print("swiftyJsonVar",swiftyJsonVar)
let message = swiftyJsonVar["message"].rawString()
let sudent = swiftyJsonVar["student"].rawString()!
let jsonData = sudent.data(using: .utf8)!
let dictionary = try? JSONSerialization.jsonObject(with: jsonData, options: []) as! Dictionary<String, Any>
self.name_lbl.text = dictionary?["name"] as? String
self.fatherName_lbl.text = dictionary?["father_name"] as? String
self.motherName_lbl.text = dictionary?["mother_name"] as? String
self.phone_lbl.text = dictionary?["phone"] as? String
self.email_lbl.text = dictionary?["email"] as? String
self.dob_lbl.text=dictionary?["dob"] as? String

Have a look at below code you just need to pass a link url to alamofire and you can download a image . 看下面的代码,您只需要将链接URL传递给alamofire,就可以下载图像。 if its not the expected answer please Re edit your question .
如果不是预期的答案,请重新编辑您的问题。
let strURL1:String = "https://www.planwallpaper.com/static/images/9-credit-1.jpg"
Alamofire.request(strURL1).responseData(completionHandler: { response in
debugPrint(response)
debugPrint(response.result)
if let image1 = response.result.value {
let image = UIImage(data: image1)
self.imageView.image = image
}
})
I looked at output you had provided you are getting 我查看了您提供的输出
image =
"/system/images/86/j1f9DiJi_medium.jpg?1504593436";
is this a valid url or path if its a url you need to add your base url + your " /system/images/86/j1f9DiJi_medium.jpg?1504593436"
and pass it to alamofire block to download image as in my above example 这是一个有效的网址或路径吗(如果它是一个网址),您需要添加
base url + your " /system/images/86/j1f9DiJi_medium.jpg?1504593436"
并将其传递给alamofire块以下载图片,如上面的示例所示
"https://www.planwallpaper.com" - baseURl
"static/images/9-credit-1.jpg" - image Path as in your case
Hope it helps. 希望能帮助到你。
First get the image key corresponding value & marge it with your base URL. 首先获取图像键对应的值,并将其与您的基本URL匹配。 Like
喜欢
let url = "www.yourbaseurlhere.com" + "/system/images/86/j1f9DiJi_medium.jpg?1504593436"
Now create a destination path for it like 现在为它创建一个目标路径
let destination = DownloadRequest.suggestedDownloadDestination(
for: .documentDirectory,
in: .userDomainMask
)
Now use Alamofire download method like 现在使用Alamofire下载方法,例如
Alamofire.download(url, to: destination)
.downloadProgress { progress in
print("Download Progress: \(progress.fractionCompleted)")
}
.responseData { response in
if response.result.value != nil {
if let directoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] as? URL {
let fileName = response.response?.suggestedFilename // get your file name here.
let finalPath = directoryURL.appendingPathComponent(fileName!) //get your file path here
}
}
}
Hope it helps. 希望能帮助到你。
