Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

RMHttp is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod 'RMHttp'

Installation

Run the following command in your Terminal

$ pod install

Usage

HTPP Methods

HTTP Methods are declared in public enum RMHttpMethod.

GET, POST , DELETE , PUT , PATCH

Parameter Encoding

Encoding are declared in public enum Encoding

URLEncoding
JSONEncoding

Serialization

JSONObject - a representation of Dictionary<String, Any>

{
	"data" : "value",
	"isBoolean" : true,
	"list": [
		"object1",
		"object2"
	]
}

JSONArray - a representation of [Dictionary<String, Any>]

[
	{ "data1" : "value1"},
	{ "data2" : "value2"},
	{ "data3" : "value3"},
]

String
Any String respresentation (e.g HTML String, XML String, Plain Text)

Building Request

Building request with parameters from Dictionary type
let params = [
	"string":"Ipsum",   // String
	"number": 100,      // Number
	"boolean":true      // Boolean
] as [String : Any]

let urlString = "https://httpbin.org/get"
let request = RMRequest(urlString, method: .GET(.URLEncoding), parameters: params, hearders: nil)
Building request with parameters from RMParams container

URL query representation names[]=lorem&names[]=ipsum&names[]=dolor&

let lorem = RMParams(key: "names[]", value: "lorem")
let ipsum = RMParams(key: "names[]", value: "ipsum")
let dolor = RMParams(key: "names[]", value: "dolor")
let params = [lorem, ipsum, dolor]

let urlString = "https://httpbin.org/post"
request = RMRequest(urlString, .GET(.URLEncoding), params, nil)
return request

Chained Response Handlers

Expecting Array object Response
RMHttp.JSON(request: request) { (response:JSONArray?, error) in
	guard error == nil else {
		self.title = "Response Error"
		self.activity.stopAnimating()
		self.textView.text = "\(err)"
		return
	}
	self.activity.stopAnimating()
	if let data = response {
		self.title = "Response Sucess"
		self.textView.text = "\(data)"
	}
}
Expecting JSON object Response
RMHttp.JSON(request: request) { (response:JSONObject?, error) in
	guard error == nil else {
		self.title = "Response Error"
		self.activity.stopAnimating()
		self.textView.text = "\(err)"
		return
	}
	self.activity.stopAnimating()
	if let data = response {
		self.title = "Response Sucess"
		self.textView.text = "\(data)"
	}
}

Generic method that return HTTP response has parameter data that comply to RMHttpProtocol (e.g JSONObject, JSONArray, String, )

public class func JSON<T:RMHttpProtocol>(request: RMRequest, completionHandler: @escaping Handler<T>)

FORM-DATA

Add fields from dictionary type
let params =  [
	"name":"lorem", 
	"lastName":"ipsum"
]
let urlString = "https://httpbin.org/post"
let request = RMRequest(urlString, .POST(.FomDataEncoding), params, nil)
return request
Add file

See Media Types

let request = RMRequest(url: URL(string: urlString)!)
request.addForm(field: "file", file: imgData, fileName: "image.jpeg", mimeType: "image/jpeg")
request.setHttp(method: .POST(.FomDataEncoding))
return request
Or manually add field
let request = RMRequest(url: URL(string: urlString)!)
request.addForm(fieldName: "field1", value: "lorem ipsum")
request.addForm(fieldName: "field2", value: "sit dolor amet")
