将代码从 RestSharp 转换为 HttpClient

Question

有人可以帮我将这个使用 RestSharp 的 ASP .Net Core 示例（用于我的 Web Api 以使用来自 Auth0 的管理 API）转换为使用 HttpClient 的示例吗？

var client = new RestClient("https://YOUR_AUTH0_DOMAIN/oauth/token");
var request = new RestRequest(Method.POST);
request.AddHeader("content-type", "application/json");
request.AddParameter("application/json", "{\"grant_type\":\"client_credentials\",\"client_id\": \"YOUR_CLIENT_ID\",\"client_secret\": \"YOUR_CLIENT_SECRET\",\"audience\": \"https://YOUR_AUTH0_DOMAIN/api/v2/\"}", ParameterType.RequestBody);
IRestResponse response = client.Execute(request);

我一直在挣扎……我有这个：

var client = new HttpClient();
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.BaseAddress = new Uri("https://YOUR_AUTH0_DOMAIN/oauth/token");

但我不确定其余的...谢谢

您需要获取请求正文并创建要发布的内容

var client = new HttpClient();
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.BaseAddress = new Uri("https://YOUR_AUTH0_DOMAIN/oauth/token");

var json = "{\"grant_type\":\"client_credentials\",\"client_id\": \"YOUR_CLIENT_ID\",\"client_secret\": \"YOUR_CLIENT_SECRET\",\"audience\": \"https://YOUR_AUTH0_DOMAIN/api/v2/\"}"
var content = new StringContent(json, Encoding.UTF8, "application/json");

var response = await client.PostAsync("", content);
