Alamofire Accept and Content-Type JSON
提问by jlhonora
I'm trying to make a GET request with Alamofire in Swift. I need to set the following headers:
我正在尝试在 Swift 中使用 Alamofire 发出 GET 请求。我需要设置以下标题：
Content-Type: application/json
Accept: application/json
I could hack around it and do it directly specifying the headers for the request, but I want to do it with ParameterEncoding, as is suggested in the library. So far I have this:
我可以绕过它并直接指定请求的标头，但我想用 来做ParameterEncoding，正如库中所建议的那样。到目前为止，我有这个：
Alamofire.request(.GET, url, encoding: .JSON)
.validate()
.responseJSON { (req, res, json, error) in
if (error != nil) {
NSLog("Error: \(error)")
println(req)
println(res)
} else {
NSLog("Success: \(url)")
var json = JSON(json!)
}
}
Content-Typeis set, but not Accept. How can I do this properly?
Content-Type已设置，但未设置Accept。我怎样才能正确地做到这一点？

I ended up using URLRequestConvertiblehttps://github.com/Alamofire/Alamofire#urlrequestconvertible
我最终使用了URLRequestConvertiblehttps://github.com/Alamofire/Alamofire#urlrequestconvertible
enum Router: URLRequestConvertible {
static let baseUrlString = "someUrl"
case Get(url: String)
var URLRequest: NSMutableURLRequest {
let path: String = {
switch self {
case .Get(let url):
return "/\(url)"
}
}()
let URL = NSURL(string: Router.baseUrlString)!
let URLRequest = NSMutableURLRequest(URL:
URL.URLByAppendingPathComponent(path))
// set header fields
URLRequest.setValue("application/json",
forHTTPHeaderField: "Content-Type")
URLRequest.setValue("application/json",
forHTTPHeaderField: "Accept")
return URLRequest.0
}
}
And then just:
然后只是：
Alamofire.request(Router.Get(url: ""))
.validate()
.responseJSON { (req, res, json, error) in
if (error != nil) {
NSLog("Error: \(error)")
println(req)
println(res)
} else {
NSLog("Success")
var json = JSON(json!)
NSLog("\(json)")
}
}
Another way to do it is to specify it for the whole session, check @David's comment above:
另一种方法是为整个会话指定它，检查上面@David 的评论：
Alamofire.Manager.sharedInstance.session.configuration
.HTTPAdditionalHeaders?.updateValue("application/json",
forKey: "Accept")

Example directly from Alamofire github page:
直接来自 Alamofire github 页面的示例：
Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"])
.validate(statusCode: 200..<300)
.validate(contentType: ["application/json"])
.response { (_, _, _, error) in
println(error)
}
In your case add what you want:
在您的情况下，添加您想要的内容：
Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"])
.validate(statusCode: 200..<300)
.validate(contentType: ["application/json"])
.validate(Accept: ["application/json"])
.response { (_, _, _, error) in
println(error)
}

Simple way to use get method with query map and response type json
使用带有查询映射和响应类型 json 的 get 方法的简单方法
var parameters: [String:Any] = [
"id": "3"
]
var headers: HTTPHeaders = [
"Content-Type":"application/json",
"Accept": "application/json"
]
Alamofire.request(url, method: .get,
parameters: parameters,
encoding: URLEncoding.queryString,headers:headers)
.validate(statusCode: 200..<300)
.responseData { response in
switch response.result {
case .success(let value):
case .failure(let error):
}

Alamofire.request(url, method: .post, parameters:parameters, encoding: JSONEncoding.default).responseJSON { response in
...
}
it's work
这是工作

Try this:
尝试这个：
URLRequest.setValue("application/json",
forHTTPHeaderField: "Content-Type")
URLRequest.setValue("application/json",
forHTTPHeaderField: "Accept")
