在IOS中上传带参数的多部分图像

【中文标题】在IOS中上传带参数的多部分图像【英文标题】：Upload multipart image with parameters in IOS 【发布时间】：2019-01-11 06:52:26 【问题描述】：我是 ios 新手，想将带参数的图像上传到服务器，但没有上传。我尝试了很多参考 alamofire 和 base64，但没有什么对我有用。我有没有遗漏任何事情，对理解这一点有帮助吗？
提前致谢。请帮我解决问题
下面是我的代码：
@IBAction func submitBtnClicked(_ sender: Any)
//parameters
var number: Int?
number = 47000482
var srNumber = String(format:"%d",number!)
var urlString: String = filePath!.absoluteString
var parameters = ["s_no":srNumber, "count":"1"]
let imgData = UIImageJPEGRepresentation(self.chosenImage!, 0.5)
print(parameters)
print(imgData)
Alamofire.upload(multipartFormData: (multipartFormData) in
multipartFormData.append(imgData!, withName:"filestream", fileName:(self.filePath?.lastPathComponent)!, mimeType: "image/jpeg")
for (key, value) in parameters
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName:key)
, to:"https://********************")
(result) in
switch result
case .success(let upload, _, _):
upload.uploadProgress(closure: (Progress) in
print("Upload Progress: \(Progress.fractionCompleted)")
)
upload.responseJSON response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value
print("JSON: \(JSON)")
case .failure(let encodingError):
//self.delegate?.showFailAlert()
print(encodingError)
【问题讨论】：
你能告诉我错误吗？你能上传整个代码让我调试吗？ 在此处发布之前正确格式化您的代码。 在请求中添加 HttpMethod。您可以在标题中尝试“Content-Type：Multipart/*”。 【参考方案1】： //MARK: - Multiple Images Uploading API Call
func serviceUploadMultipleImageData(model : UploadImageResponseModel,isLoader:Bool = true,name:String = "", loaderViewcontoller : UIViewController? = nil,url: String, method: HTTPMethod, InputParameter: Parameters?, ServiceCallBack: @escaping (_ Completion: ServiceResponseNormal, _ isSuccess:Bool)-> Void)
let viewContoller = loaderViewcontoller
guard Reachability.isConnectedToNetwork() else
Singleton.sharedSingleton.showPopup(title: "No Internet", message: HttpCode.NoInternetConnection.message(), image: nil, VC: viewContoller!)
ServiceCallBack(self.setCustomResponse(Code: HttpCode.NoInternetConnection.rawValue, Message: "No Internet Connection"),false)
return
if isLoader == true
if viewContoller != nil
ProgressHUD.startLoading(onView: (viewContoller?.view)!)
else
ProgressHUD.startLoading(onView: appDelegate.window!)
Alamofire.upload(multipartFormData: (multipartFormData) in
for obj in model.arrImages
multipartFormData.append(obj.imageData!, withName:obj.imgName, fileName: "", mimeType: "image/jpg")
for (key, value) in InputParameter!
multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue, allowLossyConversion: true)!, withName: key)
, to:url)
(result) in
switch result
case .success(let upload, _, _):
upload.uploadProgress(closure: (Progress) in
model.progress = Progress.fractionCompleted
)
upload.responseJSON response in
if isLoader == true
if viewContoller != nil
ProgressHUD.stopLoading(fromView: (viewContoller?.view)!)
else
ProgressHUD.stopLoading(fromView: appDelegate.window!)
if(response.result.isSuccess)
print(response)
do
if response.data != nil
var responseParsed = try JSONDecoder().decode(ServiceResponseNormal.self, from: response.data!)
if responseParsed.Code == "200"
responseParsed.Data = response.data
ServiceCallBack(responseParsed, true)
else
Singleton.sharedSingleton.showPopup(title: "Error", message: responseParsed.Message ?? "Error", image: nil, VC: viewContoller!)
ServiceCallBack(responseParsed, false)
catch let error
print(error.localizedDescription)
var falilure = ServiceResponseNormal()
falilure.Data = nil
falilure.Message = "Response could not parsed"
ServiceCallBack(falilure, false)
else
if let error = response.result.error
let message = error.localizedDescription
var falilure = ServiceResponseNormal()
falilure.Data = nil
falilure.Message = message
ServiceCallBack(falilure, false)
Singleton.sharedSingleton.showPopup(title: "Error", message: message, image: nil, VC: viewContoller!)
case .failure(let encodingError):
let message = encodingError.localizedDescription
var falilure = ServiceResponseNormal()
falilure.Data = nil
falilure.Message = message
ServiceCallBack(falilure, false)
Singleton.sharedSingleton.showPopup(title: "Error", message: message, image: nil, VC: viewContoller!)

【参考方案2】：首先，您需要添加方法类型，即 .post 或 .put 类型以及 url，然后您将能够发送图像数据并增加会话请求的超时间隔manager.session。 configuration.timeoutIntervalForRequest = 120如果您有任何疑问，请回复我，我会尽力解决您的问题。
class func requestForAPI(param:Dictionary<String, String>?, Url:String,image:UIImage,isShowLoader:Bool, headers:[String:String]?, completion: @escaping (_ result: AnyObject?, _ error: Error?) -> Void)
let reach:Reachability = Reachability.forInternetConnection()
let netStatus:NetworkStatus = reach.currentReachabilityStatus()
if (netStatus == NotReachable)
NSUtility.shared().showMessage(title: "Alert!", body: "Please connect to the internet to continue", themetype: .error)
return
if isShowLoader == true
APPDELEGATE?.showLoaderView()
let manager = Alamofire.SessionManager.default
manager.session.configuration.timeoutIntervalForRequest = 120
let imageData = image.jpegData(compressionQuality: 0.8)
manager.upload(multipartFormData:
(multipartFormData) in
multipartFormData.append(imageData, withName: "file", fileName: "file.jpeg", mimeType: "image/jpeg") for (key, value) in param
multipartFormData.append(value.data(using:String.Encoding.utf8.rawValue)!, withName: key)
, to:URL(string: Url)!,method:.put, headers:headers)
(result) in
switch result
case .success(let upload,_,_ ):
upload.uploadProgress(closure: (progress) in
//Print progress
)
upload.responseJSON
response in
APPDELEGATE?.dismissLoader()
//print response.result
if response.result.value != nil
print (response.result.value as Any)
completion(response.result.value as AnyObject? , nil)
case .failure(let encodingError):
print(encodingError)
completion(nil, encodingError)
break
