我收到了authorization code
,想要将其与服务器上的authorization token
交换。 .NET API API在流类中有ExchangeCodeForTokenAsync
方法。看起来像我需要但它需要userId作为其参数之一。
var flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = "...",
ClientSecret = "..."
},
Scopes = new[] { "some scopes" },
});
flow.ExchangeCodeForTokenAsync(userId, code, "redirect url", CancellationToken.None); //exchange token requires userId
我应该在收到授权令牌之前注册用户吗?但在我获取他的Google个人资料信息之前我无法做到(我需要一个令牌)。
不幸的是,没有.NET客户端的文档,但documentation for other languages(搜索"在Web服务器收到授权代码后#34;在页面上访问相关部分)不提userId。
所以要么我试图使用错误的方法,要么.NET Api是错误的,或者我只是错过了一些明显的东西。

让我们从获取用户的个人资料信息开始。
您可以为此People API和Google + API使用两种API。
以下方法将请求用户访问。通过发送不同的用户名来更改每个用户,然后将凭据信息存储在%appData%中,您可以阅读有关此here的更多信息
/// <summary>
/// This method requests Authentcation from a user using Oauth2.
/// Credentials are stored in System.Environment.SpecialFolder.Personal
/// Documentation https://developers.google.com/accounts/docs/OAuth2
/// </summary>
/// <param name="clientSecretJson">Path to the client secret json file from Google Developers console.</param>
/// <param name="userName">Identifying string for the user who is being authentcated.</param>
/// <returns>DriveService used to make requests against the Drive API</returns>
public static PeopleService AuthenticateOauth(string clientSecretJson, string userName)
{
try
{
if (string.IsNullOrEmpty(userName))
throw new ArgumentNullException("userName");
if (string.IsNullOrEmpty(clientSecretJson))
throw new ArgumentNullException("clientSecretJson");
if (!File.Exists(clientSecretJson))
throw new Exception("clientSecretJson file does not exist.");
// These are the scopes of permissions you need. It is best to request only what you need and not all of them
string[] scopes = new string[] { PeopleService.Scope.UserPhonenumbersRead, //View your phone numbers
PeopleService.Scope.UserAddressesRead, //View your street addresses
PeopleService.Scope.UserBirthdayRead, //View your complete date of birth
PeopleService.Scope.ContactsReadonly, //View your contacts
PeopleService.Scope.UserEmailsRead, //View your email addresses
PeopleService.Scope.UserinfoProfile, //View your basic profile info
PeopleService.Scope.UserinfoEmail, //View your email address
PeopleService.Scope.PlusLogin, //Know your basic profile info and list of people in your circles.
PeopleService.Scope.Contacts}; //Manage your contacts
UserCredential credential;
using (var stream = new FileStream(clientSecretJson, FileMode.Open, FileAccess.Read))
{
string credPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
credPath = Path.Combine(credPath, ".credentials/", System.Reflection.Assembly.GetExecutingAssembly().GetName().Name);
// Requesting Authentication or loading previously stored authentication for userName
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(GoogleClientSecrets.Load(stream).Secrets,
scopes,
userName,
CancellationToken.None,
new FileDataStore(credPath, true)).Result;
}
// Create Drive API service.
return new PeopleService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "People Oauth2 Authentication Sample"
});
}
catch (Exception ex)
{
Console.WriteLine("Create Oauth2 account PeopleService failed" + ex.Message);
throw new Exception("CreateServiceAccountPeopleFailed", ex);
}
}
这将返回一个PeopleService,您可以使用它来向人们api发出请求。就像向用户请求数据一样。
var me = service.People.Get(&#34; people / me&#34;)。执行();
您可以将谷歌日历范围添加到其中,您的用户指南将有利于谷歌人员服务和谷歌日历服务。
我也有一些谷歌日历here的示例代码。
更新javascript问题:
JavaScript不包含只有访问令牌的刷新令牌。 FileDatastore无法理解这一点。您可能需要自己实现idatastore。我的问题是你打算如何处理访问令牌到期时你是否要回复你的JavaScript授权代码?

我浏览了AuthorizationCodeFlow source code,虽然userId未用于Google Api请求(如预期的那样),但它用于将结果存储到DataStore。因此,如果您只是使用api调用结果,则可能无法传递userId,否则您必须拥有它。
答案 2 :(得分:0)
要通过access_token交换授权码,您需要from the docs
也许您说的是期望userId
是client_id
...我不知道图书馆...如果说假设有一个userId而不是client_id,则可能是一个错误这个ExchangeCodeForTokenAsync
方法。
