php - 从 Android webview 相机拍摄的图像未保存到文件夹

问题描述

我有这个我在https://github.com/上获得的 Smart Webview，这很棒。作为 Android 新手开发人员，我一直在尝试解决这个问题。如果我从电话目录中选择图像并发送到后端（PHP）；一切正常：图像被移动到上传文件夹；但是如果我使用 Android 相机拍照，图像永远不会发送到文件夹，但图像的名称会保存到数据库中。

图片上传的MainActivity

   $imgType = $_FILES['photo']['type'];
  

  $imgExt = strtolower(pathinfo($imgFile,PATHINFO_EXTENSION)); // get image extension

// valid image extensions
  $valid_extensions = array('jpeg', 'jpg', 'png'); // image extensions
  $vid_extensions = array('avi', 'mp4', 'wav','3gp','AAC','flv','wmv'); // video extensions
  $aud_extensions = array('mp3'); // audio extensions

   // rename uploading image
    $userpic = rand(1000,1000000).".".$imgExt;
    if(!empty($imgFile)){
    $pic = $userpic;
    }else{
        $pic = '';
    }
    
   if(!empty($imgFile) && in_array($imgExt, $valid_extensions)){
