错误（错误域= NSCocoaErrorDomain代码= 3840“字符0周围的值无效。”UserInfo = {NSDebugDescription =字符0周围的值无效。}

Question

我收到此错误为JSON result.error。虽然我的JSON是有效的，但请在线查看JSON vaildator。

这是我的JSON请求代码。

Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON)
                .responseJSON { (request, response, result) in
                    hud.hide(true)
                    // Set flag to disale poor internet connection alert
                    weakInternet = false
                    print(result.error)
                    if (result.value != nil) {
                        print("API Response: \(result.value!)")
                        // Pass the response JSON to the completion block
                        completion(json: result.value!)
                    } else {
                        // Response JSON is NULL
                    }
            }

当我点击具有特定请求参数的相同服务时，我收到了此响应。

有人知道我的问题是什么？

Answer 1

我的网络服务存在问题。他们以“text / HTML”格式而不是HTML格式给我回复。当我在调试器上打印我的响应时，我得到了：

"Content-Type" = "text/html; charset=UTF-8";

现在，我更新了我的网络服务，一切都像魅力一样。

Answer 2

我上次得到同样的错误，因为会有问题是web服务返回我在数组中的响应，我正在尝试将其转换为字典并提取其值。

检查您的网络服务响应。

Answer 3

Swift 5，Swift 4

var headers = HTTPHeaders()
    headers = [
        "Content-Type" :"text/html; charset=UTF-8",
        //"Content-Type": "application/json",
        //"Content-Type": "application/x-www-form-urlencoded",
        //"Accept": "application/json",
        "Accept": "multipart/form-data"
    ]

Answer 4

我在使用错误 Firebase Server 密钥发送远程推送通知时遇到此错误。

转到Firebase > Project Overview > CogIcon > Project Settings > Cloud Messaging > Server Key

guard let url = URL(string: "https://fcm.googleapis.com/fcm/send") else { return }    

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = try?

let paramDict = [String:Any]() // this has values
JSONSerialization.data(withJSONObject: paramDict, options: [])
request.setValue("application/json", forHTTPHeaderField: "Content-Type")

let serverKey = "firebase server key" // *** SERVER KEY USED HERE ***
request.setValue("key=\(serverKey)", forHTTPHeaderField: "Authorization")

let task = URLSession.shared.dataTask(with: request)  { (data, response, error) in

    do {
        if let jsonData = data {
                    
            if let jsonDataDict = try JSONSerialization.jsonObject(with: jsonData, options: JSONSerialization.ReadingOptions.allowFragments) as? [String: AnyObject] {
                print("jsonData Successfully Sent data: \n\(jsonDataDict))")
            }
        }
    } catch let err as NSError {
        print("jsonData Error: \(err.debugDescription)")
    }
}
task.resume()
