好的我有一个小问题。

我希望用户能够将图像上传到公共/徽标文件夹，并在div中显示该图像。

但是我在尝试上传时遇到了这两个错误：

JS：

function submitImage() {
    var fd = new FormData($("#upload_form")[0]);
    fd.append('img', $('#img'));
    $.ajax({
        url: 'business',
        data: fd,
        dataType: 'json',
        async: false,
        type: 'post',
        processData: false,
        contentType: false,
        success: function(data) {
            $("#image").attr("src", data.url);
            $('.naviga').append('<div class="alert alert-success">Image Uploaded!<div>');
            $(".alert-success").fadeOut(5000);
        },
        error: function(data) {
            var errors = data.responseJSON; //this will get the errors response data.
            //show them somewhere in the markup
            //e.g
            var errorsHtml = '<div class="alert alert-danger">';
            errorsHtml += errors.img[0]; //showing only the first error.
            errorsHtml += '</div>';
            $('.naviga').append('<div class="alert alert-danger">File type not supported! Use files with image extension only!<div>'); //appending to a <div id="form-errors">
            $(".alert-danger").fadeOut(5000);
        }
    });
}

控制器：

public function image(Requests\ImageRequest $request) {
    if($request->hasFile('img'))
    {
        $image = Input::file('img');
        $filename = time() . '.' . $image->getClientOriginalExtension();
        $path = public_path('logo/' . $filename);
        Image::make($image->getRealPath())->resize(200, 200)->save($path);
        $file = $request->file('img');
        return ['url' => url('logo/' . $filename)];
    }
}

刀片：

    <div id="left" class="logo2">
    <img class="images" id="image" src="#" alt="Your Logo"/>
        <form id="upload_form" action="{{ action('BusinessController@image') }}" enctype="multipart/form-data" role="form" method="POST">
        <input type="hidden" name="_token" value="{{ csrf_token() }}">
        <input name="img" id="img" class="" data-input="false" type="file" data-buttonText="Upload Logo" data-size="sm" data-badge="false" onchange="submitImage();" />
</form>
    </div>
