public function fileUpload(Request $request) {$this->validate($request, ['input_img' =>'必需|图像| mimes:jpeg,png,jpg,gif,svg|max:2048',]);if ($request->hasFile('input_img')) {$image = $request->file('input_img');$name = time().'.'.$image->getClientOriginalExtension();$destinationPath = public_path('/images');$image->move($destinationPath, $name);$this->save();return back()->with('success','图片上传成功');}}My controller code for upload file in laravel 5.4:
if ($request->hasFile('input_img')) {
if($request->file('input_img')->isValid()) {
try {
$file = $request->file('input_img');
$name = rand(11111, 99999) . '.' . $file->getClientOriginalExtension();
$request->file('input_img')->move("fotoupload", $name);

}
Image was successfully uploaded but the code threw an exception :
FileNotFoundException in MimeTypeGuesser.php line 123
The file is there any fault in my code or is it a bug in laravel 5.4, can anyone help me solve the problem ?
My view code:
<form enctype="multipart/form-data" method="post" action="{{url('admin/post/insert')}}">
{{ csrf_field() }}
<div class="form-group">
<label for="imageInput">File input</label>
<input data-preview="#preview" name="input_img" type="file" id="imageInput">
<img class="col-sm-6" id="preview" src="">
<p class="help-block">Example block-level help text here.</p>
</div>
<div class="form-group">
<label for="">submit</label>
<input class="form-control" type="submit">
</div>
</form>
