如何在Xamarin和Windows Phone中创建RESTful Web服务？

Question

I am currently trying to find a solution on how to create (not consume!!!) a RESTful service with Xamarin for Android and on Windows Phone. I already searched for it, but only found libraries and solutions on how to consume a RESTful webservice on those platforms. Do you know any good library to create a webservice on those platforms or any hints on how to implement a simple werbservice (not using ASP.NET)?

TIA Octo

The Xamarin.NET and WinRT frameworks (and their package ecosystems) have pretty comprehensive support for web services etc. from a client perspective, but not so much if you want to act as the host. You can't install something like webapi or signalr host into a PCL, or even the native platform projects.

Based on your clarification comments, I would suggest one of the two approaches below. I will assume that the RESTful requirement is more of a "nice to have", and the "calling methods with parameters and getting results" is the priority.

1. Make the mobile apps clients too - remove the hosting requirement from the mobile devices by adding a hub on another server with the full .NET profile. Both your mobile apps and your "test runner" connect to this and the hub routes the messages between them. SignalR would handle this easily. This option is not at all RESTful and requires an additional server, but is quick to get up and running and will easily support your desire to pass json messages back and forth.

2. Go lower level - Use sockets to facilitate communication directly between the mobile devices and "test runner". The mobile devices can open sockets for listening, and your "test runner" connects to them direct. Again, not RESTful and a bit more involved - you need to define a (hopefully) simple protocol (eg {length of type name}{type name}{length of payload}{payload}) and use that to send send and receive json - but it avoids needing a middle machine for routing.
