[英]Swift Image upload via HTTP $_POST
我正在使用以下代碼(Swift)將用戶從照片中選擇的圖像上傳到服務器:
let imageFormatted = UIImageJPEGRepresentation(imageView.image!, 0.5);
let uuid = NSUUID().UUIDString
print ("MARK -- UUID is " + uuid)
Alamofire.upload(
.POST,
"http://www.memer.onlie/upload.php",
multipartFormData: { multipartFormData in
multipartFormData.appendBodyPart(data: imageFormatted!, name: "imagefile",
fileName: uuid + ".jpg", mimeType: "image/jpeg")
},
encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.validate()
upload.responseJSON { response in
dispatch_async(dispatch_get_main_queue()) {
self.displayAlert("Uploaded!", message: "Your meme was uploaded, and you might see it in the app soon!", responseButtonText: "<3")
}
var json = JSON(data: response.data!)
print ("MARK -- JSON response: " + json["response"].stringValue)
}
print ("MARK -- Upload success!")
case .Failure(let encodingError):
print(encodingError)
print ("MARK -- Upload failure!")
self.displayAlert("Issue uploading.", message: "There was an issue uploading your meme.", responseButtonText: "Aww :(")
}
}
)
沒有圖像上傳到服務器。 我該如何糾正才能正常工作?
編輯的代碼。
該線程可幫助您了解尚未考慮的內容以及解決該問題所需要做的事情。 我猜您需要正確設置請求標頭和正文部分。 如果您使用Alamofire並且必須使用“ multipart / form-data”編碼類型,則可以編寫這樣的代碼。
Alamofire.upload(.POST, destURL, headers: yourHeader, multipartFormData: { multipartFormData in
if let imageData = UIImageJPEGRepresentation(image, 0.5) {
multipartFormData.appendBodyPart(data: imageData, name:"file", fileName: "imagefile", mimeType: "image/jpg")
}
// Append parameters you should send
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
}, encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.validate()
upload.responseJSON { response in
// do something if response is success
}
case .Failure(_):
// do something if response is fail
}
})
