ios - alamofire swift3 的失败响应

Question

你好，我被 alamofire 困住了。

    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)")

这是打印的参数

dict theParams: ["contacts": <Swift._SwiftDeferredNSArray 0x604000233280>(
{
    "contact_id" = 0;
    "full_name" = Kate;
    "mobile_number" = "62123123";
},
{
    "contact_id" = 1;
    "full_name" = Daniel;
    "mobile_number" = "621231123";
},
{
    "contact_id" = 2;
    "full_name" = John;
    "mobile_number" = "625435345";
}
)
]

我使用此代码将其发送到 alamofire

func sendFriendList(dictContacts: [String:AnyObject] ,successBlock:((_ isSuccess: Bool, _ theFriendsResponse: FriendsResponse)->Void)?,errorBlock:((_ errorString:String)->Void)? )-> Void
    {

Alamofire.request("url/ListRetrieve",
        method: .post,
        parameters: dictContacts,
        encoding: URLEncoding.default,
        headers: headers)
        .responseJSON { response in
            print("this is response retrieve \(response)")

以及 alamofire 的响应:

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.}))

但是如果我只更改参数，就像这样[“联系人”:“测试联系人”]

alamofire 的响应取得了成功，并且成功了。

请帮助我:)谢谢

这不是 Alamofire 问题。 API 需要 String 形式的“contacts”参数，并且您要发送 Dictionaries 的 Array。如果您要在“contacts”参数中发送 Array 数据，请要求 api 开发人员更改参数类型，或者如果可能，将字符串作为“contacts”参数中的数据发送。

问题:

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.}))

也仅说明无效字符。
