【问题描述】:
我想在我的 HTTP Header 中发送 json 数据。
我正在使用 Codeigniter PHP,所以我在我的控制器中这样做了:
header('Content-Type: application/json');'
这是我的代码:
$request = array(
'request' => $_GET['request'],
'device_id' => $_GET['device_id'],
'launch_date'=> $_GET['launch_date'],
'allowed_hours'=>$_GET['allowed_hours'],
'site_id'=>$_GET['site_id'],
'product'=>$_GET['product'],
'software_version'=>$_GET['software_version'],
'platform_os'=>$_GET['platform_os'],
'platform'=>$_GET['platform'],
'platform_model'=>$_GET['platform_model']
);
$response = array(
'response_code' =>200 ,
'device_id'=>$_GET['device_id'],
'allowed_hours'=>$_GET['allowed_hours'],
'product'=>'mlc',
'prov_ur'=>NULL
);
header('Content-Type: application/json');
echo json_encode( $response );
但是当我打印我的标题时,我得到了

{"response_code":200,"device_id":"70D0D01FBAD2","allowed_hours":null,"product":"mlc","prov_ur":null}
在我的回复中。我不想在我的 HTTP 标头响应中发送其他数据。
根据 CI 更新代码
public function index()
{
$request = array(
'request' => $this->get('request'),
'device_id' => $this->get('device_id'),
'launch_date'=> $this->get('launch_date'),
'allowed_hours'=>$this->get('allowed_hours'),
'site_id'=> $this->get('site_id'),
'product'=>$this->get('product'),
'software_version'=> $this->get('software_version'),
'platform_os'=> $this->get('platform_os'),
'platform'=> $this->get('platform'),
'platform_model'=> $this->get('platform_model')
);
$response = array(
'response_code' =>200 ,
'device_id'=> $this->get('device_id'),
'allowed_hours'=> $this->get('allowed_hours'),
'product'=>'mlc',
'prov_ur'=>NULL
);
$this->output->set_content_type('Content-Type: application/json');
return $this->output
->set_content_type('Content-Type: application/json')
->set_output(json_encode($response));
echo $response;
}
【问题讨论】:
-
错误解释了问题 - 缺少 GET 变量 - 确保在发送响应之前设置它们
-
@RamRaider 我已经在数组 $request 中设置了我的 GET 变量
-
Message: Undefined index: allowed_hours这行提示需要先设置:'allowed_hours' -

谢谢@RamRaider 我明白了
