如何使用Alamofire从数组中获取数据并在CollectionCell中显示？
如何使用Alamofire从数组中获取数据并在CollectionCell中显示？
提问于 2019-06-04 07:48:11
我正在创建一个需要从API拉取数据的应用程序，场景是，我将获取以下json数据：
[
{
"chargeId": "33fbbbd0-2e33-11e9-a2cb-8a27ecbbcb73",
"chargeDate": "2019-02-12T03:28:44.000",
"vatRate": "NON-VAT",
"taxRate": 0.1,
"policyGroup": "Patient Participation",
"itemDescription": "Ecg at er/icu df",
"scdFlag": 0,
"amounts": null,
"scdDiscounts": 0,
"othDiscounts": 4.54,
"adjustment": 0,
"pfBill": 222.46,
"vatAmount": 0,
"taxableAmount": 11.12,
"merchantDiscount": 0,
"creditedAmount": 211.3,
"chargeAmount": null,
"previousCredits": null
},
{
"chargeId": "5a2cabc1-46c9-11e9-a2cf-863c7cdffd18",
"chargeDate": "2019-03-15T10:24:21.000",
"vatRate": "NON-VAT",
"taxRate": 0.1,
"policyGroup": "Patient Participation",
"itemDescription": "Professional Fees",
"scdFlag": 0,
"amounts": null,
"scdDiscounts": 0,
"othDiscounts": 0,
"adjustment": 0,
"pfBill": 1000,
"vatAmount": 0,
"taxableAmount": 100,
"merchantDiscount": 0,
"creditedAmount": 900,
"chargeAmount": null,
"previousCredits": null
}
]我使用下面的Alamofire代码成功拉取了数据：
typealias getPatientDetailsPerPayoutTaskCompletion = (_ patientDetailsPerPayout: [PatientPayoutDetails]?, _ error: NetworkError?) -> Void
static func getPatientDetailsPerPayout(periodId: Int, doctorNumber: String, parameterName: PatientParameter, hospitalNumber: String, completion: @escaping getPatientDetailsPerPayoutTaskCompletion) {
guard let patientDetailsPerPayoutURL = URL(string: "\(Endpoint.Patient.patientPayoutDetails)?periodId=\(periodId)&doctorNumber=\(doctorNumber)\(parameterName.rawValue)\(hospitalNumber)") else {
completion(nil, .invalidURL)
return
}
let sessionManager = Alamofire.SessionManager.default
sessionManager.session.getAllTasks { (tasks) in
tasks.forEach({ $0.cancel() })
}
Alamofire.request(patientDetailsPerPayoutURL, method: .get, encoding: JSONEncoding.default).responseJSON { (response) in
print(patientDetailsPerPayoutURL)
guard HelperMethods.reachability(responseResult: response.result) else {
completion(nil, .noNetwork)
return
}
guard let statusCode = response.response?.statusCode else {
completion(nil, .noStatusCode)
return
}
switch(statusCode) {
case 200:
guard let jsonData = response.data else {
completion(nil, .invalidJSON)
return
}
let decoder = JSONDecoder()
do {
let patientDetailsPayout = try decoder.decode([PatientPayoutDetails].self, from: jsonData)
completion(patientDetailsPayout, nil)
} catch {
completion(nil, .invalidJSON)
}
case 400: completion(nil, .badRequest)
case 404: completion(nil, .noRecordFound)
default:
print("**UNCAPTURED STATUS CODE FROM (getPatientDetailsPayout)\nSTATUS CODE: \(statusCode)")
completion(nil, .uncapturedStatusCode)
}
}JSON Data将显示在CollectionCell中，用户将点击cell查看一个chargedId下的数据，但不幸的是，当我点击cell时，将提取所有数据，而不是仅提取阵列的一部分。下面的代码是我用来拉取部分数组的代码：
typealias getSelectedPatientItemDetailsTaskCompletion = (_ selectedpatient: PatientPaymentDetails?, _ error: NetworkError?) -> Void
static func getPatientItemDetails(periodId: Int, doctorNumber: String, parameterName: PatientParameter, hospitalNumber: String, chargeId: String, completion: @escaping getSelectedPatientItemDetailsTaskCompletion) {
guard let patientDetailsPerPayoutURL = URL(string: "\(Endpoint.Patient.patientPayoutDetails)?periodId=\(periodId)&doctorNumber=\(doctorNumber)\(parameterName.rawValue)\(hospitalNumber)") else {
completion(nil, .invalidURL)
return
}
let sessionManager = Alamofire.SessionManager.default
sessionManager.session.getAllTasks { (tasks) in
tasks.forEach({ $0.cancel() })
}
Alamofire.request(patientDetailsPerPayoutURL, method: .get, encoding: JSONEncoding.default).responseJSON { (response) in
print(patientDetailsPerPayoutURL)
guard HelperMethods.reachability(responseResult: response.result) else {
completion(nil, .noNetwork)
return
}
guard let statusCode = response.response?.statusCode else {
completion(nil, .noStatusCode)
return
}
switch(statusCode) {
case 200:
guard let jsonData = response.data else {
completion(nil, .invalidJSON)
return
}
let decoder = JSONDecoder()
do {
let patientDetailsPayout = try decoder.decode(PatientPaymentDetails.self, from: jsonData)
completion(patientDetailsPayout, nil)
} catch {
completion(nil, .invalidJSON)
}
case 400: completion(nil, .badRequest)
case 404: completion(nil, .noRecordFound)
default:
print("**UNCAPTURED STATUS CODE FROM (getPatientDetailsPayout)\nSTATUS CODE: \(statusCode)")
completion(nil, .uncapturedStatusCode)
}
}
}
}
}用于拉取数据的Didselect函数
switch indexPath.section {
case 0:
self.selectedCardIndex = indexPath
let selectedItem = selectedItemDescription.id
getItemDetails(parameter: .searchByChargedId, from: selectedItem)
let cardController = UserCardViewController.init(nibName: "UserCardViewController", bundle: nil)
present(cardController, animated: true, completion: nil)
default: break
}
}getItemDetails函数
func getItemDetails(parameter: PatientParameter, from: String) {
APIService.PatientList.getPatientItemDetails(periodId: currentRemittance.periodId, doctorNumber: doctorNumber, parameterName: parameter, hospitalNumber: patient.hospitalNumber!, chargeId: from) { (getItem, error) in
guard let pageItemDescription = getItem, error == nil else {
SVProgressHUD.dismiss()
return
}
switch parameter {
case .selectedByChargedID:
if self.patientPayoutDetails == nil {
self.selectedPatientItemDescription = pageItemDescription
}else {
self.patientPayoutDetails.append(contentsOf: pageItemDescription.chargedId)
}
default: break
}
SVProgressHUD.dismiss()
}
} 希望你能帮助我，很抱歉，如果我几乎包括了所有的代码，但我只是想向你展示我的代码流程。我已经花了将近一周的时间来研究它。谢谢。

您的两个函数getPatientItemDetails和getPatientDetailsPerPayout都从同一个URL中检索数据：
guard let patientDetailsPerPayoutURL = URL(string: "\(Endpoint.Patient.patientPayoutDetails)?periodId=\(periodId)&doctorNumber=\(doctorNumber)\(parameterName.rawValue)\(hospitalNumber)") else {对于不同的端点，您可能有不同的URL；请验证这两种方法的URL，确保使用适当的URL。
