Dropbox JSON反序列化器似乎使用了错误的对象类型

本文关键字：错误 对象 类型 反序列化 JSON Dropbox | 更新日期: 2023-09-27 18:04:03

我正在使用DropNetRT尝试与Dropbox集成，但在从Dropbox API反序列化JSON响应时始终得到错误。废话少说:

抛出的异常是 
Newtonsoft.Json.JsonReaderException occurred
  HResult=-2146233088
  Message=Error reading string. Unexpected token: StartObject. Path 'entries[0][1]', line 1, position 202.
  Source=Newtonsoft.Json
  LineNumber=1
  LinePosition=202
  Path=entries[0][1]

在var deltaResponse = JsonConvert.DeserializeObject<DeltaPageInternal>(responseBody);

上抛出异常

responseBody是什么?是这个家伙(为了方便大家，稍微简化了一下)

{   
    "has_more": true, 
    "cursor": "BLAGHABLAGAbigDarn-StringTHing123", 
    "entries": 
    [
        ["/exampleFile.pdf", {"revision": 1, "rev": "1131aa664", "thumb_exists": false, "bytes": 249159, "modified": "Mon, 12 Aug 2013 18:55:30 +0000", "client_mtime": "Mon, 12 Aug 2013 18:55:30 +0000", "path": '"/exampleFole.pdf'", "is_dir": false, "icon": "page_white_acrobat", "root": "dropbox", "mime_type": "application/pdf", "size": "243.3 KB"}],
        ["/examplefolder", {"revision": 2, "rev": "2131aa664", "thumb_exists": false, "bytes": 0, "modified": "Tue, 13 Aug 2013 17:30:35 +0000", "path": "/examplefolder", "is_dir": true, "icon": "folder_user", "root": "dropbox", "size": "0 bytes"}]
    ], 
    "reset": true
}

我怀疑模型DeltaPageInternal是罪魁祸首，因为条目[0][1]实际上并不是模型所暗示的:

internal class DeltaPageInternal
{
    public string Cursor { get; set; }
    public bool Has_More { get; set; }
    public bool Reset { get; set; }
    public List<List<string>> Entries { get; set; }
}

还有人有这个问题吗?从Dropbox收到的反馈来看，这似乎应该是相当普遍的……我调用的是旧版本的API吗?

像往常一样，提前感谢你的专业知识。

把你的字符串改成这个，这不是一个有效的json字符串http://json.parser.online.fr/
