Question

如何解析多于一个以空字符结尾的JSON（通过套接字TCP / IP）。

{"ObjectID":"UHJvY1dpcmVsZXNzTXNn","DeviceCode":"RUNEOjI=","ActiveInputNames":"Q2hlY2sgaW4gRmFpbA==","DeviceInputNo":"999999","Activation":false,"Reset":true,"LocationID":"","LocationGroupText":"","ProtocolText":"","CallBackNo":"OTE5MTgyNTcyMjQ5"}��{"ObjectID":"VFBpbmdPYmplY3Q="}��

您可以看到上面的响应，其中有2个JSON以空字符结尾...我可以轻松解析单个JSON，但无法解析多个JSON。

如果有人提出任何解决方案，那就太好了！

Answer 1

我昨天在Android系统中回答了same question。这是Swift版本

let s = "{\"ObjectID\":\"UHJvY1dpcmVsZXNzTXNn\",\"DeviceCode\":\"RUNEOjI=\",\"ActiveInputNames\":\"Q2hlY2sgaW4gRmFpbA==\",\"DeviceInputNo\":\"999999\",\"Activation\":false,\"Reset\":true,\"LocationID\":\"\",\"LocationGroupText\":\"\",\"ProtocolText\":\"\",\"CallBackNo\":\"OTE5MTgyNTcyMjQ5\"}��{\"ObjectID\":\"VFBpbmdPYmplY3Q=\"}��".components(separatedBy: "��")


            for string in s{
                // do your parsing here
                print(string)
            }

您需要做的只是用^分割字符串，您就可以开始了。像以前一样解析JSON。

首先使用components(separatedBy:)将这两个JSON分开，以便我们可以分别解析它们。

let str = """
{"ObjectID":"UHJvY1dpcmVsZXNzTXNn","DeviceCode":"RUNEOjI=","ActiveInputNames":"Q2hlY2sgaW4gRmFpbA==","DeviceInputNo":"999999","Activation":false,"Reset":true,"LocationID":"","LocationGroupText":"","ProtocolText":"","CallBackNo":"OTE5MTgyNTcyMjQ5"}��{"ObjectID":"VFBpbmdPYmplY3Q="}��
"""
let jsonArr = str.components(separatedBy: "��")

jsonArr包含 JSON Strings 。让我们看看如何解析它们。

我们将使用 Codable 使用以下模型解析两个 JSON 。

struct Root: Codable {
    let objectID: String
    let deviceCode: String?
    let activeInputNames: String?
    let deviceInputNo: String?
    let activation: Bool?
    let reset: Bool?
    let locationID: String?
    let locationGroupText: String?
    let protocolText: String?
    let callBackNo: String?

    enum CodingKeys: String, CodingKey {
        case objectID = "ObjectID"
        case deviceCode = "DeviceCode"
        case activeInputNames = "ActiveInputNames"
        case deviceInputNo = "DeviceInputNo"
        case activation = "Activation"
        case reset = "Reset"
        case locationID = "LocationID"
        case locationGroupText = "LocationGroupText"
        case protocolText = "ProtocolText"
        case callBackNo = "CallBackNo"
    }
}

解析 JSON个字符串，例如

let parsedObjs = jsonArr.map { (str) -> Root? in
    if let data = str.data(using: .utf8) {
        do {
            let obj = try JSONDecoder().decode(Root.self, from: data)
            return obj
        } catch {
            print(error)
            return nil
        }
    }
    return nil
}

parsedObjs将包含两个 JSON Root 的解析的strings对象。

请让我知道是否还有任何困惑。
