alamofire.error Code = -6006"JSON无法序列化

Question

一直在研究这个没有成功.我有一个函数,UIButton仅用于执行对使用所有JSON的rails api的alamofire调用.

我正在使用Swift 2,Alamofire 3,XCode 7和Rails 4为我的api部署到Heroku

当我关闭该功能时,我不断收到此错误:

alamofire.error Code = -6006"JSON无法序列化.输入数据为零或零长度.

这是我的代码:

@IBAction func Save(sender: AnyObject) {

    let postsEndpoint: String = "https://APIURL"
    let parameters = [
        "users": [
            "name": "James McHarty",
            "avatar": "Some binary data",
            "post": [
                "title": "First Test Post",
                "body": "This is the first test post for the API",
                "liked": "8", //will make INT later
                "img": "more binary data"
            ]
        ]
    ]

    Alamofire.request(.POST, postsEndpoint, parameters: parameters, encoding: .JSON)
        .responseJSON { response in
            guard response.result.error == nil else {
            // got an error in getting the data, need to handle it
            print(response.result.error!)
            return
        }

    }

    print("func'd")

}

这不是Alamofire错误或迅速错误，服务器返回的响应不是JSON格式。您可以打印出响应数据并检查其中有什么问题。

尝试使用此代码打印出我们的服务器数据，以轻松识别错误并解决。

Alamofire.request("Your url").responseJSON(completionHandler: { (response) in
    switch response.result {
    case .success(let value):
        break

    case .failure(let error):
        print("\n\n===========Error===========")
        print("Error Code: \(error._code)")
        print("Error Messsage: \(error.localizedDescription)")
        if let data = response.data, let str = String(data: data, encoding: String.Encoding.utf8){
            print("Server Error: " + str)
        }
        debugPrint(error as Any)
        print("===========================\n\n")
    }

})
