词典中的错误 [英] geting error with Dictionary

问题描述

     let parameter : Dictionary<String,AnyObject> =  ["action":"add-playlist-item","playlist_id":self.dictPlayList.objectForKey("ID")!,"kod_id":arrayOfID]

错误
[action：add-playlist-item，playlist_id：166，kod_id：< _TtCs21_SwiftDeferredNSArray 0x7c615620>（
21，
18
）
]

error ["action": add-playlist-item, "playlist_id": 166, "kod_id": <_TtCs21_SwiftDeferredNSArray 0x7c615620>( 21, 18 ) ]

_TtCs21_SwiftDeferredNSArray 0x7c615620这个错误是什么意思？

_TtCs21_SwiftDeferredNSArray 0x7c615620 what does this error mean??

推荐答案

检查您是否使用JSON参数编码，而不是URL编码。

Check that you are using JSON parameter encoding, not URL encoding.

您可能遇到了同样的问题。我看到< _TtCs21_SwiftDeferredNSArray 0x7c615620> 也出现在我的请求中。当我更改为JSON编码时，一切正常。我不认为这样的字典结构可以被正确的URL编码。我不知道你是如何实际提出请求的，或者我会发布代码。

You may be having the same problem I was having. I was seeing <_TtCs21_SwiftDeferredNSArray 0x7c615620> appear in my requests too. When I changed to JSON encoding, everything worked. I don't think a dictionary structure like that can be properly URL encoded. I'm not sure how you're actually making the request or I would post code.
