如果JSON数据包含换行符(&Q；)，则SWIFT 4无法正确解码 (&Q；) [英] Swift 4 can't decode properly if json data contain new line (" ")

问题描述

如果json数据包含新行("")，则SWIFT 4无法正确解码 ")。我能为这个案例做些什么。请查看我的样例代码：

var userData = """
[
 {
  "userId": 1,
 "id": 1,
 "title": "Title 
 with newline",
 "completed": false
 }
]
""".data(using: .utf8)

struct User: Codable{
var userId: Int
var id: Int
var title: String
var completed: Bool
 }

do {
//here dataResponse received from a network request
let decoder = JSONDecoder()
let model = try decoder.decode([User].self, from:userData!) //Decode JSON Response Data
    print(model)
} catch let parsingError {
    print("Error", parsingError)
}

如果我按如下所示更改用户数据值，则它可以正确解码。

var userData = """
[
     {
      "userId": 1,
     "id": 1,
     "title": "Title \n with newline",
     "completed": false
     }
]
""".data(using: .utf8)

推荐答案

这是无效的json。 "" [ { "userid"：1， "id"：1， "title"："标题 带换行符"， "Complete"：False } ] "

请使用以下代码

var userData : [[String:Any]] =
[
 [
   "userId": 1,
   "id": 1,
   "title": "Title 
 with newline",
   "completed": false
 ]
]

struct User: Codable{
    var userId: Int
    var id: Int
    var title: String
    var completed: Bool
 }

do {
   //here dataResponse received from a network request
    let data = try? JSONSerialization.data(withJSONObject: userData, options: 
[])

    let decoder = JSONDecoder()
    let model = try decoder.decode([User].self, from:data!) //Decode JSON 
    Response Data
    print(model)
} catch let parsingError {
   print("Error", parsingError)
}
