私はAlamofireを使ってSwiftのボディで投稿リクエストをしようとしています。
私のjsonの体はこんな感じです:
{
"IdQuiz" : 102,
"IdUser" : "iosclient",
"User" : "iosclient",
"List":[
{
"IdQuestion" : 5,
"IdProposition": 2,
"Time" : 32
},
{
"IdQuestion" : 4,
"IdProposition": 3,
"Time" : 9
}
]
}
NSDictionnaryでlet
list
を作成しようとしています。
[[Time: 30, IdQuestion: 6510, idProposition: 10], [Time: 30, IdQuestion: 8284, idProposition: 10]]
そしてAlamofireを使った私のリクエストはこんな感じです:
Alamofire.request(.POST, "http://myserver.com", parameters: ["IdQuiz":"102","IdUser":"iOSclient","User":"iOSClient","List":list ], encoding: .JSON)
.response { request, response, data, error in
let dataString = NSString(data: data!, encoding:NSUTF8StringEncoding)
println(dataString)
}
リクエストにエラーがあり、問題は辞書リストにあると考えています。リストなしでリクエストをした場合、問題なく動作します。
私は解決策を提案しようとしましたが、私は同じ問題に直面しています:
let json = ["List":list,"IdQuiz":"102","IdUser":"iOSclient","UserInformation":"iOSClient"]
let data = NSJSONSerialization.dataWithJSONObject(json, options: NSJSONWritingOptions.PrettyPrinted,error:nil)
let jsons = NSString(data: data!, encoding: NSUTF8StringEncoding)
Alamofire.request(.POST, "http://myserver.com", parameters: [:], encoding: .Custom({
(convertible, params) in
var mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
mutableRequest.HTTPBody = jsons!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
return (mutableRequest, nil)
}))
.response { request, response, data, error in
let dataString = NSString(data: data!, encoding:NSUTF8StringEncoding)
println(dataString)
}
あなたは近いです。パラメータ辞書のフォーマットは正しくありません。次のことを試してください。
let parameters: [String: AnyObject] = [
"IdQuiz" : 102,
"IdUser" : "iosclient",
"User" : "iosclient",
"List": [
[
"IdQuestion" : 5,
"IdProposition": 2,
"Time" : 32
],
[
"IdQuestion" : 4,
"IdProposition": 3,
"Time" : 9
]
]
]
Alamofire.request(.POST, "http://myserver.com", parameters: parameters, encoding: .JSON)
.responseJSON { request, response, JSON, error in
print(response)
print(JSON)
print(error)
}
うまくいけば、それはあなたの問題を修正しました。そうでない場合は、返信してください。それに応じて回答を調整します。
Alamofire v4.0以降を使用している場合は、承認された回答は次のようになります。
let parameters: [String: Any] = [
"IdQuiz" : 102,
"IdUser" : "iosclient",
"User" : "iosclient",
"List": [
[
"IdQuestion" : 5,
"IdProposition": 2,
"Time" : 32
],
[
"IdQuestion" : 4,
"IdProposition": 3,
"Time" : 9
]
]
]
Alamofire.request("http://myserver.com", method: .post, parameters: parameters, encoding: JSONEncoding.default)
.responseJSON { response in
print(response)
}
私はこれまでのところ(SwiftDeveloperによる one を除いて)他の答えのどれも好きではありません。 JSON自体の構造.
正しい answer は、afrodevによって別の質問に投稿されています。あなたはそれを行って投票するべきです。
いくつかの小さな変更(主に明示的なUTF-8文字セット)を除いて、以下は私の適応です。
let urlString = "https://example.org/some/api"
let json = "{\"What\":\"Ever\"}"
let url = URL(string: urlString)!
let jsonData = json.data(using: .utf8, allowLossyConversion: false)!
var request = URLRequest(url: url)
request.httpMethod = HTTPMethod.post.rawValue
request.setValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
Alamofire.request(request).responseJSON {
(response) in
print(response)
}
Xcode 8.X、Swift 3.X
簡単に使える
let params:NSMutableDictionary? = [
"IdQuiz" : 102,
"IdUser" : "iosclient",
"User" : "iosclient",
"List": [
[
"IdQuestion" : 5,
"IdProposition": 2,
"Time" : 32
],
[
"IdQuestion" : 4,
"IdProposition": 3,
"Time" : 9
]
]
];
let ulr = NSURL(string:"http://myserver.com" as String)
let request = NSMutableURLRequest(url: ulr! as URL)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let data = try! JSONSerialization.data(withJSONObject: params!, options: JSONSerialization.WritingOptions.prettyPrinted)
let json = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
if let json = json {
print(json)
}
request.httpBody = json!.data(using: String.Encoding.utf8.rawValue);
Alamofire.request(request as! URLRequestConvertible)
.responseJSON { response in
// do whatever you want here
print(response.request)
print(response.response)
print(response.data)
print(response.result)
}
私はわずかに編集しました SwiftDeveloper 答えは、私にとってはうまくいかなかったので。私はAlamofire検証も追加しました。
let body: NSMutableDictionary? = [
"name": "\(nameLabel.text!)",
"phone": "\(phoneLabel.text!))"]
let url = NSURL(string: "http://server.com" as String)
var request = URLRequest(url: url! as URL)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let data = try! JSONSerialization.data(withJSONObject: body!, options: JSONSerialization.WritingOptions.prettyPrinted)
let json = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
if let json = json {
print(json)
}
request.httpBody = json!.data(using: String.Encoding.utf8.rawValue)
let alamoRequest = Alamofire.request(request as URLRequestConvertible)
alamoRequest.validate(statusCode: 200..<300)
alamoRequest.responseString { response in
switch response.result {
case .success:
...
case .failure(let error):
...
