Tiny Networking in Swift

Transcript

1. Tiny Networking @chriseidhof
2. $ pod install AlamoFire
3. Live coding!
4. $ rake routes | grep sign_in ... api_user_session POST /api/users/sign_in(.:format)
5. $ curl "http://localhost:3000/api/users/sign_in" \ -d "{\"email\": \"chris@eidhof.nl\", \"password\": \"testtes\"}" \ --header "Content-Type:application/json" \ {"message":"Error with your login or password"}~
6. $ curl "http://localhost:3000/api/users/sign_in" -d "{\"email\": \"chris@eidhof.nl\", \"password\": \"testtest\"}" --header "Content-Type:application/json" {"auth_token":"8yBZFpqhagTJr6DpDSyS","email":"chris@eidhof.nl"}
7. func apiRequest<A>( baseURL: NSURL, resource: Resource<A>, failure: () -> (), completion: A -> () )
8. struct Resource<A> { let path: String let method : Method let headers : [String:String] let requestBody: NSData? let parse: NSData -> A? }
9. typealias JSONDictionary = [String:AnyObject] func decodeJSON(data: NSData) -> JSONDictionary? func encodeJSON(dictionary: JSONDictionary) -> NSData?
10. Usage
11. let parse : NSData -> String? = { data in if let jsonDict = decodeJSON(data) { return jsonDict["auth_token"] as? String } return nil }
12. let requestParameters = ["email": "chris@eidhof.nl", "password": "testtest"] let jsonBody = encodeJSON(requestParameters)
13. let path = "api/users/sign_in" let headers = ["Content-Type": "application/json", "Accept": "application/json"] let resource = Resource(path: path, method: .POST, requestBody: jsonBody, headers: headers, parse: parse)
14. let baseURL = NSURL(string:"http://localhost:3000")! apiRequest(baseURL, resource, { println("failure") }, { authorizationToken in println("Auth token \(authorizationToken)") })
15. let email = "chris@eidhof.nl" let password = "testtest" let baseURL = NSURL(string:"http://localhost:3000")! let resource = login(email, password) apiRequest(baseURL, resource, { println("failure") }, { authorizationToken in println("Auth token \(authorizationToken)") })
16. More live coding!
