Question

我正在尝试通过dropzone上传图片，但是我得到了tokenmismatch错误，即使我在所需的地方添加了csrf令牌，我也非常绝望......

我的表单

{!! Form::open(['route' => 'photo.upload', 'id' => 'hello', 'method' => 'POST', 'class' => 'dropzone no-margin dz-clickable']) !!}
    <div class="dz-default dz-message"><span>Drop files here to upload</span></div></form>
{!! Form::close() !!}

我的剧本

Dropzone.autoDiscover = false;

Dropzone.options.hello = {
    paramName: "file", // The name that will be used to transfer the file
    maxFilesize: 5, // MB
    parallelUploads: 2, //limits number of files processed to reduce stress on server
    addRemoveLinks: true,
    headers: {
        'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content'),
    },
    accept: function(file, done) {
        // TODO: Image upload validation
        done();
    },
    sending: function(file, xhr, formData) {

        // Pass token. You can use the same method to pass any other values as well such as a id to associate the image with for example.
        formData.append("_token", $('input[name="_token"]').val() ); // Laravel expect the token post value to be named _token by default
    },
    init: function() {
        this.on("success", function(file, response) {
            // On successful upload do whatever :-)
        });
    }
};

// Manually init dropzone on our element.
var myDropzone = new Dropzone("#hello", {
    url: $('#hello').attr('action')
});

当我查看生成的表格时，有csrf字段

<input name="_token" type="hidden" value="P4wc9NVVZJe1VjalPwO6d6WQXZ9eEqPd84ICpToG">

你知道为什么即使把crsf令牌放在我应该的地方它也不起作用吗？

谢谢你的时间。

Answer 1

只需在表单中放置隐藏字段，如

<input type="hidden" name="_token" value="{{csrf_token()}}">

您可以通过使用ajax调用（如

）传递令牌的值来使其不同

$(function () {
    $.ajaxSetup({
        headers: { 'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content') }
    });
});

Answer 2

而不是创建有点脏的新元素。您可以将其包含在手动初始化dropzone中。

var myDropzone = new Dropzone("#hello", { 
            url: $('#hello').attr('action'),
            headers: {
               'x-csrf-token': document.querySelectorAll('meta[name=csrf-token]')[0].getAttributeNode('content').value,
            }
          });
