Question

我从网络上找到了下面的php文件，在我用角度4设计了一个Web应用程序之前，它工作得很好，在上传之前必须将照片裁剪掉。裁剪图像后，将裁剪后的图像保存为base64格式，现在我的问题是我如何配置当前的php脚本以将base64图像转换为真实图像

if ($_SERVER['REQUEST_METHOD'] !== 'POST') {
  echo json_encode(array('status' => false));
  exit;
}

$path = '../myapp/img_folder/';

if (isset($_FILES['file'])) {
  $originalName = $_FILES['file']['name'];
  $ext = '.'.pathinfo($originalName, PATHINFO_EXTENSION);
  $generatedName = md5($_FILES['file']['tmp_name']).$ext;
  $filePath = $path.$generatedName;

  if (!is_writable($path)) {
    echo json_encode(array(
      'status' => false,
      'msg'    => 'Destination directory not writable.'
    ));
    exit;
  }

  if (move_uploaded_file($_FILES['file']['tmp_name'], $filePath)) {
    echo json_encode(array(
      'status'        => true,
      'originalName'  => $originalName,
      'generatedName' => $generatedName
    ));
  }
}
else {
  echo json_encode(
    array('status' => false, 'msg' => 'No file uploaded.')
  );
  exit;
}

这是您的问题的解决方案。经过测试并可以正常工作。

$encoded = "encoded---text---here===";
$file = fopen("mypicture.png", "w"); //(you can put jpg, png or any other extension)
fwrite($file, base64_decode($encoded));
fclose($file);

将base64转换为真实图像并保存在php文件夹中
