Good afternoon,

I am having trouble understanding what I have configured incorrectly to get a Request match using WithBody. Test below gives 404 when using WithBody and WildcardMatcher or Func matcher.
If I remove the WithBody on the Request then a http OK response occurs.

      [Fact]
        public async Task BodyContentTest()
        {
            var server = FluentMockServer.Start();
            server.Given(Request.Create()
                    .WithPath("/Test")
                    .UsingPost()
                    .WithBody(new WildcardMatcher("access_token")))
                .RespondWith(Response.Create()
                    .WithStatusCode(200)
                    .WithHeader("Content-Type", "text/plain")
                    .WithBody("Result"));

            var client = new HttpClient {BaseAddress = new Uri($"http://localhost:{server.Ports[0]}/Test")};
            var content = new StringContent("access_token=foo", Encoding.UTF8, "application/json");
            var testResponse = await client.PostAsync("/Test", content);
            Assert.Equal(HttpStatusCode.OK, testResponse.StatusCode);
        }

I was able to get a matcher going for body content if I used:

 private static Func<string, bool> StringMatch()
        {
            return b => b.Contains("access_token");
        }

but still unsure why WildcardMatcher or as inline func
WithBody(b=>b.ToString().Contains("access_token")))
did not work.
If anyone could enlighten me that would be great!

When using WildcardMatcher, you should use * as a wildcard character.

Like:

.WithBody(new WildcardMatcher("*access_token*")))
