我正在尝试将 OneDrive for Busines 集成到 Web 窗体应用程序。
为此,我使用了 this url 中给出的文档。
在网络表单应用程序中,我有两个页面:
第一个是登录页面,它有一个登录按钮
在登录按钮单击我使用以下代码创建对 OneDrive for Business API 的 GET 请求:
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;
当我单击登录按钮时,它会将我带到 micorosoft 登录服务并将我发送回
callback.aspx
带有访问代码的页面(在 azure 上配置的重定向 URI)我得到了访问代码。
在第二页上,我兑换访问代码并发出 POST 请求以获取身份验证 token 。
这是第二页的代码:
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);
}
}
但是我收到以下错误而不是 Response 。其中包括
grant_type
在网址中。我已经添加了(你可以 checkin 代码)。我得到同样的错误同样的错误而不包括它。
这是错误
{"error":"invalid_request","error_description":"AADSTS90014: The request body must contain the following parameter: 'grant_type'.\r\nTrace ID: 2adb3a7f-ceb1-4978-97c4-3dc2d3cc3ad4\r\nCorrelation ID: 29fb11a0-c602-4891-9299-b0b538d75b5f\r\nTimestamp: 2015-07-15 09:58:42Z","error_codes":[90014],"timestamp":"2015-07-15 09:58:42Z","trace_id":"2adb3a7f-ceb1-4978-97c4-3dc2d3cc3ad4","correlation_id":"29fb11a0-c602-4891-9299-b0b538d75b5f","submit_url":null,"context":null}
请帮助知道哪里或什么地方出错了。
任何形式的帮助都是可观的
最佳答案
您正在将参数添加到请求查询字符串中。您必须在请求正文中发布数据。
var content = new StringContent(
"grant_type=authorization_code" +
"&client_id=" + ClienId +
"&redirect_uri=" + Redirecturi +
"&client_secret=" + ClientSecert +
"&code=" + _accessCode +
"&resource=" + ResourcesId,
Encoding.UTF8,
"application/x-www-form-urlencoded");
var response = httpClient.PostAsync(BaseUri, content);
var result = response.Result.Content.ReadAsStringAsync();
