高分求thinkphp中设置xheditor图片上传详细步骤。。。

Posted 2023-05-09

本人对JS一窍不通。。。希望能说简单一些。。。
从图像中如何出现“上传”按钮，如何调用upImgUrl，如何配置upload.php开始说起，感谢万分。
网上找了那些都是配置upload.php，并没有说如何调用“上传”按钮upImgUrl，我一点都不懂JS额。。。初学。。。

先在页面上面配置获取百度配置文件地址：window.UEDITOR_CONFIG.serverUrl = xx;

后面的就是服务器端了

使用文件选择器在图像 UI 元素中设置图片

【中文标题】使用文件选择器在图像 UI 元素中设置图片

【英文标题】：setting picture in image UI element using file picker

【发布时间】：2013-05-21 09:56:30

【问题描述】：

在我的应用程序中，用户可以从设备内存（即平板电脑内存或桌面本地驱动器）设置配置文件图片并将其上传到服务器。 我使用了文件选择器，以便用户可以选择一张图片并将其设置为个人资料图片，但问题是图片没有粘在 Image 元素上。 我的代码：

 private async void filePicker()
        
            FileOpenPicker openPicker = new FileOpenPicker();
            openPicker.ViewMode = PickerViewMode.Thumbnail;
            openPicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
            openPicker.FileTypeFilter.Add(".jpg");
            openPicker.FileTypeFilter.Add(".jpeg");
            openPicker.FileTypeFilter.Add(".png");

            StorageFile file = await openPicker.PickSingleFileAsync();
            if (file != null)
            

                String filePath = file.Path;
                System.Diagnostics.Debug.WriteLine(filePath);

                Uri uri = new Uri(filePath, UriKind.Relative);
                profilePicture.Source = new BitmapImage(uri);
            
        

        internal bool EnsureUnsnapped()
        
            // FilePicker APIs will not work if the application is in a snapped state.
            // If an app wants to show a FilePicker while snapped, it must attempt to unsnap first
            bool unsnapped = ((ApplicationView.Value != ApplicationViewState.Snapped) || ApplicationView.TryUnsnap());
            if (!unsnapped)
            
                //NotifyUser("Cannot unsnap the sample.", NotifyType.StatusMessage);
            

            return unsnapped;
        

我得到的文件路径是这个

filePath=C:\Users\Prateek\Pictures\IMG_0137.JPG

我不知道出了什么问题。

【参考方案1】：

我不确定这是否能解决问题，这是我设置图像源时所做的。

使用位图图像作为图像源

BitmapImage bitmapimage = new BitmapImage();
StorageFile file = await openPicker.PickSingleFileAsync();
var stream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
await bitmapimage.SetSourceAsync(stream);
profilePicture.Source = bitmapImage;

【参考方案2】：

我用过这段代码……

        var picker = new Windows.Storage.Pickers.FileOpenPicker();
        picker.ViewMode = Windows.Storage.Pickers.PickerViewMode.Thumbnail;
        picker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.PicturesLibrary;
        picker.FileTypeFilter.Add(".jpg");
        picker.FileTypeFilter.Add(".jpeg");
        picker.FileTypeFilter.Add(".png");

        Windows.Storage.StorageFile file = await picker.PickSingleFileAsync();
        if (file != null)
        
            this.textBlock.Text = 
                "File Path: " + file.Path + Environment.NewLine + 
                "File Name: " + file.Name;

            try
            
                var stream = await file.OpenReadAsync();
                var imageSource = new BitmapImage();
                await imageSource.SetSourceAsync(stream);

                this.image.Source = imageSource;
            
            catch (Exception ex)
            
                this.textBlock.Text = ex.ToString();
            
        
        else
        
            this.textBlock.Text = "Operation cancelled.";
