Question

我正在学习Twilio发送短信工具。我创建了一个试用帐户，并且还有一个经过验证的电话号码。

我发出了通过我的aspx页面发送短信的请求，但是我收到了身份验证错误。

这是代码。谁能告诉我这是什么问题？

string url ="https://api.twilio.com/2010-04-01/Accounts/"+accontSid+ ":" + authenticationToken +"/SMS/Messages.json";
HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
var authInfo = accSid + ":" + authToken;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
request.Method = "POST";
var postData = "{\"To\":" +"\"" + ToNumber + "\"" + ", \"From\":" + "\"" + FromNumber + "\"" + ", \"Body\":" + "\"" + Body + "\"}";

var data = Encoding.UTF8.GetBytes(postData);
//request.ContentType = "application/json; charset=utf-8";
request.ContentType = "application/json";
request.ContentLength = data.Length;
Stream writer = null;
writer = request.GetRequestStream();
writer.Write(data, 0, data.Length);
writer.Close();

request.Headers["Authorization"] = "Basic"+authInfo;

HttpWebResponse response = (HttpWebResponse) request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
string content = reader.ReadToEnd();

当我运行此代码时，我收到此错误：

{"code": 20003, "detail": "Your AccountSid or AuthToken was incorrect.", "message": "Authentication Error - No credentials provided", "more_info": "https://www.twilio.com/docs/errors/20003", "status": 401}

我应该做出哪些改变？

修改

 try
 {
            string url ="https://api.twilio.com/2010-04-01/Accounts/"+accountSid+"/SMS/Messages.json";

            string FromNumber = "+12012317746";
            string ToNumber = "+91xxxxxxxxxx";
            string Body = "Hello This is my test account.";


            TwilioRestClient client = new TwilioRestClient(accSid, authToken);

            HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
            var authInfo = accSid + ":" + authToken;
            authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
            request.Method = "POST";
            var postData = "{\"To\":" +"\"" + ToNumber + "\"" + ", \"From\":" + "\"" + FromNumber + "\"" + ", \"Body\":" + "\"" + Body + "\"}";

            var data = Encoding.UTF8.GetBytes(postData);
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;
            Stream writer = null;
            writer = request.GetRequestStream();
            writer.Write(data, 0, data.Length);
            writer.Close();
            request.Headers["Authorization"] = "Basic "+authInfo;
            HttpWebResponse response = (HttpWebResponse) request.GetResponse();
            StreamReader reader = new StreamReader(response.GetResponseStream());
            string content = reader.ReadToEnd();
            client.SendMessage("+12012317746 ", txtToNo.Text, txtMsg.Text);
        }
        catch (WebException ex)
        {
            using (var stream = ex.Response.GetResponseStream())
            using (var reader = new StreamReader(stream))
            {
                Response.Write(reader.ReadToEnd());
            }
        }

我仍然得到同样的错误。

Answer 1

此代码存在很多问题。错误本身已经很清楚了;此请求提供了您应该阅读的响应：

detail: Your AccountSid or AuthToken was incorrect.
message: Authentication Error - No credentials provided
more_info: https://www.twilio.com/docs/errors/20003

阅读错误，访问提到的“更多信息”页面和read the documentation。您的代码存在问题：

您只需在请求URI中提供帐户ID，因此请丢失+ ":" + authenticationToken。
您没有正确编写基本身份验证标头。您在“Basic”和base64编码的凭据之间缺少空格。
借用刚发布的其他答案：请求的内容类型也不正确。
如上面“更多信息”和文档链接中所述，请使用客户端库。你不想重新发明轮子。

特别是如果你看一下最后一点，所有这些代码都可以用以下代码替换：

string AccountSid = "AC5ef872f6da5a21de157d80997a64bd33"; 
string AuthToken = "[AuthToken]"; 
var twilio = new TwilioRestClient(AccountSid, AuthToken); 

var message = twilio.SendMessage(
    "+14158141829", "+16518675309", 
    "Hey Jenny! Good luck on the bar exam!", ...);

Answer 2

Twilio开发者传道者在这里。

这里有几个问题。正如CodeCaster指出的那样，您不需要将Auth Token作为URL的一部分，只需要帐户SID。

您的授权标题看起来好像设置不正确，您在＆＃34; Basic＆＃34;之间没有空格。和authInfo。

您还将请求类型设置为＆＃34; application / json＆＃34;。 Twilio expects your POST request to have form encoded data as the body and the content type "application/x-www-form-urlencoded"

Twilio实际上提供了一个C# helper library，您可以使用它来更轻松地在Asp.net中发送消息。您不必担心HTTP请求的基本设置，并且可以继续构建您的应用程序。

当我在Twilio上发送邮件请求时，我在Asp.net
