如何快速编写正确的JSON字符串文件

Question

我创建了一个JSON字符串文件，其中包含

{
[{"teamName":"Arsenal",
 "image":"Arsenal",
 "nextMatch":"in 2 days",
 "matches":[{"oppositeTeam":"teamName",
            "matchTimings":"121212",
            "matchId":"ID 213432"},
            {"oppositeTeam":"teamName",
            "matchTimings":"121212",
            "matchId":"ID 213432"}],

 "fixtures": {"oppositeTeam":"teamName",
 "oppositeTeamScore":"7",
 "homeTeamScore":"4",
 "homeTeamCards":"True",
 "oppositeTeamCards":"false",
 "fixtureId":"ID 213432”}
 }},
 {"teamName":"Chelsea",
 "image":"Chelsea",
 "nextMatch":"in 2 days",
 "matches":{"oppositeTeam":"teamName",
            "matchTimings":"121212",
            "matchId":"ID 213432"},

 "fixtures": {"oppositeTeam":"teamName",
 "oppositeTeamScore":"7",
 "homeTeamScore":"4",
 "homeTeamCards":"True",
 "oppositeTeamCards":"false",
 "fixtureId":"ID 213432”}
 }},{
 "teamName":"India",
 "image":"India",
 "nextMatch":"in 2 days",
 }
 ] }

但是当我在在线Json Reader上检查此JSON时，它显示了很多错误，我是JSON解析的新手，不知道如何更正JSON

Answer 1

正确的JSON语法：

{
   "teams":[
      {
         "teamName":"Arsenal",
         "image":"Arsenal",
         "nextMatch":"in 2 days",
         "matches":[
            {
               "oppositeTeam":"teamName",
               "matchTimings":"121212",
               "matchId":"ID 213432"
            },
            {
               "oppositeTeam":"teamName",
               "matchTimings":"121212",
               "matchId":"ID 213432"
            }
         ],
         "fixtures":{
            "oppositeTeam":"teamName",
            "oppositeTeamScore":"7",
            "homeTeamScore":"4",
            "homeTeamCards":"True",
            "oppositeTeamCards":"false",
            "fixtureId":"ID 213432"
         }
      },
      {
         "teamName":"Chelsea",
         "image":"Chelsea",
         "nextMatch":"in 2 days",
         "matches":{
            "oppositeTeam":"teamName",
            "matchTimings":"121212",
            "matchId":"ID 213432"
         },
         "fixtures":{
            "oppositeTeam":"teamName",
            "oppositeTeamScore":"7",
            "homeTeamScore":"4",
            "homeTeamCards":"True",
            "oppositeTeamCards":"false",
            "fixtureId":"ID 213432"
         }
      },
      {
         "teamName":"India",
         "image":"India",
         "nextMatch":"in 2 days"
      }
   ]
}

您的错误没有整个数组的键，请在matchIds的结尾处使用印刷术引号和多余的右花括号。

我想学习，以便将来自己能做

好吧，要写出有效的JSON 100％而没有任何大问题，我建议Codable ，

现在，对于任何手动或本地编写的JSON ，我将

1-创建一个结构以确认Codable 。

2-创建该Object的实例。

3-对该对象进行Encode ，然后将其转换为String ，它将100％确认为JSON验证程序。

观察下面的代码。

struct MyOject: Codable {
    var param1: String
    var param2: Int
    var param3: String
}

let myObj = MyOject(param1: "foo", param2: 1, param3: "bee")
let encodedData = try! JSONEncoder().encode(myObj) // encode the object as JSON Data
let myJSON = String(data:encodedData, encoding: .utf8)! // converting to String that is indeed JSON formatted
print(myJSON)

//Now to use it as object again we just need to Decode it. (the data)

let myObjResult = try! JSONDecoder().decode(MyOject.self, from: encodedData) // converted back as object
print(myObj.param1) // test reuslt should be (foo)

现在有什么好处

1-最重要的事情是可重用性，您可以根据需要进行多次重用。

2-100％有效的JSON提供程序。

3-为您提供将来处理任何API Responses技能。

4-到目前为止，这是最简单，最快的方法。
