问题描述

我正在尝试将OneDrive for Business集成到Web表单应用程序。

为此，我使用此URL提供的文档。 b $ b

https://dev.onedrive.com/auth/ aad_oauth.htm

在Web表单应用程序中我有两个页面。
第一个是登录页面，其中有一个登录按钮

在按钮登录中单击我正在使用
发送GET请求到OneDrive for Business API以下
$
以下代码

I m trying to integrate the OneDrive for Business to a Web Form App.
For this i am using the documentation given at this url

https://dev.onedrive.com/auth/aad_oauth.htm
In web Form App I have two Page
First one is Login page which have a button for login
In button login click i am making a GET Request to OneDrive for Business API using

the following code

HttpClient client = new HttpClient();
            Redirecturi = Uri.EscapeDataString(Redirecturi);
            string url = string.Format

("https://login.windows.net/common/oauth2/authorize?response_type=code&client_id=

{0}&redirect_uri={1}", ClienId, Redirecturi);
            var response = client.GetAsync(url);
            var json = response.Result.Content.ReadAsStringAsync();
            Label2.Text = json.Result;

$
当我点击在登录按钮上它带我到micorosoft登录服务并发送




我回到带有访问代码的callback.aspx页面（在azure上配置重定向URi）



我获得了访问代码

在第二页我正在兑换访问代码和 发出POST请求以获得


$
身份验证令牌

以下是第二页的代码。

When I Click on login button it is taking me to micorosoft login servie and sending

me back to callback.aspx page with access code (Redirect URi configured on azure)

I got the access code
On second page i am redeeming the access code and  making a POST request to get the

Authentication token
Here is the code for the second page.

 private string BaseUri="https://login.windows.net/common/oauth2/token";
        public string Redirecturi = "http://localhost:51642/CallBack.aspx";
        public string ResourcesId = "https://api.office.com/discovery/";
        private string ClienId = "180c6ac4-5829-468e-.....-822405804862";

///truncated//azure
        private string ClientSecert =

"G4TAQzD8d7C4...OE6m366afv8XKbTCcyXr4=";//truncated
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!string.IsNullOrEmpty(Request.QueryString

[OAuthConstants.AccessToken]))
            {
                // There is a token available already. It should be the token flow.

Ignore it.
                return;
            }
            if (!string.IsNullOrEmpty(Request.QueryString[OAuthConstants.Code]))
            {
                string _accessCode = Request.QueryString[OAuthConstants.Code];
                HttpClient client = new HttpClient();
               // BaseUri = Uri.EscapeDataString(BaseUri);
                Redirecturi = Uri.EscapeDataString(Redirecturi);
                ResourcesId = Uri.EscapeDataString(ResourcesId);
                string url = string.Format("{0}?client_id={1}&redirect_uri={2}

&grant_type=authorization_code&client_secret={3}&code={4}

&grant_type=authorization_code&resource={5}", BaseUri, ClienId, Redirecturi,

ClientSecert, _accessCode, ResourcesId);
                var response = client.PostAsync(url, null);
                var json = response.Result.Content.ReadAsStringAsync();
                Response.Write(json);
            }
        }

But instead of Response i am getting following error. Which say include the

grant_type in url. I already added (u can check in code).
Without including this also i am getting same error.

**Here is error**

{"error":"invalid_request","error_description":"AADSTS90014: The request body must
