Replace EasyHttp with RestSharp

[ithielnor]

There is no extra dependency on Json in RestSharp.

Breaking Change: removed AmountInDecimal from ProcessPaymentRequest.

Just realized that I didn't redo the serialization on the domain. Maybe we need to use the default Xml libraries instead of RestSharp's implementation.

These 2 PR's are interesting. I should get time soon to run these through several projects unit tests and integration tests to try and spot any issues with the swap over.

Are you using this in a project that is live? Or are you desperately waiting on updated nuget packages :)

[ithielnor]

I'm working on a new features for an existing project that we are converting to Spreedly. Nothing live yet.

I'm gonna see if I can modify these PRs to use System.Xml.Serialization instead of RestSharp.Serialize as you've got a lot of attribute mapping which could be hard to convert to RestSharp.

[philjones88]

Yeh. I wanted clean C#, hence the attributes. The original names from the spreedly API aren't very C# friendly with underscores etc. Is there not something similar in RestSharp?

[ithielnor]

Yes, but only with one attribute: SerializeAs and they don't support for ignoring properties.

Regardless, I've created a RequestWrapper which uses the system XmlSerializer. So long as all requests are created with RequestWrapper instead of RestRequest it should be good.

All tests are passing, and I've confirmed I can create and redact gateways using the web sample. I haven't tested payments on the sample yet as I have to configure a public site to test it on.

[ithielnor]

Just tested payments and they are working too.
