Send HTTP requests from Kitura

KituraRequest

Warning: This is work in progress

A module for sending HTTP requests in IBM Kitura based applications. It wraps KituraNet ClientRequest class and exposes a familiar interface known from Alamofire.

TODO:

• !! Add URL parameter encoding
• !! Add JSON parameter encoding
• !! Multipart form data parameter encoding
• !! Make tests run on Linux
• !! Write tests to check if resulting ClientRequest is properly initialised
• Add synchronus interface
• Add async interface
• Write instructions
• Switch back to depend on IBM Kitura-net

Installation

To install KituraRequest add following line to Dependencies in Package.swift:

.Package(url: "https://github.com/IBM-Swift/Kitura-Request.git", majorVersion: 0)

Currently Swift 3.0 Release is supported

Usage

API of KituraRequest should feel familiar as it closely maps the one of Alamofire.

Creating a request

To create a request object simply call

KituraRequest.request(.get, "https://httpbin.org/get")

Request parameters and parameters encoding

You can also create a request with parameters by passing [String: Any] dictionary together with an encoding method:

KituraRequest.request(.post,
                      "https://httpbin.org/post",
                      parameters: ["foo":"bar"],
                      encoding: JSONEncoding.default)

KituraRequest.request(.post,
                      "https://httpbin.org/post",
                      parameters: ["foo":"bar"],
                      encoding: URLEncoding.default)

KituraRequest.request(.post,
                      "https://httpbin.org/post",
                      parameters: ["foo":"bar"],
                      encoding: MultipartEncoding([
                        BodyPart(key: "file", data: data, mimeType: .image(.png), fileName: "image.jpg")
                    ]))

Currently URLEncoding, JSONEncoding and MultipartEncoding encodings is supported by default.

URLEncoding encodes parameters as URLs query.
JSONEncoding converts parameters dictionary to JSON and appends it to request's body.
MultipartEncoding generates multipart http body from passed parameters and appends it to request's body.
When encoding parameters as JSONEncoding or MultipartEncoding appropriate Content-Type header is set.
To create custom parameter encoding extend any class or struct with Encoding protocol.

Headers

To set headers in the request pass them as [String: String] dictionary as shown below:

KituraRequest.request(.get,
                      "https://httpbin.org/get",
                      headers: ["User-Agent":"Awesome-App"])

Handling response

Currently there is only one method that you can call to get back the requests response and it returns NSData.

KituraRequest.request(.get, "https://google.com").response {
  request, response, data, error in
  // do something with data
}
