Ios alamofire swift3的故障响应

你好，我被阿拉莫菲尔绊倒了

    let keys = [CNContactPhoneNumbersKey, CNContactGivenNameKey]
    let request = CNContactFetchRequest(keysToFetch: keys as [CNKeyDescriptor])
    let contactStore = CNContactStore()
    do {
        try contactStore.enumerateContacts(with: request) {
            (contact, stop) in
            // Array containing all unified contacts from everywhere
            self.contacts.append(contact)
        }
    }
    catch {
        print("unable to fetch contacts")
    }
    var contactArray = [[String:String]]()

    for i in 0..<contacts.count{
        var mobiles = ""
        for num in contacts[i].phoneNumbers {

            mobiles = num.value.stringValue
        }



        var theDict = ["contact_id": "\(i)", "full_name": contacts[i].givenName, "mobile_number": "\(mobiles)"]
        contactArray.append(theDict)

    }

    dictParams["contacts"] = dictContacts



    let theParams = ["contacts":contactArray] as [String:AnyObject]
    print("dict theParams: \(theParams)")

阿拉莫菲尔的回应是：

this is the response = retrieve FAILURE: responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 1." UserInfo={NSDebugDescription=Invalid value around character 1.}))

但是如果我改变参数，只有这样的字符串 [“联系人”：“测试联系人”]

阿拉莫菲尔反应成功了，它的工作

请帮助我：）谢谢

使用

responseString

而不是

responseJSON

。然后使用

JSONSerialization

将响应转换为JSON
比如：

JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]  


func convertToDictionary(text: String) -> [String: Any]? {
    if let data = text.data(using: .utf8) {
        do {
            return try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
        } catch {
            print(error.localizedDescription)
        }
    }
    return nil
}

这不是阿拉莫菲尔的问题。api需要“contacts”参数作为

String

，并且您正在发送

字典的
数组。如果要在“contacts”参数中发送
数组
数据，请让api开发人员更改参数类型，或在可能的情况下将字符串作为“contacts”参数中的数据发送

问题是：

这是response=retrieve FAILURE:responseSerializationFailed（Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed（错误域=NSCOCAerorDomain代码=3840“字符1周围的无效值”。“用户信息={NSDebugDescription=字符1周围的无效值”。）

也仅声明无效字符。
我的参数如下

// .toJson to your array object or dictonary object and try out
let parameters: [String : Any] = [
    "products":[
         ["pid":"72","qnty":"1"],
         ["pid":"4","qnty":"1"],
         ["pid":"3","qnty":"1"]
     ].toJson ?? "[]",   
]

使用此扩展将数组对象转换为JSON字符串

extension Array where Element: Codable {

    public var toData: Data {
        let encoder = JSONEncoder()
        do {
            return try encoder.encode(self)
        }
        catch {
            fatalError(error.localizedDescription)
        }
    }

    public var toJson: String? {
        return toData.toJson
    }
}

如何将responseString转换为responseJSON？我已经在使用responseString，并且响应成功。我应该将什么转换为dictionary？答复。？
// .toJson to your array object or dictonary object and try out
let parameters: [String : Any] = [
    "products":[
         ["pid":"72","qnty":"1"],
         ["pid":"4","qnty":"1"],
         ["pid":"3","qnty":"1"]
     ].toJson ?? "[]",   
]

extension Array where Element: Codable {

    public var toData: Data {
        let encoder = JSONEncoder()
        do {
            return try encoder.encode(self)
        }
        catch {
            fatalError(error.localizedDescription)
        }
    }

    public var toJson: String? {
        return toData.toJson
    }
}
