    public function uploadImg(){

tp5.1 获取原始上传文件名

打印一下上传的文件对象可以的得出，大致对象结构如下

object(thinkFile)#77 (13) {
  ["error":"thinkFile":private] =&gt; string(0) ""
  ["filename":protected] =&gt; string(14) "/tmp/phpkIAvIy"
  ["saveName":protected] =&gt; NULL
  ["rule":protected] =&gt; string(4) "date"
  ["validate":protected] =&gt; array(0) {
  }
  ["isTest":protected] =&gt; NULL
  ["info":protected] =&gt; array(5) {
    ["name"] =&gt; string(10) "ebrima.ttf"
    ["type"] =&gt; string(24) "application/octet-stream"
    ["tmp_name"] =&gt; string(14) "/tmp/phpkIAvIy"
    ["error"] =&gt; int(0)
    ["size"] =&gt; int(907232)
  }
  ["hash":protected] =&gt; array(0) {
  }
  ["pathName":"SplFileInfo":private] =&gt; string(14) "/tmp/phpkIAvIy"
  ["fileName":"SplFileInfo":private] =&gt; string(9) "phpkIAvIy"
  ["openMode":"SplFileObject":private] =&gt; string(1) "r"
  ["delimiter":"SplFileObject":private] =&gt; string(1) ","
  ["enclosure":"SplFileObject":private] =&gt; string(1) """
}
看这结构，访问权限是protected，如何获取呢?

获取方法:

对象->getInfo() 获取info属性

//对象->getInfo() 获取info属性,['name']  获取name的值
$file->getInfo()['name']

*表示所有支持的格式
<input type="file" accept="*" multiple="multiplt" />  
 
支持所有的图像(图片)文件
<input type="file" accept="image/*" multiple="multiplt" />   
 
上传Pdf
<input type="file" accept="application/msword, application/pdf" multiple="multiplt" />

ThinkPHP6实现下载文件

public function download()
{
    $famlePath = $_GET['resum'];
    $file_dir = ROOT_PATH . 'public' . DS . 'uploads' . '/' . "$famlePath";    // 下载文件存放目录
        
    // 检查文件是否存在
    if (! file_exists($file_dir) ) {
        $this->error('文件未找到');
    }else{
        // 打开文件
        $file1 = fopen($file_dir, "r");
        // 输入文件标签
        Header("Content-type: application/octet-stream");
        Header("Accept-Ranges: bytes");
        Header("Accept-Length:".filesize($file_dir));
        Header("Content-Disposition: attachment;filename=" . $file_dir);
        ob_clean();     // 重点！！！
        flush();        // 重点！！！！可以清除文件中多余的路径名以及解决乱码的问题：
        //输出文件内容
        //读取文件内容并直接输出到浏览器
        echo fread($file1, filesize($file_dir));
        fclose($file1);
        exit();
    }
}
