我Alamofire使用自定义标头实现了POST请求,因为我们使用OAuth2,并且必须在标头内的每个请求中发送访问令牌。在这种情况下,我必须使用自定义标头。
Alamofire
HTTP标头字段的访问令牌值Authorization对我不起作用。服务器生成错误,因为带有访问令牌的OAuth标头信息不可用。
Authorization
但是我的代码有什么错误呢?
这是我当前的代码:
let URL = NSURL(string: url + "/server/rest/action") var mutableURLRequest = NSMutableURLRequest(URL: URL!) mutableURLRequest.setValue("Bearer \(accessToken)", forHTTPHeaderField: "Authorization") //this method does not work anymore because it returns an error in the response //Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders = ["Authorization": "Bearer \(accessToken)"] Alamofire.Manager.sharedInstance .request(.POST, mutableURLRequest, parameters: parameters, encoding: .JSON) .validate() .responseJSON { (request, response, data, error) -> Void in NSLog("REQUEST: \(request)") NSLog("RESPONSE: \(response)") NSLog("DATA: \(data)") NSLog("ERROR: \(error)") }
这是我如何与自定义标头一起使用的示例:
var manager = Manager.sharedInstance // Specifying the Headers we need manager.session.configuration.HTTPAdditionalHeaders = [ "Content-Type": "application/x-www-form-urlencoded", "Accept": "application/vnd.lichess.v1+json", "X-Requested-With": "XMLHttpRequest", "User-Agent": "iMchess" ]
现在,无论何时发出请求,它都会使用指定的标头。
您的代码已重构:请记住 import Alamofire
import Alamofire
let aManager = Manager.sharedInstance manager.session.configuration.HTTPAdditionalHeaders = [ "Authorization": "Bearer \(accessToken)" ] let URL = url + "/server/rest/action" request(.POST, URL, encoding: .JSON) .responseJSON { (request, response, data, error) -> Void in println("REQUEST: \(request)") println("RESPONSE: \(response)") println("DATA: \(data)") println("ERROR: \(error)") }
这是请求签名 request(method: Method, URLString: URLStringConvertible>, parameters: [String : AnyObject]?, encoding: ParameterEncoding)
request(method: Method, URLString: URLStringConvertible>, parameters: [String : AnyObject]?, encoding: ParameterEncoding)
如您所见,您不必在其中传递NSURL,只需传递URL的字符串即可,其余的则由Alamofire负责。
