ScrapySharp does not POST form

本文关键字：form POST not does ScrapySharp | 更新日期: 2024-06-14 06:39:53

我正在使用ScrapySharp在Maryland Case search web应用程序上发布一个搜索案件的表格。

使用Fiddler，我找到了表单名称和表单字段；然而，每次我发布时，它总是返回最初的搜索页面，而不是结果。

不确定我缺少了什么，请参阅下面的代码。

我们非常感谢您的帮助。

            string url = @"http://casesearch.courts.state.md.us/casesearch/processDisclaimer.jis?disclaimer=Y";
        ScrapingBrowser Browser = new ScrapingBrowser();
        Browser.AllowAutoRedirect = true;
        Browser.AllowMetaRedirect = true;
        WebPage PageResult = Browser.NavigateToPage(new Uri(url));
        PageWebForm form = PageResult.FindForm("inquiryForm");
        form["firstName"] = "";
        form["middleName"] = "";
        form["partyType"] = "";
        form["filingStart"] = "";
        form["filingEnd"] = "";
        form["action"] = "Search";
        form["company"] = "N";
        form["countyName"] = "MONTGOMERY COUNTY";
        form["courtSystem"] = "B";
        form["filingDate"] = "4/4/2016";
        form["lastName"] = "A";
        form["site"] = "CIVIL";
        form.Method = HttpVerb.Post;
        WebPage results = form.Submit();
        Console.WriteLine(results.ToString());

ScrapySharp does not POST form

您需要进行异步调用。

例如：

WebPage mainPage = await browser.NavigateToPageAsync(new Uri(url), HttpVerb.Get,"", "text/html; charset=UTF-8");
PageWebForm form = mainPage.FindFormById("some-form_id");

WebPage web = await Task.Run(() => form.Submit());//submit不是异步的，所以让我们强制它

试试这个：

form.FormFields.Where(f => f.Name == "countyName").FirstOrDefault().Value = "MONTGOMERY COUNTY";
