APS.NET MVC4生成解析二维码简单Demo
一、视图
@{ Layout = null; } DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Indextitle> <script src="~/Scripts/jquery-1.8.2.min.js">script> <script type="text/javascript"> $(function () { //生成 $('#createBtn').click(function () { createImage(); }); //解析 $('#analysisBtn').click(function () { analysisImage(); }); }); //生成二维码 function createImage() { var content = $('#content').val(); //ajax开始 $.post("/ORCode/GetORImage/", { "content": content }, function (data) { $('#imgDiv').empty(); $('#imgDiv').append(''); $("#ORImage").attr("src", data); }); //ajax结束 } //解析二维码 function analysisImage() { //获取图片名称 var imageUrl = $('#ORImage').attr("src"); var array = imageUrl.split('/'); var imageName = array[array.length - 1]; //如:123.jpg //ajax开始 $.post("/ORCode/GetORImageContent/", { "imageName": imageName }, function (data) { $('#ORCodeContent').empty(); $('#ORCodeContent').text(data); }); //ajax结束 } script> head> <body> <div style="text-align:center;"> <div> <textarea style="width:230px;height:120px;" id="content">textarea> <br /> <input id="createBtn" type="button" value="生成二维码" /> div> <div> <textarea style="width:230px;height:120px;" id="ORCodeContent">textarea> <br /> <input id="analysisBtn" type="button" value="解析二维码" /> div> <div style="margin-top:20px;" id="imgDiv"> div> div> body> html>
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 { ////// 生成二维码 /// /// 要编码的内容 /// 返回二维码位图 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; } /// /// 解析二维码 /// /// 要解析的二维码位图 /// 解析后的字符串 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; } } }
