A 400 error is usually returned by ASP.NET if your request fails verification. This most often occurs if you make a POST request using AJAX, but forget to include the verification token that gets generated by the BeginForm HTML helper or the form tag helper

Hello . I want to upload a picture through CKeditor, but I have a 400 error. Thank you for guidance.
config file :
CKEDITOR.editorConfig = function (config) { // Define changes to default configuration here. For example: // config.uiColor = '#AADC6E'; config.contentsLangDirection = 'rtl'; config.language = 'fa'; config.filebrowserImageUploadUrl = './ImageUpload' ; config.toolbar = 'MyToolbar'; config.toolbar_MyToolbar = [ { name: 'document', items: ['Source', '-', 'Save', 'NewPage', 'DocProps', 'Preview', 'Print', '-', 'Templates'] }, { name: 'clipboard', items: ['Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Undo', 'Redo'] }, { name: 'editing', items: ['Find', 'Replace', '-', 'SelectAll', '-', 'SpellChecker', 'Scayt'] }, { name: 'forms', items: ['Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton', 'HiddenField'] }, { name: 'basicstyles', items: ['Bold', 'Italic', 'Underline', 'Strike', 'Subscript', 'Superscript', '-', 'RemoveFormat'] }, { name: 'links', items: ['Link', 'Unlink', 'Anchor'] }, { name: 'colors', items: ['TextColor', 'BGColor'] }, '/', { name: 'insert', items: ['Image', 'Flash', 'Table', 'HorizontalRule', 'Smiley', 'SpecialChar', 'PageBreak', 'Iframe'] }, { name: 'paragraph', items: ['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', '-', 'Blockquote', 'CreateDiv', '-', 'JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock', '-', 'BidiLtr', 'BidiRtl'] }, { name: 'styles', items: ['Styles', 'Format', 'Font', 'FontSize'] } ]; };view code :

More details on the verification token can be found here: https://www.learnrazorpages.com/security/request-verification. The post is about Razor Pages on .NET Core, but the principal is the same for MVC.

Thank you so much
I built an Area "Admin" and a Controller then in Index Action :
public IActionResult Index() { return View(); }and View Index :
<div class="container text-right dirrtl"> <div class="row"> <div class="col-md-8"> <textarea id="description" rows='7'></textarea> </div> </div> </div> @section scripts{ <script src="//cdn.ckeditor.com/4.11.4/standard/ckeditor.js"></script> <script> CKEDITOR.replace('description', { customConfig: '/js/Config.js' }); </script> }and Then my action UploadImage :
[HttpPost] [ValidateAntiForgeryToken] public IActionResult UploadImage(IFormFile upload, string CKEditorFuncNum, string CKEditor, string langCode) { if (upload.Length <= 0) return null; var fileName = Guid.NewGuid() + Path.GetExtension(upload.FileName).ToLower(); var path = Path.Combine( _hostingEnvironment.WebRootPath, "MyImages", fileName); using (var stream = new FileStream(path, FileMode.Create)) { upload.CopyTo(stream); } var url = $"{"/MyImages/"}{fileName}"; return Json(new { uploaded = true, url }); }and config.js :
CKEDITOR.editorConfig = function (config) { // Define changes to default configuration here. For example: // config.uiColor = '#AADC6E'; config.contentsLangDirection = 'rtl'; config.language = 'fa'; config.filebrowserImageUploadUrl = './uploadimage' ; config.toolbar = 'MyToolbar'; config.toolbar_MyToolbar = [ { name: 'document', items: ['Source', '-', 'Save', 'NewPage', 'DocProps', 'Preview', 'Print', '-', 'Templates'] }, { name: 'clipboard', items: ['Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Undo', 'Redo'] }, { name: 'editing', items: ['Find', 'Replace', '-', 'SelectAll', '-', 'SpellChecker', 'Scayt'] }, { name: 'forms', items: ['Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton', 'HiddenField'] }, { name: 'basicstyles', items: ['Bold', 'Italic', 'Underline', 'Strike', 'Subscript', 'Superscript', '-', 'RemoveFormat'] }, { name: 'links', items: ['Link', 'Unlink', 'Anchor'] }, { name: 'colors', items: ['TextColor', 'BGColor'] }, '/', { name: 'insert', items: ['Image', 'Flash', 'Table', 'HorizontalRule', 'Smiley', 'SpecialChar', 'PageBreak', 'Iframe'] }, { name: 'paragraph', items: ['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', '-', 'Blockquote', 'CreateDiv', '-', 'JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock', '-', 'BidiLtr', 'BidiRtl'] }, { name: 'styles', items: ['Styles', 'Format', 'Font', 'FontSize'] } ]; };All-Star

I still can't see any code for uploading the image. Are you using a jQuery $.post ?

yes
I have added these codes but it is not correct
in view:
@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf @functions{ public string GetAntiXsrfRequestToken() { return Xsrf.GetAndStoreTokens(Context).RequestToken; } }and in config.js :
CKEDITOR.editorConfig = function (config) { // Define changes to default configuration here. For example: // config.uiColor = '#AADC6E'; config.contentsLangDirection = 'rtl'; config.language = 'fa'; config.filebrowserImageUploadUrl = 'uploadImage'; config.toolbar = 'MyToolbar'; config.fileTools_requestHeaders = { 'X-CSRFToken': '{{ @GetAntiXsrfRequestToken() }}' },All-Star

In ASP.NET Core, the name of the header should be RequestVerificationToken, unless you have specified something else in Startup.

One question is, photos are now stored in the myimage folder and their address is in ckeditor
If I want to save the URL of the ckeditor to the server, what should I do?
Should I search the entire text for the name of the photo and save any image in the database?
