Question

我是IOS的新手，n要将带有参数的图像上传到服务器，但没有上传。我尝试了很多，同时推荐alamofire和base64，但没有任何工作对我有用。我是否想念任何东西，有什么帮助吗？

先谢谢了。请帮助我解决问题

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)
        }
    }
}

首先，您需要添加方法类型（即.post或.put类型以及url），然后才能发送图像数据，并增加会话 manager.session请求的超时间隔。 configuration.timeoutIntervalForRequest = 120 。如果您有任何疑问，请在同一时间回复我，以便我尝试解决您的问题。

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
    }
}}}
