[英]Uploading a file (image) doesn't work on live server but works on dev
我無法解決這個問題。 以下代碼在我的本地計算機上可用,但是將站點上傳到服務器后,我似乎沒有在請求中收到文件。
這是我的ajax:
dialogUploadPhoto.find('form').submit(function(event) {
event.preventDefault();
$.ajax({
type: $(this).attr('method'),
url: $(this).attr('action'),
data: $(this).serializeForm(), // method below...
// data: formData,
processData: false,
contentType: false,
cache: false,
success: function(response) {
// The response has the correct date on my local server
dialogUploadPhoto.dialog( "close" );
},
error: function (xhr, desc, err){
// On the live server, the debugger hits
}
});
});
serializeForm方法只是一個將所有字段附加到FormData
實例的jquery方法:
$.fn.serializeForm = function() {
var form = $(this),
formData = new FormData();
var formParams = form.serializeArray();
$.each(form.find('input[type="file"]'), function(i, tag) {
$.each($(tag)[0].files, function(i, file) {
formData.append(tag.name, file);
});
});
$.each(formParams, function(i, val) {
formData.append(val.name, val.value);
});
return formData;
};
處理表單的symfony控制器方法如下所示:
/**
* Matches /admin/upload/foto
* @Route(
* "/upload/foto",
* options={"expose": true},
* name="admin_upload_foto")
* @Method({"POST"})
* @return JsonResponse
*/
public function upload_photo(
Request $request
) {
$response = new JsonResponse();
$newPhoto = new Fotos();
$photoForm = $this->createForm(PhotoType::class, $newPhoto);
$photoForm->handleRequest($request);
if ($photoForm->isSubmitted() && $photoForm->isValid()) {
// This part is hit on the dev server
} else if ($photoForm->isSubmitted()) {
// This part is hit on the live server!
// categorie contains no errors
$photoForm['categorie']->getErrors()->__toString());
// file contains an error: content-type is null;
$photoForm['file']->getErrors()->__toString());
$response->setStatusCode(400);
$response->setData(array("result" => 0, "errors" => $errors));
} else {
$response->setStatusCode(400);
$response->setData(array("result" => 0, "errors" => "Het foto-formulier is niet verzonden naar de server"));
}
return $response;
}
特定錯誤指出文件上傳文件的mime類型為null。 這是否意味着該文件永遠不會發送? 如果我這樣做: formData.getAll('file')
我可以看到文件實際上在包里。
在Chrome的網絡分析器中,我可以看到有效載荷確實包含該文件,也許它在途中丟失了?
根據要求,這是實時服務器上$ _FILES的var_dump
array(1) {
["photo"]=>
array(5) {
["name"]=>
array(1) {
["file"]=>
string(8) "test.png"
}
["type"]=>
array(1) {
["file"]=>
string(9) "image/png"
}
["tmp_name"]=>
array(1) {
["file"]=>
string(14) "/tmp/phpwy5m9y"
}
["error"]=>
array(1) {
["file"]=>
int(0)
}
["size"]=>
array(1) {
["file"]=>
int(25745)
}
}
}
任何幫助,將不勝感激
找到了解決方案,但我不得不放棄自動mime類型檢查。
根據symfony文檔,我不關心文件存儲為字符串。 symfony應該正確地“猜測”了啞劇類型檢查,但是針對啞劇類型的“斷言”規則不會選擇上載文件的啞劇類型。
我刪除了mimetype斷言規則,並使用手動擴展名檢查如下更改了我的處理方法:
$newPhoto = new Fotos();
$photoForm = $this->createForm(PhotoType::class, $newPhoto);
$photoForm->handleRequest($request);
// var_dump($photoForm->getData());
if ($photoForm->isSubmitted() && $photoForm->isValid()) {
// $file stores the uploaded PDF file
/* @var $file UploadedFile */
$file = $newPhoto->getFile();
$fileExtension = $file->guessClientExtension();
// var_dump($file->guessClientExtension());
if (($fileExtension === 'png' || $fileExtension === 'jpeg' || $fileExtension === 'jpg')) {
// Now I know the extension matches the type of files I want to handle
} else {
// Now I know the uploaded file is an invalid type
}
}
