我们使用 SharePoint 客户端对象模型为 SharePoint online 构建 Windows 客户端应用程序。我们想使用OAuth 来对这个Windows 客户端应用程序进行身份验证,但是我们没有找到实现它的方法;并且 MSDN 上的文档含糊不清。

article然而,举了一个例子,当我使用链接创建新应用程序时 https://<TENANT>.sharepoint.com/_layouts/appregnew.aspx ,“在客户端计算机上运行的应用程序”选项被禁用,SharePoint 在线网站中是否有启用此设置的设置?

最佳答案

经过多次尝试,我成功了

我想这不是最精彩的代码,但它是:

/// <summary>
/// Sets needed values
/// </summary>
/// <param name="clientId">The ClientId from the application</param>
/// <param name="redirectUri">The RedirectUri where the browser has to be send.</param>
/// <param name="resource">The source you want to access</param>
public OneDriveConnection(string clientId, string clientSecret, string redirectUri, string resource)
{
this._clientId = clientId;
this._redirectUri = Uri.EscapeDataString(redirectUri);
this._resource = Uri.EscapeDataString(resource);
this._clientSecret = clientSecret;
}

接下来我创建一个浏览器,提示用户登录:

/// <summary>
/// Authorizes the application
/// </summary>
public void Authorize()
{
/* EXAMPLE: GET https://login.windows.net/common/oauth2/authorize
* ?response_type=code
* &client_id=acb81092-056e-41d6-a553-36c5bd1d4a72
* &redirect_uri=https://mycoolwebapp.azurewebsites.net
* &resource=https:%2f%2foutlook.office365.com%2f
* &state=5fdfd60b-8457-4536-b20f-fcb658d19458 */

string baseUri = "https://login.windows.net/common/oauth2/authorize";
string authorizationUri = string.Format(baseUri
+ "?response_type=code"
+ "&client_id={0}"
+ "&redirect_uri={1}"
+ "&resource={2}"
+ "&state={3}", this._clientId, this._redirectUri, this._resource, "5fdfd60b-8457-4536-b20f-fcb658d19458");

// Create the form
Form webBrowserForm = new Form();
webBrowserForm.MaximizeBox = false;
webBrowserForm.MinimizeBox = false;
webBrowserForm.Size = new System.Drawing.Size(580, 890);
webBrowserForm.Text = "Webbrowser";
webBrowserForm.FormBorderStyle = FormBorderStyle.FixedDialog;
webBrowserForm.StartPosition = FormStartPosition.CenterScreen;

// Create the WebBrowser
WebBrowser webBrowser = new WebBrowser();
webBrowser.Width = 580;
webBrowser.Height = 890;
webBrowser.Location = new System.Drawing.Point(0, 0);
webBrowser.ShowPageSetupDialog();

// Hook event to the webBrowser
webBrowser.Navigated += webBrowser_Navigated;

// Show the webBrowser and form to the user
webBrowserForm.Controls.Add(webBrowser);
webBrowserForm.Show();

// Navigate to the authorizationUri
webBrowser.Navigate(authorizationUri);
}

这里我检查是否有执行GetTokenInformation方法的代码:

/// <summary>
/// When the url has code in it and contains a session_state get the code and do the GetTokenInformation
/// </summary>
private void webBrowser_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
if (e.Url.AbsoluteUri.Contains("code=") && e.Url.AbsoluteUri.Contains("session_state"))
{
string[] splited = e.Url.AbsoluteUri.Split(new char[] { '=', '&' });
_code = splited[1];

if (!string.IsNullOrWhiteSpace(_code)
&& !string.IsNullOrWhiteSpace(_redirectUri)
&& !string.IsNullOrWhiteSpace(_clientId))
{
GetTokenInformation(_code, _redirectUri, _clientId, _clientSecret);
}
else
{
_connected = false;
}
}
}

在 GetTokenInformation 方法中,我获取 TokenInformation,我使用 Newtonsoft.Json dll 将其放入 TokenInformation 类中

/// <summary>
/// This method gets tokeninformation: access_token, token_type, expires_in, resource, refresh_token, scope, id_token
/// </summary>
/// <param name="code">Code from the authorize request</param>
/// <param name="redirectUri">Reply url for your application</param>
/// <param name="clientId">Your applications client id in Windows Azure Directory</param>
/// <param name="clientSecret">Your applications client secret</param>
private void GetTokenInformation(string code, string redirectUri, string clientId, string clientSecret)
{
// Get the token information that is set above in the constructor with the help of the clientId, clientSecret and code and as well as the redirectUri without it you can't connect to it otherwise it will crash if you don't do it like that
string baseUri = "https://login.windows.net/common/oauth2/token";
string parameters = string.Format("grant_type=authorization_code"
+ "&code={0}"
+ "&redirect_uri={1}"
+ "&client_id={2}"
+ "&client_secret={3}", code, redirectUri, clientId, clientSecret);
string response = HttpPost(baseUri, parameters);

if (!string.IsNullOrWhiteSpace(response))
{
_tokenInformation = JsonConvert.DeserializeObject<TokenInformation>(response);
_connected = true;
}
else
{
_connected = false;
}
}

这是我使用 Newtonsoft.Json dll 的 TokenInformation 类:

[JsonObject(MemberSerialization.OptIn)]
class TokenInformation
{
[JsonProperty(PropertyName = "access_token")]
public string AccessToken { get; set; }

[JsonProperty(PropertyName = "token_type")]
public string TokenType { get; set; }

[JsonProperty(PropertyName = "expires_in")]
public int ExpiresIn { get; set; }

[JsonProperty(PropertyName = "expires_on")]
public int ExpiresOn { get; set; }

[JsonProperty(PropertyName = "resource")]
public string Resource { get; set; }

[JsonProperty(PropertyName = "refresh_token")]
public string RefreshToken { get; set; }

[JsonProperty(PropertyName = "scope")]
public string Scope { get; set; }

[JsonProperty(PropertyName = "id_token")]
public string IdToken { get; set; }
}

这是我找到连接到 SharePoint/Office365 所需的请求的地方:link
