In Asp.Net core Odata, how to prevent filter string from replacing text passed

Question

I am passing an odata query as below

http://localhost:5000/odata/Levels?$filter=contains(Code, '+14')

However when this lands in my controller I see that the filter object received is being replaced as

{contains(Code, ' 14')}

As you can see +14 is being replaced 14 where + is replaced with a space due to which my query is failing. How can I fix this issue?

Replace the + with %2B , then the odata query like this:

http://localhost:5000/odata/Levels?$filter=contains(Code, '%2B14')

Answer 2

Try it like this:

http://localhost:5000/odata/Levels?$filter=contains(Code, encodeURIComponent('+14'))

I don't know how you generate the rest of the URI but you should replace +14 with an encoded representation before sending it the the server.
