我需要上传带有表单数据的图片，但我的图片始终没有发送到api
我的参数是这样的
nickname": "carex",
password: "mantap",
name : "Kopral Kapten",
nickname : "cobra",
email : "[email protected]",
birth_date : "1980-09-29",
gender : "m",
phone : "081908908890",
password : "Vb+2fzEf/kXZuHUPenfT+Q==",
city : "Malang",
picture: upload file
我的代码：
if let data = imageData {
let imageURL = imageUrl
let fileName = imageURL.absoluteString
let userId = UserDefaults.standard.object(forKey: "id") as! String
let token = UserDefaults.standard.object(forKey: "token") as! String
let Params : Parameters = [
"picture" : fileName
]
//filename is image
let headersku: HTTPHeaders = [
"Content-Type":"application/x-www-form-urlencoded",
"Authorization": "Bearer \(token)"
]
let base_Url = "https://dev.lenna.ai/lenna/public/api/dBmK5m/users/\(userId)"
// Start Alamofire
Alamofire.upload(multipartFormData:{ multipartFormData in
multipartFormData.append(data, withName: "image", fileName: fileName, mimeType: "image/jpeg")
for (key, value) in Params {
multipartFormData.append((value as! String).data(using: String.Encoding.utf8)!, withName: key )
}
},
usingThreshold:UInt64.init(),
to: base_Url,
method:.post,
headers: headersku,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
print(response)
self.userImg.image = image
}
case .failure(let encodingError):
print(encodingError)
}
})
}
试试这个，你需要将图像作为multipart发送，或者你需要在params字典中将图像作为数据格式附加
let image: UIImage? = self.uploadImg.image
let uploadDict = ["key":val] as [String:String]
Alamofire.upload(multipartFormData: { MultipartFormData in
let image :Data = (image?.jpegData(compressionQuality: 1))!
MultipartFormData.append(image, withName: "image" , fileName: "image.jpeg" , mimeType: "image/jpeg")
for(key,value) in uploadDict{
MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)}
}, to: "http://XXXXXXXXXXXXXXXX/uploadImage", encodingCompletion: {
EncodingResult in
switch EncodingResult{
case .success(let upload, _, _):
upload.responseJSON { response in
debugPrint("SUCCESS RESPONSE: \(response)")
}
case .failure(let encodingError):
print("ERROR RESPONSE: \(encodingError)")
}
})
试试这个，您可以在正文中添加其他参数
func uploadImage(image: UIImage)
{
let url = URL(string: "URL_TO_PHP_SERVER");
let request = NSMutableURLRequest(url: url!)
request.httpMethod = "POST"
let boundary = generateBoundaryString()
//define the multipart request type
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
let image_data = UIImageJPEGRepresentation(image, 1)
if(image_data == nil)
{
print("problem occurred")
return;
}
let body = NSMutableData();
let date = Date();
let fname = "\(Int64(date.timeIntervalSince1970*1000)).jpg"
print("file name: \(fname)");
let mimetype = "image/jpeg"
//define the data post parameter
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("hi\r\n".data(using: String.Encoding.utf8)!)
body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
body.append("Content-Disposition:form-data; name=\"file\"; filename=\"\(fname)\"\r\n".data(using: String.Encoding.utf8)!)
body.append("Content-Type: \(mimetype)\r\n\r\n".data(using: String.Encoding.utf8)!)
body.append(image_data!)
