Laravel $ request-> expectsJson() [英] Laravel $request->expectsJson()

问题描述

我正在为Laravel应用程序进行Ajax登录.

I am doing an Ajax login for my Laravel application.

我正在使用Angular:

I am using Angular:

$http({
  method: 'POST',
  url: '/admin/login',
  headers: {
        'Content-Type': 'application/json'
  },
  data: {email:$scope.email,password:$scope.password}
})

此请求工作正常，我的问题是Laravel的响应总是重定向我，因为如果我不发送JSON，它应该

This request works fine, my problem is that Laravel's response always redirects me, as it should if I wasn't sending JSON:

protected function sendFailedLoginResponse(Request $request)
    {
        $errors = [$this->username() => trans('auth.failed')];
        if ($request->expectsJson()) {
            return response()->json($errors, 422);
        }
        return redirect()->back()
            ->withInput($request->only($this->username(), 'remember'))
            ->withErrors($errors);
    }

这是Laravel框架代码.它使我一直重定向，但我想触发条件if ($request->expectsJson())并获取JSON响应而不是重定向.

That is the Laravel framework code. It keeps redirected me back, but I want to fire the conditional if ($request->expectsJson()) and get a JSON response rather than a redirect.

要触发该条件，我缺少什么?

What am I missing in order to trigger that conditional?

我什至添加了

 headers: {
        'Content-Type': 'application/json','X-Requested-With' :'XMLHttpRequest'
  }

它仍然无法正常工作.

expectsJson() :

public function expectsJson()
    {
        return ($this->ajax() && ! $this->pjax()) || $this->wantsJson();
    }

我的标题:

接受:application/json，文本/纯文本，/

Accept-Encoding:gzip，放气

Accept-Language:en-US，en; q = 0.8

Content-Type:application/json

Content-Type:application/json

出于安全原因，我不包含令牌/cookie和原始URL，但是它们在其中.

I'm not included tokens/cookies and the origin url for security reason, but they are in there.

我试图清除手工艺品的缓存，但还是一无所获.

I tried clearing the artisan cache and still nothing.

php artisan cache:clear

也

composer dump-autoload

推荐答案

您应该使用Accept键而不是Content/type.有关更多详细信息，请检查此github讨论