}
}
Swift4
とAlamofire v4.0
を使用している場合、承認されたコードは次のようになります。
let parameters: Parameters = [ "username" : email.text!, "password" : password.text! ]
let urlString = "https://api.harridev.com/api/v1/login"
let url = URL.init(string: urlString)
Alamofire.request(url!, method: .put, parameters: , encoding: JSONEncoding.default, headers: nil).responseJSON { response in
switch response.result
{
case .success(let json):
let jsonData = json as! Any
print(jsonData)
case .failure(let error):
self.errorFailer(error: error)
}
}
私が通知したい変更はほとんどありません。今後はレスポンスオブジェクトからrequest、JSON、errorにアクセスできます。
let urlstring = "Add URL String here"
let parameters: [String: AnyObject] = [
"IdQuiz" : 102,
"IdUser" : "iosclient",
"User" : "iosclient",
"List": [
[
"IdQuestion" : 5,
"IdProposition": 2,
"Time" : 32
],
[
"IdQuestion" : 4,
"IdProposition": 3,
"Time" : 9
]
]
]
Alamofire.request(.POST, urlstring, parameters: parameters, encoding: .JSON).responseJSON { response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
response.result.error
}
SwiftでHttp POST requestを作成する方法は次のとおりです。これにはJsonエンコーディングおよびヘッダーを持つパラメーターが必要です。
POST、GET、PUT、DELETEなどのすべてのタイプのリクエストを含む共有インスタンスとしてAPIクライアントBKCAPIClientを作成しました。
func postRequest(url:String, params:Parameters?, headers:HTTPHeaders?, completion:@escaping (_ responseData:Result<Any>?, _ error:Error?)->Void){
Alamofire.request(url, method: .post, parameters: params, encoding: JSONEncoding.default, headers: headers).responseJSON {
response in
guard response.result.isSuccess,
(response.result.value != nil) else {
debugPrint("Error while fetching data: \(String(describing: response.result.error))")
completion(nil,response.result.error)
return
}
completion(response.result,nil)
}
}
特定のリクエストに必要なすべてのデータと、完了ブロック内の解析ロジックを含む作成済みOperationクラス。
func requestAccountOperation(completion: @escaping ( (_ result:Any?, _ error:Error?) -> Void)){
BKCApiClient.shared.postRequest(url: BKCConstants().bkcUrl, params: self.parametrs(), headers: self.headers()) { (result, error) in
if(error != nil){
//Parse and save to DB/Singletons.
}
completion(result, error)
}
}
func parametrs()->Parameters{
return ["userid”:”xnmtyrdx”,”bcode":"HDF"] as Parameters
}
func headers()->HTTPHeaders{
return ["Authorization": "Basic bXl1c2VyOm15cGFzcw",
"Content-Type": "application/json"] as HTTPHeaders
}
このデータが必要なView ControllerでAPIを呼び出す
func callToAPIOperation(){
let accOperation: AccountRequestOperation = AccountRequestOperation()
accOperation.requestAccountOperation{(result, error) in
}}
func get_Contact_list()
{
ApiUtillity.sharedInstance.showSVProgressHUD(text: "Loading..")
let cont_nunber = contact_array as NSArray
print(cont_nunber)
let token = UserDefaults.standard.string(forKey: "vAuthToken")!
let apiToken = "Bearer \(token)"
let headers = [
"Vauthtoken": apiToken,
"content-type": "application/json"
]
let myArray: [Any] = cont_nunber as! [Any]
let jsonData: Data? = try? JSONSerialization.data(withJSONObject: myArray, options: .prettyPrinted)
// var jsonString: String = nil
var jsonString = String()
if let aData = jsonData {
jsonString = String(data: aData, encoding: .utf8)!
}
let url1 = "URL"
var request = URLRequest(url: URL(string: url1)!)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = jsonData as! Data
// let session = URLSession.shared
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print("error=\(String(describing: error))")
ApiUtillity.sharedInstance.dismissSVProgressHUD()
return
}
print("response = \(String(describing: response))")
let responseString = String(data: data, encoding: .utf8)
print("responseString = \(String(describing: responseString))")
let json = self.convertStringToDictionary(text: responseString!)! as NSDictionary
print(json)
let status = json.value(forKey: "status") as! Int
if status == 200
{
let array = (json.value(forKey: "data") as! NSArray).mutableCopy() as! NSMutableArray
}
else if status == 401
{
ApiUtillity.sharedInstance.dismissSVProgressHUD()
}
else
{
ApiUtillity.sharedInstance.dismissSVProgressHUD()
}
}
task.resume()
}
func convertStringToDictionary(text: String) -> [String:AnyObject]? {
if let data = text.data(using: String.Encoding.utf8) {
do {
let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String:AnyObject]
return json
} catch {
print("Something went wrong")
}
}
return nil
}
モデルやものをどう進めるか疑問に思う方は、以下をご覧ください
var itemArr: [Dictionary<String, String>] = []
for model in models {
let object = ["param1": model.param1,
"param2": model.param2]
itemArr.append(object as! [String : String])
}
let param = ["field1": someValue,
"field2": someValue,
"field3": itemArr] as [String : Any]
let url: URLConvertible = "http://------"
Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default)
.responseJSON { response in
self.isLoading = false
switch response.result {
case .success:
break
case .failure:
break
}
}
