3&c=4 (Valid)
http://www.test.net\Test_ASPX_To_HTML\test13.aspx?a=2&b=3&c=4 (Invalid)
www.test.net/Test_ASPX_To_HTML/test14.aspx?a=2&b=3&c=4  (Invalid)
ftp://www.test.net/Test_ASPX_To_HTML/test15.aspx  (Invalid)
http://www.test.net\Test_ASPX_To_HTML\test16.aspx?a=2&b=3&c=4 (Invalid)

And it must not have any invalid char. etc.




My simple coding as follows:

if (strTargetASPX.Substring(0 ,4)。ToLower()。Equals(" http" )&&

if (strTargetASPX.Substring(0, 4).ToLower().Equals("http") &&

strTargetASPX.Substring(strTargetASPX .Length - 4,4).ToLower()。Equals(" aspx" )&& // Wrong

    strTargetASPX.Substring(strTargetASPX.Length - 4, 4).ToLower().Equals("aspx") && //Wrong

strTargetASPX.IndexOf("!" )< 0&&

                            strTargetASPX.IndexOf("!") < 0 &&

strTargetASPX.IndexOf(" @" ; )< 0&&

                            strTargetASPX.IndexOf("@") < 0 &&

strTargetASPX.IndexOf("#" )< 0&&

                            strTargetASPX.IndexOf("#") < 0 &&

strTargetASPX.IndexOf(" $" )< 0&&

                            strTargetASPX.IndexOf("$") < 0 &&

strTargetASPX.IndexOf(" ^" )< 0&&

                            strTargetASPX.IndexOf("^") < 0 &&

strTargetASPX.IndexOf(" *" )< 0&&

                            strTargetASPX.IndexOf("*") < 0 &&

strTargetASPX.IndexOf("(&)< 0&&

                            strTargetASPX.IndexOf("(") < 0 &&

strTargetASPX.IndexOf(")" )< 0&&

                            strTargetASPX.IndexOf(")") < 0 &&

strTargetASPX.IndexOf(" - " )< 0&&

                            strTargetASPX.IndexOf("-") < 0 &&

strTargetASPX.IndexOf(" +" )< 0&&

                            strTargetASPX.IndexOf("+") < 0 &&

strTargetASPX.IndexOf( @" \" )< 0&&

                            strTargetASPX.IndexOf(@"\") < 0 &&

strTargetASPX.IndexOf(" \"" )< 0&&

                            strTargetASPX.IndexOf("\"") < 0 &&

strTargetASPX.IndexOf(" ;;" )< 0&&

                            strTargetASPX.IndexOf(";") < 0 &&

strTargetASPX.IndexOf(" |" )< 0&&

                            strTargetASPX.IndexOf("|") < 0 &&

strTargetASPX.IndexOf(" [" )< 0&&

                            strTargetASPX.IndexOf("[") < 0 &&

strTargetASPX.IndexOf("]" )< 0&&

                            strTargetASPX.IndexOf("]") < 0 &&

strTargetASPX.IndexOf(" {" )< 0&&

                            strTargetASPX.IndexOf("{") < 0 &&

strTargetASPX.IndexOf("}" )< 0&&

                            strTargetASPX.IndexOf("}") < 0 &&

strTargetASPX.IndexOf("`" )< 0

                            strTargetASPX.IndexOf("`") < 0

{

//做点什么

      //Do something

}

我不确定上面的 检查是否完全正确(至少不能通过子串检查aspx,它与aspx不匹配?a = 1& b = 2等。)因此,我想通过正则表达式获得有关最佳实践的建议。

你能帮帮我吗?

And I’m not sure the above checking is exactly correct or not (at least cannot check aspx by using Substring, it cannot match the aspx?a=1&b=2 etc.), therefore, I would like to get your advice for best practices with regular expressions.

Could you please help me?
