Answers:
首先实例化CKEditor时注册您的自定义浏览器/上传器。您可以为图像浏览器和普通文件浏览器指定不同的URL。
<script type="text/javascript">
CKEDITOR.replace('content', {
filebrowserBrowseUrl : '/browser/browse/type/all',
filebrowserUploadUrl : '/browser/upload/type/all',
filebrowserImageBrowseUrl : '/browser/browse/type/image',
filebrowserImageUploadUrl : '/browser/upload/type/image',
filebrowserWindowWidth : 800,
filebrowserWindowHeight : 500
});
</script>
您的自定义代码将收到一个名为CKEditorFuncNum的GET参数。保存它-这是您的回调函数。假设您将其放入$callback。
当某人选择一个文件时，运行此JavaScript通知CKEditor选择了哪个文件：
window.opener.CKEDITOR.tools.callFunction(<?php echo $callback; ?>,url)
其中“ url”是他们选择的文件的URL。可选的第三个参数可以是要在标准警报对话框中显示的文本，例如“非法文件”或其他内容。如果第三个参数是错误消息，则将url设置为空字符串。
CKEditor的“上载”选项卡将在PHP的“上载”字段中提交文件，该文件将转到$ _FILES ['upload']。CKEditor希望服务器输出的是完整的JavaScript块：
$output = '<html><body><script type="text/javascript">window.parent.CKEDITOR.tools.callFunction('.$callback.', "'.$url.'","'.$msg.'");</script></body></html>';
echo $output;
同样，您需要为其提供该回调参数，文件的URL以及可选的消息。如果消息为空字符串，则不会显示任何内容。如果消息错误，则url应该为空字符串。
官方CKEditor文档尚不完整，但是，如果您遵循上述内容，它将像冠军一样工作。
我已经发布了一个有关将旧的FCKEditor中可用的FileBrowser集成到CKEditor中的小教程。
http://www.mixedwaves.com/2010/02/integrating-fckeditor-filemanager-in-ckeditor/
它包含执行此操作的分步说明，非常简单。希望对此有所帮助的人对本教程有所帮助。
我本人只是经历了学习过程。我想通了，但是我同意文档的编写对我来说有点吓人。对我而言，最大的“ aha”时刻是我了解到，对于浏览而言，CKeditor所做的只是打开一个新窗口并在url中提供一些参数。它允许您添加其他参数，但是建议您需要在值上使用encodeURIComponent（）。
我称浏览器和上传器
CKEDITOR.replace( 'body',
{
filebrowserBrowseUrl: 'browse.php?type=Images&dir=' +
encodeURIComponent('content/images'),
filebrowserUploadUrl: 'upload.php?type=Files&dir=' +
encodeURIComponent('content/images')
}
对于浏览器，在打开的窗口（browse.php）中，使用php＆js提供选项列表，然后在提供的onclick处理程序上调用带有两个参数的CKeditor函数，即所选择图像的url / path和网址中由CKeditor提供的CKEditorFuncNum：
function myOnclickHandler(){
//..
window.opener.CKEDITOR.tools.callFunction(<?php echo $_GET['CKEditorFuncNum']; ?>, pathToImage);
window.close();
}
同样，上传者只需调用您提供的url，例如upload.php，然后再次提供$ _GET ['CKEditorFuncNum']。目标是iframe，因此，从$ _FILES保存文件后，您将您的反馈传递给CKeditor，如下所示：
$funcNum = $_GET['CKEditorFuncNum'];
exit("<script>window.parent.CKEDITOR.tools.callFunction($funcNum, '$filePath', '$errorMessage');</script>");
下面是一个易于理解的自定义浏览器脚本。尽管它不允许用户在服务器中浏览，但是它允许您在调用浏览器时指示从哪个目录提取图像文件。
都是相当基本的编码，因此它应该可以在所有相对较新的浏览器中使用。
CKeditor只会使用提供的网址打开一个新窗口
/*
in CKeditor **use encodeURIComponent()** to add dir param to the filebrowserBrowseUrl property
Replace content/images with directory where your images are housed.
