Re: Copy Behavior w RegEx for binary

[Brandon Byars]

Responded on the other thread, but no, binary regexes are not possible. It may be possible to use an inject predicate to do what you're wanting.

Trying to clarify, I'm essentially sending text via tcp/binary, so I was hoping to use the encoded text for regex matching and capture.

I've highlighted base64 here, but we use hex mainly which is why I wrote the custom protocol to convert it to hex.

Is that possible? Just not sure how to configure it for this or what way to approach extending mountebank to support

Thanks

Hi,

Trying to find information on whether its possible to use Regex in binary stubs

i.e. capture elements from the base64 string and use in response

"responses": [

{

"is": "MDMzMzAyNDk1{captured[0]}AzMjM2MzAzMDMwMzAzNTMwMzAzMTMwMzA0NjMyMzM0MzMwMzYzODMxMzIzODQ1MzEzODMwMzAzMjMwMzAzMDMwMzAzMDMwMzAzMDMwMzAzMDMwMzAzMDM4MzEzNjM0MzEzMTMxMzEzMTMxMzEzMTMxMzEzMTMxMzEzMT"

}

"predicates": [ { 

           matches : { "base64Str" : MDMzMzAyNDk1(.{8})AzMjM2MzAzMDMwMzAzNTMwMzAzMTMwMzA0NjMyMzM0MzMwMzYzODMxMzIzODQ1MzEzODMwMzAzMjMwMzAzMDMwMzAzMDMwMzAzMDMwMzAzMDMwMzAzMDM4MzEzNjM0MzEzMTMxMzEzMTMxMzEzMTMxMzEzMTMxMzEzMT

}

} ]

I have written a custom protocol to convert the binary to hex as its easier to work with for us, but concept is the same, just trying to see whether we can do this with built-in mountebank or if I have to expand the scope of the custom protocol

Thanks
