我使用Alamofire
实现了一个带有自定义标头的POST请求,因为我们使用OAuth2并且我们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题。
HTTP标头字段Authorization
的访问标记值对我不起作用。服务器生成错误,因为带有访问令牌的OAuth的标头信息不可用。
但我的代码中的错误是什么?
这是我目前的代码:
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)")
}

以下是我如何将其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,只要您提出请求,它就会使用指定的标头。
您的代码已重构:
记住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)
正如你所看到的,你不必在其中传递NSURL,只是URL的字符串,Alamofire负责其余部分。

有一个简单的解决方案,可以通过单个Alamofire请求为Swift 3和Alamofire 4.0发送参数和标题
let url = "myURL"
let parameters: Parameters = [
"param1": "hello",
"param2": "world"
]
let headers = [
"x-access-token": "myToken",
]
Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseJSON { (response) in
if response.result.isFailure {
//In case of failure
}else {
//in case of success
}
}

let headers: HTTPHeaders = [
"Cookie": UserDefaultsUtil.getString(param: Constants.COOKIE),
"Accept": "application/json"
]
Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers)
.responseObject { (response: DataResponse<Any>) in
if response.result.isSuccess {
}
else {
}
}

从Alamofire 5.0.0开始,您可以使用类型HTTPHeader
的集合添加自定义HTTP标头。因此,要添加自定义用户代理标头,您可以按照以下步骤操作:
urlRequest.headers.add(.userAgent("Custom User Agent Here"))
