I'm a beginner for laravel an vuejs, when I am trying to refresh the page I got such error message, this is my code from web file :
Route::get('{path}',"HomeController#index")->where('path','(-a-z0-9_\s)');
Anyone with and idea?
From looking at you Regular Expression, even it it compiled you probably won't find any URI that matches it, so you will get Laravel No Route exception.
You should probably use Brackets [] to setup the range of character and add the + to match that range multiple times to make words or phrase. Use this Regex :
[-a-z0-9_\s]+
The Route codes :
Route::get('{path}',"HomeController#index")->where('path','[-a-z0-9_\s]+');
Or use Brackets inside the Parenthesis :
Route::get('{path}',"HomeController#index")->where('path','([-a-z0-9_\s]+)');
Use https://regex101.com/ to validate your string with Regex the next time
you just need to change your code like this
Route::get('{path}',"HomeController#index")->where('path','[-a-z0-9_\s]+');

I'm trying to use regular expression extractor concept in Jmeter. By using regEx concept I'm able to get the required token id's. And for all I'm using regEx as (.*?). So this is working fine when we have constant prefix and suffix text/values.
But in this case, there is no suffix,
Ex: Key is = #bluerelay.com/a43a816dcdd14873bd5757b3a3709d5c,
ClickHereForImageForm
I want to take the key ID into a variable with using RegEx. I have tried to get it with (.*?) but it didn't work, it returns the full value, not the required part. It'd be excellent if you could give any suggestion.
The source value is:
https://navitus-internal-app.bluerelay.com/#/token/systemadministrator#bluerelay.com/a43a816dcdd14873bd5757b3a3709d5c
The expected result is to extract a43a816dcdd14873bd5757b3a3709d5c from the above URL and put it into a variable.
You can use regex to get last text after / sign
(.*)\/(\w+)
See demo
I m trying to validate the image url using golang code but there is error in regular expression I'm showing my regular expression in this question:-
var validation = regexp.MustCompile("(http(s?):)|([/|.|\w|\s])*\.(?:jpg|gif|png)")
Error:-
unknown escape sequence (and 2 more errors)

\. is an invalid escape sequence. I would suggest you use backticks when defining regular expressions. e.g.
regexp.MustCompile(`^https?://.*\.(jpg|gif|png)$`) // this will just check if the url ends with jpg,gif,png
If you are not using the capture groups, this is a simpler approach. However when parsing or validating URLs, use url.Parse() which provides better validation.
I'm trying to verify substring of a value to match with either of the strings.
I tried the ways as follows :
1) expect(row.getText()).toContain('Håkan Åström' || 'Hakan Astrom')
in this verification the 2nd string is not being checked so throwing fail of the step
2) expect(row.getText()).toBeIn('Håkan Åström','Hakan Astrom')
TypeError: Object # has no method 'toBeIn' - error is seen.
Can any one share the solution that can be used.
Thanks
Try to use .toMatch(RegExp). Your regular expression can match your expected string:
expect(row.getText()).toMatch(/H[aå]kan [AÅ]str[oö]m/)
Lets suppose I have a url like this:
https://www.youtube.com/watch/3e4345?v=rwmEkvPBG1s
What is the best and shorthest way to only get the 3e4345 part?
Sometimes it doesn't contain additional params in ?
I don't want to use any gems.
What I did was:
url = url.split('/watch/')
url = url[1].split('/')[0].split('?')[0]
Is there a better way? Thanks
possibly the safest and best one. use URI.
URI("https://www.youtube.com/watch/34345?v=rwmEkvPBG1s").path.split("/").last

You could do the following and using the match function to find a match based on a regular expression statement. The value at [1] is the first capture from the regular expression. I have included a breakdown from regexper.com to help illustrate what the expression is accomplishing.
You will notice parentheses around the \d+ which are what captures the digits out of the URL when it matches.
url.to_s.match(/\/watch\/(\d+).*$/)[1]
x = "https://www.youtube.com/watch/34345?v=rwmEkvPBG1s"
File.basename(URI(x).path)
=> "34345"
I'm having a problem getting my RegEx to work with my Ruby script.
Here is what I'm trying to match:
http://my.test.website.com/{GUID}/{GUID}/
Here is the RegEx that I've tested and should be matching the string as shown above:
/([-a-zA-Z0-9#:%_\+.~#?&\/\/=]{2,256}\.[a-z]{2,4}\b(\/[-a-zA-Z0-9#:%_\+.~#?&\/\/=]*)([\/\/[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\/\/[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\/\/])*?\/)/
3 capturing groups:
group 1: ([-a-zA-Z0-9#:%_\+.~#?&\/\/=]{2,256}\.[a-z]{2,4}\b(\/[-a-zA-Z0-9#:%_\+.~#?&\/\/=]*)([\/\/[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\/\/[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\/\/])*?\/)
group 2: (\/[-a-zA-Z0-9#:%_\+.~#?&\/\/=]*)
group 3: ([\/\/[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\/\/[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\/\/])
Ruby is giving me an error when trying to validate a match against this regex:
empty range in char class: (My RegEx goes here) (SyntaxError)
I appreciate any thoughts or suggestions on this.
You could simplify things a bit by using URI to deal parsing the URL, \h in the regex, and scan to pull out the GUIDs:
uri = URI.parse(your_url)
path = uri.path
guids = path.scan(/\h{8}-\h{4}-\h{4}-\h{4}-\h{12}/)
If you need any of the non-path components of the URL the you can easily pull them out of uri.
You might need to tighten things up a bit depending on your data or it might be sufficient to check that guids has two elements.
You have several errors in your RegEx. I am very sleepy now, so I'll just give you a hint instead of a solution:
...[\/\/[0-9a-fA-F]....
the first [ does not belong there. Also, having \/\/ inside [] is unnecessary - you only need each character once inside []. Also,
...[-a-zA-Z0-9#:%_\+.~#?&\/\/=]{2,256}...
is greedy, and includes a period - indeed, includes all chars (AFAICS) that can come after it, effectively swallowing the whole string (when you get rid of other bugs). Consider {2,256}? instead.
