Hochladen von mehreren Bildern mit anderen Parametern in Swift

Question

Im Moment habe ich nur ein Bild auf einen Server auf einem Server-Side-Skript hochgeladen durch den unten angegebenen Code. Jetzt habe ich ein Array von UIImage, ich möchte wissen, wie kann ich UIImageJPEGRepresentation(myImageView.image!, 0.1) verwenden, um alle Bilder in einem UIImageView Array zu posten?

func uploadImage() 
{ 
    let postPictureUrl = NSURL(string: "http://www.23look.com/merchant/verify") 
    let request = NSMutableURLRequest(URL: postPictureUrl!) 
    request.HTTPMethod="POST" 

    let param=[ 
     "mer_name" : shopNameUITF.text!, 
     "mer_tel" : shopTelephoneUITF.text!, 
     "mer_address" : shopAddressUITF.text!, 
     "lat" : "39.6892", 
     "lng" : "115.9239", 
     "token": KeychainWrapper.stringForKey("tokenValue")!, 
     "mer_type": "smalll" 
    ] 

    let abc = KeychainWrapper.stringForKey("tokenValue")! 

    let boundary = generateBoundaryString() 

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

    let imageData = UIImageJPEGRepresentation(myImageView.image!, 0.1) 

    if imageData==nil { print("image data is nil"); return } 

    request.HTTPBody = createBodyWithParameters(param, filePathKey: "mer_license", imageDataKey: imageData!, boundary: boundary) 

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { 
     data, response, error in 

     if error != nil { 
      print("error=\(error)") 
      return 
     } 

     //You can print out response object 
     print("***** response = \(response)") 

     // Print out reponse body 
     let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding) 
     print("**** response data = \(responseString!)") 

     do { 

      let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary 

      dispatch_async(dispatch_get_main_queue(), { 
       print(NSString(data: data!, encoding:NSUTF8StringEncoding)!) 
       print(json) 
      }) 

     } catch let err { 
      print(err) 
     } 
    } 
    task.resume() 
} 

func generateBoundaryString() -> String { 
    return "Boundary-\(NSUUID().UUIDString)" 
} 

func createBodyWithParameters(parameters:[String:String]?, filePathKey: String?, imageDataKey:NSData, boundary: String) -> NSData { 

    var body=NSMutableData() 

    if parameters != nil { 
     for(key, value) in parameters! { 
      body.appendString("--\(boundary)\r\n") 
      body.appendString("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n") 
      body.appendString("\(value)\r\n") 
     } 
    } 

    let filename = "user-profile.jpg" 
    let mimetype = "image/jpg" 

    body.appendString("--\(boundary)\r\n") 
    body.appendString("Content-Disposition: form-data; name=\"\(filePathKey!)\"; filename=\"\(filename)\"\r\n") 
    body.appendString("Content Type: \(mimetype)\r\n\r\n") 
    body.appendData(imageDataKey) 
    body.appendString("\r\n") 

    body.appendString("-\(boundary)-\r\n") 

    return body 
} 

Es nimmt folgende Parameter:

mer_name - String

mer_tel - String

mer_address - String

lng - String

lat - String

mer_licence - Dateityp (Dies ist, wo meine Bilder hochgeladen werden)

Token - String

mer_type - String

Sie sollten wie unten in createBodyWithParameters Änderungen tun ....... ..

Wenn Sie mehrere Bilder haben ...

func createBodyWithParameters(parameters: NSMutableDictionary?,boundary: String) -> NSData { 
    let body = NSMutableData() 

    if parameters != nil { 
     for (key, value) in parameters! { 

      if(value is String || value is NSString){ 
       body.appendString("--\(boundary)\r\n") 
       body.appendString("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n") 
       body.appendString("\(value)\r\n") 
      } 
      else if(value is [UIImage]){ 
       var i = 0; 
       for image in value as! [UIImage]{ 
        let filename = "image\(i).jpg" 
        let data = UIImageJPEGRepresentation(image,1); 
        let mimetype = mimeTypeForPath(filename) 

        body.appendString("--\(boundary)\r\n") 
        body.appendString("Content-Disposition: form-data; name=\"\(key)\"; filename=\"\(filename)\"\r\n") 
        body.appendString("Content-Type: \(mimetype)\r\n\r\n") 
        body.appendData(data!) 
        body.appendString("\r\n") 
        i++; 
       } 


      } 
     } 
    } 
    body.appendString("--\(boundary)--\r\n") 
    //  NSLog("data %@",NSString(data: body, encoding: NSUTF8StringEncoding)!); 
    return body 
} 

func generateBoundaryString() -> String { 
    return "Boundary-\(NSUUID().UUIDString)" 

} 

func mimeTypeForPath(path: String) -> String { 
    let pathExtension = path.pathExtension 
    var stringMimeType = "application/octet-stream"; 
    if let uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension!, nil)?.takeRetainedValue() { 
     if let mimetype = UTTypeCopyPreferredTagWithClass(uti, kUTTagClassMIMEType)?.takeRetainedValue() { 
      stringMimeType = mimetype as NSString as String 
     } 
    } 
    return stringMimeType; 
} 



func createRequest (param : NSMutableDictionary , strURL : String) -> NSURLRequest { 

    let boundary = generateBoundaryString() 

    let url = NSURL(string: strURL) 
    let request = NSMutableURLRequest(URL: url!) 

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

    return request 
}
