我想下载pdf文件使用的链路，从一个API，但它总是下载的与大小5KB和总的文件损坏了，而且不能被打开，该链接是因为我已经试过了，我的代码:
import Foundation
import Alamofire
class DownloadOrderService {
static let shared = DownloadOrderService()
func downloadPDFOrder(orderID: Int, completion: @escaping(_ error: Error?)-> Void) {
let urlString = getJSON(strURL:"URL")
let destination: DownloadRequest.Destination = { _, _ in
let documentsURL:NSURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first! as NSURL
debugPrint("***documentURL: ",documentsURL)
let fileURL = documentsURL.appendingPathComponent("\(orderID).pdf")
debugPrint("***fileURL: ",fileURL ?? "")
return (fileURL!,[.removePreviousFile, .createIntermediateDirectories])
}
AF.download(urlString,method: .get, encoding: JSONEncoding.default, to: destination).downloadProgress(closure: { (prog) in
}).response { response in
if response.error == nil {
debugPrint(response)
completion(nil)
}
else {
completion(response.error)
}
}
}
}
所有打印的发言，我在我的代码结果和响应，以及：

更新： 我甚至已经创建的另一个功能，导致我相同的问题再次：
func savePdf(orderID: Int) {
let urlString = getJSON(strURL:"url")
DispatchQueue.main.async {
let pdfData = try? Data.init(contentsOf: urlString)
let resourceDocPath = (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)).last! as URL
let pdfNameFromUrl = "Orderatak-\(orderID).pdf"
let actualPath = resourceDocPath.appendingPathComponent(pdfNameFromUrl)
do {
try pdfData?.write(to: actualPath, options: .atomic)
}
catch {
debugPrint(error.localizedDescription)
}
}
}
