NetFramework转换为Net Core（HttpWebRequest）

Question

我有一个4.5 net fw的库。我需要做同样的事情，但对于网络核心。

大啤酒人可同时修复这个..

Code from VS with errors (screen) 我的代码：

string returnData = String.Empty; 

      var webRequest = HttpWebRequest.Create(url) as HttpWebRequest; 
      if (webRequest != null) 
      { 
       webRequest.Accept = "*/*"; 
       webRequest.UserAgent = ".NET"; 
       webRequest.Method = method; 
       webRequest.ContentType = "application/json"; 
       webRequest.Host = "coinbase.com"; 

       string nonce = Convert.ToInt64(DateTime.Now.Ticks).ToString(); 
       string message = nonce + url; 
       string signature = HashEncode(HashHMAC(StringEncode(API_SECRET), StringEncode(message))); 

       var whc = new WebHeaderCollection(); 
       whc.Add("ACCESS_KEY: " + API_KEY); 
       whc.Add("ACCESS_SIGNATURE: " + signature); 
       whc.Add("ACCESS_NONCE: " + nonce); 
       webRequest.Headers = whc; 

       using (WebResponse response = webRequest.GetResponse()) 
       { 
        using (Stream stream = response.GetResponseStream()) 
        { 
         StreamReader reader = new StreamReader(stream); 
         returnData = reader.ReadToEnd(); 
        } 
       } 
      }

您可以如下使用我的代码。希望能够帮助，我的朋友：

var webRequest = WebRequest.Create(url) as HttpWebRequest; 
      if (webRequest != null) 
      { 
       webRequest.Accept = "*/*"; 
       webRequest.UserAgent = ".NET"; 
       webRequest.Method = WebRequestMethods.Http.Post; 
       webRequest.ContentType = "application/json"; 
       webRequest.Host = "coinbase.com"; 

       var whc = new WebHeaderCollection 
       { 
        "ACCESS_KEY: " + API_KEY, 
        "ACCESS_SIGNATURE: " + signature, 
        "ACCESS_NONCE: " + nonce 
       }; 
       webRequest.Headers = whc; 

       using (WebResponse response = webRequest.GetResponse()) 
       { 
        using (Stream stream = response.GetResponseStream()) 
        { 
         StreamReader reader = new StreamReader(stream); 
         returnData = reader.ReadToEnd(); 
        } 
       } 
      }
