file_get_contents（）：SSL操作失败，代码为1-服务器解决

Question

我有一个具有2个域的在线服务器，均由letsencrypt进行SSL认证

在域A上，我创建了一个包含json内容的文件，可以使用此代码从我的PC读取

MyClass.java

当我将文件上传到domainB时，我得到了

$url = 'https://www.domainA.com/feed.php';

$response = file_get_contents($url, true);
$obj = json_decode($response, true);

print_r($obj);

编辑

此代码存在相同的问题

Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed in ... 
Warning: file_get_contents(): Failed to enable crypto in ... 
Warning: file_get_contents(https://www.domainA.com/feed.php): failed to open stream: operation failed in ...

响应为

$url = 'https://www.domainA.com/feed.php';

$arrContextOptions=array(
    "ssl"=>array(
        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ),
);  

$result = file_get_contents($url, false, stream_context_create($arrContextOptions));

还有此CURL代码

failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in ...

我有

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ch);
curl_close($ch);

print_r($result);

$obj = json_decode($result, true);

print_r($obj);
