json - 使用 TwitterKit 在 Swift 中解析 Twitter API 搜索响应

Question

我试图仅获取文本、用户名，以及稍后由 twitter API 调用返回的推文的个人资料图像，使用它们的引用:Twitter API: Search Tweets 。我已经得到了真实的响应，并且可以按状态解析 JSON，但每个状态的内容似乎都不是 JSON 的格式，因为每个“键”都不在引号中，而是使用等号进行关联具有它的值(value)。

有谁知道我如何获取最终得到的“状态”对象并提取任何值？即使只是将其转换为字符串，我也可以使用字符串解析将其提取出来。这只是一个学习项目，不需要很花哨。

此外，任何关于为什么我正在查看的“JSON”实际上并不遵循正常 JSON 格式的解释都会有所帮助。

我正在使用 TwitterKit 来发出请求。我对 swift 和 JSON 解析相当陌生。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)")
        }
    }

这是我打印一个状态时的输出，我只能将其转换为 Any。当我尝试转换为字符串时，它返回 nil。
