HTMLAgilityPack POST /w HTTPClient
正在尝试解析因 post 响应而加载的网页。但它不起作用我想我错过了一些东西但我不确定是什么...
HTML 代码
<input type="submit" name="ctl00$plhBodyArea$btnAccept" value="Accept" id="plhBodyArea_btnAccept">
<div class="aspNetHidden">

我的代码
var baseAddress1 = new Uri("http://app.alea.gov/Community/wfSexOffenderSearch.aspx");
using (var client = new HttpClient() { BaseAddress = baseAddress1 })
{
var loaded = client.GetAsync(baseAddress1).Result;
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(loaded.Content.ReadAsStringAsync().Result);
var viewState = doc.DocumentNode.SelectSingleNode("//input[@id='__VIEWSTATEGENERATOR']");
var eventValid = doc.DocumentNode.SelectSingleNode("//input[@id='__EVENTVALIDATION']");
var viewStateid = doc.DocumentNode.SelectSingleNode("//input[@id='__VIEWSTATE']");
string vsg = viewState.Attributes["value"].Value;
string ev = eventValid.Attributes["value"].Value;
string vsid = viewStateid.Attributes["value"].Value;
var content = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("__VIEWSTATE", vsid),
new KeyValuePair<string, string>("__VIEWSTATEGENERATOR", vsg),
new KeyValuePair<string, string>("__EVENTVALIDATION", ev),
new KeyValuePair<string, string>("ctl00%24plhBodyArea%24btnAccept", "Accept")
});
Console.WriteLine(content.ReadAsStringAsync().Result);
var result = client.PostAsync("http://app.alea.gov/Community/wfSexOffenderSearch.aspx", content).Result;
result.EnsureSuccessStatusCode();
File.WriteAllText("result.html", result.Content.ReadAsStringAsync().Result);
}
所以是的，我发送了 post 响应所需的大部分信息，但结果页面不是下一页，但仍然是相同的登录页面。
我是不是漏掉了什么？没有与我的代码执行相关的错误，只是结果不符合预期。没有饼干丢失或任何东西，所以不可能。
ctl00%24plhBodyArea%24btnAccept
不是正确的字段名称...它实际上是 $ 而不是 chrome 默认情况下将输出更改为 %24 抱歉没有注意到...
正在尝试解析因 post 响应而加载的网页。但它不起作用我想我错过了一些东西但我不确定是什么...
HTML 代码
<input type="submit" name="ctl00$plhBodyArea$btnAccept" value="Accept" id="plhBodyArea_btnAccept">
<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATEGENERATOR" id="__VIEWSTATEGENERATOR" value="9373CF0E">
<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="feTZ9oqpykfw9OnH.... more characters">
</div>
<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="yawbftCbDoV0i4ULGUh4Lh... shortten">
</div>
所以这是 chrome 开发人员的 HAR

我的代码
var baseAddress1 = new Uri("http://app.alea.gov/Community/wfSexOffenderSearch.aspx");
using (var client = new HttpClient() { BaseAddress = baseAddress1 })
{
var loaded = client.GetAsync(baseAddress1).Result;
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(loaded.Content.ReadAsStringAsync().Result);
var viewState = doc.DocumentNode.SelectSingleNode("//input[@id='__VIEWSTATEGENERATOR']");
var eventValid = doc.DocumentNode.SelectSingleNode("//input[@id='__EVENTVALIDATION']");
var viewStateid = doc.DocumentNode.SelectSingleNode("//input[@id='__VIEWSTATE']");
string vsg = viewState.Attributes["value"].Value;
string ev = eventValid.Attributes["value"].Value;
string vsid = viewStateid.Attributes["value"].Value;
var content = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("__VIEWSTATE", vsid),
new KeyValuePair<string, string>("__VIEWSTATEGENERATOR", vsg),
new KeyValuePair<string, string>("__EVENTVALIDATION", ev),
new KeyValuePair<string, string>("ctl00%24plhBodyArea%24btnAccept", "Accept")
});
Console.WriteLine(content.ReadAsStringAsync().Result);
var result = client.PostAsync("http://app.alea.gov/Community/wfSexOffenderSearch.aspx", content).Result;
result.EnsureSuccessStatusCode();
File.WriteAllText("result.html", result.Content.ReadAsStringAsync().Result);
}
所以是的，我发送了 post 响应所需的大部分信息，但结果页面不是下一页，但仍然是相同的登录页面。
我是不是漏掉了什么？没有与我的代码执行相关的错误，只是结果不符合预期。没有饼干丢失或任何东西，所以不可能。
ctl00%24plhBodyArea%24btnAccept
不是正确的字段名称...它实际上是 $ 而不是 chrome 默认情况下将输出更改为 %24 抱歉没有注意到...
