如何在RestSharp中使用OAuth2 [英] How to use OAuth2 in RestSharp

问题描述

几天后，在服务器端（Spring Java）整理了OAuth2，我开始使用C＃编写客户端。我正在使用RestSharp调用我的Web API，但是使用OAuth2确实遇到了困难。几乎没有任何文档，我在网上发现的一些示例也不起作用。有人可以提供给我最新的代码示例并且可以使用吗？

After a couple of days sorting out OAuth2 at the server-end (Spring java) I started working on the client written in C#. I am using RestSharp to call my web API but I am having real difficulty with the OAuth2. There is hardly any documentation and the few examples I found online do not work. Can someone provide me a code sample that is up to date and that I can use?

到目前为止，我有以下内容：

So far I have the following:

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，当我调查响应时，我得到了未授权。

I am simply running this code in debug mode and when I look into the response I get unauthorized.

当我使用相同的参数在控制台上卷曲时，它可以正常工作，但看来我无法使其在C＃中工作。这是curl命令：

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#. Here is the curl command:

curl -H "Accept: application/json" client-app:[e-mail]/myapi/oauth/token -d grant_type=client_credentials

顺便说一句，我已经替换了真实的API网址以及带有占位符的其他信息。

By the way, I have replaced my true API urls and other information with placeholders.

推荐答案

请参见 RFC 6749-4.4.2。客户凭证-访问令牌请求

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:[e-mail]/myapi/oauth/token 

您的cURL命令起作用的原因

The reason your cURL command works

1. 默认 Content-Type （如果未指定） ）与POST（默认情况下，当您使用 -d 开关时）为 application / x-www-form-urlencoded



2. 默认身份验证类型（如果未指定）为基本。用户名和密码通过 -u 选项或在URL

1. Default Content-Type (if not specified) with POST (default when you use -d switch) is application/x-www-form-urlencoded

2. Default authentication type, if not specified, is Basic. The username and password are passed either through the -u option or in the URL

-u username:password (client-app:secret)

-- or put it in the url --

client-app:[e-mail]/myapi/oauth/token

您还可以使用以下方式指定身份验证类型-基本或-摘要

You could also specify the auth type with --basic or --digest

您可以在cURL命令中使用 -v 开关查看请求中涉及的所有标头。

You can use the -v switch in your cURL command to see all the headers involved in the request.

RestSharp 修复：

1. 设置内容类型到 application / x-www-form-urlencoded

添加基本身份验证

client.Authenticator = new HttpBasicAuthenticator("client-app", "secret");

摆脱

Get rid of

request.AddParameter("client_id", "client-app");
request.AddParameter("client_secret", "secret");

将 Accept 标头设置为 application / json
