Question

我正在尝试使用“ Alamofire 5.2）将多个图像和参数上传到服务器这就是服务器的期望

[{"key":"media1","description":"","type":"file","value":["/C:/Users/x/x/x/x.jpg"]},
[{"key":"media2","description":"","type":"file","value":["/C:/Users/x/x/x/x.jpg"]},
[{"key":"media3","description":"","type":"file","value":["/C:/Users/x/x/x/x.jpg"]},

{"key":"model","value":"{\"emp_Id\": \"6\",\"device_Identifier\":\"Device 01\",\"timestamp\":\"123\,”\description\”:\”description\",”handoverStatus”:”false”}","type":"text"}]

//Please note the array part

这是我将选择的图像添加到图像阵列的方式

var dictImage : [UIImage]?

if pickedImage.pngData() != nil
{
  dictImage!.append(pickedImage)
}

这就是我试图调用alamofire上传的方式

func xyz()
{
        let param : [String: Any] = [
            "emp_Id" : "",
            "device_Identifier" : "",
            "timestamp" : "",
            "description" : "",
            "handoverStatus" : ""
        ]
    let urlString = URL(string: APIDetails.BaseUrl + "api/123")!
    let url = (try? URLRequest(url: urlString, method: .post, headers: APIDetails.header))!
    AF.upload(multipartFormData: { (multipartData) in
        
        let img1 = arrImage![0]
        let img2 = arrImage![1]
        let img3 = arrImage![2]

        multipartData.append(img1.pngData(), withName:"media1", fileName: "\(Date().timeIntervalSince1970).jpg", mimeType: "file")
        multipartData.append(img2.pngData(), withName:"media2", fileName: "\(Date().timeIntervalSince1970).jpg", mimeType: "file")
        multipartData.append(img3.pngData(), withName:"media3", fileName: "\(Date().timeIntervalSince1970).jpg", mimeType: "file")
            
        
        for (key, value) in param {
            multipartData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
        }

    }, with: url)
}

如何将每张图片及其详细信息作为字典上传？

如何添加上传进度和结果以显示是否失败？

我尝试过


}, with: url,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)")

        }        })

但是它给出了错误Extra argument 'encodingCompletion' in call

（这是我第一次尝试上传多部分表单数据，其代码/部分来自另一个答案）

尝试此代码，我尚未在Alamofire（5.2）中进行测试

let baseUrl = "your URL"
    let fullUrl = baseUrl + strUrl
    var headers : HTTPHeaders = HTTPHeaders(["Content-type" : "multipart/form-data"])
    if let header = header{
        headers = header
    }
    
    guard let url = try? URLRequest(url: fullUrl, method: .post, headers: headers) else {return}
    AF.upload(multipartFormData: { (multipartData) in
        
        for i in 0 ..< arrImage.count{
            if let imageData = arrImage[i].pngData(){
                let mediaName = "media\(i + 1)"
                multipartData.append(imageData, withName:mediaName, fileName: "\(Date().timeIntervalSince1970).jpg", mimeType: "file")
            }
        }
      for (key, value) in parameter {
            multipartData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
        }
    }, to: url).responseJSON(queue: .main, options: .allowFragments) { (response) in
        switch response.result{
        case .success(let value):
            print("Json: \(value)")
        case .failure(let error):
            print("Error: \(error.localizedDescription)")
        }
    }.uploadProgress { (progress) in
        print("Progress: \(progress.fractionCompleted)")
    }
