上传图像失败 我邮寄图像到PHP

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate { 

@IBOutlet var image: UIImageView! 

override func viewDidLoad() { 
    super.viewDidLoad() 
} 

@IBAction func selectPicture(_ sender: AnyObject) { 

    let ImagePicker = UIImagePickerController() 
    ImagePicker.delegate = self 
    ImagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary 

    self.present(ImagePicker, animated: true, completion: nil)  
} 

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { 

    image.image = info[UIImagePickerControllerOriginalImage] as? UIImage 
    self.dismiss(animated: true, completion: nil) 
} 

@IBAction func upload_request(_ sender: AnyObject) { 
    UploadRequest() 
} 

func UploadRequest()

    let url = URL(string: "http://127.0.0.1/imgJSON/img.php") 

    let request = NSMutableURLRequest(url: url!) 
    request.httpMethod = "POST" 

    let boundary = generateBoundaryString()   

    request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type") 

    if (image.image == nil) 
    { 
     return 
    } 

    let image_data = UIImagePNGRepresentation(image.image!) 

    if(image_data == nil) 
    { 
     return

    let body = NSMutableData() 

    let fname = "test.png" 
    let mimetype = "image/png" 

    body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!) 
    body.append("Content-Disposition:form-data; name=\"test\"\r\n\r\n".data(using: String.Encoding.utf8)!)

    body.append("\r\n".data(using: String.Encoding.utf8)!) 

    body.append("--\(boundary)--\r\n".data(using: String.Encoding.utf8)!) 

    request.httpBody = body as Data   
    let session = URLSession.shared 

    let task = URLSession.shared.dataTask(with: request as URLRequest) {   (
     data, response, error) in 

     guard let _:Data = data, let _:URLResponse = response , error == nil else { 
      print("error") 
      return 
     } 

     let dataString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue) 

     print(dataString)    
    } 
    task.resume()  
}  

func generateBoundaryString() -> String 
{ 
    return "Boundary-\(UUID().uuidString)" 
} 

在PHP

if (move_uploaded_file($_FILES['file']['tmp_name'], "image.png")) { 
echo "File uploaded: ".$_FILES["file"]["name"]; } 

Answer 1

你的第二个屏幕截图显示问题： 这是带有PHP警告的服务器回复，apache/php用户没有权限将上传的图像移动到targetdirectory中，这将成为根目录（/） - 因为您没有指定目录/路径在哪里存储图像。请参阅PHP文档的Example 1。

所以，你应该建立一个上传目录（如MKDIR /Appli.../htdocs/uploads，设置正确的权限（用于开发目的搭配chmod -R 777个上传），并在你的PHP目标目录指定：

if (move_uploaded_file($_FILES['file']['tmp_name'], "/Appli.../htdocs/uploads/image.png")) { ...
