如何将Alamofire与自定义标头一起使用 [英] how to use Alamofire with custom headers

问题描述

我只是开始看一下Mattt出色的新型Alamofire快速联网库，还不确定如何将其与自定义标头一起使用。

I am just starting to take a look at Mattt's wonderful new Alamofire swift networking library and am not quite sure how one would use it with custom headers.

我要从AFNetworking转换为Alamofire的代码是：

The code i am trying to convert from AFNetworking to Alamofire is this:

let request = NSMutableURLRequest(URL: url)
request.setValue(authorizationToken, forHTTPHeaderField:"Authorization")

推荐答案

根据官方文档，不建议修改会话配置：

According to the official documentation, modifying the session configuration is not recommended:

不建议将其用于Authorization或Content-Type标头。
分别使用URLRequestConvertible和ParameterEncoding，
。

This is not recommended for Authorization or Content-Type headers. Instead, use URLRequestConvertible and ParameterEncoding, respectively.

因此使用URLRequestConvertible进行授权的示例是：

So an example usage of URLRequestConvertible for authorization would be:

enum Router: URLRequestConvertible {
    static let baseUrlString = "some url string"

    case Get(query: String)

    var URLRequest: NSMutableURLRequest {
        let (path: String, parameters: [String: AnyObject]?) = {
            switch self {
            case .Get(let query):
                return ("/get", ["q": query])
            }
        }()

        let URL = NSURL(string: Router.baseUrlString)!
        let URLRequest = NSMutableURLRequest(URL: URL.URLByAppendingPathComponent(path))
        // set header fields
        URLRequest.setValue("a", forHTTPHeaderField: "Authorization")

        let encoding = Alamofire.ParameterEncoding.URL        
        return encoding.encode(URLRequest, parameters: parameters).0
    }
}

，当您要提出请求时：

Manager.sharedInstance.request(Router.Get(query: "test"))

从Alamofire v1.0开始，Pers答案不再有效。在新版本中，应将其他标头添加到 NSURLSessionConfiguration

As of Alamofire v1.0 Pers answer no longer works. In the new version additional headers should be added to the HTTPAdditionalHeaders property of NSURLSessionConfiguration

Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders = ["Authorization": authorizationToken]
