目前正在使用outlook v2.0,这对我来说真的很新,我遇到了一个无法预料的问题。目前我有我的身份验证,并且能够在没有问题的情况下创建我的Outlook客户端。但是,在目前有250封电子邮件的邮箱上进行测试运行之后,我发现这个api只检索了10个。在使用Outlook api v 2.0时查看是否有人遇到过这个问题
代码
private static async Task<OutlookServicesClient> CreateOutlookClientAsync(AuthenticationContext authenticationContext)
{
OutlookServicesClient outlookClient = null;
try
{
outlookClient = new OutlookServicesClient(
new Uri(CrmPrototype.Helpers.AuthHelper.OutlookAPIEndpoint),
async () =>
await GetTokenHelperAsync(authenticationContext, CrmPrototype.Helpers.AuthHelper.OutlookAuthenticationEndpoint)
);
return outlookClient;
}
catch (Exception ex)
{
// TODO Log
return outlookClient;
}
}
private static async Task<GraphServiceClient> CreateGraphClientAsync(AuthenticationContext authenticationContext)
{
GraphServiceClient graphClient = null;
try
{
graphClient = new GraphServiceClient(
new DelegateAuthenticationProvider(
async (requestMessage) =>
{
string accessToken = await GetTokenHelperAsync(authenticationContext, CrmPrototype.Helpers.AuthHelper.OutlookAuthenticationEndpoint);
// Append the access token to the request.
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
}));
return graphClient;
}
catch (Exception ex)
{
// TODO Log
return graphClient;
}
}
private static async Task<string> GetTokenHelperAsync(AuthenticationContext context, string resourceId)
{
string accessToken = null;
try
{
X509Certificate2 certificate = new X509Certificate2(CrmPrototype.Helpers.AuthHelper.devCertPath, CrmPrototype.Helpers.AuthHelper.devCertKey, X509KeyStorageFlags.MachineKeySet);
ClientAssertionCertificate clientAssertionCert = new ClientAssertionCertificate(CrmPrototype.Helpers.AuthHelper.devClientId, certificate);
AuthenticationResult result = null;
result = await context.AcquireTokenAsync(resourceId, clientAssertionCert);
accessToken = result.AccessToken;
return accessToken;
}
catch (Exception ex)
{
// TODO Log
return accessToken;
}
}
public static async Task<IMessageCollection> GetEmails(string emailBox)
{
IMessageCollection emails = null;
AuthenticationContext authenticationContext = new AuthenticationContext(CrmPrototype.Helpers.AuthHelper.devTenant);
try
{
var outlookClient = await CreateOutlookClientAsync(authenticationContext);
var mail_Box = await outlookClient.Users[emailBox].MailFolders["Inbox"].Messages.OrderByDescending(m => m.ReceivedDateTime).ExecuteAsync();
var messages = mail_Box.CurrentPage; << only gets 10 emails at a time
foreach (var message in messages)
{
var stop = 0;
}
return emails;
}
catch (Exception ex)
{
// TODO Log
return emails;
}
}

名称表示的OutlookREST API是REST API。您正在使用SDK代表您伪造http Web请求。就个人而言,即使我使用C#,我也会手动伪造请求。即使使用SDK,我的建议是你需要查看生成的实际请求并发送到托管api的服务器。我建议你使用像fiddler这样的工具。
话虽如此,$top
ODATA参数的默认参数设置为10.这就是为什么你有10个项目,但不要担心你可以通过调用下一个分页来获取它们。您可以在_continuation
成员中看到实际的续订网址。请注意值$top
和$skip
参数:这意味着对于此请求,您将获取另外10个项目,跳过10个第一项。
通常,您无法通过一次调用从无限制的来源中获取所有项目。你需要一个分页机制。但是,您可以通过更改$top
参数的值来增加页面大小。使用.NET SDK,this page看起来应该使用LINQ中的Take
方法。
