问：

var uploadImagesURL = "https://localhost:57028/Photo/UploadImages?albumId="+ albumId;
cookieString = parsedFormBody.Result.GetParameterValue("Cookie");

HttpWebRequest uploadImageWebRequest = (HttpWebRequest)WebRequest.Create(uploadImagesURL);
uploadImageWebRequest.Method = "POST";
var cookies = new CookieContainer();
string[] cookiePairs = cookieString.Split(';');
foreach (string cookiePair in cookiePairs)
{
    string[] keyValue = cookiePair.Trim().Split('=');
    if (keyValue.Length == 2)
    {
        string cookieName = keyValue[0];
        string cookieValue = keyValue[1];
        var cookie = new Cookie(cookieName, cookieValue)
        {
            Domain = "localhost"
        };
        cookies.Add(cookie);
    }
}
uploadImageWebRequest.CookieContainer = cookies;                                  
HttpWebResponse uploadImageWebResponse = (HttpWebResponse)uploadImageWebRequest.GetResponse();

我创建了一个 Azure 函数，用于上传多个图像的可伸缩性，并且从 ajax 请求中，我正在调用我的 azure 函数，从 azure 函数，我正在上传到 wasabi，当图像成功上传时，我正在调用 HttpWebRequest，但在步骤（HttpWebResponse）uploadImageWebRequest.GetResponse（）;它导致错误 - System.Net.WebException：尝试以访问权限禁止的方式访问套接字

C# .NET Azure 函数 httpwebrequest

鉴于已弃用，为什么不使用呢？也很奇怪，你不能像那样连接内存流。相反，您需要先获取字节并转换为 base64 或类似版本。HttpClientWebRequest+ memoryStream

错误 - System.Net.WebException：尝试以套接字访问权限禁止的方式访问套接字

大多数情况下，这些问题都与SSL证书或安全限制有关。如果在本地运行应用程序，请尝试使用而不是http://localhost:57028https://localhost:57028

我尝试过一个示例 Web API，其中 HttpWebRequest 会将名称和值发布到 cookie。请检查以下代码。

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

namespace WebApplication2
{
    class WebApplication2
    {
        static void Main()
        {
            try
            {
                string url = "https://jsonplaceholder.typicode.com";
                string postData = "{\"title\":\"New Post\",\"body\":\"This is the post body\",\"userId\":1}";

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
                request.Method = "POST";
                request.ContentType = "application/json";

                // Convert the POST data to a byte array
                byte[] postDataBytes = Encoding.UTF8.GetBytes(postData);
                request.ContentLength = postDataBytes.Length;

                // Add cookies to the request
                request.CookieContainer = new CookieContainer();
                request.CookieContainer.Add(new Cookie("session_id", "abc123", "/", "jsonplaceholder.typicode.com"));
                request.CookieContainer.Add(new Cookie("auth_token", "xyz789", "/", "jsonplaceholder.typicode.com"));

                // Write the POST data to the request stream
                using (Stream requestStream = request.GetRequestStream())
                {
                    requestStream.Write(postDataBytes, 0, postDataBytes.Length);
                }

                // Send the request and get the response
                using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    // Read the response stream using a StreamReader
                    using (StreamReader reader = new StreamReader(response.GetResponseStream()))
                    {
                        string responseText = reader.ReadToEnd();
                        Console.WriteLine(responseText);
                    }
                }
            }
            catch (WebException ex)
            {
                if (ex.Response is HttpWebResponse response)
                {
                    Console.WriteLine("HTTP error: " + response.StatusCode);
                }
                else
                {
                    Console.WriteLine("An error occurred: " + ex.Message);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine("An error occurred: " + ex.Message);
            }
        }
    }
}

我在上面的代码中添加了 try-catch 方法来处理发送 Web 请求时发生的异常。

结果： enter image description here

上一个：VB.net HttpWebRequest 超时

下一个：错误：请求已中止：无法创建 SSL/TLS 安全通道
