C＃投递到浏览器发生故障，任何想法？ [英] C# Post to browser fails, any ideas?

问题描述

这是一个快速和肮脏的应用程序，只需要很短的时间工作。我不是一个开发商，所以请不要捶我。在ASP下code正常工作（秘密信息与example.com和ABC 123取代）。

This is a quick and dirty app that only needs to work for a short period. I'm not a developer so please don't hammer me. The following code in asp works fine (secret info replaced with example.com and abc 123).

我知道下面的是非常不好的做法，但是这仅仅是出于演示的目的：

I know the below is very bad practice, but this is just for demonstration purpose:

<form method="post" action="https://example.com/asppage.aspx" id="frm_main">
<input type="hidden" name="STATE" id="STATE" value="ABC" />
<input type="hidden" name="VALIDATION" id="VALIDATION" value="123/>
<input type="submit" name="refresh_progress" value="Check Status" id="refresh_progress" /></form>

不过，在我的C＃后同一code不工作：

However, the same code in my c# post doesn't work:

string PostData = "STATE=ABC&VALIDATION=123";
webBrowser1.Navigate("https://example.com/asppage.aspx", "_blank", Encoding.Default.GetBytes(PostData), "Content-Type: application/x-www-form-urlencoded\n\r");

在新的浏览器窗口弹出时，其默认asppage.aspx形式没有公布它的数据。

When the new browser window pops up, its the default asppage.aspx form with no data posted to it.

任何想法我做错了吗？

推荐答案

您正在给web浏览器的HTML表单，POST数据表单字段的名称和值的序列化格式，这是你所需要的把你的导航方法。

You're giving the webBrowser the html of the form, the POST data is a serialised format of the names and values of the form fields which is what you need to put in your Navigate method.

该POSTDATA需要在格式为：

The postdata needs to be in the format:

inputname1 =值1＆放大器; inputname2 =值2和放大器; inputname3 =值3

您还需要URI EN code中的字符串，包括内容类型：应用程序/ x-WWW的形式urlen codeD 作为第四个参数的方法调用。

You will also need to uri encode the string and include Content-Type: application/x-www-form-urlencoded as the fourth parameter in the method call.
