Asp.net 使用HTTP身份验证调用RESTAPI

我必须安全地调用

restapi

。我有一个

authenticate API

，它返回一个令牌。我需要将这个令牌添加到我正在调用的API中

这是我所知道的调用

restapi

的常用方法。我需要将字符串标记附加到此请求

        // *** Establish the request 
        string token= getAuthenticate(username,password,out token );
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(lcUrl);
        // *** Retrieve request info headers
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        StreamReader loResponseStream = new StreamReader(response.GetResponseStream());
        string lcHtml = loResponseStream.ReadToEnd();
        response.Close();
        loResponseStream.Close();

不知道有什么问题。。。要从Rest Uri获取响应，可以执行以下操作：

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(yourUrl + token); // Append Here
        request.Method = "GET"; // GET or POST Define Here
        //http.Accept = "application/json"; // Add if require
        //http.ContentType = "application/json"; // Add if require
        String test = String.Empty;
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        {
            Stream dataStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(dataStream);
            test = reader.ReadToEnd();
            reader.Close();
            dataStream.Close();
        }

或

您可以通过

网络客户端使用简单请求

：

例如：

WebClient webClient = new WebClient();
string json = string.Empty;
// Downloads JSon String
json = webClient.DownloadString("http://api.openweathermap.org/data/2.5/weather?q=London,uk"); // Replace your URL + Token...

还有第三方组件可用=

RestSharp

我使用的是

HttpClient

，没有任何不同。我觉得这样更干净：

你面临的问题是什么？有错误吗？你的问题不清楚。。。

var uri = "http://example.com";
using (HttpClient httpClient = new HttpClient())
{
     httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token_you_want_to_used);

     var response = await httpClient.GetAsync(uri);
     string result = await response.Content.ReadAsStringAsync();

}
