Question

Android从我的laravel 5.7 API上传图像，但是 $ request-> input（'image'）始终为空。我也尝试使用邮递员及其工作正常。有人可以帮我吗？ XD

使用邮递员表单数据类型的成功结果

if($request->hasFile('image')) 
{
   $image = $request->file('image');
   $name = time().'.'.$image->getClientOriginalExtension();
   $destinationPath = public_path('uploads/messenger');
   $image->move($destinationPath, $name);                                  
   $path = url('')."/webservices/public/uploads/messenger/".$name;

    $result=[
      "image_url"  => $path,
    ];  

    $succes = "1";
    $successMessage = "Image uploaded";
    $errorMessage = "";

}
else
{
    $result = (object) array();
    $succes = "0";
    $successMessage = "";
    $errorMessage = "Image not found";
}

使用Storage Facades存储文件：

在storage/app/public/uploads/messenger内创建文件夹：具有777权限

运行命令：php artisan storage:link以符号链接公用文件夹可用的存储文件夹内容

在您的控制器中：

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator; 
use Illuminate\Support\Facades\Storage;
use Carbon\Carbon;


    public function upload_image(Request $request){ 
    try{
         // added validator for image field 

        $validator = Validator::make($request->all(), [ 
            'image'=>'required|mimes:jpeg,jpg,png,gif|max:5120'
        ]);

        if ($validator->fails()) {
            $response=array('status'=>'error','result'=>0,'errors'=>implode(',',$validator->errors()->all()));
            return response()->json($response, 200);
       }else{
           if($request->hasFile('image')){
             $uniqueid=uniqid();
             $original_name=$request->file('image')->getClientOriginalName();
             $size=$request->file('image')->getSize();
             $extension=$request->file('image')->getClientOriginalExtension();
             $filename=Carbon::now()->format('Ymd').'_'.$uniqueid.'.'.$extension;
             $imagepath=url('/storage/uploads/messenger/'.$filename);
             $path=$request->file('image')->storeAs('public/uploads/messenger/',$filename);   

          $response=array('status'=>'success','result'=>1,'image'=>$imagepath);
          return response()->json($response, 200);
          }else{
          $response=array('status'=>'error','result'=>0,'errors'=>'no image found');
          return response()->json($response, 200);              
          }
       }
     }catch(\Exception $e){
        $response=array('status'=>'error','result'=>0,'errors'=>'Internal Server Error');
        return response()->json($response, 500);
    } 
  }

在从客户端像Content-Type : multipart/form-data或android上上传图像时添加postman标头

android上传的图像对laravel空
