尝试将文件URL发布到DB时为什么会出现500错误？

Question

我不知道为什么在尝试将文件URL发布到数据库时出现500错误。在我的日志中，这表示我的控制器不存在，但确实存在。我在做什么错，我该如何解决？

注意：我正在使用from PyQt5.QtCore import Qt, QDateTime from PyQt5.QtWidgets import * from PyQt5 import QtGui class ParentWindow(QDialog): def __init__(self): super(ParentWindow, self).__init__() self.cw = None self.button = QPushButton('Go to child') self.button.clicked.connect(self.child) layout = QHBoxLayout() layout.addWidget(self.button) self.setLayout(layout) self.show() def child(self): self.cw = ChildWindow(self) self.hide() def parent(self): self.cw.close() self.show() class ChildWindow(QDialog): def __init__(self, parent): super(ChildWindow, self).__init__(parent) self.button = QPushButton('Go to parent') self.button.clicked.connect(self.parent().parent) layout = QHBoxLayout() layout.addWidget(self.button) self.setLayout(layout) self.show() if __name__ == '__main__': import sys app = QApplication(sys.argv) window = ParentWindow() sys.exit(app.exec_()) 运行该项目。我尝试将其切换并使用valet open，但仍然收到相同的错误。

这是我的控制器：

php artisan serve

这是我的路线：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FileuploadController extends Controller {

    public function store(Request $request) {
        if($request->get('file')) {
            $image = $request->get('file');
            $name = time().'.' . explode('/', explode(':', substr($image, 0, strpos($image, ';')))[1])[1];
            \Image::make($request->get('file'))->save(public_path('images/').$name);
        }

        $fileupload = new Fileupload();
        $fileupload->filename=$name;
        $fileupload->save();

        return response()->json('Successfully added');
    }
}

这是我的发帖请求（react.js）

<?php

Route::get('/', function () {
    return view('welcome');
});

Route::post('/', 'FileuploadController@store');

这是日志中的错误：

import React, { Component } from 'react';
import axios from 'axios';

export default class FileUploadComponent extends Component

    constructor(props) {
        super(props);

            image: ''
        };
        this.onFormSubmit = this.onFormSubmit.bind(this)
        this.onChange = this.onChange.bind(this)
        this.fileUpload = this.fileUpload.bind(this)
    }

    onFormSubmit(e){
        e.preventDefault();
        this.fileUpload(this.state.image);

        let files = e.target.files || e.dataTransfer.files;

            })
        };
        reader.readAsDataURL(file);
    }

    fileUpload() {

                file: this.state.image
            });
        });
    }

    render() {
        return(
            <form onSubmit={this.onFormSubmit}>

                <button type="submit">Upload</button>

        )
    }
