Question

我想用HttpClient在C＃中复制以下代码。这是使用响应

中返回的相同cookie的php代码

if($cookies) {
        curl_setopt($ch, CURLOPT_COOKIEFILE,   dirname(__FILE__). '/cookies.txt');            
    } else {
        curl_setopt($ch, CURLOPT_COOKIEJAR,  dirname(__FILE__). '/cookies.txt');
    }

到目前为止，我所做的是

var returnedCookies = response.Headers.GetValues("Set-Cookie").ToList();

然后将其用作

string newCookie = string.Join(";",returnedCookies);
client.DefaultRequestHeaders.Add("Cookie", newCookie);

我不明白为什么这不起作用，我也试过使用CookieContainer，但它不起作用。有关此问题的任何帮助，或cURL C#使用的任何包装器或库都可以使用{I}}。

看看LibCurlNet https://github.com/pjquirk/libcurl.NET

它有一些非常好的示例，您实际上可以使用c＃

发送卷曲请求

public void sendCurlRequest(string url, bool post, string post_aata, bool cookies)
        {

        try
        {
            Curl.GlobalInit((int)CURLinitFlag.CURL_GLOBAL_ALL);

            Easy easy = new Easy();
            Easy.WriteFunction wf = new Easy.WriteFunction(OnWriteData);
            string writingData = string.Empty;
            easy.SetOpt(CURLoption.CURLOPT_URL, instagramUrl + url);


            easy.SetOpt(CURLoption.CURLOPT_FOLLOWLOCATION, 1);
            easy.SetOpt(CURLoption.CURLOPT_SSL_VERIFYPEER, 0);
            easy.SetOpt(CURLoption.CURLOPT_SSL_VERIFYHOST, 0);

            if (post)
            {
                easy.SetOpt(CURLoption.CURLOPT_POST, 1);
                File.WriteAllText("D:\\cookies\\post_data.txt", System.Web.HttpUtility.UrlEncode(post_aata));
                easy.SetOpt(CURLoption.CURLOPT_POSTFIELDS, post_aata);
            }

            if (cookies)
            {
                easy.SetOpt(CURLoption.CURLOPT_COOKIEFILE, "\cookies.txt");
            }
            else
            {
                easy.SetOpt(CURLoption.CURLOPT_COOKIEJAR, "cookies.txt");
            }
            var c = easy.Perform();
            int info = 0;
            CURLcode code = easy.GetInfo(CURLINFO.CURLINFO_RESPONSE_CODE, ref info);
            easy.Cleanup();

            Curl.GlobalCleanup();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }


    }
