php - 为什么这个 curl 函数获得权限被拒绝

问题描述

我正在尝试与 Kodi JSONRPC api 通信，但我一直被拒绝许可。

我到处寻找，我尝试了所有我能找到的 curl 选项，但它们似乎都没有做任何事情。

$options = array(
        CURLOPT_VERBOSE => 1,
        CURLOPT_RETURNTRANSFER      => true,
        CURLOPT_HEADER              => true,
        CURLOPT_HTTPHEADER          => array(                                                                          
        'Content-Type: application/json',                                                                                
        'Content-Length: ' . strlen($data_string)),
        CURLOPT_ENCODING            => "",       
        CURLOPT_USERAGENT           => "curl/7.65.1", 
        CURLOPT_POSTFIELDS          => $data_string,
    );

$ch = curl_init( $url );
curl_setopt_array( $ch, $options );
$info = curl_getinfo($ch);
$content = curl_exec( $ch );

print_r($info);
echo $content;

我得到了一些令人不安的回应，我的 curl 请求如下所示：

Array
(
    [url] => http://10.1.1.214:8080/jsonrpc
    [content_type] => 
    [http_code] => 0
    [header_size] => 0
    [request_size] => 0
    [filetime] => 0
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 0
    [namelookup_time] => 0
    [connect_time] => 0
    [pretransfer_time] => 0
    [size_upload] => 0
    [size_download] => 0
    [speed_download] => 0
    [speed_upload] => 0
    [download_content_length] => -1
    [upload_content_length] => -1
    [starttransfer_time] => 0
    [redirect_time] => 0
    [certinfo] => Array
        (
        )

    [primary_ip] => 
    [primary_port] => 0
    [local_ip] => 
    [local_port] => 0
    [redirect_url] => 
)

我的 error_log 看起来像这样：

* About to connect() to 10.1.1.214 port 8080 (#69)
*   Trying 10.1.1.214...
* Failed to connect to 10.1.1.214: Permission denied
* couldn't connect to host at 10.1.1.214:8080
* Closing connection 69

命令行中的成功命令如下所示：

curl -v --data-binary '{"jsonrpc": "2.0", "method": "Application.GetProperties", "params": {"properties": ["version"]}, "id": 1}' -H 'content-type: application/json'  http://10.1.1.214:8080/jsonrpc

解决方案

事实证明，问题在于 SELINUX 策略。

通过运行以下命令，它将解决问题

#setsebool -P httpd_can_network_connect=1
