問題描述
我無法從 MVC 應用程序訪問特定的 Google Drive 帳戶.我所需要的只是讓 MVC Web 應用程序訪問我的谷歌驅動器掃描幾個文件并根據谷歌驅動器的內容更改數據庫.問題是在 IIS 中運行時，驅動器無法通過身份驗證，因為如果 GoogleWebAuthorizationBroker 嘗試打開瀏覽器(如果它是 Windows 應用程序)但似乎無法通過 IIS 執行此操作，即使它是服務器端的.
I'm stuck trying to access a specific Google drive account from a MVC app. All I need is for the MVC web app to access my google drive scan for a few files and alter the database based on the contents of the google drive. The problem is when running in IIS the drive cannot be authenticated as GoogleWebAuthorizationBroker tries to open browser if its a windows app but doesn't seem to be able to do that through IIS and even if it did it would be server side.
理想情況下，我根本不需要對這個應用程序進行身份驗證，但如果它確實通過了驗證，那么我該如何讓它在 IIS 中工作?
Ideally I would not have to authenticate this app at all, but if it has do go through that then how do I make it work in IIS?
UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
new ClientSecrets
{
ClientId = "MY_ID",
ClientSecret = "My_Secret"
},
new[] { DriveService.Scope.Drive },
"user",
CancellationToken.None, dataStore: new FileDataStore(Server.MapPath("~/app_data/googledata"))).Result;
推薦答案
我得到了這個工作，能夠使網站使用我的帳戶訪問 Google 驅動器，而無需要求用戶登錄或授權.
I got this to work, was able to enable the web site to access Google drive using my account without asking users to login or authorize.
首先，點擊此鏈接讓 Google API 與 MVC 一起工作:
First of all, follow this link to get Google API work with MVC:
https://developers.google.com/api-client-library/dotnet/guide/aaa_oauth#web_applications
示例代碼中存在問題，在 HomeController 中
There is a problem in the Sample code, in HomeController
public async Task IndexAsync(CancellationToken cancellationToken)
應該是:
public async Task<ActionResult> IndexAsync(CancellationToken cancellationToken)
之后，我創建了一個 MemoryDataStore(參見最后的代碼)，它是對此處發布的 MemoryDataStore 的輕微修改:
After that, I created a MemoryDataStore (see code at the end) that is a slightly modification from the MemoryDataStore posted here:
http://conficient.wordpress.com/2014/06/18/using-google-drive-api-with-c-part-2/
完成此操作后，捕獲您正在使用的帳戶的刷新令牌，并在驗證時將存儲替換為此存儲:
Once you do that, capture the refresh token of the account you are using, and replace the store with this store when authenticate:
private static readonly IAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = clientID,
ClientSecret = clientSecret
},
Scopes = new[] { DriveService.Scope.Drive },
//DataStore = new FileDataStore("Drive.Api.Auth.Store")
DataStore = new GDriveMemoryDataStore(commonUser, refreshToken)
});
這里的 commonUser 是您選擇的預定義用戶 ID.請務必修改 GetUserID() 方法以返回相同的 commonUser:
Here commonUser is a predefined user id of your chosen. Please make sure to modify the GetUserID() method to return the same commonUser:
public override string GetUserId(Controller controller)
{
return commonUser;
}
完成此操作后，Google Drive 將停止要求用戶登錄和授權應用程序.
Once this is done, Google drive will stop asking user to login and authorize the app.
這是我的 MemoryDataStore 代碼:
Here is my MemoryDataStore code:
/// <summary>
/// Handles internal token storage, bypassing filesystem
/// </summary>
internal class GDriveMemoryDataStore : IDataStore
{
private Dictionary<string, TokenResponse> _store;
private Dictionary<string, string> _stringStore;
//private key password: notasecret
public GDriveMemoryDataStore()
{
_store = new Dictionary<string, TokenResponse>();
_stringStore = new Dictionary<string, string>();
}
public GDriveMemoryDataStore(string key, string refreshToken)
{
if (string.IsNullOrEmpty(key))
throw new ArgumentNullException("key");
if (string.IsNullOrEmpty(refreshToken))
throw new ArgumentNullException("refreshToken");
_store = new Dictionary<string, TokenResponse>();
// add new entry
StoreAsync<TokenResponse>(key,
new TokenResponse() { RefreshToken = refreshToken, TokenType = "Bearer" }).Wait();
}
/// <summary>
/// Remove all items
/// </summary>
/// <returns></returns>
public async Task ClearAsync()
{
await Task.Run(() =>
{
_store.Clear();
_stringStore.Clear();
});
}
/// <summary>
/// Remove single entry
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="key"></param>
/// <returns></returns>
public async Task DeleteAsync<T>(string key)
{
await Task.Run(() =>
{
// check type
AssertCorrectType<T>();
if (typeof(T) == typeof(string))
{
if (_stringStore.ContainsKey(key))
_stringStore.Remove(key);
}
else if (_store.ContainsKey(key))
{
_store.Remove(key);
}
});
}
/// <summary>
/// Obtain object
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="key"></param>
/// <returns></returns>
public async Task<T> GetAsync<T>(string key)
{
// check type
AssertCorrectType<T>();
if (typeof(T) == typeof(string))
{
if (_stringStore.ContainsKey(key))
return await Task.Run(() => { return (T)(object)_stringStore[key]; });
}
else if (_store.ContainsKey(key))
{
return await Task.Run(() => { return (T)(object)_store[key]; });
}
// key not found
return default(T);
}
/// <summary>
/// Add/update value for key/value
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="key"></param>
/// <param name="value"></param>
/// <returns></returns>
public Task StoreAsync<T>(string key, T value)
{
return Task.Run(() =>
{
if (typeof(T) == typeof(string))
{
if (_stringStore.ContainsKey(key))
_stringStore[key] = (string)(object)value;
else
_stringStore.Add(key, (string)(object)value);
} else
{
if (_store.ContainsKey(key))
_store[key] = (TokenResponse)(object)value;
else
_store.Add(key, (TokenResponse)(object)value);
}
});
}
/// <summary>
/// Validate we can store this type
/// </summary>
/// <typeparam name="T"></typeparam>
private void AssertCorrectType<T>()
{
if (typeof(T) != typeof(TokenResponse) && typeof(T) != typeof(string))
throw new NotImplementedException(typeof(T).ToString());
}
}
