C＃：从Windows桌面应用程序打开浏览器并POST到URL
[英]C#: Open a browser and POST to a url from a windows desktop app
问题描述
I have a small WPF app (although I guess it doesn't really matter whether it's a wpf form or a webform app?) that I want to have launch a new browser window and POST to a specific url. 
我有一个小型的WPF应用程序（虽然我认为无论是wpf表单还是webform应用程序并不重要？）我想要启动一个新的浏览器窗口并POST到特定的URL。 I've been messing around with: 我一直在搞乱：
System.Diagnostics.Process.Start("http://myurl.com");
to launch the window but I don't think I can use the same process to actually post to a url...I've also experimented with HttpWebRequest but I would like the user to be able to use the app after I have posted to this url, not just show them the results...What can I look at to able to do something like this? 启动窗口，但我不认为我可以使用相同的过程实际发布到网址...我也尝试过HttpWebRequest但我希望用户能够在发布到我之后使用该应用程序这个网址，不只是向他们展示结果......我能看到什么才能做到这样的事情？

There is no direct way to do it. 没有直接的方法可以做到这一点。 What you could do is generate a HTML page with a form filled with the data you need to post, and a bit of javascript to post the page automatically when it is loaded. 您可以做的是生成一个HTML页面，其中的表单中填充了您需要发布的数据，以及一些javascript，以便在加载时自动发布页面。 Then you just have to open that page in the browser... 然后你只需要在浏览器中打开该页面......
The generated HTML could look like that : 生成的HTML可能如下所示：
<html>
<head>
<script language="Javascript">
function submitForm() {
var theForm = document.getElementById("theForm");
theForm.submit();
}
</script>
</head>
<body onload="submitForm()">
<form id="theForm" action="http://myurl.com" method="POST">
<input type="text" name="username" value="myusername"/>
<input type="password" name="password" value="mypassword"/>
</form>
</body>
</html>
If the page must be displayed in your application, load it in a WebBrowser control 如果必须在应用程序中显示该页面，请将其加载到WebBrowser控件中

请改用WebBrowser类 。

You can create a hidden WebBrowser control and do Navigate() (using the overload that allows you to specify the request method). 您可以创建隐藏的WebBrowser控件并执行Navigate() （使用允许您指定请求方法的重载）。 You will need to specify a "_blank" target frame to cause the navigation to happen in a new browser window. 您需要指定一个“_blank”目标框架，以便在新的浏览器窗口中进行导航。

There are multiple solutions, not sure which one would be the best for you... 有多种解决方案，不确定哪一种最适合您......
- Proceed with your original approach 继续您的原始方法
- Embed web browser control in your applicaiton as suggested in other answers 按照其他答案中的建议，在您的应用程序中嵌入Web浏览器控件
- Do everything programmatically "behind the scene" 以编程方式“在幕后”做所有事情

If you want to go with #1 - it is more tricky, since you need to control external application and different browsers would behave differently. 如果你想使用＃1 - 它更棘手，因为你需要控制外部应用程序，不同的浏览器会表现不同。
I've used "javascript:" protocol and the code below with IE as default browser when dealing with one "user-unfriendly" application. 在处理一个“用户不友好”的应用程序时，我使用了“javascript：”协议和IE下面的代码作为默认浏览器。 Please note that it's not "production-ready" code. 请注意，它不是“生产就绪”代码。 There is no error handling, user may shift focus away from launched browser, or use browser without "javascript:" protocol support etc. 没有错误处理，用户可能会将焦点从启动的浏览器转移，或使用没有“javascript：”协议支持等的浏览器。
static void Main()
{
Settings s = Settings.Default;
Process.Start(s.URL1);
Thread.Sleep(s.Delay1);
SendKeys.SendWait("%D");
Thread.Sleep(100);
SendKeys.SendWait(EncodeForSendKey(s.URL2));
SendKeys.SendWait("{ENTER}");
}
public static string EncodeForSendKey(string value)
{
StringBuilder sb = new StringBuilder(value);
sb.Replace("{", "{{}");
sb.Replace("}", "{}}");
sb.Replace("{{{}}", "{{}");
sb.Replace("[", "{[}");
sb.Replace("]", "{]}");
sb.Replace("(", "{(}");
sb.Replace(")", "{)}");
sb.Replace("+", "{+}");
sb.Replace("^", "{^}");
sb.Replace("%", "{%}");
sb.Replace("~", "{~}");
return sb.ToString();
}
- URL1: http://www.google.com URL1： http ： //www.google.com
- URL2: javascript:function x(){document.all.q.value='stackoverflow';document.forms[0].submit();} x(); URL2：javascript：function x（）{document.all.q.value ='stackoverflow'; document.forms [0] .submit（）;} x（）;
