在服务器端(Spring java)整理OAuth2几天之后,我开始研究用C#编写的客户端。我正在使用RestSharp来调用我的Web API,但我对OAuth2有很大的困难。几乎没有任何文档,我在网上找到的几个例子都不起作用。有人能为我提供最新的代码示例吗?我可以使用吗?
到目前为止,我有以下内容:
var client = new RestClient("http://example.com/myapi/oauth/token");
RestRequest request = new RestRequest() { Method = Method.POST };
request.AddHeader("Content-Type", "application/json");
request.AddParameter("grant_type", "client_credentials");
request.AddParameter("client_id", "client-app");
request.AddParameter("client_secret", "secret");
var response = client.Execute(request);
我只是在调试模式下运行此代码,当我查看响应时,我未经授权。
当我使用相同的参数在控制台上卷曲时它工作正常,但似乎我不能使它在C#中工作。这是curl命令:
curl -H "Accept: application/json" client-app:secret@example.com/myapi/oauth/token -d grant_type=client_credentials
顺便说一下,我已经用占位符替换了我的真实API网址和其他信息。

请参阅RFC 6749 - 4.4.2. Client Credentials - Access Token Request
以下是请求的基本格式
POST /token HTTP/1.1
Host: server.example.com
Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
Content-Type: application/x-www-form-urlencoded
grant_type=client_credentials
您的cURL请求
curl -H "Accept: application/json" \
-d grant_type=client_credentials \
client-app:secret@example.com/myapi/oauth/token
你的cURL命令工作的原因
Content-Type
(如果未指定)(默认使用-d
切换时)为application/x-www-form-urlencoded
默认身份验证类型(如果未指定)为Basic。用户名和密码通过-u
选项或URL
-u username:password (client-app:secret)
-- or put it in the url --
client-app:secret@example.com/myapi/oauth/token
您还可以使用--basic
或--digest
您可以使用cURL命令中的-v
开关查看请求中涉及的所有标头。
RestSharp 修复:
将Content-Type
设置为application/x-www-form-urlencoded
添加基本身份验证
client.Authenticator = new HttpBasicAuthenticator("client-app", "secret");
摆脱
request.AddParameter("client_id", "client-app");
request.AddParameter("client_secret", "secret");
将Accept
标题设置为application/json

我能够完成以下两个功能。
public RestClient getClient2(string user, string token)
{
RestClient client = new RestClient();
client.BaseUrl = new Uri(baseUrl);
client.Authenticator = new HttpBasicAuthenticator(user, token);
//client.Authenticator = new OAuth2UriQueryParameterAuthenticator(token); //works
//client.Authenticator = new OAuth2AuthorizationRequestHeaderAuthenticator(token); // doesn't work
return client;
}
public GitHubUser GetGitHubUser2()
{
RestRequest request = new RestRequest();
request.Resource = "/users/huj";
request.RootElement = "GitHubUser";
RestClient client = getClient2(myUser, myToken);
return Execute<GitHubUser>(client, request);
}

public GitHubUser GetGitHubUser3()
{
//RestRequest request = new RestRequest(Method.POST); //empty data
RestRequest request = new RestRequest();
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
request.AddHeader("Accept", "application/json");
request.AddParameter("grant_type", "client_credentials");
request.Resource = "/users/huj";
request.RootElement = "GitHubUser";
RestClient client = getClient2(myUser, myToken);
return Execute<GitHubUser>(client, request);
}
