Web API whitespace parameter value being converted to null

Question

I have a simple web API service. There are about 10 different GET actions and these return a JSON output of various database records based on the input parameters.

For one particular endpoint a single space, ' ' should be a valid argument but this is being converted to null. Is there a way around this?

For example the URL is: http://localhost:1234/DataAccess/RetrieveProductData?parameterOne=null&parameterTwo=574&problemParameter=%20&parameterThree=AB12

Within the controller action I can see the following:

int? parameterOne => null
string parameterTwo => "574"
string problemParameter => null
string parameterThree => "AB12"

Is there any way to actually get:

string problemParameter => " "

Or is this not possible?

Answer 1

You should do it in the client app. Do you want to deserialize it on Android?
