CKEDITOR 文件上传错误请求 400 错误

Question

我正在使用带有文件浏览器和文件管理器插件的 ckEditor。当我配置 CKeditor 时我想要实现的目标我能够浏览某个文件夹中的文件..但是当我尝试通过它上传文件时我收到错误 400 Bad Request 可能是我需要做什么？

以下是我的代码

[HttpPost]
  CKEDITOR.replace('content_editor',{
            customConfig: '/assets/back/dist/plugins/ckeditor/config.js',
            "imageBrowser_listUrl" : "/webmaster/files/browser"
        });

        CKEDITOR.on('fileUploadRequest', function (evt) {
        
  var fileLoader = evt.data.fileLoader,
        formData = new FormData(),
        xhr = fileLoader.xhr;

    xhr.open( 'PUT', fileLoader.uploadUrl, true );
    formData.append( 'upload', fileLoader.file, fileLoader.fileName );
    fileLoader.xhr.send( formData );

    // Prevented the default behavior.
    evt.stop();
} );

请求处理程序 C# ASP.NET 核心 3.1

 public async Task<IActionResult> UploadFromEditor([FromForm]IFormFile upload)
        {
            if (upload.Length <= 0) return null;
            if (!upload.IsImage())
            {
                var NotImageMessage = "please choose a picture";
                dynamic NotImage = JsonConvert.DeserializeObject("{ 'uploaded': 0, 'error': { 'message': \"" + NotImageMessage + "\"}}");
                return Json(NotImage);
            }

            var fileName = Guid.NewGuid() + Path.GetExtension(upload.FileName).ToLower();

            Image image = Image.FromStream(upload.OpenReadStream());
            int width = image.Width;
            int height = image.Height;
            if ((width > 750) || (height > 500))
            {
                var DimensionErrorMessage = "Custom Message for error";
                dynamic stuff = JsonConvert.DeserializeObject("{ 'uploaded': 0, 'error': { 'message': \"" + DimensionErrorMessage + "\"}}");
                return Json(stuff);
            }

            if (upload.Length > 500 * 1024)
            {
                var LengthErrorMessage = "Custom Message for error";
                dynamic stuff = JsonConvert.DeserializeObject("{ 'uploaded': 0, 'error': { 'message': \"" + LengthErrorMessage + "\"}}");
                return Json(stuff);
            }

            var path = Path.Combine(
                Directory.GetCurrentDirectory(), "wwwroot/uploads/images/conten_images",
                fileName);

            using (var stream = new FileStream(path, FileMode.Create))
            {
                upload.CopyTo(stream);

            }

            var url = $"{"/uploads/images/CKEditorImages/"}{fileName}";
            var successMessage = "image is uploaded successfully";
            dynamic success = await Task.Run(() => JsonConvert.DeserializeObject("{ 'uploaded': 1,'fileName': \"" + fileName + "\",'url': \"" + url + "\", 'error': { 'message': \"" + successMessage + "\"}}"));
            return Json(success);
        }

额外的插件代码：

CKEDITOR.editorConfig = function( config ) {
    config.filebrowserBrowseUrl = '/assets/back/dist/ckeditor/plugins/imagebrowser/browser/browser.html'
    config.filebrowserUploadUrl = '/webmaster/files/UploadFromEditor';
    config.extraPlugins = 'filetools';
    config.extraPlugins = 'uploadimage';
    config.extraPlugins = 'popup';
    config.extraPlugins = 'imagebrowser';
    config.filebrowserUploadMethod = 'xhr';
    
    
};

根据您的测试请求的详细信息，您似乎配置并启用了防伪令牌验证。如果JavaScript客户端没有set/include请求中的token，会导致400 Bad Request错误。

要修复它，正如我在评论中提到的，我们可以将 IgnoreAntiforgeryToken 属性应用于操作方法 UploadFromEditor 以跳过防伪标记验证。

或者在请求头中设置token，使请求能够通过防伪token验证。
