Question

我构建了一个功能，其目的是模拟真实浏览器的客户浏览网站，提交表单并从该网站接收结果。这是我的代码：

var cookieContainer = new CookieContainer();
using (var handler = new HttpClientHandler() { CookieContainer = cookieContainer })

using (var client = new HttpClient(handler))
{
    handler.Proxy = new WebProxy("127.0.0.1", 8888); //Allow Fiddler
    var response = client.PostAsync(baseAddress, null).Result;
    var cookies = response.Headers.GetValues("Set-Cookie").ToList();
    var sessionCookie = cookies[0];
    sessionCookie = sessionCookie.Split(';')[0];
    var sessionId = sessionCookie.Replace("ASP.NET_SessionId=", "");
    cookieContainer.Add(baseAddress, new Cookie("ASP.NET_SessionId", sessionId, "/"));
    client.DefaultRequestHeaders.Add("User-Agent", 
      "Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.115 Safari/537.36");
    client.DefaultRequestHeaders.AcceptEncoding.Add(new StringWithQualityHeaderValue("gzip"));
    client.DefaultRequestHeaders.AcceptEncoding.Add(new StringWithQualityHeaderValue("deflate"));
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("*/*"));
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    client.DefaultRequestHeaders.Add("X-Requested-With", "XMLHttpRequest");
    client.DefaultRequestHeaders.Add("Referer", "http://");
    client.DefaultRequestHeaders.Add("Accept-Language", "en-US,en;q=0.8,he;q=0.6");
    client.DefaultRequestHeaders.Add("Origin", "http://");
    client.DefaultRequestHeaders.Connection.Add("keep-alive");
    client.DefaultRequestHeaders.Add("Connection", "open");

    var values = new Dictionary<string, string>
    {
        ...
    };

    var content = new StringContent(JsonConvert.SerializeObject(values, new KeyValuePairConverter()), Encoding.UTF8, "application/json");

    response = client.PostAsync("http://", content).Result;                        
        //Thread.Sleep(milliseconds);
    client.DefaultRequestHeaders.Accept.Clear();
    //IEnumerable<Cookie> responseCookies = cookieContainer.GetCookies(baseAddress).Cast<Cookie>();
    //foreach (Cookie cookie in responseCookies)
    //{
    //    cookieContainer.Add(cookie);
    //}
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/html"));
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xhtml+xml"));
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("image/webp"));
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("image/apng"));
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("*/*"));
    client.DefaultRequestHeaders.Add("Upgrade-Insecure-Requests", "1");
    ***response = client.GetAsync("http://").Result;***
    client.DefaultRequestHeaders.Accept.Clear();
}

当我从我的VS 2017以dibug模式运行此代码时 - 它运行完美！发布到我的iis8服务器后，我得到了这个回复：

<HTML>
<head>
<script>
Challenge=;
ChallengeId=;
GenericErrorMessageCookies="Cookies must be enabled in order to view this page.";
</script>
<script>
function test(var1)
{
    var var_str=""+Challenge;
    var var_arr=var_str.split("");
    var LastDig=var_arr.reverse()[0];
    var minDig=var_arr.sort()[0];
    var subvar1 = (2 * (var_arr[2]))+(var_arr[1]*1);
    var subvar2 = (2 * var_arr[2])+var_arr[1];
    var my_pow=Math.pow(((var_arr[0]*1)+2),var_arr[1]);
    var x=(var1*3+subvar1)*1;
    var y=Math.cos(Math.PI*subvar2);
    var answer=x*y;
    answer-=my_pow*1;
    answer+=(minDig*1)-(LastDig*1);
    answer=answer+subvar2;
    return answer;
}
</script>
<script>
client = null;
if (window.XMLHttpRequest)
{
    var client=new XMLHttpRequest();
}
else
{
    if (window.ActiveXObject)
    {
        client = new ActiveXObject('MSXML2.XMLHTTP.3.0');
    };
}
if (!((!!client)&&(!!Math.pow)&&(!!Math.cos)&&(!![].sort)&&(!![].reverse)))
{
    document.write("Not all needed JavaScript methods are supported.<BR>");

}
else
{
    client.onreadystatechange  = function()
    {
        if(client.readyState  == 4)
        {
            var MyCookie=client.getResponseHeader("X-AA-Cookie-Value");
            if ((MyCookie == null) || (MyCookie==""))
            {
                document.write(client.responseText);
                return;
            }

            var cookieName = MyCookie.split('=')[0];
            if (document.cookie.indexOf(cookieName)==-1)
            {
                document.write(GenericErrorMessageCookies);
                return;
            }
            window.location.reload(true);
        }
    };
    y=test(Challenge);
    client.open("POST",window.location,true);
    client.setRequestHeader('X-AA-Challenge-ID', ChallengeId);
    client.setRequestHeader('X-AA-Challenge-Result',y);
    client.setRequestHeader('X-AA-Challenge',Challenge);
    client.setRequestHeader('Content-Type' , 'text/plain');
    client.send();
}
</script>
</head>
<body>
<noscript>JavaScript must be enabled in order to view this page.</noscript>
</body>
</HTML>

到目前为止我做了什么： 1.我使用来自我的localhost和生产服务器的fiddler来比较我的http请求 - 它们是相同的。我检查了我的iis网站是否设置使用cookies。我没有在服务器上找到cookie文件，而不是localhost来比较它们 - 我没有找到它们，也不知道它是否相关。

你能想到导致原因/解决方案的任何原因吗？

C＃HttpClient + Cookiecontainer适用于localhost失败的生产
