在Swift 2.0中将图像从iOS应用程序上传到服务器

Question

我正在使用iOS应用程序，在其中我必须将图像上传到服务器，而我正在使用swift 2.0。 下面是代码：

var tempImage：UIImage = info [UIImagePickerControllerOriginalImage]为！ UIImage myImage.image = tempImage

    print(tempImage)

    print([info])

    myImage.image = info[UIImagePickerControllerOriginalImage] as? UIImage
    self.dismissViewControllerAnimated(true, completion: nil)
    var imageData = UIImagePNGRepresentation(tempImage)

    // converting in base64
    let base64 = imageData?.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.Encoding64CharacterLineLength) as! AnyObject

    let url = NSURL(string: "www.google.com/myimage1/PNG")!

    let urlRequest = NSMutableURLRequest(URL: url)
    urlRequest.HTTPMethod = "POST"

    // Set the HTTP Body with the POST data
    let postDict = ["encodedImage": base64]

    urlRequest.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(postDict , options: [])

    urlRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")


    urlRequest.timeoutInterval = 600
    urlRequest.HTTPShouldHandleCookies = false
 //   urlRequest.setValue("application/json)", forHTTPHeaderField: "Content-Type")

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

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

        print("response = \(response)")

        let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
        print("responseString = \(responseString)")
    }
    task.resume()

但是我还没有成功。 我仍然收到以下错误响应。

错误=可选（错误域= NSURLErrorDomain代码= -1001“请求超时。” UserInfo = {NSUnderlyingError = 0x7fad5af61e20 {Error Domain = kCFErrorDomainCFNetwork Code = -1001“（null）” UserInfo = {_ kCFStreamErrorCodeKey = 60，_kCFStreamErrorDomainKey = 1} }，NSErrorFailingURLStringKey = www.google.com / myimage1 / PNG，NSErrorFailingURLKey = http://www.google.com/myimage1/PNG，_kCFStreamErrorDomainKey=1，_kCFStreamErrorCodeKey=60，NSLocalizedDescription=请求超时。}）

如果您已经从swift 2.0应用程序中的服务器上上传了图像，请帮帮我。

Answer 1

您需要更改文件

info.plist

，并将其与应用程序TextEdit一起添加，或使用xcode。

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    </dict>
</dict>

来自Xcode http://i.stack.imgur.com/tGsEK.png

，别忘了清理项目。 （cmd + Shift + K）

func uploadImageOne()
{
    var imageData = UIImagePNGRepresentation(imageView.image)

    if imageData != nil{
        var request = NSMutableURLRequest(URL: NSURL(string:"= Enter your image URL")!)
        var session = NSURLSession.sharedSession()

        request.HTTPMethod = "POST"

        var boundary = NSString(format: "---------------------------14737809831466499882746641449")
        var contentType = NSString(format: "multipart/form-data; boundary=%@",boundary)
      //  println("Content Type \(contentType)")
        request.addValue(contentType, forHTTPHeaderField: "Content-Type")

        var body = NSMutableData.alloc()

        // Title
         body.appendData(NSString(format: "\r\n--%@\r\n",boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
        body.appendData(NSString(format:"Content-Disposition: form-data; name=\"title\"\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
        body.appendData("Hello World".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)!)

        // Image
        body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
        body.appendData(NSString(format:"Content-Disposition: form-data; name=\"profile_img\"; filename=\"img.jpg\"\\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
        body.appendData(NSString(format: "Content-Type: application/octet-stream\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
        body.appendData(imageData)
        body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)



        request.HTTPBody = body


        var returnData = NSURLConnection.sendSynchronousRequest(request, returningResponse: nil, error: nil)

        var returnString = NSString(data: returnData!, encoding: NSUTF8StringEncoding)

        println("returnString \(returnString)")

    }
