我编写了以下代码，我在JSON中也得到了响应，但JSON的类型是“AnyObject”，我无法将其转换为Array，以便我可以使用它。
Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON
{
(request, response, JSON, error) in
println(JSON?)
}

Swift 2.0 Alamofire 3.0的答案应该看起来更像是这样：
Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON).responseJSON
{ response in switch response.result {
case .Success(let JSON):
print("Success with JSON: \(JSON)")
let response = JSON as! NSDictionary
//example if there is an id
let userId = response.objectForKey("id")!
case .Failure(let error):
print("Request failed with error: \(error)")
}
}
Alamofire 4.0和Swift 3.0的更新：
Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)
.responseJSON { response in
print(response)
//to get status code
if let status = response.response?.statusCode {
switch(status){
case 201:
print("example success")
default:
print("error with response status: \(status)")
}
}
//to get JSON return value
if let result = response.result.value {
let JSON = result as! NSDictionary
print(JSON)
}
}

如上所述，您可以使用SwiftyJSON库并获取您的值，就像我在下面所做的那样
Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON
{
(request, response, data, error) in
var json = JSON(data: data!)
println(json)
println(json["productList"][1])
}
我的json产品列表从脚本返回
{ "productList" :[
{"productName" : "PIZZA","id" : "1","productRate" : "120.00","productDescription" : "PIZZA AT 120Rs","productImage" : "uploads\/pizza.jpeg"},
{"productName" : "BURGER","id" : "2","productRate" : "100.00","productDescription" : "BURGER AT Rs 100","productImage" : "uploads/Burgers.jpg"}
]
}
输出：
{
"productName" : "BURGER",
"id" : "2",
"productRate" : "100.00",
"productDescription" : "BURGER AT Rs 100",
"productImage" : "uploads/Burgers.jpg"
}

Alamofire.request(.GET, URLString, parameters: ["foo": "bar"])
.responseJSON { request, response, result in
switch result {
case .Success(let JSON):
print("Success with JSON: \(JSON)")
case .Failure(let data, let error):
print("Request failed with error: \(error)")
if let data = data {
print("Response data: \(NSString(data: data, encoding: NSUTF8StringEncoding)!)")

Swift 3，Alamofire 4.4和SwiftyJSON：
Alamofire.request(url, method: .get)
.responseJSON { response in
if response.data != nil {
let json = JSON(data: response.data!)
let name = json["people"][0]["name"].string
if name != nil {
print(name!)
}
}
}
这将解析此JSON输入：
{
people: [
{ name: 'John' },
{ name: 'Dave' }
]
}

我既不是JSON专家，也不是Swift专家，但以下内容对我有用。 :)我从我当前的应用程序中提取了代码，并且只更改了“MyLog to println”，并使用空格缩进以使其显示为代码块（希望我没有破坏它）。
func getServerCourseVersion(){
Alamofire.request(.GET,"\(PUBLIC_URL)/vtcver.php")
.responseJSON { (_,_, JSON, _) in
if let jsonResult = JSON as? Array<Dictionary<String,String>> {
let courseName = jsonResult[0]["courseName"]
let courseVersion = jsonResult[0]["courseVersion"]
let courseZipFile = jsonResult[0]["courseZipFile"]
println("JSON: courseName: \(courseName)")
println("JSON: courseVersion: \(courseVersion)")
println("JSON: courseZipFile: \(courseZipFile)")
}
}
}
希望这有帮助。
编辑：
供参考，这是我的PHP脚本返回的内容：
[{"courseName": "Training Title","courseVersion": "1.01","courseZipFile": "101/files.zip"}]

