C＃类型＆QUOT的HttpWebRequest的;应用程序/ x-WWW的形式urlen codeD＆QUOT; - 如何发送'和;'字符内容的身体吗？ [英] C# HttpWebRequest of type "application/x-www-form-urlencoded" - how to send '&' character in content body?

问题描述

我写在C＃中一个很小的API连接应用程序。

I'm writing a small API-connected application in C#.

我连接到其具有需要很长的串，日历（ICS）文件的内容的方法的API。

I connect to a API which has a method that takes a long string, the contents of a calendar(ics) file.

我做的是这样的：

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(URL);
request.Method = "POST";
request.AllowAutoRedirect = false;
request.CookieContainer = my_cookie_container;
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
request.ContentType = "application/x-www-form-urlencoded";

string iCalStr = GetCalendarAsString();

string strNew = "&uploadfile=true&file=" + iCalStr;

using (StreamWriter stOut = new StreamWriter(request.GetRequestStream(), System.Text.Encoding.ASCII))
 {
     stOut.Write(strNew);
     stOut.Close();
 }

这似乎工作的伟大，直到我在我的日历中添加一些特定的HTML。

This seems to work great, until I add some specific HTML in my calendar.

如果我有一个'和; NBSP在我的日历（或类似）服务器只获取的所有数据到某个地方'和;' - 点，所以我假设'和;'使它看起来像什么这点属于一个新的参数后？

If I have a '&nbsp' somewhere in my calendar (or similar) the server only gets all the data up to the '&'-point, so I'm assuming the '&' makes it look like anything after this point belongs to a new parameter?

我该如何解决这个问题？

How can I fix this?

推荐答案

由于您的内容类型为应用程序/ x-WWW的形式urlen codeD 你马上需要连接code中的POST体，尤其是如果它包含像＆放个字符; 这有一个形式特殊的意义。

Since your content-type is application/x-www-form-urlencoded you'll need to encode the POST body, especially if it contains characters like & which have special meaning in a form.

试用写入之前，通过你的字符串，通过 HttpUtility.UrlEn code 请求流。

Try passing your string through HttpUtility.UrlEncode before writing it to the request stream.