*/
CKEDITOR.replace( 'editor1', {
filebrowserBrowseUrl: '**browse.php**?type=Images&dir=' + encodeURIComponent('content/images'),
filebrowserUploadUrl: 'upload.php?type=Files&dir=' + encodeURIComponent('content/images')
});

我花了一段时间试图找出答案，这就是我所做的。我已经很简单地分解了它，因为这就是我所需要的。
在您的ckeditor文本区域正下方，输入这样的上传文件>>>>
<form action="welcomeeditupload.asp" method="post" name="deletechecked">
<div align="center">
<br />
<br />
<label></label>
<textarea class="ckeditor" cols="80" id="editor1" name="editor1" rows="10"><%=(rslegschedule.Fields.Item("welcomevar").Value)%></textarea>
<script type="text/javascript">
//<![CDATA[
CKEDITOR.replace( 'editor1',
{
filebrowserUploadUrl : 'updateimagedone.asp'
});
//]]>
</script>
<br />
<br />
<br />
<input type="submit" value="Update">
</div>
</form>
'，然后添加您的上传文件，这是我用ASP编写的文件。如果您使用的是PHP等，只需将ASP替换为您的上传脚本，但要确保页面输出的内容相同。
<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<%
if Request("CKEditorFuncNum")=1 then
Set Upload = Server.CreateObject("Persits.Upload")
Upload.OverwriteFiles = False
Upload.SetMaxSize 5000000, True
Upload.CodePage = 65001
On Error Resume Next
Upload.Save "d:\hosting\belaullach\senate\legislation"
Dim picture
For Each File in Upload.Files
Ext = UCase(Right(File.Path, 3))
If Ext <> "JPG" Then
If Ext <> "BMP" Then
Response.Write "File " & File.Path & " is not a .jpg or .bmp file." & "<BR>"
Response.write "You can only upload .jpg or .bmp files." & "<BR>" & "<BR>"
End if
Else
File.SaveAs Server.MapPath(("/senate/legislation") & "/" & File.fileName)
f1=File.fileName
End If
Next
End if
fnm="/senate/legislation/"&f1
imgop = "<html><body><script type=""text/javascript"">window.parent.CKEDITOR.tools.callFunction('1','"&fnm&"');</script></body></html>;"
'imgop="callFunction('1','"&fnm&"',"");"
Response.write imgop
%>
这是我使用的方法。这非常简单，并且效果很好。
在CK编辑器的根目录中，有一个名为config.js的文件。
我添加了这个（您不需要querystring的东西，这仅用于我们的文件管理器）。我还对显示的默认按钮进行了外观设计和更改：
CKEDITOR.editorConfig = function(config) {
config.skin = 'v2';
config.startupFocus = false;
config.filebrowserBrowseUrl = '/admin/content/filemanager.aspx?path=Userfiles/File&editor=FCK';
config.filebrowserImageBrowseUrl = '/admin/content/filemanager.aspx?type=Image&path=Userfiles/Image&editor=FCK';
config.toolbar_Full =
[
['Source', '-', 'Preview', '-'],
['Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Print', 'SpellChecker'], //, 'Scayt'
['Undo', 'Redo', '-', 'Find', 'Replace', '-', 'SelectAll', 'RemoveFormat'],
'/',
['Bold', 'Italic', 'Underline', 'Strike', '-', 'Subscript', 'Superscript'],
['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', 'Blockquote'],
['JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock'],
['Link', 'Unlink', 'Anchor'],
['Image', 'Flash', 'Table', 'HorizontalRule', 'SpecialChar'],
'/',
['Styles', 'Format', 'Templates'],
['Maximize', 'ShowBlocks']
];
};
然后，我们的文件管理器将其称为：
opener.SetUrl('somefilename');
在zerokspot上的一篇名为CKEditor 3.0中的 “ 自定义文件浏览器回调 ”的文章对此进行了处理。最相关的部分引用如下：
因此，选择文件后，在文件浏览器中要做的就是使用正确的回调编号（通常为1）和所选文件的URL调用此代码：
window.opener.CKEDITOR.tools.callFunction(CKEditorFuncNum,url);对于快速上传器，此过程非常相似。最初，我认为编辑器可能正在侦听200 HTTP返回代码，并且可能会查看一些标头字段或类似内容以确定上传文件的位置，但是随后-通过一些Firebug监视-我注意到所有发生的事情上传后为以下代码：
<script type="text/javascript">
window.parent.CKEDITOR.tools.callFunction(CKEditorFuncNum,url, errorMessage);</script>如果上传失败，请将设置
errorMessage为一些非零长度的字符串并清空url，反之则成功。
首先实例化CKEditor时注册您的自定义浏览器/上传器。
<script type="text/javascript">
CKEDITOR.replace('content', {
filebrowserUploadUrl: "Upload File Url",//http://localhost/phpwork/test/ckFileUpload.php
filebrowserWindowWidth : 800,