我通常使用Gloss库在iOS中序列化或反序列化JSON。例如，我的JSON看起来像这样：
{"ABDC":[{"AB":"qwerty","CD":"uiop"}],[{"AB":"12334","CD":"asdf"}]}
首先，我在Gloss struct中编写JSON数组：
Struct Struct_Name: Decodable {
let IJ: String?
let KL: String?
init?(json: JSON){
self.IJ = "AB" <~~ json
self.KL = "CD" <~~ json
}
}
然后在Alamofire responseJSON中，我执行以下操作：
Alamofire.request(url, method: .get, paramters: parametersURL).validate(contentType: ["application/json"]).responseJSON{ response in
switch response.result{
case .success (let data):
guard let value = data as? JSON,
let eventsArrayJSON = value["ABDC"] as? [JSON]
else { fatalError() }
let struct_name = [Struct_Name].from(jsonArray: eventsArrayJSON)//the JSON deserialization is done here, after this line you can do anything with your JSON
for i in 0 ..< Int((struct_name?.count)!) {
print((struct_name?[i].IJ!)!)
print((struct_name?[i].KL!)!)
}
break
case .failure(let error):
print("Error: \(error)")
break
}
}
上述代码的输出：
qwerty
uiop
1234
asdf

我找到了一种方法将response.result.value（在Alamofire responseJSON闭包内）转换为我在我的应用中使用的JSON格式。
我正在使用Alamofire 3和Swift 2.2。
这是我使用的代码：
Alamofire.request(.POST, requestString,
parameters: parameters,
encoding: .JSON,
headers: headers).validate(statusCode: 200..<303)
.validate(contentType: ["application/json"])
.responseJSON { (response) in
NSLog("response = \(response)")
switch response.result {
case .Success:
guard let resultValue = response.result.value else {
NSLog("Result value in response is nil")
completionHandler(response: nil)
return
}
let responseJSON = JSON(resultValue)
// I do any processing this function needs to do with the JSON here
// Here I call a completionHandler I wrote for the success case
break
case .Failure(let error):
NSLog("Error result: \(error)")
// Here I call a completionHandler I wrote for the failure case
return
}

这是使用Xcode 10.1和Swift 4构建的
完美的组合“ Alamofire”（4.8.1）和“ SwiftyJSON”（4.2.0）。首先，您应该同时安装两个Pod
pod 'Alamofire'和pod 'SwiftyJSON'
JSON格式的服务器响应：
{
"args": {},
"headers": {
"Accept": "*/*",
"Accept-Encoding": "gzip;q=1.0, compress;q=0.5",
"Accept-Language": "en;q=1.0",
"Host": "httpbin.org",
"User-Agent": "AlamoFire TEST/1.0 (com.ighost.AlamoFire-TEST; build:1; iOS 12.1.0) Alamofire/4.8.1"
},
"origin": "200.55.140.181, 200.55.140.181",
"url": "https://httpbin.org/get"
}
在这种情况下，我要打印“主机”信息：“主机”：“ httpbin.org”
Alamofire.request("https://httpbin.org/get").validate().responseJSON { response in
switch response.result {
case .success:
print("Validation Successful)")
if let json = response.data {
do{
let data = try JSON(data: json)
let str = data["headers"]["Host"]
print("DATA PARSED: \(str)")
}
catch{
print("JSON Error")
}
}
case .failure(let error):
print(error)
}
}

在Swift 5中，我们喜欢使用typealias作为补全。 Typlealias只是清理代码而已。
typealias response = (Bool,Any?)->()
static func postCall(_ url : String, param : [String : Any],completion : @escaping response){
Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default, headers: [:]).responseJSON { (response) in
switch response.result {
case .success(let JSON):
print("\n\n Success value and JSON: \(JSON)")
case .failure(let error):
print("\n\n Request failed with error: \(error)")
}
}
}

简单的答案是让 AlamoFire 直接进行解码。
令人惊讶的是，您没有使用 .responseJSON，因为它返回一个无类型的 json 对象
相反，您使对象可解码 - 并要求 AF 直接解码它们
我的 json 响应包含一组 Account 对象。我只关心 id 和 name 键（虽然还有更多）
struct Account:Codable {
let id:Int
let name:String
}
然后简单
AF.request(url,
method: .get)
.responseDecodable(of:[Account].self) { response in
switch response.result {
case .success:
switch response.response?.statusCode {
case 200:
//response.value is of type [Account]
default:
//handle other cases
}
case let .failure(error):
//probably the decoding failed because your json doesn't match the expected format
}
}
