GRequest

An HTTP request library written in Swift.

Basic Usage

Be simple, as it should be:

Request("https://api.github.com/repos/lingoer/SwiftyJSON/issues").get{
  response in
  println(response.content)//HTTP Body as NSData
}

If you need more infomation:

Request("https://api.github.com/repos/lingoer/SwiftyJSON/issues").get{
  response in
  println(response.headers)
  println(response.MIMEType)
  println(response.statusCode)
  println(response.encoding)
  println(response.error)
  println(response.content)//HTTP Body as NSData
  println(response.string)//HTTP Body as String
  println(response.object)//HTTP Body as Deserialized Custom Object, Default is NSData. See Below for more info
}

Use .query() to pass parameters for GET methods

Request("www.example.com/api").query(["labels":"discuss"]).get{
  response in
}

As for POST:

//This will encode body as application/x-www-form-urlencoded
Request("http://www.example.com").formBody(["key":"value"]).post{
  response in
}
//This will encode body as application/json
Request("http://www.example.com").jsonBody(["key":"value"]).post{
  response in
}
//You can custom your HTTP Body to POST, with Content-Type provided after it.
Request("http://www.example.com").body(customBodyData, typeString:"application/json; charset=utf-8").post{
  response in
}

More:

Request("http://www.example.com").head{
  response in
}
Request("http://www.example.com").put{
  response in
}
Request("http://www.example.com").delete{
  response in
}
Request("http://www.example.com").patch{
  response in
}

Instances And Chainnings

A Request is in fact a GRequest<T>

It's typealias Request = GRequest<NSData> as default.

And a GRequest is a Generic class specifiying the behavior of the response.

Most methods returns an instance of the GRequest to make chains.

For example .path():

Request("https://api.github.com").path("/repos/lingoer/SwiftyJSON/issues").get{
  response in
}

Response Deserialization

As for the response behavior.

It's mostly about Response Deserialization:

Request("https://api.github.com/repos/lingoer/SwiftyJSON/issues").query(["labels":"discuss"]).get{
  (response:GResponse<JSONValue>) in
  println(response.object)//It's JSON Now
}

Note for more infomation about the JSONValue, see SwiftyJSON

If you need something.Just specify it!

Request("https://www.google.com/images/srpr/logo11w.png").get{
  (response:GResponse<UIImage>) in
  let image:UIImage = response.object!
}

If you don't want to do that every time:

let client = GRequest<JSONValue>("http://api.example.com")
client.path("/path/to/resource").get{
  response in
  println(response.object) //Its JSON Now
}

Extensibility

You can add your custom implementation of your Model deserialization.

By extentions conform protocol: ResponseDeserialization

extension CustomModel:ResponseDeserialization{
  class func convertFromData(data:NSData!) -> (CustomModel?, NSError?)
}

GRequest<CustomModel>("http://api.example.com").get{
  response in
  let model:CustomModel! = response.object
}
