C#如何使用geckofx浏览器浏览帖子数据? [英] C# How to Navigate with post data using the geckofx browser?

问题描述

我在Visual Studio 2013中使用C#，并与geckofx浏览器一起使用，我需要使用POST进行导航. Navigate方法告诉我我需要一个MimeInputStream，使用起来很直观.我面临的问题是如何初始化它? MimeInputStream没有构造函数.我发现下面的代码可以编译，除了不能将GeckoMIMEInputStream强制转换为MimeInputStream的部分.我的代码是:

I'm using C# with Visual Studio 2013, working with the geckofx browser, and I need to Navigate using POST. The Navigate method is telling me I need a MimeInputStream, which is intuitive to use. The problem I'm facing with that is how to initialize it? MimeInputStream doesn't have a constructor. I found that the following code compiles, except the part where it can't cast the GeckoMIMEInputStream into a MimeInputStream like that. My code is:

string dataString = string.Format("username={0}&pwd={1}, Username, Password);

GeckoMIMEInputStream postData = new GeckoMIMEInputStream();
postData.AddHeader("Content-Type", "application/x-www-form-urlencoded");
postData.AddContentLength = true;
postData.SetData(dataString);

myGeckoFXBrowser.Navigate("javascript:void(document.getElementById('formname').submit())", GeckoLoadFlags.ReplaceHistory, null, postData);

推荐答案

感谢汤姆，这使我朝正确的方向前进；这是我的生产代码:

Thanks Tom, that sent me to the right direction; here is my production code:

protected void NavigateWithPostData(string URLToGoTo, string POSTData)
{
    var postData = MimeInputStream.Create();
    postData.AddHeader("Content-Type", "application/x-www-form-urlencoded");
    postData.AddContentLength = true;
    postData.SetData(POSTData);

    mainBrowser.Navigate(URLToGoTo, GeckoLoadFlags.BypassCache, mainBrowser.Url.AbsoluteUri, postData);
}

然后像这样使用它:

    string dataString = string.Format("SMNTH={0}&SDAY={1}&SYR={2}", workingDate.Month, workingDate.Day, workingDate.Year);

    NavigateWithPostData("http://<yourapp>", dataString);
