他们写道:“支持的平台:可移植类库”。
但是后来我在可移植类中编写了这段代码,出现一个错误:
public async void MyFuncrion()
{
UserCredential credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
//new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read),
new ClientSecrets
{
ClientId = "", //"PUT_CLIENT_ID_HERE",
ClientSecret = "" //"PUT_CLIENT_SECRETS_HERE"
},
new[] { TasksService.Scope.Tasks },
"user",
CancellationToken.None);
var service = new TasksService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "Tasks API Sample",
});
TaskLists results = await service.Tasklists.List().ExecuteAsync();
foreach (var tasklist in results.Items)
{
TasklistTitlesCollection.Add(tasklist.Title + " " + tasklist.Updated);
// You can get data from the file (using file.Title for example)
// and append it to a TextBox, List, etc.
}
}
此处错误:“
UserCredential credential = await GoogleWebAuthorizationBroker.AuthorizeAsync()
”,他不在可移植库中工作。如何使用库,获取没有GoogleWebAuthorizationBroker
的任务。我已经自己获取访问令牌,只需要TasksService
,也许我可以在构造函数TasksService
中越过访问令牌和其他令牌? 最佳答案
我用这篇文章来打破这堵墙google .net library
在这里,我通过PCL和Windows8传递了一些代码。
PCL:
您需要提供数据存储
private async Task<GoogleAuthorizationCodeFlow.Initializer> InitInitializer()
{
_iDataStore = await _userCredential.GetDataStore(); //new StorageDataStore()
var initializer = new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = ClientId, //"PUT_CLIENT_ID_HERE",
ClientSecret = ClientSecret, //"PUT_CLIENT_SECRET_HERE"
},
Scopes = new[] { TasksService.Scope.Tasks },
DataStore = (Google.Apis.Util.Store.IDataStore)_iDataStore //new StorageDataStore()
};
return initializer;
}
然后
public async Task<TasksService> Prepare()
{
GoogleAuthorizationCodeFlow.Initializer initializer = await InitInitializer();
Object credential = new Object();
if (String.IsNullOrEmpty(_username))
{
return null;
}
TasksService service = null;
try
{
credential = await _userCredential.GetCredential(initializer, _username);
}
catch (Google.Apis.Auth.OAuth2.Responses.TokenResponseException e)
{
service = null;
return service;
}
catch
{
return null;
}
service = new TasksService(new BaseClientService.Initializer
{
HttpClientInitializer = (UserCredential)credential,
ApplicationName = _applicationName,
});
return service;
}
1)在Windows应用商店中,您需要提供StorageDataStore并将其遍历到pcl。
2)使用
AuthorizationCodeWinRTInstalledApp(initializer).AuthorizeAsync(username, new CancellationToken(false))
从Google图书馆(Google.Apis.Auth.OAuth2)获取证书并将其遍历到pcl
