我在Asp.net中对Twilio发送sms api发出post请求时出错

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

我发出post请求通过我的aspx页面发送短信，但我得到了一个身份验证错误

这是代码。谁能告诉我是什么问题吗

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();

运行此代码时，会出现以下错误：

{"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}

我应该做什么改变

编辑更改

 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());
            }
        }

我仍然会遇到同样的错误。

这段代码有很多问题。错误本身已经相当清楚了；此请求提供了一个响应，您应该阅读：

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，然后单击。代码中的问题：

您只需在请求URI中提供帐户ID，因此将丢失

+：“+authenticationToken

您没有正确写入基本身份验证标头。“Basic”和base64编码凭据之间缺少空格

借用刚刚发布的其他答案：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，使用客户端库。你不想重新发明轮子

特别是如果您查看最后一点，所有这些代码都可以替换为以下代码：

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!", ...);

这里是Twilio开发者福音传道者

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

您的授权标头似乎设置不正确，在“Basic”和

authInfo

之间没有空格

您还将请求类型设置为“application/json”

Twilio实际上提供了一个可用于在Asp.net中更轻松地发送消息的工具。您不必担心HTTP请求的基本设置，只需继续构建应用程序即可。

。您没有在请求URI中使用令牌。@CodeCaster不需要这样做。Jui只是在学习。@philnash一个人不读书怎么能学习？我也不觉得我之前的评论特别具有攻击性、敌意或“像那样”。它不是特别友好。我希望StackOverflow会更欢迎新开发人员。我认为您下面的实际答案要好得多，感谢您的跟进：）我像@CodeCaster那样做，但我只想通过post请求来做。
