[英]Why can't I initialize or make a request with SessionManager in Alamofire 4.0? (UPDATED)
Migrating to Alamofire 4
and I am trying to initialize a session manager like so: 迁移到
Alamofire 4
,我正在尝试初始化会话管理器,如下所示:
let configuration = URLSessionConfiguration.default
configuration.timeoutIntervalForRequest = 20
configuration.httpAdditionalHeaders = ["MyCompany-User-Agent": Config.MyCompanyUserAgentDataString]
var alamoManager: SessionManager = Alamofire.SessionManager(configuration: configuration)
However I keep getting the error as 但是我一直收到错误
Cannot invoke SessionManager with an argument list of type(configuration: URLSessionConfiguration)
无法使用参数列表类型(配置:URLSessionConfiguration)调用SessionManager
I am following the syntax at https://github.com/Alamofire/Alamofire#modifying-the-session-configuration , but mine has errors. 我遵循https://github.com/Alamofire/Alamofire#modifying-the-session-configuration的语法,但是我的有错误。 What am I doing wrong here?
我在这里做错了什么? Also I can't do a request from the
SessionManager
. 我也不能从
SessionManager
发出请求。
For example: 例如:
Alamofire.request(url, method: .get, parameters: parameters, encoding: JSONEncoding.default).responseObject { (response: DataResponse<MyCustomResponse>) in
if let result = response.result.value {} }
Works with no issues, BUT (where alamoManager is a SessionManager): 但 没有问题, 但正常工作 (其中alamoManager是SessionManager):
alamoManager.request(url, method: .get, parameters: parameters, encoding: JSONEncoding.default).responseObject { (response: DataResponse<MyCustomResponse>) in
if let result = response.result.value {} }
It doesn't work. 没用 I get the error as
我得到的错误
Value of type SessionManager has no member request
类型为SessionManager的值没有成员请求
Very confused as to why I am getting that error. 关于我为什么收到该错误的消息非常困惑。 The docs clearly show an example of a
SessionManager
object using a request method. 该文档清楚地显示了使用请求方法的
SessionManager
对象的示例。
I have noticed though that there are no issues with this code if I create a new project. 我注意到,如果我创建一个新项目,则此代码没有任何问题。 However in my existing project these errors display.
但是,在我现有的项目中,将显示这些错误。 I have checked the
Podfile.lock
and the version of Alamofire
is indeed 4.0. 我检查了
Podfile.lock
和版本Alamofire
确实是4.0。 I have build settings to target iOS9.0 for all targets and the project. 我有针对所有目标和项目的目标iOS9.0的构建设置。
Could someone help me with this please? 有人可以帮我吗? Tearing my hair out a bit!
弄乱我的头发!
I Suggest you initialize the extra headers with Alamofire's default Headers: 我建议您使用Alamofire的默认标头初始化额外的标头:
// Adding Headers:
var defaultHeaders = Alamofire.SessionManager.defaultHTTPHeaders
defaultHeaders["MyCompany-User-Agent"] = Config.MyCompanyUserAgentDataString
// adding Configuration:
let configuration = URLSessionConfiguration.default
configuration.httpAdditionalHeaders = defaultHeaders
configuration.timeoutIntervalForRequest = 20
var alamoManager: SessionManager = Alamofire.SessionManager(configuration: configuration)
