Post,GET中文传值乱码问题
正常情况下,url传值前对中文进行编码,然后接受页面作对应的解码。
即使不对含有中文的url编码,接受页面也能正确获取参数值,因为默认编码为utf-8。(POST传值包含中文也正常)
项目中有时webconfig设置<globalization requestEncoding="gb2312"/>,或者页面上设置gb2312编码方式,若编码与解码不统一,很容易造成乱码的问题。
utf-8编码
GET传值:
Request.QueryString在获取时使用gb2312解码,导致出现乱码。
解决方法:
Request.RawUrl 获取原url地址(未使用gb2312解码前),然后使用utf-8解码.
Request.Url.Query 获取原url地址参数信息(未使用gb2312解码前),同上。
POST传值:
<html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> <form action="WebForm1.aspx" method="post"> <input type="text" name="username" /> <br /> <input type="text" name="address" /> <input type="submit" /> <br /> <br /> <a href="WebForm1.aspx?username=测试&&address=1">跳转</a> </form> </body> </html>
WebForm1代码
protected void Page_Load(object sender, EventArgs e) { string username = Request.Form["username"]; string address = Request.Form["address"]; Response.Write("username :" + username + "<br/>"); Response.Write("address :" + address + "<br/>"); Response.Write("<hr/>"); Response.Write("Request.ContentEncoding.EncodingName :" + Request.ContentEncoding.EncodingName + "<br/>"); //注意长度 Response.Write("Request.ContentLength :" + Request.ContentLength); Response.Write("<hr/>"); //GET传值内容长度为0 if (Request.ContentLength != 0) { byte[] bytes = new byte[Request.InputStream.Length]; Request.InputStream.Read(bytes, 0, bytes.Length); string input = System.Text.Encoding.Default.GetString(bytes);
Response.Write("Request.InputStream :" + input + "<br/>"); //获取键值 string[] param = input.Split('&'); System.Collections.Generic.Dictionary<string, string> dic = new Dictionary<string, string>(); foreach (string s in param) { dic.Add(s.Split('=')[0], HttpUtility.UrlDecode(s.Split('=')[1])); } foreach (var s in dic.Keys) { Response.Write(string.Format("{0} :{1}<br/>", s, dic[s])); } } }
输出:
