laravel处理文件的操作

#1 辅助函数storage_path()和public_path()

storage_path()和public_path()这两个辅助函数返回storage和public目录的完整路径。

storage_path()辅助函数返回的storage目录的完整路径，其实是php artisan storage:link生成的链接地址。

$path = 'articles';
return [
    storage_path($path),
    public_path($path),
];
//output
//[
//    "/home/vagrant/code/top/storage/articles",
//    "/home/vagrant/code/top/public/articles"
//]

#2 遍历文件的函数

files 方法返回指定目录下的所有文件的数组。allFiles 方法返回指定目录下包含子目录的所有文件的数组;

console下无法遍历public下面的文件夹，只能遍历storage的

$path = 'article';
//返回 SplFileInfo 对象的数组
$fileList1 = File::allfiles(Storage::disk('public')->path($path));

//返回storage下相对路径的数组，要转为绝对路径，用Storage::disk('public')->path($file)
$fileList2 = Storage::disk('public')->allFiles($path);

#3 综合实例

项目中有一个需求，业务部门提供 姓名+身份证号.pdf 的学历复印件，需要批量导入到员工的学历附件中

    /**
     * 批量导入逻辑
     * @param $path 放在storage里面的目录
     */
    public function import($path)
    {
        $files = Storage::disk('public')->allFiles($path);
        collect($files)
            ->each(function ($file, $key) {
                // import/education/李百川+440111199001011111.pdf
                $this->output->writeln("{$key}、开始导入{$file}..");
                $basename = basename($file);
                $fileInfo = explode('.', $basename);
                //$suffix = $fileInfo[1];
                $filename = $fileInfo[0];
                $empInfo = explode('+', $filename);
                if (count($empInfo) >= 2) {
                    $employee = Employee::query()
                        ->where('idCard', $empInfo[1])
                        ->first();
                    if ($employee) {
                        $education = $employee->educationList()->orderByDesc('graduateDate')->first();
                        if ($education && $education->media_count) {
                            $this->output->writeln("{$key}、{$file}已经导入过了！");
                            return;
                        }

                        if ($education && $education->media_count == 0) {
                            $education
                                ->addMedia(Storage::disk('public')->path($file))
                                ->toMediaCollection('education-pdf');
                            $this->output->success("{$key}、导入{$file}成功！");
                            return;
                        }
                    }
                }
                Log::channel('file_import')->error("{$file}导入失败！");
                $this->output->warning("{$key}、导入{$file}失败！");
            });
    }
