Office365 REST API使用C＃ADAL返回Unauthorized

Question

我正在構建一個WPF-App。 首先獲取事件，然后通過O365 RestAPI創建事件。

我能夠通過以下方式獲得活動：

result = await authContext.AcquireTokenAsync(graphResourceId, clientId, redirectUri, new PlatformParameters(PromptBehavior.Auto));Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE");
                    string today = DateTime.Today.ToString("yyyy-MM-dd", CultureInfo.CurrentCulture);
                    string graphRequest = String.Format(CultureInfo.CurrentCulture, "https://outlook.office365.com/api/v2.0/me/calendarview?startDateTime=" + today + "T00:00:00&endDateTime=" + today + "T23:59:00&$select=Subject,organizer,start,end,attendees&$orderby=start/datetime%20asc");
                    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, graphRequest);
                    request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
                    request.Headers.Add("Prefer", "outlook.timezone=\"W. Europe Standard Time\"");
                    HttpResponseMessage response = HttpClient.SendAsync(request).Result;

                    if (!response.IsSuccessStatusCode)
                        throw new WebException(response.StatusCode.ToString() + ": " + response.ReasonPhrase);

但是當我嘗試創建事件時，我將使用相同的令牌收到“未授權”。 我的應用程序有權讀取和寫入日歷。

這是我的代碼：

string postBody = "{'Subject':" + "'Discuss the Calendar REST API'," +
                            "'Body':{ " +
                                          "'ContentType':'HTML'," +
                              "'Content': 'I think it will meet our requirements!'},"
                           + "'Start': { DateTime: '" + 
                              start + "',"
                                    + " 'TimeZone': 'W. Europe Standard Time'}," +
                               "'End':{'DateTime': '" + end + "'," +
                                    "'TimeZone': 'W. Europe Standard Time'},"
                                + "'Attendees':[{" +
                                "'EmailAddress':{"
                                 + "'Address': '" + MailTB.Text + "'"
                                + 
                                " },"
                                + "'Type': 'Required'}]}";


    var emailBody = new StringContent(postBody, System.Text.Encoding.UTF8, "application/json");
        AuthenticationContext authContext = new AuthenticationContext(authority, new FileCache());
        AuthenticationResult result = await authContext.AcquireTokenAsync(graphResourceId, clientId, redirectUri, new PlatformParameters(PromptBehavior.Auto));

        Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE");
    string today = DateTime.Today.ToString("yyyy-MM-dd", CultureInfo.CurrentCulture);
    string graphRequest = String.Format(CultureInfo.CurrentCulture, "https://outlook.office365.com/api/v2.0/me/events");
    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, graphRequest);
    request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
    request.Headers.Add("Prefer", "outlook.timezone=\"W. Europe Standard Time\"");
        HttpResponseMessage response = MainWindow.HttpClient.PostAsync(graphRequest, emailBody).Result;

        if (!response.IsSuccessStatusCode)
            throw new WebException(response.StatusCode.ToString() + ": " + response.ReasonPhrase);

Answer 1

HttpRequestMessage request = new HttpRequestMessage（HttpMethod.Post，graphRequest）; request.Headers.Authorization = new AuthenticationHeaderValue（“Bearer”，result.AccessToken）; request.Headers.Add（“Prefer”，“outlook.timezone = \\”W。Europe Standard Time \\“”）; HttpResponseMessage響應= MainWindow.HttpClient.PostAsync（graphRequest，emailBody）.Result;

您發送帖子請求的代碼將不會發送您設置的標題，因為所有標題都是為request參數設置的，但您沒有在帖子中使用它。

要使用access_token發送帖子，您可以參考以下代碼：

var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Authorization= new AuthenticationHeaderValue("Bearer", accessToken);
httpClient.DefaultRequestHeaders.Add("Prefer", "outlook.timezone=\"W. Europe Standard Time\"");
HttpResponseMessage response = httpClient.PostAsync(graphRequest, emailBody).Result;
