Question

我正在尝试从现有文件创建UploadedFile。但它没有成功上传，也没有显示任何错误。

这是我的代码

[ErrorException]                                                                                                                             
  Argument 2 passed to Illuminate\Database\Eloquent\Factory::{closure}() must be an instance of Faker\Provider\it_IT\PhoneNumber, array given

结果是

   $encoded_data = "This is a huge string";
   $filename = "tempFile";
   $handle = fopen($_SERVER['DOCUMENT_ROOT'].$filename, "a+")
   file_put_contents($_SERVER['DOCUMENT_ROOT'].$filename, $encoded_data);
   $file = new UploadedFile($_SERVER['DOCUMENT_ROOT'].$filename, $filename, null, filesize($_SERVER['DOCUMENT_ROOT'].$filename));
   var_dump($file->getClientSize());
   var_dump($file->getError());
   var_dump($file->isValid());
   var_dump(is_uploaded_file($file));

我确信tempFile存在于文档根目录中！

is_uploaded_file()会检查该文件是否已实际上传，因此无法使用您的代码，因为文件尚未上传。这就是isValid()也返回false的原因，因为它使用is_file_uploaded()来检查文件。一旦这样说，UploadedFile确实有一个$ test参数，如果设置为true，将使isValid()不检查文件是否实际上传。这用于测试，其中没有实际上传文件。您可以将此参数设置为true，然后isValid()将为您的文件返回true。这是一个黑客，但也许是你需要的

Symfony UploadedFile没有上传
