我想从BOX.COM的oauth2检索访问令牌，无论我做什么，我得到了同样的错误。 {错误：INVALID_REQUEST，ERROR_DESCRIPTION：无效的grant_type参数或参数丢失}。我已经验证了客户端ID，客户端秘密，每次我试图（每30秒到期），得到一个新的code。
我曾尝试VB.NET，C＃，甚至RESTClient实现插件Firefox浏览器。下面是VB.NET code，我使用。任何帮助将大大AP preciated！

您可能还需要添加以下，以确保您使用XML编码。

  request.Method = Method.POST
request.RequestFormat = DataFormat.Xml
 

I am trying to retrieve an Access Token from BOX.COM oauth2 and no matter what I do I get the same error. {"error":"invalid_request","error_description":"Invalid grant_type parameter or parameter missing"}. I have verified the client id, client secret and get a new code every time I try (the expire every 30 seconds). I have tried VB.NET, C# and even the RestClient plugin for FireFox. Below is the VB.NET code that I am using. Any help would be greatly appreciated! Thanks, Brian

Public Sub GetAccessToken(ByVal code As String, ByVal client_id As String, ByVal client_secret As String)
        Dim xrc As RestClient = New RestClient
        Dim grant_type As String = "authorization_code"
        Dim request As New RestRequest(Method.POST)
        Dim strHeaders As String
        Dim response As RestResponse
        Dim strResponse As String


        Try
            'Base URL
            xrc.BaseUrl = "https://api.box.com"

            'Resource
            request.Resource = "oauth2/token"

            'Format Headers
            strHeaders = String.Format("grant_type={0}&code={1}&client_id={2}&client_secret={3}", grant_type, code, client_id, client_secret)

            'Add Headers to request
            request.AddHeader("Authorization", strHeaders)

            'Execute
            response = xrc.Execute(request)

            'Parse Response
            strResponse = response.Content

        Catch ex As Exception

        End Try

    End Sub 

解决方案

You may also need to add the following to ensure you're using xml encoding.

request.Method = Method.POST
request.RequestFormat = DataFormat.Xml
