二、控制器
using system;
using system.collections.generic;
using system.linq;
using system.web;
using system.web.mvc;
using common;
using system.drawing;
namespace qrcodedemo.controllers
{
public class orcodecontroller : controller
{
//
// get: /orcode/
public actionresult index()
{
return view();
}
[httppost]
public actionresult getorimage(string content)
{
//if (string.isnullorempty(content))
//{
// return content("");
//}
string timestr = datetime.now.tofiletime().tostring();
bitmap bitmap = qrcodeop.qrcodeencoderutil(content);
string filename = server.mappath("~") + "content\\images\\qrimages\\" + timestr + ".jpg";
bitmap.save(filename);//保存位图
string imageurl = "/content/images/qrimages/" + timestr + ".jpg";//显示图片
return content(imageurl);
}
[httppost]
public actionresult getorimagecontent(string imagename)
{
string fileurl = server.mappath("~") + "content\\images\\qrimages\\" + imagename;
bitmap bitmap = new bitmap(fileurl);
string content = qrcodeop.qrcodedecoderutil(bitmap);
return content(content);
}
}
}
三、二维码生成工具类
using system;
using system.collections.generic;
using system.linq;
using system.text;
using system.threading.tasks;
using thoughtworks.qrcode.codec;
using thoughtworks.qrcode.codec.data;
using system.drawing;
namespace common
{
public class qrcodeop
{
/// <summary>
/// 生成二维码
/// </summary>
/// <param name="qrcodecontent">要编码的内容</param>
/// <returns>返回二维码位图</returns>
public static bitmap qrcodeencoderutil(string qrcodecontent)
{
qrcodeencoder qrcodeencoder = new qrcodeencoder();
qrcodeencoder.qrcodeversion = 0;
bitmap img = qrcodeencoder.encode(qrcodecontent, encoding.utf8);//指定utf-8编码， 支持中文
return img;
}
/// <summary>
/// 解析二维码
/// </summary>
/// <param name="bitmap">要解析的二维码位图</param>
/// <returns>解析后的字符串</returns>
public static string qrcodedecoderutil(bitmap bitmap)
{
qrcodedecoder decoder = new qrcodedecoder();
string decodedstring = decoder.decode(new qrcodebitmapimage(bitmap), encoding.utf8);//指定utf-8编码， 支持中文
return decodedstring;
}
}
}
以上就是简单解析了aps.net mvc4下二维码的生成过程，希望对大家的学习有所帮助，制作属于自己的二维码。
