Laravel：如何上传图像并通过API邮递员保存到数据库（phpmyadmin）

Question

我想知道如何上传一个图像通过API邮递员在拉威尔和保存到我的数据库，这是phpMyAdmin。当我尝试在postman中运行代码时，会显示以下内容：

"image null" 

这是我目前的代码：

横幅积垢控制器：

    <?php

namespace App\Http\Controllers\Api;

use App\Http\Controllers\Controller;
use App\Models\Banner;
use Illuminate\Http\Request;

class BannerCRUDController extends Controller
{
    /**
    * Display a listing of the resource.
    *
    * @return \Illuminate\Http\Response
    */
    public function index()
    {
        $banners = Banner::all();
        return response($banners,200);
    }
 
    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }
 
    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $data = $request->validate([
            'id'=>'required',
            'web_banner_profile'=>'required',
        ]);
 
        $image = $request->file('image');
        if($request->hasFile('image')) {
            $new_name = rand() . '.' . $image->getClientOriginalExtension();
            return response()->json($new_name); 
        }else{
            return response()->json('image null');
        }

        $banners = Banner::create($data);

        return response ($banners, 200);
    }
 
    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }
 
    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }
 
    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
       //
    }
 
    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
       //
    }
 }
 

横幅型号：

    <?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Banner extends Model
{
    public $table = "webinar";
    use HasFactory;

    protected $fillable = [
        'id',
        'web_banner_profile',
    ];
}

任何关于我做错了什么的想法，我想现在就得到这个，因为我有很多表格需要创建。

希望有人能帮助我开始。谢谢。

错误是清除请求具有空图像。所以你应该选择关键类型文件在邮递员

Answer 2

在BannerCrudeController中将存储功能替换为以下内容。php
在存储器中创建图像目录。

public function store(Request $request)
    {
        $data = $request->validate([
            'id'=>'required',
            'web_banner_profile'=>'required',
        ]);
 
        $image = $request->file('image');
        if($request->hasFile('image')) {
             $image = $request->file('image');
             $destinationPath = storage_path('images');
             $fileName = str_random(6) . time() . "." . $image->getClientOriginalExtension();
             $image->move($destinationPath, $fileName);
             $banner = new Banner();
             $banner->web_banner_profile = $fileName:
             $banner->save()
            return response()->json($fileName); 
        }else{
            return response()->json('image null');
        }

      
    }

图像将上传到存储/图像中。

您只需使用此代码上传图像，并在邮递员选择类型文件

public function store(Request $request)
    {
        $data = $request->validate([
            'id'=>'required',
            'web_banner_profile'=>'required',
        ]);
 
        $image = $request->file('image');
        if($request->hasFile('image')) {
            $image = time() . '.' . $request->image- 
           >getClientOriginalExtension();
           $request->image->move(public_path('Your Path'), $image);
           $banner->image = 'Your Path' . $image;
   
            return response()->json($image); 
        }else{
            return response()->json('image null');
        }

        $banners = Banner::create($data);

        return response ($banners, 200);
    }
