当我尝试在控制器端通过ajax传递pdf时 file_get_content（）会出现这样的错误
file_get_contents(): Filename cannot be empty
我的输出如下： -
Illuminate\Http\UploadedFile Object(
[test:Symfony\Component\HttpFoundation\File\UploadedFile:private] =>
[originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 2017-playing-rules.pdf
[mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => application/octet-stream
[size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0
[error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 1
[hashName:protected] =>
[pathName:SplFileInfo:private] =>
[fileName:SplFileInfo:private] =>
）
这里“[pathName：SplFileInfo：private] =＆gt;”给出null响应，该响应应具有我上传文件的临时路径。
这是我的ajax电话： -
$('#formAddLeague').on('success.form.bv', function(e) {
e.preventDefault();
var formData = new FormData(this);
$.ajax({
url:'{{ url('restoreleague') }}',
data:formData,
type:'post',
dataType:'json',
cache: false,
contentType: false,
processData: false,
success: function(data)
{
$('#loader').hide();
if(data.key == 1)
{
notify('League has been updated Successfully.','blackgloss');
}
}
});
});
在控制器中我使用了以下内容： -
$import_rule = $request->file('importRule');
这是我的控制器： -
public function restore(Request $request)
{
$league_id = $request->get('hiddenLeagueId');
$import_rule = $request->file('importRule');
$league_rule_url = $request->get('txtLeagueRule');
$objLeague = League::find($league_id);
if (!empty($import_rule)) {
$originalName = $import_rule->getClientOriginalName();
$ruleFileName = pathinfo($originalName, PATHINFO_FILENAME) . '.' . pathinfo($originalName, PATHINFO_EXTENSION);
$s3 = Storage::disk('s3');
$filePath = 'league_rules/' . $ruleFileName;
if ($s3->put($filePath, file_get_contents($import_rule) , 'public'))
{
$ruleURL = $s3->url($filePath);
$objLeague->league_rules = $ruleURL;
$objLeague->rules_filename = $ruleFileName;
}
}
else
if (!empty($league_rule_url))
{
$checkExtension = pathinfo($league_rule_url, PATHINFO_EXTENSION);
if ($checkExtension != 'pdf')
{
$msg = "The selected url extension is not valid.";
return $msg;
}
else
{
$objLeague->league_rules = $league_rule_url;
}
}
$objLeague->league_name = $request->get('txtLeagueName');
$objLeague->league_email = $request->get('txtLeagueEmail');
$objLeague->league_phone = $this->replacePhoneNumber($request->get('leagueContactNo'));
$objLeague->league_info = $request->get('txtLeagueInfo');
$objLeague->level_id = $request->get('txtLevel');
$objLeague->age_required = $request->get('txtMinRequiredAge');
$objLeague->league_website = $request->get('leagueWebsite');
$objLeague->save();
$response['key'] = 1;
return $response;
}
这是我的表单： -
