连接到Twitter - RestSharp OAuth2

Question

我试图通过这些说明连接到Twitter API

https://dev.twitter.com/docs/auth/application-only-auth

这是我的代码:

var baseUrl = "http://api.twitter.com/";
var client = new RestClient(baseUrl);                     
var request = new RestRequest("/oauth2/token", Method.POST);

var concat = ConfigurationManager.AppSettings["TwitterConsumerKey"] + ":" +
     ConfigurationManager.AppSettings["TwitterConsumerSecret"];

string encodeTo64 = concat.EncodeTo64();

request.AddHeader("Authorization", "Basic " + encodeTo64);
request.AddHeader("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
request.AddBody("grant_type=client_credentials");
IRestResponse restResponse = client.Execute(request);

EncodeTo64

static public string EncodeTo64(this string toEncode)
    {
        byte[] toEncodeAsBytes
              = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode);
        string returnValue
              = System.Convert.ToBase64String(toEncodeAsBytes);
        return returnValue;
    }

Response.Content如下

"{\"errors\":[{\"code\":170,\"label\":\"forbidden_missing_parameter\",\"message\":\"Missing required parameter: grant_type\"}]}"

这部分错了吗？

request.AddBody("grant_type=client_credentials");

我已经验证我的凭据是正确的(我之前收到了这个错误,但解决了它,所以应该没问题).

Twitter 页面上的说明让我很困惑。“请求正文必须是 grant_type=client_credentials。”

至于Restsharp，它不是AddBody，而是AddParameter。

所以：

request.AddParameter("grant_type", "client_credentials");
