/// <summary> /// 圖片上傳 /// </summary> /// <param name="env"></param> /// <returns></returns> public async Task<IActionResult> UploadImageUrl([FromServices]IHostingEnvironment env) { // CKEditor提交的很重要的一個參數 string callback = Request.Query["CKEditorFuncNum"]; var form = Request.Form; var img = form.Files[0]; //獲取圖片 string fileName = img.FileName; var openReadStream = img.OpenReadStream(); byte[] buff = new byte[openReadStream.Length]; await openReadStream.ReadAsync(buff, 0, buff.Length); string filenameGuid = Guid.NewGuid().ToString(); var bowerPath = PathUtils.GetSavePath(filenameGuid, true) + ".jpg";//獲取到圖片保存的路徑，這邊根據自己的實現 var savePath = Path.Combine(env.WebRootPath, bowerPath); using (FileStream fs = new FileStream(savePath, FileMode.Create)) { await fs.WriteAsync(buff, 0, buff.Length); //服務器返回JavaScript腳本 string result = $"<script type=\"text/javascript\">window.parent.CKEDITOR.tools.callFunction(\"{callback}\", \"{"/"+bowerPath}\", \"\");</script>"; Response.ContentType = "text/html;charset=UTF-8"; return Content(result); } } |
6.注意
服務器返回需要加上這個，否則會遇到前端頁面不執行返回的JavaScript腳本的問題
|

|
Response.ContentType = "text/html;charset=UTF-8"; |
配置完成即可使用圖片上傳功能
