1.  数据结构

data() { 
    	item:[
    		file: { 
    			basename: "2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
    			extension: "pdf"
    			filename: "2021-04 JavaScript高级程序设计第4版(1)(1)"
    		}
    		link: "report-pdf/2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
    	]
    }

1.  前端点击删除按钮，传递参数

delPPT() { 
        let item = this.pitem
        console.log('item=', this.pitem)
        // 1.文件为basename: "2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
    	let deleteItem = item.file.basename
    	
    	// 2.文件为link: "report-pdf/2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
    	let deleteItem = item.link
        console.log(deleteItem)
        sendGetReq({ deleteItem}, '/api/common/delete-ppt', this.callback3);
        this.$refs['modal-delete-ppt'].hide()
    },

1.  后端接收参数并做删除处理

use Illuminate\Support\Facades\File;
     public function deletePpt(Request $request)
        { 
            print_r($request->input('deleteItem'));
    // 1.指定public文件夹, 传递的是"2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
            $filesInFolder = File::files(public_path(''));
            print_r($filesInFolder);
            $filesInFolder->delete($request->input('deleteItem'));
    
            $flagDeleted = !$filesInFolder->exists($request->input('deleteItem'));
            if ($flagDeleted)
                return [true, '删除成功'];
            else
                return [false, '删除失败'];
    
    // "message": "Call to a member function delete() on array",
    
    
    // 2.指定根文件夹，传递的是"2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
            $filesInFolder = File::files(public_path('new-game-online-report-pdf/'));
            print_r($filesInFolder);
            $filesInFolder->delete($request->input('deleteItem'));
    
            $flagDeleted = !$filesInFolder->exists($request->input('deleteItem'));
            if ($flagDeleted)
                return [true, '删除成功'];
            else
                return [false, '删除失败'];
    
    // "message": "Call to a member function delete() on array",
    
    // 3.指定根文件夹，传递的是 "report-pdf/2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
            $filesInFolder = File::files(public_path('new-game-online-report-pdf/'));
            print_r($filesInFolder);
            $filesInFolder->delete($request->input('deleteItem'));
            $flagDeleted = !$filesInFolder->exists($request->input('deleteItem'));
            if ($flagDeleted)
                return [true, '删除成功'];
            else
                return [false, '删除失败'];
    
    // "message": "Call to a member function delete() on array",
    
    // 4.指定public文件夹, 传递的是 "report-pdf/2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
    
            $filesInFolder = File::files(public_path(''));
            print_r($filesInFolder);
            $filesInFolder->delete($request->input('deleteItem'));
            $flagDeleted = !$filesInFolder->exists($request->input('deleteItem'));
            if ($flagDeleted)
                return [true, '删除成功'];
            else
                return [false, '删除失败'];
    
    // "message": "Call to a member function delete() on array",没拿到new-game-online-report-pdf/文件
    
    
    // 5.指定file，传递的是 "report-pdf/2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
            File::delete($request->input('deleteItem'));
            $flagDeleted = !File::exists($request->input('deleteItem'));
            if ($flagDeleted)
                return [true, '删除成功'];
            else
                return [false, '删除失败'];
    
    // 删除成功
    
    
    // 6. 指定storage，传递传递的是 "report-pdf/2021-04 JavaScript高级程序设计第4版(1)(1).pdf"
            Storage::delete($request->input('deleteItem'));
            $flagDeleted = !Storage::exists($request->input('deleteItem'));
            if ($flagDeleted)
                return [true, '删除成功'];
            else
                return [false, '删除失败'];
    
    // 删除成功，但刷新后文件仍存在
        }
