Box.Net 创建文件夹错误请求 400

Question

Dim url As String = String.Format("{0}folders/{1}", boxApiUrl, ParentFolderId)  'ParentFolderId being pass is "0"
    Using request = New HttpRequestMessage() With {.RequestUri = New Uri(url), .Method = HttpMethod.Post}
        request.Headers.Authorization = New System.Net.Http.Headers.AuthenticationHeaderValue("Authorization", "Bearer " + acctoken)

       Dim data As Dictionary(Of [String], [String]) = New Dictionary(Of String, String)()
       data.Add("name", FolderName)

       Dim content As HttpContent = New FormUrlEncodedContent(data)
       request.Content = content
       Dim response = _httpClient.SendAsync(request).Result
       If response.IsSuccessStatusCode Then
                '        
       End If
    End Using

我怀疑数据没有正确地放在一起，但无法弄清楚如何传递要在根目录下创建的文件夹名称。使用令牌的所有其他功能（读取根文件夹、上传文件等）都可以正常工作。

父文件夹 ID 在 POST 正文中传递，而不是 URL。主体应该是 JSON 形式的数据：{ "name": "FolderName", "parent": { "id": "ParentFolderId" }}。 Documentation.

Dim url As String = String.Format("{0}folders", boxApiUrl)
Using request = New HttpRequestMessage() With {.RequestUri = New Uri(url), .Method = HttpMethod.Post}
    request.Headers.Authorization = New System.Net.Http.Headers.AuthenticationHeaderValue("Authorization", "Bearer " + acctoken)

   Dim format as String = @"{{ ""name"":""{0}"", ""parent"": {{ ""id"":""{1}"" }} }}";
   Dim body as String = String.Format(format, FolderName, ParentFolderId);
   request.Content = New StringContent(body, Encoding.UTF8, "application/json")

   Dim response = _httpClient.SendAsync(request).Result
   If response.IsSuccessStatusCode Then
            '        
   End If
End Using

另外，您可以使用 Json.NET 的 JsonConvert.SerializeObject 方法将匿名或静态类型序列化为 JSON 字符串：

Dim obj = New With {Key .name = FolderName, 
                        .parent = New With {Key .id = ParentFolderId }};
Dim body as String = JsonConvert.SerializeObject(body);
request.Content = New StringContent(body, Encoding.UTF8, "application/json")
