如何使用WebRequest類在C＃中

Question

我'嘗試使用例如API調用下面鏈接請聯繫

http://sendloop.com/help/article/api-001/getting-started

我的賬戶是「代碼4」，所以我嘗試過2個碼來獲得systemDate。

1.代碼

 var request = WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json"); 
     request.ContentType = "application/json; charset=utf-8"; 

     string text; 
     var response = (HttpWebResponse)request.GetResponse(); 

     using (var sr = new StreamReader(response.GetResponseStream())) 
     { 
      text = sr.ReadToEnd(); 
     } 

2.Code

 HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json"); 
     httpWebRequest.Method = WebRequestMethods.Http.Get; 
     httpWebRequest.Accept = "application/json"; 

但我不知道，我通過上面的代碼正確的API使用？

當我使用上述代碼時，我看不到任何數據或任何東西。

如何獲取併發布api給Sendloop.And如何使用WebRequest使用api？

我將使用API​​第一次在.NET所以

任何幫助將不勝感激。

謝謝。

看起來您需要在發出請求時將您的API密鑰發佈到端點。否則，你將不會被認證，它會返回一個空的響應。

要發送POST請求，你需要做這樣的事情：

var request = WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json"); 
request.ContentType = "application/json; charset=utf-8"; 

string postData = "APIKey=xxxx-xxxxx-xxxxx-xxxxx-xxxxx"; 

request.Method = "POST"; 
ASCIIEncoding encoding = new ASCIIEncoding(); 
byte[] data = encoding.GetBytes(postData); 
request.ContentLength = data.Length; 
Stream newStream = request.GetRequestStream(); //open connection 
newStream.Write(data, 0, data.Length); // Send the data. 
newStream.Close(); 

string text; 
var response = (HttpWebResponse)request.GetResponse(); 

using (var sr = new StreamReader(response.GetResponseStream())) 
{ 
    text = sr.ReadToEnd(); 
}
