使用Twilio的卷曲与HttpClient

问题描述

我有来自Twilio的API，我想知道如何使用HttpClient来利用这个卷曲，以便我可以在我的应用程序中使用它？

I have below API from Twilio and I want to know how can utilize this curl using HttpClient so that I can use it in my app?

我也需要传递参数，例如  Body，From，To等..

I need to pass parameters too, e.g. Body, From, To, etc..

curl
'https://api.twilio.com/2010-04-01/Accounts/ ACxxxxxxxxxxxxxxxxx529d6d / Messages.json'
-X POST \ -u ACxxxxxxxxxxxxxxxxx529d6d：[AuthToken]

我尝试了下面的代码，但得到了：

I tried below code but getting:

/Users/jassim/Projects/TwilioTest/TwilioTest/TwilioTestPage.xaml.cs(62,62）：错误CS1729：'AuthenticationHeaderValue'不包含带3个参数的构造函数（CS1729）（TwilioTest）

/Users/jassim/Projects/TwilioTest/TwilioTest/TwilioTestPage.xaml.cs(62,62): Error CS1729: 'AuthenticationHeaderValue' does not contain a constructor that takes 3 arguments (CS1729) (TwilioTest)

public async Task<HttpResponseMessage> SendReq()
{
    var accountSid = "zzzzzzzzzzz";
    var authToken = "xxxxxxxxxxx";
    var targeturi = "https://api.twilio.com/2010-04-01/Accounts/{0}/SMS/Messages";
    string from = "+0000000000";
    string to = "WoWSender";
    string message = "Test Message";

    var client = new System.Net.Http.HttpClient();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", accountSid, authToken);
    // client.DefaultRequestHeaders.Authorization = CreateAuthenticationHeader("Basic", accountSid, authToken);

    var content = new StringContent(string.Format("From={0}&amp;To={1}&amp;Body={2}", from, to, message));
    content.Headers.ContentType = new MediaTypeHeaderValue("application/x-www-form-urlencoded");

    var response = await client.PostAsync(string.Format(targeturi, accountSid), content);
    if (response.IsSuccessStatusCode)
    {
        //the POST succeeded, so update the UI accordingly
    }
    else
    {
        //the POST failed, so update the UI accordingly
    }
    return response;
}

谢谢，

谢谢你在这里发布。

对于您的问题，AuthenticationHeaderValue有两个构造函数。您使用的具有三个参数的构造函数不存在。

For your question, the AuthenticationHeaderValue has two constructors. The constructor with three parameters which you used does not exist.

以下是有关构造函数的msdn文档供您参考。

Here is the msdn document about the constructor for your reference.

以下是AuthenticationHeaderValue类的用法。将所有字符串放入一个参数中。请参阅链接中的示例。

Here is the usage of AuthenticationHeaderValue class. Put all the strings into one parameter. Please refer to the example in the link.
