Restsharp: IRestResponse content returns “[]”

Question

I am trying to implement a test of my rest api using restsharp, which seems to be a very powerful and easy tool to use for simple tests.

With that said I still have problems getting content from my IRestResponse.

The code goes as following:

...
    [TestMethod]
    public void Testing_Whether_Get_Returns_cellphone()
    {
        // Arrange
        RestClient restClient = new RestClient("http://pseudoUrl/Users?UserId={uid}");       
        //restClient.AddDefaultHeader("headerType1", Guid.NewGuid().ToString());
        //restClient.AddDefaultUrlSegment("uid", "25248896");
        RestRequest restRequest = new RestRequest(Method.GET);
        restRequest.AddQueryParameter("uid", "25248896");
        restRequest.AddHeader("headerType1", Guid.NewGuid().ToString());
        // Act
        IRestResponse restResponse = restClient.Execute(restRequest); // restresponse = "StatusCode: Ok.."
        string response = restResponse.Content; // response = "[]"

        // Assert
        Assert.IsTrue(response.Contains("cellphone"));
    }
...

When testing the above, the statuscode is 200, but content is "[]", even though that when I test it with swagger, I get a nice json-response filled with the wanted content.

As you can see I have tried using both AddDefaultUrlSegment and AddQueryParameter. The last one is the most obvious, I guess?

the following url in swagger is: " http://pseudoUrl/Users?UserId=25248896 " added the header: headerType1 and again - that works perfectly fine.

Can anyone see, what I am doing wrong?

AddQueryParameter with your current inputs is going to add ?uid=25248896 to the URL.

Just put your URL without query http://pseudoUrl/Users into the RestClient constructor and then change the "uid" to "UserId" in AddQueryParameter

[TestMethod]
public void Testing_Whether_Get_Returns_cellphone()
{
    // Arrange
    RestClient restClient = new RestClient("http://pseudoUrl/Users");
    RestRequest restRequest = new RestRequest(Method.GET);
    restRequest.AddQueryParameter("UserId", "25248896");
    restRequest.AddHeader("headerType1", Guid.NewGuid().ToString());
    // Act
    IRestResponse restResponse = restClient.Execute(restRequest); 
    string response = restResponse.Content; // response = "[]"

    // Assert
    Assert.IsTrue(response.Contains("cellphone"));
}
