用TwitterKit分析Swift中TwitterKit搜索响应

Question

我试图只获取twitter调用返回的文本、用户名和配置文件图像，并使用它们的引用：Twitter :搜索Tweets。我得到了一个真实的响应，并且可以按状态解析JSON，但是每个状态的内容似乎都是一种不是JSON的格式，因为每个“键”都不是引号，并且使用相等号来关联它的值。

有谁知道我怎样才能获得我最终得到的‘Stat’对象，并从中提取任何一个值？即使只是将其转换为字符串，我也可以使用字符串解析来提取它。这只是一个学习项目，它不需要花哨。

另外，对于我所看到的' JSON‘为什么实际上不遵循正常的JSON格式，任何解释都是有帮助的。

我正在使用TwitterKit来提出请求。对于swift和JSON解析，我是相当陌生的。这是我的代码：

    let client = TWTRAPIClient()
    let statusesShowEndpoint = "https://api.twitter.com/1.1/search/tweets.json"
    let params = ["q": "@formlabs", "result_type": "recent", "include_entities": "false", "count": "3"]
    var clientError : NSError?

    let request = client.urlRequest(withMethod: "GET", url: statusesShowEndpoint, parameters: params, error: &clientError)

    client.sendTwitterRequest(request) { (response, data, connectionError) -> Void in
        if connectionError != nil {
            print("Error: \(String(describing: connectionError))")
        }
        do {
            let json = try JSONSerialization.jsonObject(with: data!, options: []) as? [String: Any]
            //print(json)
            let statuses = json!["statuses"] as? [Any]
            let status = statuses![0]
            print(status)
        } catch let jsonError as NSError {
            print("json error: \(jsonError.localizedDescription)")
        }
    }

这是输出，当我打印出一种状态时，我似乎只能将其转换为任何状态。当我试图把它转换成字符串时，它会变成零。
