考虑以下json:{"from":"Guille","text":"LookwhatIjustfound!","attachments":[{"type":"image","payload":{"url":"http://via.placeholder.com/640x480","width":640,"height":480}},{"type":"audio","payload":{"title":"NeverGonnaGiveYouUp","url":"https://audio.com/NeverGonnaGiveYouUp.mp3","shouldAutoplay":true,
我只需要为下面的类手动自定义一个编码键@objcMembersclassArticle:Object,Decodable{dynamicvarid:Int=0dynamicvartitle:String=""dynamicvarimage:String=""dynamicvarauthor:String=""dynamicvardatePublished:Date?dynamicvarbody:String?dynamicvarpublisher:String?dynamicvarurl:String?}所以我必须添加以下枚举privateenumCodingKeys:String,C
我从API获取JSON，并且大多数key都是开箱即用的。API响应示例:[{"href":"http:\/\/audiomachine.com\/","description":"Audiomachine","extended":"Musicforvideos","shared":"yes","toread":"no","tags":"creativevideomusic"},{"href":"https:\/\/www.root.cz\/clanky\/nekricte-na-disky-zvuk-i-ultrazvuk-je-muze-poskodit-nebo-zmast-cid
我正在使用URLSession的泛型和可编码。当我收到来自API的响应时，我检查状态是否在200-299范围内并像这样解码数据guardletdata=data,letvalue=try?JSONDecoder().decode(T.self,from:data)else{returncompletion(.error("CouldnotdecodeJSONresponse"))}completion(.success(value))然后将其传递给完成处理程序，一切正常。我有一个新的端点我也必须POST但是，这个端点返回一个没有内容主体的204。因此，我无法解码响应，就像我无法传入类型
你好我有如下的json数据{"data":[{"resolved":"N\/A","type":"Internal","notes":"test","property_id":"22","regulation_item":"8","locations":"Test","id":"45","boiler_service_date":"","action":"FurtherInvestigation\/MaintenanceRequired","intervention_required":"N\/A","regulation_id":"4","regulation_item_name":
关闭。这个问题需要detailsorclarity.它目前不接受答案。想改进这个问题吗？通过editingthispost添加细节并澄清问题.关闭5年前。Improvethisquestion如何处理来自JSON的可编码结构的字段，它可以是空字符串或整数？我尝试使用数据类型any但不符合可编码。我认为，如果它没有值，那么它会返回一个空字符串，否则，它会返回一个int。我正在使用Swift4和XCode9。提前致谢
我正在使用Codable的jsondecode.decode([User].self,from:jsonDataRaw)创建NSManagedObjects但我的问题是decode.decode()每次都会创建一个新对象，但我需要一种方法来使用jsonData更新现有对象而不是创建新对象。有没有办法使用Codable做到这一点？classUser:NSManagedObject,Codable{requiredconvenienceinit(fromdecoder:Decoder)throws{guardletcontextUserInfoKey=CodingUserInfoKey.c
CodingKey是否可以仅用于JSONEncoder而JSONDecoder使用默认成员名称？例子我有以下结构varstr="""{"name":"Endeavor","abv":8.9,"brewery":"SaintArnold","style":"ipa"}"""enumBeerStyle:String,Codable{caseipacasestoutcasekolsch}structBeer:Codable{letname:Stringletbrewery:Stringletstyle:BeerStyleletabv:Float//THISSHOULDBEUSEDONLYFO
我有这样的结构:structOrderLine:Codable{letabsUrl:String?letrestApiUrl:String?letdescription:String?letquantity:Int?letsubscription:Subs?lettotal:Double?}structSubs:Codable{letquantity:Int?letname:String?}一些OrderLine在服务器响应中有"subscription":{"quantity":6,"name":"3Months"},但有时它有String类型:"subscription":"",没
我正在使用swiftCodable解析这个API"total":7,"searchResult":[null,{"name":"joe""family":"adam"},null,{"name":"martin""family":"lavrix"},{"name":"sarah""family":"mia"},null,{"name":"ali""family":"abraham"}]使用这个PaginationModel:classPaginationModel:Codable{vartotal:Int?vardata:T?enumCodingKeys:String,CodingKe
