網絡層的福爾摩斯：ResponseDetective

ResponseDetective 是一個非侵入式框架用于攔截任何傳出請求和輸入響應在你的App和你的服務器之間，以達到調試的目的。 

Usage

Incorporating ResponseDetective in your project is very simple – it all comes down to a couple of steps.

Step 1: Register interceptors

You may register as many request, response and error interceptors as you like.

// request
InterceptingProtocol.registerRequestInterceptor(BaseInterceptor())
InterceptingProtocol.registerRequestInterceptor(JSONInterceptor())

// response
InterceptingProtocol.registerResponseInterceptor(BaseInterceptor())
InterceptingProtocol.registerResponseInterceptor(JSONInterceptor())
InterceptingProtocol.registerResponseInterceptor(HTMLInterceptor())

// error
InterceptingProtocol.registerErrorInterceptor(BaseInterceptor())

Step 2: Register the protocol

ForInterceptingProtocolto work, it needs to be added as a middleman between yourNSURLSessionand the Internet. You can do this by registering it in your session'sNSURLSessionConfiguration.protocolClasses.

let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
configuration.protocolClasses = [InterceptingProtocol.self]

let session = NSURLSession(configuration: configuration)

If you're using Alamofire as your networking framework, integrating ResponseDetective is as easy as initializing yourManagerwithNSURLSessionConfigurationdescribed above.

let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
configuration.protocolClasses = [InterceptingProtocol.self]

let manager = Alamofire.Manager(configuration: configuration)

Step 3: Profit

Now it's time to perform the actual request.

let request = NSURLRequest(URL: NSURL(string: "http://httpbin.org/get")!)
let task = session.dataTaskWithRequest(request)
task.resume()

Voilà! Now check out your console output.
