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
}
