在IOS中上载带参数的多部分图像

我是新的IOS n想要上传的图像与参数到服务器，但它没有上传。我尝试了很多关于alamofire和base64的参考资料，但都不适合我。我是否错过了任何东西，任何有助于理解这一点的东西

提前谢谢。请帮我解决这个问题

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，然后您将能够发送图像数据，并增加会话请求的超时时间间隔manager.session.configuration.timeoutitervalforrequest=120，如果您有任何疑问，请回复我，我将尝试解决您的问题问题

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
    }
}}}  

class-func-requestForAPI（参数：Dictionary？、Url:String、image:UIImage、isShowLoader:Bool、headers:[String:String]？、完成：@escaping（\uresult:AnyObject？、\uerror:error？）->Void）{
let reach:Reachability=Reachability.forInternetConnection（）
让netStatus:NetworkStatus=reach.currentReachabilityStatus（）
if（netStatus==NotReachable）
{
NSUtility.shared（）.showMessage（标题：“警报！”，正文：“请连接到internet以继续”，主题：。错误）
返回
}
如果isShowLoader==真{
APPDELEGATE？.showLoaderView（）
}
让manager=Alamofire.SessionManager.default
manager.session.configuration.timeoutitervalforrequest=120
让imageData=image.jpegData（压缩质量：0.8）
manager.upload（multipartFormData:
{
（multipartFormData）在
为参数中的（键，值）追加（imageData，名称：“file”，文件名：“file.jpeg”，mimeType：“image/jpeg”）{
multipartFormData.append（value.data（使用：String.Encoding.utf8.rawValue）！，名称：key）
}，收件人：URL（字符串：URL）！，方法：。放置，标题：标题）
(结果)
切换结果{
成功案例（让我们上传，，u）：
uploadProgress（闭包：{（进度）在
//打印进度
})
upload.responseJSON
{答复
APPDELEGATE？.dismissLoader（）
//打印响应结果
如果response.result.value！=nil
{
打印（response.result.value，如有）
完成（response.result.value为AnyObject？，无）
}
}
案例失败（let encodingError）：
打印（编码错误）
完成（无，编码错误）
打破
}
}}}  

您能告诉我错误吗？你们能上传完整的代码以便我调试吗？在这里发布之前，请正确格式化你们的代码。在请求中添加HttpMethod。您可以在标题中尝试“内容类型：Multipart/*”。

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
    }
