Raj*_*jan 5 php codeigniter http-headers phpwebsocket
我想在我的 HTTP 标头中发送 json 数据。
我使用的是 Codeigniter PHP,所以我在我的控制器中做了这个:
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 );

在我的回应中。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;
}

使用像下面这样的普通 php get 有时会抛出一些错误
\n\n$_GET[\'allowed_hours\'];\nRun Code Online (Sandbox Code Playgroud)\n\n我建议更改 codeIgniter 输入类方法。
\n\n$this->input->get(\'allowed_hours\');\nRun Code Online (Sandbox Code Playgroud)\n\nCodeigniter输入类将为您节省大量代码。
\n\n正如用户指南中所述:使用 CodeIgniter\xe2\x80\x99s 内置方法,您可以简单地执行以下操作:
\n\n更新:
\n\n$request = array(\n \'request\' => $this->input->get(\'request\'),\n \'device_id\' => $this->input->get(\'device_id\'),\n \'launch_date\'=> $this->input->get(\'launch_date\'),\n \'allowed_hours\'=> $this->input->get(\'allowed_hours\'),\n \'site_id\'=> $this->input->get(\'site_id\'),\n \'product\'=>$this->input->get(\'product\'),\n \'software_version\'=> $this->input->get(\'software_version\'),\n \'platform_os\'=> $this->input->get(\'platform_os\'),\n \'platform\'=> $this->input->get(\'platform\'),\n \'platform_model\'=> $this->input->get(\'platform_model\')\n);\nRun Code Online (Sandbox Code Playgroud)\n\nCodeigniter 有自己的输出类
\n\n和
\n\n$response = array(\n \'response_code\' => 200,\n \'device_id\'=> $this->input->get(\'device_id\'),\n \'allowed_hours\'=> $this->input->get(\'allowed_hours\'),\n \'product\'=> \'mlc\',\n \'prov_ur\'=> NULL \n);\n\nreturn $this->output\n ->set_content_type(\'Content-Type: application/json\')\n ->set_output(json_encode($response));\nRun Code Online (Sandbox Code Playgroud)\n
