dd($request->all()); gives back empty array
提问by chloealee
I am trying to upload a photo from my Laravel 5 app to be stored in AWS. I am using the Postman REST client to test. When I upload a photo, the request returns an empty array. Does anyone know why this might be? Here's the code for my Avatar Controller:
我正在尝试从我的 Laravel 5 应用程序上传照片以存储在 AWS 中。我正在使用 Postman REST 客户端进行测试。当我上传照片时，请求返回一个空数组。有谁知道为什么会这样？这是我的头像控制器的代码：
class AvatarController extends Controller
{
public function __construct(AWS $aws)
{
$this->aws = $aws;
}
/**
* Store a new avatar for a user.
* POST northstar.com/users/{id}/avatar
*/
public function store(User $user, Request $request)
{
dd($request->all());
// dd($request->file('photo'));
$file = $request->file('photo');
// $file = Request::file('photo');
// $file = Input::file('photo');
$v = Validator::make(
$request->all(),
['photo' => 'required|image|mimes:jpeg,jpg|max:8000']
);
if($v->fails())
return Response::json(['error' => $v->errors()]);
$filename = $this->aws->storeImage('avatars', $file);
// Save filename to User model
$user->avatar = $filename;
$user->save();
// Respond to user with success
return response()->json('Photo uploaded!', 200);
}
}

Found the answer - looks like there was an issue with my headers in Postman. I had both Accept application/json and Content-Type application/json. Once I removed Content-Type, all is fixed. Thanks!
找到了答案 - 看起来我在 Postman 中的标题有问题。我有 Accept application/json 和 Content-Type application/json。一旦我删除了 Content-Type，一切就都解决了。谢谢！

Bit late to the party, but might be usefull for others:
My problem was that the Content-Typeheader value was application/jsonwhile the actual payload was form data. Changing the header to application/x-www-form-urlencodedfixed the issue.
参加聚会有点晚，但可能对其他人有用：我的问题是Content-Type标题值是application/json实际有效负载是表单数据。更改标题以application/x-www-form-urlencoded解决问题。

You might want to test that the JSON is valid
您可能想要测试 JSON 是否有效
$data = $request->all();
if(empty($data)) {
$data = json_decode($request->getContent());
$data = json_decode($data);
if(is_null($data)) {
return response()->json("Not valid json", 400);
}
}

The same issue on postman, while using PUT/PATCH method directly. One possible solution is to send your PUT/PATCH request as a POST, but include proper _methodin the request body along with other parameters.
邮递员也有同样的问题，直接使用 PUT/PATCH 方法。一种可能的解决方案是将您的 PUT/PATCH 请求作为 POST 发送，但在请求正文中包含适当的_method以及其他参数。
_method: PUT
_method: PUT
Hope this helps
希望这可以帮助

Just want to add where i made a mistake. When sending POST request with Postman, you also have to make sure the json is correct.
只是想补充一下我犯错的地方。使用 Postman 发送 POST 请求时，您还必须确保 json 是正确的。
// invalid json (notice the ending comma)
{
"akey":"aval",
"nkey": "bval",
}
//valid json (no ending comma)
{
"akey":"aval",
"nkey": "bval"
}

Try dd($request), dd($_REQUEST), dd($request->files).
