swift - 如何将字符串转换为json字典？

Question

下面的代码，我用来将字符串转换为字典，但不起作用。

let body = "{status:0}"
do {
    let dictionary = try convertToDictionary(from: body ?? "")
    print(dictionary) // prints: ["City": "Paris"]
} catch {
    print(error)
}

func convertToDictionary(from text: String) throws -> [String: String] {
    guard let data = text.data(using: .utf8) else { return [:] }

    let anyResult: Any = try JSONSerialization.jsonObject(with: data, options: [])

    return anyResult as? [String: String] ?? [:]
}

Answer 1

由于输入字符串不是 json，我建议使用非 json 解决方案

let array = body.dropFirst().dropLast().split(separator: ":").map {String($0)} 

var dictionary = [String: String]()
if let key = array.first, let value = array.last { 
    dictionary[key] = value
}
