解析json字符串的时候

“{timeInterval=60, stepList=[0, 0, 0, 186, 1928, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 296, 0, 0, 0, 0, 0]}”

报错: 第一个字符应该是key的字符串

Error Domain=NSCocoaErrorDomain Code=3840 “No string key for value in object around character 1.” UserInfo={NSDebugDescription=No string key for value in object around character 1.}

原因

字符串不是标准的json字符串，标准的字符串应该长成下面的样子

 "{\"timeInterval\":60, \"stepList\":[0, 0, 0, 186, 1928, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 296, 0, 0, 0, 0, 0]}"

解析带等号（=）的json字符串

class C1StepModel:Decodable {
    var timeInterval:Int = 60
    var stepList:[Int] = [1,2]
    
}

    var jsonStr = "{timeInterval=60, stepList=[0, 0, 0, 186, 1928, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 296, 0, 0, 0, 0, 0]}"
    jsonStr = jsonStr.replacingOccurrences(of: "=", with: ":")
    jsonStr = jsonStr.replacingOccurrences(of: "timeInterval", with: "\"timeInterval\"")
    jsonStr = jsonStr.replacingOccurrences(of: "stepList", with: "\"stepList\"")

    let data:Data = jsonStr.data(using: .utf8)!
    let model = try! JSONDecoder().decode(C1StepModel.self, from: data)
