七牛云：ckeditor JS SDK 结合 C#实现多图片上传。

成功了，搞了2天。分享一下经验。

首先是把官方的那个例子下载下来，然后照如下的方式修改。

其中tempValue是一个全局变量。

function savetoqiniu() {var uploader = Qiniu.uploader({
runtimes: "html5,flash,html4",
browse_button: "setfile",
    save_key:false,
//uptoken: qiniu_uptoken,
get_new_uptoken: true,
uptoken_func:function()
{
    tempValue=GetFileInfo();
    var res = $.ajax({
        type: "get",
        data: {
            key: tempValue
        },
        url: "/goods/CkeditorGetUploadToken/",
            async: false
    });
    return JSON.parse(res.responseText).uptoken;
},
//uptoken_url: "/goods/CkeditorGetUploadToken?key=" + tempValue,
domain: qiniu_bucket_domain,
container: "container",
max_file_size: "6mb",
filters: {
mime_types: [{
title: "Image files",
extensions: "jpeg,jpg,gif,png,wbmp"
}]
},
flash_swf_url: "./Moxie.swf",
max_retries: 3,
dragdrop: true,
drop_element: "container",
chunk_size: "4mb",
auto_start: false,
init: {
"PostInit": function() {
document.getElementById("uploadfile").onclick = function() {
//document.getElementById("setfile").style.display = "none";
uploader.start();
return false
}
},
"FilesAdded": function(up, files) {
plupload.each(files,
function(file) {
    document.getElementById("fileinfo").innerHTML += '<div id="' + file.id + '">' + file.name + "   (" + plupload.formatSize(file.size) + ")      <b></b><i></i></div><br>";
    //var key = Math.round(new Date().getTime() / 1000) + "_" + file.name;
    //keyQiniuUpload = key;
    //Test2();
})
},
"BeforeUpload": function (up, file) {        },
"UploadProgress": function(up, file) {
document.getElementById(file.id).getElementsByTagName("b")[0].innerHTML = "<span>" + file.percent + "%</span>"
},
"FileUploaded": function(up, file, info) {
var res = JSON.parse(info);
var sourceLink = qiniu_bucket_domain + "/" + res.key;
document.getElementById(file.id).getElementsByTagName("i")[0].innerHTML = sourceLink;
window.CKEDITOR.tools.callFunction(1, sourceLink, 'ok');
},
"Error": function(up, err, errTip) {},
"UploadComplete": function() {},
"Key": function(up, file) {
    var key = tempValue;
console.log(up);return key;
}
}
});
}

　　另外注意一点，就是KEY要传到后台去的，每次的KEY不同。下面是C#代码。

        /// <summary>
        /// 获得CKEDITOR上传凭证
        /// </summary>
        /// <returns></returns>
        public ActionResult CkeditorGetUploadToken(string key)
        {
           string s= UploadUtil.GetUploadToken("kmsfan",key);            if (!string.IsNullOrEmpty(s))
            {
                token token1 = new token();
                token1.uptoken = s;
                s = JsonConvert.SerializeObject(token1);
                //HttpContext.Response.ContentType = "text/plain";
                return Content(s);
                //return Json(new { uptoken = s});
            }
            return Json(new { IsSuccess = false });
        }

　　网上还没找到类似的解法，我这人不太善于表达，如果有需要的话，不懂的，请在底下留言。
