用ajax提交一组表单，里面包含一个图片，
原来不用ajax提交的时候可以成功保存到数据库，
但因为上传前要压缩图片，所以改为ajax提交，ajax请求成功发送，但不能保存到数据库，
我想可能是控制器里面的代码需要修改，但不知怎么改，下面是代码。
ps:压缩图片用到了localResizeIMG插件。https://github.com/think2011/localResizeIMG
下面是用ajax提交表单的视图：

});
$("#submit").click(function (rst) {
$.ajax({

url: "article/",
dataType: 'json',
cache: false,
data: {
title: $("#title").val(),
content: $("#content").val(),
photo: rst.formData
}
}).done(function (msg) {
alert("done: " + msg);
}).fail(function (jqXHR, textStatus) {
alert("fail: " + textStatus);
});
});
});
</script>
</body>
</html>
下面是原来没用ajax时候的控制器，可以成功保存到数据库，现在不知怎么改。
public function store(Requests\StoreArticleRequest $request)
{
$article = new Article($request->except('photo'));
$article -> user_id = \Auth::id();
$file = $request->file('photo');
$destinationPath = 'uploads/';
$extension = $file->getClientOriginalExtension();
$fileName = \Auth::user()->id . '_' . time() . '.' . $extension;
$file->move($destinationPath, $fileName);
$article -> photo = '/'.$destinationPath.$fileName;
$article->save();
return redirect()->action('ArticleController@show', ['id' => $article->id]);
}下面是StoreArticleRequest
public function rules()
{
return [
'title'=>'required',
'content'=>'required',
'photo'=>'image'
];
}
save前你先dd下$article数据看看csrf，ajax提交的时候不要忘。
