解决了困扰一周的问题
用了webupload，生成的是base64格式的
<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
<link media="all" rel="stylesheet" href="css/AlloyClip.css" type="text/css" />
<style type="text/css">
.clip, .clip2{
width: 500px;
height: 400px;
margin: 10px;
float: left;
}
h2{
text-align: center;
}
.footer{
clear: both;
margin-top: 600px;
text-align: center;
font-size: 14px;
color: #888;
line-height: 22px;
}
.footer a{
color: #888;
text-decoration:none;
}
</style>
</head>
<body>
<div class="clip"></div>
图片：<img src="" alt="" id="img1">
<!--<div class="clip2"></div>-->
<script type="text/javascript" src="js/alloyimage.js"></script>
<script type="text/javascript" src="js/alloyclip.min.js"></script>
<script type="text/javascript">
new $AC(".clip", 120, 120, 0).ok(function(base64, aiObj){
console.log(typeof(base64));
document.getElementById("img1").src=base64;
//aiObj.saveFile("AlloyCliped.jpg", 0.8);
});
</script>
</body>
</html>
然后项目是.net mvc获取这个并且存入数据库或者存入文件夹。
1.sql数据库字段varchar(8000)都不够，字段改成二进制的
2.上传有时候进不了后台，因为我的上传是ajax传的 data类型是"text"
<script type="text/javascript">
new $AC(".clip", 120, 120, 0).ok(function(base64, aiObj){
//console.log(base64);
document.getElementById("img1").src = base64;var bs4 = base64.substring(22);
console.log(bs4);
//aiObj.saveFile("AlloyCliped.jpg", 0.8);
$("#ceshi").click(function () {
$.ajax({
url: "/Clip/getbase",
type: "POST",
async: false,
xhrFields: { withCredentials: true },
dataType: "text",
data:{imgbase:bs4},
success:function(data){
console("成功："+data);
},
error:function(data){
console("失败："+data);
}
});
});
});
</script>原因是 public ActionResult getbase(string imgbase)
括号里面用对类型
3.我还得继续做项目，直接看代码吧，嘿嘿
public ActionResult getbase(string imgbase)
{
ClipBase64 cb = new ClipBase64();
cb.imageID = 5;
// byte[] base64 这个是byte的
// string ceshibase 这个是string 的
//cb.ceshibase = imgbase;
Encoding.Default.GetBytes(imgbase);
byte[] imgbyte = System.Convert.FromBase64String(imgbase);
//MemoryStream ms = new MemoryStream(imgbyte, 0, imgbase.Length);
//第一种可以这样
//System.IO.File.WriteAllBytes(@"E:\test\1.jpg", imgbyte);
//第二种
MemoryStream ms = new MemoryStream(imgbyte);
FileStream fs = new FileStream(@"E:\test\1.jpg", FileMode.Create);
ms.WriteTo(fs);
ms.Close();
fs.Close();
//int result = cm.clipImg(cb);
//if (result > 0)
//{
// ViewData["msg"] = "成功";
//}
//else
//{
// ViewData["msg"] = "失败";
//}
return View();
}
