Question

我正在尝试向外部API（以下代码）发出POST请求。我设法使curl编码在我的本地主机上工作，但是当我转到登台服务器时，curl返回错误Peer reports incompatible or unsupported protocol version(35)。通过阅读本文，我需要添加一个错误缓冲区以获取更多的调试信息，但是文档令人困惑。

但是，当我直接在服务器终端中发出卷曲请求时，我收到一个连接成功。这使我非常困惑，因为服务器显然能够发出卷曲请求。

PHP Curl代码

$curl = curl_init();

  curl_setopt_array($curl, array(
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_POSTFIELDS => json_encode($body),
    CURLOPT_HTTPHEADER => $header,
  ));

  $response = curl_exec($curl);
  $err = curl_error($curl);
  echo "response: " . $response;
  echo "<br><br>error: " . $err;

  curl_close($curl);

Answer 1

为了解决此问题，我使用https://www.ssllabs.com/ssltest/进行了服务器SSL测试，向我展示了哪些协议已经打开并在服务器上可用。

从那之后，我跟随着对这个问题TLS 1.2 not working in cURL的回答，向我展示了使用哪个PHP CURLOPT_SSLVERSION号来访问开放协议。

因此，我必须将以下代码行添加到我的Curl数组

CURLOPT_SSLVERSION => CURL_SSLVERSION_TLSv1_2

PHP Curl错误35-对等方报告协议版本不兼容或不受支持
