我在从服务器获取映像时遇到了问题，下面是我的代码导入UIKit

class ViewController: UIViewController {

@IBOutlet weak var getImageOutlet: UIImageView!

let get_Image_URL = "http://172.16.1.22/UploadImage/displayImage.php"
override func viewDidLoad() {
    super.viewDidLoad()
   self.getImage()

    // Do any additional setup after loading the view, typically from a nib.
}

func getImage(){
    let session = URLSession(configuration: URLSessionConfiguration.default)

    guard let url = URL(string: "http://172.16.1.22/UploadImage/displayImage.php") else { return }

    var request = URLRequest(url: url)
    request.httpMethod = "GET"

    session.dataTask(with: request) { (data, response, error) in

        if let error = error {
            print("Something went wrong: \(error)")
        }

        if let imageData = data {
            DispatchQueue.main.async {
                self.getImageOutlet.image = UIImage(data: imageData)
            }
        }
        }.resume()
}
}

如何使用我的图像没有显示在我的imageView中的任何其他方法从服务器获取图像，有人能帮助我解决这个问题吗？

当我用api链接执行它时，我的邮递员就是这样的。

我的新代码和桌面视图：

import UIKit

class ImageTableViewController: UIViewController, UITableViewDataSource, UITableViewDelegate{

final let myURL = URL(string: "http://172.16.1.22/UploadImage/displayImage.php")

var imageArray = [ImageData]()
@IBOutlet weak var imageTableVieqw: UITableView!
override func viewDidLoad() {
    super.viewDidLoad()
    self.imageTableVieqw.delegate = self
    self.imageTableVieqw.dataSource = self
    self.downloadImage()
//        self.imageTableVieqw.tableFooterView = UIView()
    // Do any additional setup after loading the view.
}
     func downloadImage(){
    guard let downloadURL = myURL else{ return }

    URLSession.shared.dataTask(with: downloadURL) { (data1, response, error) in
        print("Downloaded")
        guard let data = data1, error == nil, response != nil else{
            print("Something went wrong")
            return
        }
        do {
            let decoder = JSONDecoder()
            let downloadedimagedata = try decoder.decode(Images.self, from: data)
            print("ImageDATA=\(downloadedimagedata)")
//                print("image***=\(downloadedimagedata.images[1].imageV)")
            self.imageArray = downloadedimagedata.images
            DispatchQueue.main.async {
                self.imageTableVieqw.reloadData()
            }
        }
        catch{
            print("Catch wrong")
        }
    }.resume()
}
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return imageArray.count
}
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "imageCell") as! ImageTableViewCell
    if let imageURL = URL(string: imageArray[indexPath.row].company_logo)
       {
        DispatchQueue.global().async {
            let data = try? Data(contentsOf: imageURL)
            if let data  = data{
               let image = UIImage(data: data)
                DispatchQueue.main.async {
                    cell.imageCell.image = image
                }
            }
        }
        }

    return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 100
}
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

我的新API是什么样子的：

{
"logos": [
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/harshilpatel@gmail.com_company-registration.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/shriyakshah@gmail.com_company-registration.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/johndoe@gmail.com_Image_Test.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/zara.larsson@gmail.com_Image_Test.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/_user-profile.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/ijk@gmail.com_user-profile.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/def@gmail.com_user-profile.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/mno@email.com_user-profile.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/Dhdnm_user-profile.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/abc@email.com_user-profile.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/erp@email.com_user-profile.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/tuv@email.com_user-profile.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/rohansoni@gmail.com_Image_Test.jpg"
    },
    {
        "company_logo": "http://172.16.1.22/Book-My-BIM-API/Company-Registration-API/v1/companyImages/qwe@email.com_user-profile.jpg"
    }
]
}

我的模型创建代码：

import Foundation
class Images: Codable {
let images: [ImageData]
init(images: [ImageData]) {
    self.images = images
    }
}
class ImageData: Codable {
let company_logo: String

init(company_logo: String) {
    self.company_logo = company_logo
}
}

你实际上点击了一个.php file.To get图像，你必须点击一个像.jpg or .png extension这样的图像文件，你点击的url也是HTML数据的响应，但是它应该用json or xml.Keep响应，看看rest，这有助于你理解更多。
