Question

如何从此服务（http://192.168.1.18/service/test）中选择一些数据，该数据的值> {“数字”：“ 11224455”，“名称”：“ person1”} 。基本授权：{用户名：“ admin”，密码：“ pass123”}

这是使用基本身份验证在C＃中发出POST请求的示例：出错，原因：远程服务器返回错误：（401）未经授权。用户名和密码放在哪里？

using System;
using System.IO;
using System.Net;
using System.Text;

namespace Examples.System.Net
{
    public class WebRequestPostExample
    {
        public static void Main ()
        {
            // Create a request using a URL that can receive a post. 
            WebRequest request = WebRequest.Create ("http://192.168.1.18/service/test");
            // Set the Method property of the request to POST.
            request.Method = "POST";
            // Create POST data and convert it to a byte array.
            string postData = "This is a test that posts this string to a Web server.";
            byte[] byteArray = Encoding.UTF8.GetBytes (postData);
            // Set the ContentType property of the WebRequest.
            request.ContentType = "application/x-www-form-urlencoded";
            // Set the ContentLength property of the WebRequest.
            request.ContentLength = byteArray.Length;
            // Get the request stream.
            Stream dataStream = request.GetRequestStream ();
            // Write the data to the request stream.
            dataStream.Write (byteArray, 0, byteArray.Length);
            // Close the Stream object.
            dataStream.Close ();
            // Get the response.
            WebResponse response = request.GetResponse ();
            // Display the status.
            Console.WriteLine (((HttpWebResponse)response).StatusDescription);
            // Get the stream containing content returned by the server.
            dataStream = response.GetResponseStream ();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader (dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd ();
            // Display the content.
            Console.WriteLine (responseFromServer);
            // Clean up the streams.
            reader.Close ();
            dataStream.Close ();
            response.Close ();
        }
    }
}

由于您的评论似乎暗示它是一个结果JSON对象：

使用需要捕获的属性声明您的课程：

public class Person
{

    public int number { get; set; }
    public string name { get; set; }
}

然后您可以通过类似以下内容的Newtonsoft.Json捕获它：

        Person person = Newtonsoft.Json.JsonConvert.DeserializeObject<Person>(responseFromServer);
        Console.WriteLine("id: {0}, name: {1}", person.name, person.number);
