如何在swift

Question

我正在尝试使用Alamofire在swift中发布一个帖子请求。

我的json身体看起来像：

{
    "IdQuiz" : 102,
    "IdUser" : "iosclient",
    "User" : "iosclient",
    "List":[
        {
        "IdQuestion" : 5,
        "IdProposition": 2,
        "Time" : 32
        },
        {
        "IdQuestion" : 4,
        "IdProposition": 3,
        "Time" : 9
        }
    ]
}

我正在尝试使用NSDictionnary制作let list，如下所示：

[[Time: 30, IdQuestion: 6510, idProposition: 10], [Time: 30, IdQuestion: 8284, idProposition: 10]]

我使用Alamofire的请求如下：

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)
        }

请求有错误，我认为问题出在Dictionary列表中，因为如果我在没有列表的情况下发出请求就可以正常工作了，那么任何想法？

我尝试过建议的解决方案，但我遇到了同样的问题：

 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)
    }

Answer 1

如果您使用的是Alamofire v4.0 +，那么接受的答案将如下所示：

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)
    }

Answer 2

你很亲密。参数字典格式看起来不正确。您应该尝试以下方法：

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)
    }

希望能解决您的问题。如果没有，请回复，我会相应地调整我的答案。

Answer 3

到目前为止，我不喜欢任何其他答案（除了SwiftDeveloper的one之外），因为它们要么你要反序列化你的JSON，只是为了再次序列化，或者关心它JSON本身的结构。

afrodev在另一个问题中发布了正确的answer。你应该去投票吧。

以下是我的改编，稍作修改（主要是明确的UTF-8字符集）。

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)
}

Answer 4

Xcode 8.X，Swift 3.X

易于使用;

    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)

            }

Answer 5

我略微编辑了SwiftDeveloper的答案，因为它对我不起作用。我也添加了Alamofire验证。

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):
            ...
    }
}

Answer 6

我想通知的变化很少。从现在开始，您可以从响应对象访问请求，JSON和错误。

        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
        }

Answer 7

如果您使用swift4和Alamofire v4.0，则接受的代码如下所示：

            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)
                }
            }

Answer 8

以下是我使用swift创建Http POST请求的方法，该请求需要带有Json编码和标题的参数。

创建的API客户端 BKCAPIClient作为共享实例，包括所有类型的请求，如POST，GET，PUT，DELETE等。

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)
    }
}

创建的Operation类，包含特定请求所需的所有数据，还包含完成块内的解析逻辑。

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
}

调用API在我们需要此数据的任何视图控制器中

func callToAPIOperation(){
let accOperation: AccountRequestOperation = AccountRequestOperation()
accOperation.requestAccountOperation{(result, error) in

}}

Answer 9

如果有人想知道如何继续使用模型和东西，请参见下文

        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
                }
        }

Alamofire使用POST，参数和标题获取数据

func feedbackApi(){
    DispatchQueue.main.async {
        let headers = [
            "Content-Type": "application/x-www-form-urlencoded",
            "Authorization": "------"
        ]
        let url = URL(string: "---------")
        var parameters = [String:AnyObject]()
        parameters =  [
            "device_id":"-----" as AnyObject,
            "user_id":"----" as AnyObject,
            "cinema_id":"-----" as AnyObject,
            "session_id":"-----" as AnyObject,
        ]
       Alamofire.request(url!, method: .post, parameters: parameters,headers:headers).responseJSON { response in
                switch response.result{
                case.success(let data):
                    self.myResponse = JSON(data)
                    print(self.myResponse as Any)
                    let slide = self.myResponse!["sliders"]
                    print(slide)
                    print(slide.count)
                    for i in 0..<slide.count{
                        let single = Sliders(sliderJson: slide[i])
                        self.slidersArray.append(single)
                    }
                    DispatchQueue.main.async {
                        self.getSliderCollection.reloadData()
                    }
                case .failure(let error):
                    print("dddd",error)
                }

        }
    }
