Ueditor implements custom conttoler requests or cross-origin requests, ueditorconttoler

UEditor is a WYSIWYG text web Editor developed by Baidu's FEX front-end R & D team. It is lightweight, customizable, and focuses on user experience. It is open source based on the MIT protocol, allow free use and modification of code. We often use it for website text editing. However, ueditor supports saving images under the root directory of the website by default. However, for websites, most of the time we need to save static resources to another server and separate them from the application server to increase the website performance.

This method is described below:

I,

Ueditor 1.4.2 + we recommend that you use a unique request address and use the GET parameter action to specify different request types. However, many users want to use their own upload addresses. The following provides a solution: because all ueditor requests obtain the request address through the getActionUrl method of the editor object, this method can be directly implemented by writing this section of js to a separate js, add the webpage, and put it after the js that references uditor. Example:

UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;UE.Editor.prototype.getActionUrl = function(action) {    if (action == 'uploadimage' || action == 'uploadscrawl' || action == 'uploadimage') {        return 'http://a.b.com/upload.php';    } else if (action == 'uploadvideo') {        return 'http://a.b.com/video.php';    } else {        return this._bkGetActionUrl.call(this, action);    }}

Action type and description

• Uploadimage: // The name of the action to be uploaded
• Uploadscrawl: // name of the action to upload the graffiti
• Uploadvideo: // action name of the video to be uploaded
• Uploadfile: // The action name of the video to be uploaded in the controller.
• Catchimage: // name of the action for capturing remote Images
• Listimage: // execute the action name to list Images
• Listfile: // execute the action name of the list file
  
  

Replace the returned address with your own controller address or cross-domain address. 2. Define the format of the returned value. Because ueditor uses ajax requests, the returned format is a json string. Format :{
"State": "SUCCESS ",
"Url": "upload/demo.jpg ",
"Title": "demo.jpg ",
"Original": "demo.jpg", "type": ". jpg", "size": "1024 "}
Here, type is the image type, size is the image size, and url is the accessible address of the image inserted into ueditor. We also have another way to know the returned format, in the default configuration of ueditor, you can check the format of the returned value after the image is uploaded successfully. Press f12 in the browser and click network-> response 3. The Chinese name of the image returns garbled characters. When the image name is Chinese, the returned results contain garbled characters, for example :???; Not even after UTF-8 encoding is configured. This is because ueditor is displayed in unicode mode during display. At this time, we need to convert the json string returned to the unicode format, as follows: (1) controller that receives the image:

Package com. gametech. controller; import java. io. file; import java. io. IOException; import java. util. iterator; import javax. servlet. http. httpServletRequest; import javax. servlet. http. httpServletResponse; import org. springframework. stereotype. controller; import org. springframework. web. bind. annotation. requestMapping; import org. springframework. web. bind. annotation. responseBody; import org. springframework. web. mul Tipart. multipartFile; import org. springframework. web. multipart. multipartHttpServletRequest; import org. springframework. web. multipart. commons. commonsMultipartResolver; import com. alibaba. fastjson.

(2) unicode Conversion Method

/*** Convert Chinese to Unicode Code * @ param str * @ return */public static String chinaToUnicode (String str) {String result = ""; for (int I = 0; I <str. length (); I ++) {int chr1 = (char) str. charAt (I); if (chr1> = 19968 & chr1 <= 171941) {// Chinese character range \ u4e00-\ u9fa5 (Chinese) result + = "\ u" + Integer. toHexString (chr1);} else {result + = str. charAt (I) ;}} return result ;}

OK.
