如何将curl请求转换为C＃中的WebRequest？

Question

我试图卷曲的请求转换为WebRequest在C＃中，但没能得到回应，因为它总是返回401未经授权错误

这里是工作卷曲要求：

curl -k -v https://api.demo.peertransfer.com/v1/transfers -H“Content-Type：application/json”-X POST -d“{\”provider \“：\”HUL \“，\”payment_destination \“：\”hult-applicationfee \“， \“amount \”：“29000”，“callback_url”：\“http://studentapplication.local/en/nextsteps \”，\“callback_id \”：\“abc1234546asas \”，\“dynamic_fields \”：{\“student_id \ “32453245 \”，\“ST udent_first_name \ “：\” 糖果\ “\ ”student_last_name \“：\ ”学生\“}}” -H “X-Peertransfer-文摘：zYUt + Pn0A06wsSbCrrbAZn68Aslq9CbSUAKBrUEwIzI =”

输出：

结果在红盒子是什么，我需要在WebRequest反应得到， 这里是我的C＃代码

private void testnewfunc() 
{ 
    string value = "{\"provider\":\"HUL\",\"payment_destination\":\"hult-applicationfee\",\"amount\":\"29000\",\"callback_url\":\"http://studentapplication.local/en/nextsteps\",\"callback_id\":\"abc1234546asas\",\"dynamic_fields\":{\"student_id\":\"32453245\",\"student_first_name\":\"Candy\",\"student_last_name\":\"Student\"}}"; 
    var URI = new Uri("https://api.demo.peertransfer.com/v1/transfers"); 
    byte[] data = System.Text.ASCIIEncoding.Default.GetBytes(value); 
    var requst = (HttpWebRequest)WebRequest.Create(URI); 
    requst.UserAgent = "curl/7.43.0"; 
    requst.Method = "POST"; 
    requst.KeepAlive = true; 
    requst.AllowAutoRedirect = true; 
    requst.ContentType = " application/json"; 
    requst.ContentLength = data.Length; 
    // wc.Headers["Content-Type"] = "application/json"; 
    requst.Accept = "*/*"; 
    //Or any other encoding type. 
    string result = System.Convert.ToBase64String(data);   

    var uname = "hultdemo2015"; 
    var pword = "gEejgC0GF8pCbI7C"; 
    var creds = string.Format("{0}:{1}", uname, pword); 
    creds = Convert.ToBase64String(Encoding.ASCII.GetBytes(creds)); 

    requst.Headers["Authorization"] = string.Format("{0} {1}", "Basic", creds);    
    requst.Headers["X-Peertransfer-Digest"] = string.Format("{0}", "zYUt+Pn0A06wsSbCrrbAZn68Aslq9CbSUAKBrUEwIzI="); 
    using (Stream stream = requst.GetRequestStream()) 
    { 
     stream.Write(data, 0, data.Length); 
    } 
    var httpResponse = (HttpWebResponse)requst.GetResponse(); 
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) 
    { 
     var responseText = streamReader.ReadToEnd(); 
     //Now you have your response. 
     //or false depending on information in the response 
     // return true; 
    } 
} 

不知道什么，我在作出错误。

这里是我的解决方案：

var client = new HttpClient(new HttpClientHandler { AllowAutoRedirect = false }); 

var message = new HttpRequestMessage(HttpMethod.Post, new Uri("https://api.demo.peertransfer.com/v1/transfers")); 
message.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("*/*")); 
message.Headers.Add("X-Peertransfer-Digest", "zYUt+Pn0A06wsSbCrrbAZn68Aslq9CbSUAKBrUEwIzI="); 
message.Content = new StringContent("{\"provider\":\"HUL\",\"payment_destination\":\"hult-applicationfee\",\"amount\":\"29000\",\"callback_url\":\"http://studentapplication.local/en/nextsteps\",\"callback_id\":\"abc1234546asas\",\"dynamic_fields\":{\"student_id\":\"32453245\",\"student_first_name\":\"Candy\",\"student_last_name\":\"Student\"}}", Encoding.UTF8, "application/json"); 
var responseMessage = await client.SendAsync(message); 
MessageBox.Show(string.Format("Status Code: {0}{1}Content-Type: {2}{1}Date: {3}{1}Location:{4}", responseMessage.StatusCode, Environment.NewLine, responseMessage.Content.Headers.ContentType, responseMessage.Headers.Date, responseMessage.Headers.Location)); 

下面是来自服务器的响应（同卷曲）：

版本与.NET 4.0

var data = "{\"provider\":\"HUL\",\"payment_destination\":\"hult-applicationfee\",\"amount\":\"29000\",\"callback_url\":\"http://studentapplication.local/en/nextsteps\",\"callback_id\":\"abc1234546asas\",\"dynamic_fields\":{\"student_id\":\"32453245\",\"student_first_name\":\"Candy\",\"student_last_name\":\"Student\"}}"; 

var request = (HttpWebRequest)WebRequest.Create(new Uri("https://api.demo.peertransfer.com/v1/transfers")); 
request.Method = "POST"; 
request.AllowAutoRedirect = false; 
request.Accept = "*/*"; 
request.Headers.Add("X-Peertransfer-Digest", "zYUt+Pn0A06wsSbCrrbAZn68Aslq9CbSUAKBrUEwIzI="); 
request.ContentType = "application/json"; 
request.ContentLength = data.Length; 

using (var reqStream = request.GetRequestStream()) 
using (var writer = new StreamWriter(reqStream)) 
{ 
    writer.Write(data); 
} 

var response = request.GetResponse(); 
MessageBox.Show(response.Headers.ToString()); 

兼容

确保你有这些using语句：

using System.IO; 
using System.Net; 

，这些都是来自服务器的响应头：
