php - 错误 :error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

Question

$ch = curl_init();
$clientId = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/oauth2/token");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, $clientId.":".$secret);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close ($ch);

这段代码在本地主机上工作，但是当我在我的实时服务器上测试时，它会给我这个错误 Error:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure 然后我尝试了这个

<?php
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, "https://tlstest.paypal.com/"); 
curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
var_dump(curl_exec($ch));
if ($err = curl_error($ch)) {
var_dump($err);
echo "DEBUG INFORMATION:\n###########";
echo "CURL VERSION";
echo json_encode(curl_version(), JSON_PRETTY_PRINT);
}?>

github.com/paypal/TLS-update/tree/master/php 这将再次在 localhost 和 live 上运行它给了我这个

error bool(false)
string(67) "Unknown SSL protocol error in connection to tlstest.paypal.com:443 "
DEBUG INFORMATION:

Answer 1

TL;TR:您的软件太旧，无法支持这些服务器。

这两个服务器都只支持 TLS 1.2，这在检查 SSLLabs 时可以看出。 .您的 OpenSSL 版本是 1.0.0s，尚不支持 TLS 1.2。仅从 1.0.1 开始提供支持。

my server have these certificates ...

您的 Web 服务器的设置(即证书、TLS 版本...)无关紧要，因为在这种情况下您是连接到其他服务器的客户端。
