http://sendloop.com/help/article/api-001/工具入门

我的账户是code5所以我尝试2 codeS得到systemDate。

My account is "code5" so i tried 2 codes to get systemDate.

1。 code

        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";

但我不知道我正确的API使用由上面codeS？

But i don't know that i use correctly api by above codes ?

在我上面codeS我没有看到任何数据或任何使用。

When i use above codes i don't see any data or anything.

我怎样才能和岗位API来Sendloop.And我如何才能通过使用WebRequest的使用API​​？

How can i get and post api to Sendloop.And how can i use api by using WebRequest ?

我将使用.NET API第一次如此

I will use api first time in .net so

任何帮助将AP preciated。

感谢。

推荐答案

它看起来像你需要做的请求时，发表您的API密钥到端点。否则，你将不会被验证，它会返回一个空的响应。

It looks like you need to post your API key to the endpoint when making requests. Otherwise, you will not be authenticated and it will return an empty response.

要发送POST请求，你需要做这样的事情：

To send a POST request, you will need to do something like this:

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();
}
