If you're using GET, you can just map query string parameters directly to parameter names (ie. &id=xxxx) maps to Get(string id) or [Route(person/{id}] and person/xxxx. You don't even need [FromUri]. Your approach works but it's much less expressive for the person consuming the API.

We're using angularJs (1.6.04) and ASP.NET.MVC. The value was passed as is, e.g. I was seeing in the url:

1/sometext

When this text contained / I had problems. The angular.js service implementation was as following:

/**
     * @public   
     * @param {int} attributeId
     * @param {string} criteria
     * @returns {ng.IPromise}
     */
    MatrixTemplatesService.prototype.getAttributeValues = function (attributeId, criteria) {
        var deferred = services.Deferred;


       // Original code

      // services.Http.get("api/matrixTemplates/getAttributeValues/" + id + "/" + criteria);

        let keyValuePair = { Key: attributeId, Value: criteria };
        services.Http.get("api/matrixTemplates/getAttributeValues", 
            { params: keyValuePair }
        )
            .then(function (data) {
                deferred.resolve(data.data);
            });

        return deferred.promise;
    };

So, how I was supposed to code this line (criteria is a plain text at that point)

services.Http.get("api/matrixTemplates/getAttributeValues/" + id + "/" + criteria);

and the receiving line in my API?

Thanks a lot in advance.
