Question

我在从服务器获取图像时遇到问题，这是我的代码导入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image在我的imageView中显示的任何其他方法从服务器获取图像任何人都可以帮助我解决问题吗？

当我使用api链接执行它时，这就是我的邮递员的样子

我的新代码与tableview：

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如何：

{
"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/_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
}
}

Answer 1

实际上您点击了.php文件。要获取图片，您必须点击.jpg or .png extension等图片文件，并且您点击的url是HTML数据的响应，但它应该以{{1}}回复。请继续关注休息api。它可以帮助您了解更多信息。
