[操作系统]iOS 开发学习之路(登陆验证调用WebService)二


    swift3.0下使用Alamofire调用Webservice遇到的一些问题以及解决方案。

    首先是针对没有证书的https下的接口处理问题(ps:不推荐在正式版本中使用),manager.request替换掉了Alamofire.request。

let manager = Alamofire.SessionManager.default    manager.delegate.sessionDidReceiveChallenge = { session, challenge in      var disposition: URLSession.AuthChallengeDisposition = .performDefaultHandling      var credential: URLCredential?            if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust {        disposition = URLSession.AuthChallengeDisposition.useCredential        credential = URLCredential(trust: challenge.protectionSpace.serverTrust!)      } else {          if challenge.previousFailureCount > 0 {            disposition = .cancelAuthenticationChallenge          } else {            credential = manager.session.configuration.urlCredentialStorage?.defaultCredential(for: challenge.protectionSpace)            if credential != nil {            disposition = .useCredential          }        }      }            return (disposition, credential)    }

    针对soap协议,使用mutableURLRequest来进行请求。

    mutableURLRequest.setValue("text/", forHTTPHeaderField: "Content-Type")    mutableURLRequest.setValue(action, forHTTPHeaderField: "SOAPAction")    mutableURLRequest.setValue(String(soapMsg.characters.count), forHTTPHeaderField: "Content-Length")    mutableURLRequest.httpMethod = "POST"    mutableURLRequest.httpBody = soapMsg.data(using: String.Encoding.utf8)

    得到返回的值包含来

    manager.request(mutableURLRequest as URLRequest).responseData{ response in      //debugPrint(response)      let )      let a: String = ("soap:Envelope"]["soap:Body"]["FindUserNewResponse"]["FindUserNewResult"].element?.text)!      print(a)      if !a.isEmpty && a != "err:账号或密码有误!"{        let data = a.data(using: String.Encoding.utf8)! as Data        let a_dic = try? JSONSerialization.jsonObject(with: data as Data, options: JSONSerialization.ReadingOptions.mutableContainers)        if let dict = a_dic as? Dictionary<String, String> {          print(dict["姓名"]!)          print(dict["地区"]!)          callback?(true)        }      }else{        callback?(false)      }    }

    注意上面使用了一个回调函数,这是因为Alamofire调用WebService是异步的方式,这里通过isOk来判定登陆是否成功。

 func reqWebService(values: Dictionary<String, String>, callback: ((_ isOk: Bool)->Void)?){}
