Alamofire零件请求 [英] Alamofire Multipart request

问题描述

我是快速编程的新手.我正在尝试通过alamofire进行Multipart请求.问题是我参数中的值之一是对象数组.我的问题是如何将对象数组追加到Multipart请求. 这是我的参数.

I am new to swift programming. i am trying do Multipart request via alamofire .Issue is that one of value in my parameters is array of objects. My Question is how to append array of object to Multipart request. Here are my parameters.

 let parameters = [
        "originguid":"63d6sd5",
        "signees":[Signess], //Here is issue "signees"is an array of objects
        "customer":"yes"
        ] as [String : Any]

这是我的要求

Alamofire.upload(
    .POST,
    URLString: myUrl,
    multipartFormData: { multipartFormData in

        if let img = self.imagePicked {
            multipartFormData.append(UIImageJPEGRepresentation(img, 0.2)!, withName: "fileset",fileName: "file.png", mimeType: "image/jpg")
        }
        if let file = self.filePicked{
            let fileData = try! Data(contentsOf: file)
            multipartFormData.append(fileData as Data, withName:"test.pdf", mimeType:"application/pdf")
        }

        for (key, value) in parameters {

            if key == "signees"{
                   multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
            }

            else{
                multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
            }


        }

    },

    ...
)

将签署人附加到多部分请求时，应用程序崩溃. 这是我在参数中使用的对象.

Application crashes when appending signees to multipart request. Here is my Object that i am using in parameters.

class Signee: NSObject, NSCoding {
var name = ""
var email = ""
var phoneNo = ""
func encode(with aCoder: NSCoder) {
    aCoder.encode(name, forKey: "name")
    aCoder.encode(email, forKey: "email")
    aCoder.encode(phoneNo, forKey: "phoneNo")
}
init(name: String, email: String, phone: String) {
    self.name = name
    self.email = email

    self.phoneNo = phone

}
required convenience init(coder aDecoder: NSCoder) {
    let name = aDecoder.decodeObject(forKey: "name") as! String
    let email = aDecoder.decodeObject(forKey: "email") as! String
    let phoneNo = aDecoder.decodeObject(forKey: "phoneNo") as! String
    self.init(name: name, email: email, phone: phoneNo)
}}

请帮助.在此先感谢您，我浪费了两天时间尝试不同的事情.

Please help. Thanks in advance, i have wasted two days trying different things.

推荐答案

使用almofire

数据分成多部分发送

struct AGImageInfo {
    var fileName: String
    var type: String
    var data: Data
}

请求

let header: HTTPHeaders = [
    "Content-Type":"application/x-www-form-urlencoded"
]

let parameters: Parameters = [
    "someParam": "value",
    "Image": AGImageInfo(fileName: "nameOfImage.jpeg", type: "image/jpeg", data: #imageLiteral(resourceName: "TO").toData()!)
]

Alamofire.upload(multipartFormData: { (multipartFormData) in

    for (key, value) in parameters {
        if let imageData = value as? AGImageInfo {
            multipartFormData.append(imageData.data, withName: key, fileName: imageData.fileName, mimeType: imageData.type)
        }
        multipartFormData.append(((value as AnyObject).data(using: String.Encoding.utf8.rawValue))!, withName: key)
    }

}, to: "URL", method: .post, headers: header) { (result) in

    switch result {
    case .success(let upload, _, _):

        upload.responseJSON { response in
            switch response.result {
            case .success(let value):
                debugPrint(value)
                break

            case .failure(let error):
                debugPrint(error)
                break
            }
        }

    case .failure(let error):
        debugPrint(error)
        break
    }
}
