[英]How to use OAuth2 in RestSharp
After a couple of days sorting out OAuth2 at the server-end (Spring java) I started working on the client written in C#. 在服务器端(Spring java)整理出OAuth2几天之后,我开始研究用C#编写的客户端。 I am using RestSharp to call my web API but I am having real difficulty with the OAuth2. 我正在使用RestSharp来调用我的Web API,但我对OAuth2有很大的困难。 There is hardly any documentation and the few examples I found online do not work. 几乎没有任何文档,我在网上找到的几个例子都不起作用。 Can someone provide me a code sample that is up to date and that I can use? 有人能为我提供一个最新的代码示例,我可以使用吗?
So far I have the following: 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);
I am simply running this code in debug mode and when I look into the response I get unauthorized. 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。
When I do curl on the console with the same parameters it works fine but it seems I can't make this to work in C#. 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。 Here is the curl command: 这是curl命令:
curl -H "Accept: application/json" client-app:secret@example.com/myapi/oauth/token -d grant_type=client_credentials
By the way, I have replaced my true API urls and other information with placeholders. 顺便说一句,我用占位符替换了我的真实API网址和其他信息。
See RFC 6749 - 4.4.2. 请参阅RFC 6749 - 4.4.2。 Client Credentials - Access Token Request 客户端凭据 - 访问令牌请求
Here is the basic format of the request 这是请求的基本格式
POST /token HTTP/1.1
Host: server.example.com
Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
Content-Type: application/x-www-form-urlencoded
grant_type=client_credentials
Your cURL request 您的cURL请求
curl -H "Accept: application/json" \
-d grant_type=client_credentials \
client-app:secret@example.com/myapi/oauth/token
The reason your cURL command works 您的cURL命令工作的原因
Content-Type
(if not specified) with POST (default when you use -d
switch) is application/x-www-form-urlencoded
使用POST的默认Content-Type
(如果未指定)(使用-d
开关时为默认值)是application/x-www-form-urlencoded
Default authentication type, if not specified, is Basic . 默认身份验证类型(如果未指定)是Basic 。 The username and password are passed either through the -u
option or in the URL 用户名和密码通过-u
选项或URL传递
-u username:password (client-app:secret) -- or put it in the url -- client-app:secret@example.com/myapi/oauth/token
You could also specify the auth type with --basic
or --digest
您还可以使用--basic
或--digest
指定身份验证类型
You can use the -v
switch in your cURL command to see all the headers involved in the request. 您可以在cURL命令中使用-v
开关来查看请求中涉及的所有标头。
RestSharp fix: RestSharp修复:
Set the Content-Type
to application/x-www-form-urlencoded
将Content-Type
设置为application/x-www-form-urlencoded
Add the Basic authentication 添加基本身份验证
client.Authenticator = new HttpBasicAuthenticator("client-app", "secret");
Get rid of 摆脱
request.AddParameter("client_id", "client-app"); request.AddParameter("client_secret", "secret");
Set the Accept
header to application/json
将Accept
标头设置为application/json
I am able to get both of the following functions worked. 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);
}

/// <returns>GitHubUser</returns>
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);
}
