我一直在玩,Codable并从文件中读取和写入JSON.现在我想写一个Coder可以读写iOS .strings文件的自定义.谁能帮我这个?我发现协议Encoder和Decoder,但我不知道我应该实现此:
class StringsEncoder {}
extension StringsEncoder: Encoder {
var codingPath: [CodingKey?] {
return []
}
var userInfo: [CodingUserInfoKey : Any] {
return [:]
}
func container<Key>(keyedBy type: Key.Type) -> KeyedEncodingContainer<Key> where Key : CodingKey {
}
func unkeyedContainer() -> UnkeyedEncodingContainer {
}
func singleValueContainer() -> SingleValueEncodingContainer {
}
}
extension StringsEncoder: Decoder {
func container<Key>(keyedBy type: Key.Type) throws -> KeyedDecodingContainer<Key> where Key : CodingKey {
}
func unkeyedContainer() throws -> …Run Code Online (Sandbox Code Playgroud) 我尝试了很多解决方案。我得到了一些,但他们正在objective c code某个地方使用。我只需要在swift 4.2没有任何第三方的情况下(例如Alamofire)的解决方案objective c。使用class 可以很好地工作。
我已经能够仅使用标头,其他参数和图像发出POST请求,如下所示:
多部分表单(图像,参数,标题),快速与Alamofire一起发布请求
func sendFile(
urlPath:String,
fileName:String,
data:NSData,
completionHandler: (NSURLResponse!, NSData!, NSError!) -> Void){
var url: NSURL = NSURL(string: urlPath)!
var request1: NSMutableURLRequest = NSMutableURLRequest(URL: url)
request1.HTTPMethod = "POST"
let boundary = generateBoundary()
let fullData = photoDataToFormData(data,boundary:boundary,fileName:fileName)
request1.setValue("multipart/form-data; boundary=" + boundary,
forHTTPHeaderField: "Content-Type")
// REQUIRED!
request1.setValue(String(fullData.length), forHTTPHeaderField: "Content-Length")
request1.HTTPBody = fullData
request1.HTTPShouldHandleCookies = false
let queue:NSOperationQueue = NSOperationQueue()
