C# 从 POST 请求中获取不带标头的内容

Question

我的网站向我的程序发送了回复。这是它的样子：

这是一个 POST 请求，将一些用户数据从 Web 浏览器发送到程序。我的目标只是从上面获取 URI 编码的数据。目前我的低效方法是使用以下代码：

 string[] splitted = rawResponse.Split(new char[] { '\r', '\n' });
 //int result = 0;
 string aa = null;

 for (int i = 0; i < splitted.Length; i++)
 {
    if (splitted[i].Contains("%"))
    {
        aa = aa + splitted[i];
    }
 }

 string s = System.Uri.UnescapeDataString(aa);
 Console.WriteLine(s);

其中 rawResponse 就是上面的请求。打印出来的结果是这样的：

{"name":"Adola","telp":"","agen":"pribadi","alamatagen":"","hp":"","email":"Adola@gmail.com","userid":"ABCDEFG","password":"123456","pcidses":"ABCDEFG","pcidperm":"1497742211491","imgsrc":"","capcode":"dsiauh","ckperm":"","cknw":"","ckcd1":"","ckcd2":""}

问题是当请求标头（不是内容）包含“%”时，它会给我一个错误，例如。 GET /%USER%/12865。我如何有效地毫无问题地获取内容。谢谢！

我建议你跳过标题，直接照顾身体。如果您的源对象不提供直接访问正文的方法，请使用此代码：

string[] splitted = rawResponse.Split(new char[] { '\r', '\n' });
string aa = null;
if (splitted[splitted.Length-1].Contains("%"))
{
    aa = aa + splitted[splitted.Length-1];
}

string s = System.Uri.UnescapeDataString(aa);
Console.WriteLine(s);
