POST 使用 HttpClient 从内容类型 application/x-www-form-urlencoded 使用 grant_type 和范围

Question

我正在尝试使用以下代码从端点获取令牌。

 var bodyContents = new Dictionary<string, string>
        {
            { "grant_type", "client_credentials" },
            { "userName", "loremipsum" },
            { "password", "xxxxxxx"},
            { "scope", "read_rulesengine write_rulesengine" }
        };

        string responseContents = string.Empty;

        var client = new HttpClient();
        client.BaseAddress = new Uri("https://test-sts-dev.test.com");
        var req = new HttpRequestMessage(HttpMethod.Post, "/oauth/ls/connect/token");
        req.Content = new FormUrlEncodedContent(bodyContents);
        var postResponse = await client.SendAsync(req);
        postResponse.EnsureSuccessStatusCode();

        if (!postResponse.IsSuccessStatusCode)
            throw new HttpRequestException("Access denied by token issuer. Check credentials in <encryptedSettings> of config file and try again.");

        responseContents = postResponse.Content.ReadAsStringAsync().Result;
        var responseObject = JObject.Parse(responseContents);

        return responseObject.Value<string>("access_token");

现在我认为我所做的一切都是正确的，但我得到的回应是 BadRequest

以下是我得到的回复：

{Method: POST, RequestUri: 'https://test-sts-dev.test.com/oauth/ls/connect/token', Version: 1.1, Content: System.Net.Http.FormUrlEncodedContent, Headers:
{
  Content-Type: application/x-www-form-urlencoded
  Content-Length: 125
}}

Answer 1

我们会发现我缺少请求中的授权设置：

req.Headers.Add("Authorization", "Basic " + auth); // auth will be string visible in postman after Basic

放置这个开始给我结果。
