如何在iOS Swift 4中处理Alamofire响应？

如何解决如何在iOS Swift 4中处理Alamofire响应？

我能够使用Alamofire集成POST请求。我正在获取以下回复。但我需要将“ docname”关键文档添加到数组中。您能不能请任何人指导我处理此回复

My Response:

{
    "ResponsePayload": {
        "StatusData": {
            "StatusCode": "200","Status": "SUCCESS","Documents": [
                {
                    "docname": "Standard","isuploaded": "true"
                },{
                    "docname": "Standard2",{
                    "docname": "Standard3","isuploaded": "false"
                },{
                    "docname": "Standard4",{
                    "docname": "Standard5",{
                    "docname": "Standard",{
                    "docname": "DNC Format",{
                    "docname": "Form 60","isuploaded": "false"
                }
            ]
        }
    }
}

我的源代码：

func getMandatoryDocs（）{

    print("calling ")
    
let url = "url"
    
    
    let headers = ["Content-Type": "application/json"]

    
    let parameters: Parameters = [
        "Request": [
            "RequestPayload": [
                "ProposalId": self.textField?.text!,"Type": "getMandatoryDocuments"
            ]
        ]
    ]
    
    
Alamofire.request(url,method: .post,parameters: parameters,encoding: JSONEncoding.default,headers: headers).responseJSON { (response) in
            if response.result.isFailure {
                            //In case of failure
                }else {
                            //in case of success

//打印（响应）

                            switch response.result {
                            case .success(let response):
                                //Sucess
                                //                        self.progress.hide()
                                //                            print("response :-",response)
        
                                let json = response as? [String: Any]

// print（json！）

                                self.status = json!["Status"] as? String
        
                                print(self.status)
                
                            case .failure(let error):
                                //Failure
                                print(error.localizedDescription)
                                //                        self.progress.hide()
                            }
        
        
        
        
        
                        }
                    }
    
}

解决方法

如下所示为响应json创建数据类型，然后使用JSONDecoder解析响应。

// MARK: - PostBody
struct PostBody: Codable {
    let responsePayload: ResponsePayload

    enum CodingKeys: String,CodingKey {
        case responsePayload = "ResponsePayload"
    }
}

// MARK: - ResponsePayload
struct ResponsePayload: Codable {
    let statusData: StatusData

    enum CodingKeys: String,CodingKey {
        case statusData = "StatusData"
    }
}

// MARK: - StatusData
struct StatusData: Codable {
    let statusCode: String
    let status: String
    let documents: [Document]

    enum CodingKeys: String,CodingKey {
        case statusCode = "StatusCode"
        case status = "Status"
        case documents = "Documents"
    }
}

// MARK: - Document
struct Document: Codable {
    let docname: String
    let isUploaded: String

    enum CodingKeys: String,CodingKey {
        case docname = "docname"
        case isUploaded = "isUploaded"
    }
}

AF.request(url,method: .post,parameters: parameters,encoding: JSONEncoding.default,headers: headers).responseData { response in
    switch response.result {
    case .success(let data):
        do {
            let postBody = try JSONDecoder().decode(PostBody.self,from: data)
            print(postBody.responsePayload.statusData.statusCode)
            print(postBody.responsePayload.statusData.documents.map { $0.docname })
         } catch {
             print(error)
         }
    case .failure(let error):
        print(error)
    }
}
