这是我的路线。我使用TaskController类的资源
Route::resource('main',TaskController::class);
这是我在main.blade.php中的帖子表单。我知道laravel帖子表单必须输入$crsf
<form action="" method="post" enctype="multipart/form-data"">
@csrf
@method('POST')
<input type="file" class="form-control"name="img" accept="image/*">
<button class="btn btn-primary" name="upload" type="submit" value="ok">Button</button>
</form>
这是我的任务控制器。我使用函数index((，并尝试删除进程，如果它在中显示空白页

当我提交我的表格时，laravel显示黑色页面。问题可能出在哪里？
form标记中的action属性为空。将其更改为相应的路线
您需要设置表单上的操作以匹配您的资源：
<form action="/main" method="post" enctype="multipart/form-data"">
之后，如果您向该端点发布，那么将调用的控制器函数就是store。文档
我找到了一个解决方案。我改变了以下路线：
Route::resource('/main',TaskController::class);
至
Route::get('/main',[TaskController::class,'index']);
Route::post('/main',[TaskController::class,'index']);
