Laravel 4 Codeception Laravel sendAjaxGetRequest返回空字符串

你知道为什么这会返回一个空字符串吗

public function tryToTest3(AcceptanceTester $I)
    {
        $I->wantTo('To see a 200 status code and a json response');
        $I->haveHttpHeader('Content-Type', 'application/json');

        $I->sendAjaxGetRequest('/users',array());

        $I->seeResponseCodeIs('200');
        $I->seeResponseIsJson();// until here green bar
        dd($I->grabResponse()); // empty string
    }

Scenario:
* I have http header "Content-Type","application/json"
* I send ajax get request "/users",
  [Response] 200
  [Page] http://localhost/laravel/phpunit/public/users
  [Cookies] []
  [Headers] {"Date":["Thu, 31 Jul 2014 08:49:58 GMT"],"Server":["Apache/2.2.22 (Ubuntu)"],"X-Powered-By":["PHP/5.4.6-1ubuntu1.4"],"Vary":["Accept-Encoding"],"Content-Length":["120"],"Content-Type":["text/html"]}
* I see response code is "200"
* I see response is json 
* I grab response 
string(0) ""

NB

在我的app/bootstrap/start.php中

if ((gethostname() === 'homestead') && (isset($_SERVER['REMOTE_ADDR'])) && ($_SERVER['REMOTE_ADDR'] === '127.0.0.1'))
{
    dd('homestead');
    $env = $app->detectEnvironment(['codeception' => ['homestead']]);
}
else
{ 
    $env = $app->detectEnvironment(['local' => ['homestead']]);
}

宅地永远不会印刷

而这将打印实际响应并打印homestead

试试这个，而不是$I->grabResponse（）

我也有同样的问题，但我认为我对测试工具的理解有误

在我的例子中，我试图测试由接受AJAX POST请求的控制器提供的JSON响应

我试图测试一条successfull样式的flash消息是否在div中显示给用户，但是由于我无法测试Javascript，所以我在响应中寻找JSON。然后我谈到了null作为JSON给出的情况

我尝试了所有可能的标题和组合，然后我在PHPtest.club中得到了这样的回应，我认为它可能会像帮助我一样帮助你

这是关于

sendPOST

和

sendAjaxPostRequest

之间的区别，然后我意识到我使用sendAjaxPostRequest的方式是错误的

基本上：

• sendajaxrequest

  用于测试

  HTML响应

  ，因此您应该使用

  请参见

  ，

  请参见元素

  以及这些方法

• sendX

  设计用于

  JSON响应

  而不是HTML，因此您应该使用

  seereponeissjson

  或所有其他方法

我希望能对你或其他人有所帮助

你好

我要感谢davert给我如此有意义的回复。

感谢你给我写了这么一封非常有用且提及不多的便条。
