我有一个将文件上传到 Box 的 C# 桌面应用程序，
它需要一个刷新令牌来生成访问令牌，但我无法以编程方式创建刷新令牌。从This site 创建刷新令牌并成功将文件上传到 Box，但此刷新令牌在几分钟后过期并引发异常Refresh token has expired。我正在使用box-csharp-sdk-v2。
所以我想使用我的客户端详细信息或 api 密钥以编程方式创建一个刷新令牌

为了使用 Box OAuth2 令牌，您需要使用您的应用程序的 API 密钥和密钥来实例化 TokenProvider：
// Instantiate a token provider.
var tokenProvider = new TokenProvider("apiKey", "apiSecret");
通过 OAuth2 工作流程发送用户后，您将收到授权 code。 TokenProvider 可以使用这个code 来获取第一个访问/刷新令牌对：
// Fetch the initial access/refresh token pair
// You will want to persist these new values for later use.
var initialTokenPair = tokenProvider.GetAccessToken("code")
每次刷新Access 令牌时，都会为您提供一个新的Refresh 令牌。 Refresh 令牌在使用时或大约 60 天后过期，以先到者为准。
// Refresh the token pair.
// You will want to persist these new values for later use.
var newTokenPair = tokenProvider.RefreshAccessToken("refreshToken");
我用上面的例子更新了 box-csharp-sdk-v2 readme。很抱歉之前没有说清楚！
编辑：添加了获取初始令牌对的示例。

code 获取初始令牌对的示例。
使用此代码
/*******************/
/** Authorization **/
/*******************/
// Create a OAuth2 access/refresh token provider using your API key/secret.
var tokenProvider = new TokenProvider("apiKey", "apiSecret");
// Fetch the initial token pair using the OAuth2 authorization code...
// You will want to persist these new values for later use.
var initialTokenPair = tokenProvider.GetAccessToken("code");
// You can also refresh the token pair.
// You will want to persist these new values for later use.
var newTokenPair = tokenProvider.RefreshAccessToken("refreshToken");
/*********************/
/** Box Interaction **/
/*********************/
// Instantiate a BoxManager client.
var boxManager = new BoxManager(newTokenPair.AccessToken);
// Create a new file in the root folder
boxManager.CreateFile(Folder.Root, "a new file.txt", Encoding.UTF8.GetBytes("hello, world!"));
// Fetch the root folder
var folder = boxManager.GetFolder(Folder.Root);
// Find a 'mini' representation of the created file among the root folder's contents
var file = folder.Files.Single(f => f.Name.Equals("a new file.txt"));
// Get the file with all properties populated.
file = boxManager.Get(file);
// Rename the file
file = boxManager.Rename(file, "the new name.txt");
// Create a new subfolder
var subfolder = boxManager.CreateFolder(Folder.Root, "my subfolder");
// Move the file to the subfolder
file = boxManager.Move(file, subfolder);
// Write some content to the file
using (var stream = new MemoryStream(Encoding.UTF8.GetBytes("goodbye, world!")))
{
file = boxManager.Write(file, stream);
}
// Read the contents to a stream and write them to the console
using (var stream = new MemoryStream())
{
boxManager.Read(file, stream);
using (var reader = new StreamReader(stream))
{
stream.Position = 0;
Console.Out.WriteLine("File content: '{0}'", reader.ReadToEnd());
}
}
// Delete the folder and its contents
boxManager.Delete(subfolder, recursive: true);
As an enterprise administrator you can create a client and perform Box operations on behalf of another user.
// Instantiate a BoxManager client.
var boxManager = new BoxManager("AccessToken", onBehalfOf: "user@domain.com");
// ... do stuff as that user
// ... use your power only for awesome!