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 = NSURLSession.sharedSession()
var configuration = URLSessionConfiguration.default;
var session = URLSession(configuration: configuration, delegate: self, delegateQueue: OperationQueue.main);
let task = session.dataTask(with: request as URLRequest) {
(
data, response, error) in
guard let _:Data = data, let _:URLResponse = response, error == nil else {
print("error")
DispatchQueue.main.async {
print("Problem occurred in uploading");
// DO your stuff in UI Thread
}
return
}
DispatchQueue.main.async {
print("uploading success");
// DO your stuff in UI Thread
}
let dataString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
print(dataString)
}
task.resume()
}
您需要在params字典中将图像作为multipart发送
import Alamofire
func tempImageShareToApi(){
let apiURL = "http://testApp/public/api/user/profile"
let params : [String: String] = [
"id" : "\(UserId)"
]
print(params)
Alamofire.upload(multipartFormData: { (multipartFormData) in
if let normalImg = self.userImageView {
if let imgValue = (self.pickedImage?.jpegData(compressionQuality: 0.75)) {
let r = arc4random()
let str = "file"+String(r)+".jpg"
let parameterName = "image"
multipartFormData.append(imgValue, withName:parameterName, fileName:str, mimeType: "image/jpeg")
}
}else{}
for (key, value) in params {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key )
}
}, to: apiURL,encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
if let Json = response.result.value as? Dictionary<String,AnyObject> {
print(Json)
if let responcCode = Json["data"] as? Dictionary<String,AnyObject>{
print(responcCode)
}
}
}
case .failure(let encodingError):
print(encodingError)
}})
}
你能试试这个吗，它会对你有所帮助。
创建图像字典： -
let dictimage = NSMutableDictionary()
dictimage.setValue("pass here Image data", forKey: "pass your image parameter name")
你的其他字段参数如
let dictparam = NSMutableDictionary()
dictparam.setValue("carex", forKey:"nickname")
dictparam.setValue("mantap", forKey:"password")
叫这个功能
class func callAPIWithMultiPart(_ url: String,
image:NSDictionary,
param: NSDictionary,
type : HTTPMethod,
controller: UIViewController,
header : [String: String]?,
callSilently : Bool = false,
successBlock: @escaping (_ responseDict: NSDictionary? , _ response: NSArray?) -> Void,
failureBlock: @escaping (_ error: Error? , _ isTimeOut: Bool) -> Void) {
if isNetworkAvailable() {
if !callSilently {
MBProgressHUD.showAdded(to: (UIApplication.shared.delegate?.window!)! , animated: true)
}
let urlWithUTF8 = url.addingPercentEncoding(withAllowedCharacters:NSCharacterSet.urlQueryAllowed)
print("**************************************************")
print("URL : \(urlWithUTF8!)")
print("Header : \(String(describing: header))")
print("Parameter For video : \(video.count)")
print("Parameter : \(param)")
Alamofire.upload(multipartFormData: { (multipartFormData) in
let arrParametersKey = NSMutableArray(array: param.allKeys)
let arrParametersValues = NSMutableArray(array: param.allValues)
//For normal Parameters
for index in 0 ..< arrParametersKey.count {
if let strKey = arrParametersKey.object(at: index) as? String , let strValue = arrParametersValues.object(at: index) as? String {
print("********************* MultiPart ******************")
print("strKey : \(strKey)")
print("strValue : \(strValue)")
multipartFormData.append(strValue.data(using: .utf8)!, withName: strKey)
}
}
//For File
if let strFileKeyForWebservices = video.value(forKey: "FileKeyForWebservices") as? String, let strFileName = video.value(forKey: "FileName") as? String, let dataForWebservices = video.value(forKey: "FileData") as? Data, let strFileMineType = video.value(forKey: "FileMineType") as? String {
print("********************* MultiPart File ******************")
print("FileKeyForWebservices : \(strFileKeyForWebservices)")
print("strFileName : \(strFileName)")
print("dataForWebservices : \(dataForWebservices.count)")
print("strFileMineType : \(strFileMineType)")
multipartFormData.append(dataForWebservices, withName: strFileKeyForWebservices, fileName: strFileName, mimeType: strFileMineType)
}
}, usingThreshold: UInt64.init(), to: urlWithUTF8!, method: type, headers: header) { (encodingResult) in
switch encodingResult {
case .success(let upload, _, _):
if !callSilently {
DispatchQueue.main.async {
MBProgressHUD.hide(for: ((UIApplication.shared.delegate?.window)!)!, animated: true)
}
}
upload.responseJSON { response in
print("Response : \(String(describing: response.response?.statusCode))");
if let aDict = response.result.value as? NSDictionary {
successBlock(aDict,nil)
} else if let aArray = response.result.value as? NSArray {
successBlock(nil,aArray)
} else {
failureBlock(nil, true)
}
}
break
case .failure(let encodingError):
if !callSilently {
DispatchQueue.main.async {
MBProgressHUD.hide(for: ((UIApplication.shared.delegate?.window)!)!, animated: true)
}
}
UIAlertController.showAlertWithOkButton(controller, aStrMessage: Localization("alert_SomethingWentWrong") , completion: nil)
failureBlock(encodingError, false)
break
}
}
} else {
// Internet is not connected
UIAlertController.showAlertWithOkButton(controller, aStrMessage: "Internet is not available", completion: nil)
let aErrorConnection = NSError(domain: "InternetNotAvailable", code: 0456, userInfo: nil)
failureBlock(aErrorConnection as Error , false)
}
}
如何使用
self.callAPIWithMultiPart("here apiURL", image: dictimage, param: dictparam, type: .post, controller: controller, header: requestHeader, successBlock: successBlock, failureBlock: failureBlock)
