Alamofire 接受并 Content-Type JSON
Alamofire Accept and Content-Type JSON
我正尝试在 Swift 中使用 Alamofire 发出 GET 请求。我需要设置以下 headers:
Content-Type: application/json
Accept: application/json
我可以绕过它并直接为请求指定 headers,但我想按照库中的建议使用 ParameterEncoding
来完成。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-Type
已设置,但未设置 Accept
。我怎样才能正确地做到这一点?
示例直接来自 Alamofire github 页面:
Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"])
.validate(statusCode: 200..<300)
.validate(contentType: ["application/json"])
.response { (_, _, _, error) in
println(error)
}
根据你的情况添加你想要的:
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)
}
我最终使用了 URLRequestConvertible
https://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
}
}
然后就是:
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)")
}
}
另一种方法是为整个会话指定它,查看上面@David 的评论:
Alamofire.Manager.sharedInstance.session.configuration
.HTTPAdditionalHeaders?.updateValue("application/json",
forKey: "Accept")
试试这个:
URLRequest.setValue("application/json",
forHTTPHeaderField: "Content-Type")
URLRequest.setValue("application/json",
forHTTPHeaderField: "Accept")
使用具有查询映射和响应类型的 get 方法的简单方法 json
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
...
}
工作正常
