PHP函数file_get_contents()使用 https 协议时报错：SSL operation failed

        经常用file_get_contents()函数调用远程API，这次在使用时，提示SSL什么鬼，一想，可能是函数使用时验证证书，之前写的时候是正常的，但是过了一久就错误了，干脆就关闭验证。

$stream_opts = [    "ssl" => [        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ]
]; 
$response = file_get_contents("https://xxx.xxx.xxx",false, stream_context_create($stream_opts));
$stream_opts = [    "ssl" => [        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ]
]; 
$response = file_get_contents("https://xxx.xxx.xxx",false, stream_context_create($stream_opts));
$stream_opts = [    "ssl" => [        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ]
]; 
$response = file_get_contents("https://xxx.xxx.xxx",false, stream_context_create($stream_opts));
