ios - 如何使用 swift 发出 HTTP Post 请求

Question

typealias ServiceResponse = (JSON, NSError?) -> Void
class RestApiManager: NSObject {
    static let sharedInstance = RestApiManager()
    let baseURL = "http://api.randomuser.me/"
    func postUser(){}
    func getRandomUser(onCompletion: (JSON) -> Void) {
        let route = baseURL
        makeHTTPGetRequest(route, onCompletion: { json, err in
            onCompletion(json as JSON)
        })
    }
    func makeHTTPGetRequest(path: String, onCompletion: ServiceResponse) {
        let request = NSMutableURLRequest(URL: NSURL(string: path)!)
        let session = NSURLSession.sharedSession()
        let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
            let json:JSON = JSON(data: data)
            onCompletion(json, error)
        })
        task.resume()
    }
    func makeHTTPPostRequest(path: String, body: [String: AnyObject], onCompletion: ServiceResponse) {
        var err: NSError?
        let request = NSMutableURLRequest(URL: NSURL(string: path)!)
        // Set the method to POST
        request.HTTPMethod = "POST"
        // Set the POST body for the request
        request.HTTPBody = NSJSONSerialization.dataWithJSONObject(body, options: nil, error: &err)
        let session = NSURLSession.sharedSession()
        let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
            let json:JSON = JSON(data: data)
            onCompletion(json, err)
        })
        task.resume()
    }
}

如何在 ViewController 中调用 httppost 方法 postuser 并将 header + 编码参数传递给它？

喜欢 http://www.api.com/post/data?username=kr%209&password=12我还需要在 ehader 中发送 session /cookie/useragent。

Answer 1

request.setValue("Your Header value", forHTTPHeaderField: "Header-Key") //User-Agent for ex.
