Question

尝试运行任何测试时，我收到以下错误：

json_encode（）：type不受支持，编码为null

我正在使用v 2.0.1

测试代码：

$I = new ApiTester($scenario);
$I->wantTo('get a list of all users');
$I->haveHttpHeader('Content-Type','application/x-www-form-urlencoded');
$I->sendGET('users'); // <-- error happens here
$I->seeResponseCodeIs(200);
$I->seeResponseIsJson();
$I->seeResponseContains('{ result: ok}');

以下示例输出：

    I have http header "Content-Type","application/x-www-form-urlencoded"

    I send get "users"
    [Request] GET http://api.myapp.com/users

我还得到了Laravel默认欢迎页面的简单验收测试错误：

$I = new AcceptanceTester($scenario);
$I->wantTo('see the Laravel welcome page');
$I->amOnPage('/');
$I->shouldSee('You have arrived.');

原来这个问题是时区没有在php.ini中设置。我将相关的行添加到/etc/php.ini中，现在可以使用了。

示例/etc/php.ini:(PHP 5.4.19）

date.timezone = "Europe/London"
error_reporting  =  E_ALL
display_errors = On
html_errors = On

zend_extension=/usr/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so

extension=mcrypt.so
