我使用Laravel护照进行身份验证
在路线api.php中
Route::get('/todos', function(){
return 'hello';
})->middleware('auth:api');
但是当打开localhost：8000 / api / todos时，我看到以下错误
InvalidArgumentException
Route [login] not defined.
* @return string
*
* @throws \InvalidArgumentException
*/
public function route($name, $parameters = [], $absolute = true)
{
if (! is_null($route = $this->routes->getByName($name))) {
return $this->toRoute($route, $parameters, $absolute);
}
throw new InvalidArgumentException("Route [{$name}] not defined.");
}
/**
* Get the URL for a given route instance.
*
* @param \Illuminate\Routing\Route $route
* @param mixed $parameters
* @param bool $absolute
* @return string
* …嗨在Laravel安装中发生以下错误
user@user-System-Product-Name:/$ composer global require "laravel/installer"
Changed current directory to /home/user/.config/composer
Using version ^2.0 for laravel/installer
./composer.json has been created
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- laravel/installer v2.0.1 requires ext-zip * -> the requested PHP extension zip is missing from your system.
- laravel/installer v2.0.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
- Installation …我正在使用android studio 3.2，并且想在我的空白类中使用SQLiteOpenHelper。当我运行项目Java编译器时返回错误：找不到符号类可为空
public class Db extends SQLiteOpenHelper {
public Db(@androidx.annotation.Nullable Context context, @androidx.annotation.Nullable String name, @androidx.annotation.Nullable SQLiteDatabase.CursorFactory factory, int version) {
super(context, name, factory, version);
}}
我也用了这个实现
implementation 'com.android.support:support-annotations:24.2.0'
我单击了“使缓存无效”，然后在文件菜单上重新启动并重建项目，但仍然发生错误
先感谢您