filebrowserWindowHeight : 500
});
</script>
上传文件代码（ckFileUpload.php）并将上传文件放在项目的根目录下。

经过大量的自定义文件上传的研发之后，最终编辑器的文档还不清楚，我终于找到了这种解决方案。它对我有用，我希望对其他人也有帮助。
对于那些想了解Servlet / JSP实现的人，这里是您的实现方法...我还将在下面解释uploadimage。
1）首先，请确保已将filebrowser和uploadimage变量添加到config.js文件中。也让您在plugins文件夹中也具有uploadimage和filebrowser文件夹。
2）这部分是让我绊倒的地方：
Ckeditor网站文档说您需要使用以下两种方法：
function getUrlParam( paramName ) {
var reParam = new RegExp( '(?:[\?&]|&)' + paramName + '=([^&]+)', 'i' );
var match = window.location.search.match( reParam );
return ( match && match.length > 1 ) ? match[1] : null;
}
function returnFileUrl() {
var funcNum = getUrlParam( 'CKEditorFuncNum' );
var fileUrl = 'https://patiliyo.com/wp-content/uploads/2017/07/ruyada-kedi-gormek.jpg';
window.opener.CKEDITOR.tools.callFunction( funcNum, fileUrl );
window.close();
}
他们没有提到的是这些方法必须位于不同的页面上，而不是您从中单击浏览服务器按钮的页面上。
因此，如果您已在页面editor.jsp中初始化了ckeditor，则需要在文件filebrowser.jsp中创建一个文件浏览器（带有基本的html / css / javascript）。
editor.jsp（您所需要的只是在script标记中）当您单击浏览服务器按钮时，此页面将在迷你窗口中打开filebrowser.jsp。
CKEDITOR.replace( 'editor', {
filebrowserBrowseUrl: '../filebrowser.jsp', //jsp page with jquery to call servlet and get image files to view
filebrowserUploadUrl: '../UploadImage', //servlet
});
filebrowser.jsp（是您构建的自定义文件浏览器，其中将包含上述方法）
<head>
<script src="../../ckeditor/ckeditor.js"></script>
</head>
<body>
<script>
function getUrlParam( paramName ) {
var reParam = new RegExp( '(?:[\?&]|&)' + paramName + '=([^&]+)', 'i' );
var match = window.location.search.match( reParam );
return ( match && match.length > 1 ) ? match[1] : null;
}
function returnFileUrl() {
var funcNum = getUrlParam( 'CKEditorFuncNum' );
var fileUrl = 'https://patiliyo.com/wp-content/uploads/2017/07/ruyada-kedi-gormek.jpg';
window.opener.CKEDITOR.tools.callFunction( funcNum, fileUrl );
window.close();
}
//when this window opens it will load all the images which you send from the FileBrowser Servlet.
getImages();
function getImages(){
$.get("../FileBrowser", function(responseJson) {
//do something with responseJson (like create <img> tags and update the src attributes)
});
}
//you call this function and pass 'fileUrl' when user clicks on an image that you loaded into this window from a servlet
returnFileUrl();
</script>
</body>
3）FileBrowser Servlet
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Images i = new Images();
List<ImageObject> images = i.getImages(); //get images from your database or some cloud service or whatever (easier if they are in a url ready format)
String json = new Gson().toJson(images);
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(json);
}
4）UploadImage Servlet
返回ckeditor的config.js文件，并添加以下行：
//https://docs.ckeditor.com/ckeditor4/latest/guide/dev_file_upload.html
config.uploadUrl = '/UploadImage';
然后，您还可以拖放文件：
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Images i = new Images();
//do whatever you usually do to upload your image to your server (in my case i uploaded to google cloud storage and saved the url in a database.
//Now this part is important. You need to return the response in json format. And it has to look like this:
// https://docs.ckeditor.com/ckeditor4/latest/guide/dev_file_upload.html
// response must be in this format:
// {
// "uploaded": 1,
// "fileName": "example.png",
// "url": "https://www.cats.com/example.png"
// }
String image = "https://www.cats.com/example.png";
ImageObject objResponse = i.getCkEditorObjectResponse(image);
String json = new Gson().toJson(objResponse);
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(json);
}
}
那就是所有人。希望它能帮助某人。
