Question

这是JavaScript

function ChangeVol(id)
{
    document.form.selectFS_devId.value = id;
    document.form.selectFS_currentNameSpace.value = "";
    document.form.submit();
}
function ChangeEvsVol(id, vNodeId)
{
    document.form.selectFS_evsId.value = vNodeId;
    document.form.selectFS_currentNameSpace.value = "";
    ChangeVol(id);
}

document.form.selectFS_devId.value = "all"  
document.form.selectFS_evsId.value = "2"

这是我正在使用的当前C＃代码

Uri url = new Uri("https://mgr/app");
HttpWebRequest request = null;

ServicePointManager.ServerCertificateValidationCallback =
   ((sender, certificate, chain, sslPolicyErrors) => true);
CookieContainer cookieJar = new CookieContainer();

request = (HttpWebRequest)WebRequest.Create(url);
request.CookieContainer = cookieJar;
request.Method = "GET";
HttpStatusCode responseStatus;

using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
     responseStatus = response.StatusCode;
     url = request.Address;
}

if (responseStatus == HttpStatusCode.OK)
{
      UriBuilder urlBuilder = new UriBuilder(url);
      urlBuilder.Path = 
          urlBuilder.Path.Remove(urlBuilder.Path.LastIndexOf('/')) + 
          "/j_security_check";

      request = (HttpWebRequest)WebRequest.Create(urlBuilder.ToString());
      request.Referer = url.ToString();
      request.CookieContainer = cookieJar;
      request.Method = "POST";
      request.ContentType = "application/x-www-form-urlencoded";

      using (Stream requestStream = request.GetRequestStream())
      using (StreamWriter requestWriter = new StreamWriter(requestStream, Encoding.ASCII))
      {
           string postData = "j_username=user&j_password=user&submit=Send";
           requestWriter.Write(postData);
      }

      string responseContent = null;
      string myTargetString = "https://mgr/app/action/storage.VivolAction/eventsubmit_dopreparevivollist/ignored/f5/true";
      using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
      using (Stream responseStream = response.GetResponseStream())
      using (StreamReader responseReader = new StreamReader(responseStream))
      {
         responseContent = responseReader.ReadToEnd();
      }
      Console.WriteLine(responseContent);
      request = (HttpWebRequest)WebRequest.Create(myTargetString);
      request.Method = "GET";
      request.CookieContainer = cookieJar;
      using (HttpWebResponse responsedownload = (HttpWebResponse)request.GetResponse())
      using (Stream responseStream = responsedownload.GetResponseStream())
      using (StreamReader responseReader = new StreamReader(responseStream))
      {
            responseContent = responseReader.ReadToEnd();
      }
      Console.WriteLine(responseContent);

问题是字符串myTargetString没有加载javascript参数，如果我可以复制URL中的那些参数会很棒，如果没有，我需要做什么来提交像我上面的帖子请求中的那些在StreamWriter？

using (StreamWriter requestWriter = new StreamWriter(requestStream, Encoding.ASCII))
            {
                string postData = "j_username=user&j_password=user&submit=Send";
                requestWriter.Write(postData);
            }

我在网址中的含义可能是：

https://mgr/app/action/storage.VivolAction/eventsubmit_dopreparevivollist/ignored?&evsId=1&devId=all&currentpagenumberbottom=1&filtername=&currentpagenumber=1&quotaactionlink=/mgr/app/action/storage.VivolQuotaAction&ascending=true&currentpagesize=20&ignoreErrorMessages=true&pageindex=1&sortby=name&filterpath=

Fiddler向我提供了这个

我可以在其中看到electFS_devId=all和selectFS_evsId=2，我需要更改EVSID，但我不确定如何构建URL。是的我改变了cookie id

Answer 1

您的javascript只是在执行提交之前为表单上可能隐藏的字段设置表单值。您需要执行POST请求，方法与登录时相同。

查看HTML中表单标记的操作值，以确定提交数据的位置并将以下表单项放入postData：

selectFS_devId
selectFS_currentNameSpace
selectFS_evsId

您可以使用以下内容：

string postData = string.Format("selectFS_currentNameSpace={0}&selectFS_evsId={1}&selectFS_devId={2}", "", "2", "all");

看起来这会涉及到，因为它似乎使用selectFS_uniqueId进行某种形式的会话或事务跟踪，您可能必须首先执行GET操作，然后从表单中提取该值。另外，请注意您的提交位置与之前的j_security_check一样，不会与检索表单的GET（doprepare）进入POST（doprocess）的相同位置。

GET https://mgr/app/action/storage.SelectFileSystemAction/eventsubmit_doprepareselectfilesystem/ignored

POST https://mgr/app/action/storage.SelectFileSystemAction/eventsubmit_doprocessselectfilesystem/ignored

在这里再看一下你的帖子值。很明显，有一个命令发布了一个类（selectFS_action_class）和方法（selectFS_action_method），如果没有指定它们，可能什么都不会完成。

op=
&selectFS_devId=all
&selectFS_previous_template=
&selectFS_evsId=2
&selectFS_currentNameSpace=
&selectFS_action_class=storage.VivolAction
&selectFS_action_method=doPreparevivollist
&selectFS_uniqueId=13655b454e3951462f
&selectFS_dont_alter_current=false
&selectFS_disableReplicationTargets=true
&selectFS_disableReadCache=true
&selectFS_disableWorm=false
&selectFS_disableUnmounted=true

与其编写所有这些内容来模拟通过Web界面进行操作的用户，您是否已使用F5检查他们是否有可以调用的Web服务来执行此操作？

也许问题在于，这种形式的参数“j_username = user＆amp; j_password = user＆amp; submit = Send”是HTTP“GET”而非“POST”的参数，您可以尝试以这种方式获取参数。 C＃

var operacion = context.Request.Form[0] "POST"
var operacion = context.Request.Params[0];

或

Request.Querystring("parameterName") for "GET"

或在javascript中你可以使用$ _GET或$ _POST

我认为你的问题是渴望得到你所要求的。另外，您没有显示有关在浏览器中发布的任何代码。

好像你只想知道如何让表单发布工作......我注意到你没有设置contentlength属性......这可能与它有关。另外，看看这个“帖子”......
