curl "Unknown SSL protocol error in connection" error in server, but works on local
提问by martriay
I'm trying to retrieve data from a site (i've censored the url) with this code:
我正在尝试使用以下代码从站点检索数据（我已经了网址）：
<?php
$url = [doesnt really matter];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$archivo_xml = fopen("test.tst", "w");
curl_setopt($ch, CURLOPT_FILE,$archivo_xml);
curl_exec($ch);
$as1 = curl_getinfo($ch, CURLINFO_NAMELOOKUP_TIME);
$as2 = curl_getinfo($ch, CURLINFO_CONNECT_TIME);
$as3 = curl_getinfo($ch, CURLINFO_PRETRANSFER_TIME);
$as4 = curl_getinfo($ch, CURLINFO_STARTTRANSFER_TIME);
$as5 = curl_getinfo($ch, CURLINFO_TOTAL_TIME);
echo "Lookup: ",$as1," \n\r Connect: ",$as2," \n\r Pretransfer: ",$as3," \n\r Starttransfer: ",$as4," \n\r Total: ",$as5,"\n\r","Error: ", curl_error($ch), "\n\r";
curl_close($ch);
fclose($archivo_xml);
?>
It work's fine on local but not in the server. Here's the output from local:
它在本地运行良好，但在服务器中运行不正常。这是本地的输出：
Lookup: 0.015155
Connect: 0.0281
Pretransfer: 0.129087
Starttransfer: 0.786341
Total: 0.786384
Error:
and here's the output from the server:
这是服务器的输出：
Lookup: 0.028731
Connect: 0.043182
Pretransfer: 0
Starttransfer: 0
Total: 60.057787
Error: Unknown SSL protocol error in connection to [censored url]
With any other url works just fine, the problem is with this specific one.
任何其他网址都可以正常工作，问题出在这个特定的网址上。
localhost PHP version: 5.4.23
本地主机 PHP 版本：5.4.23
server PHP version: 5.5.7
服务器 PHP 版本：5.5.7
Thanks in advance
提前致谢

SOLVED. Because of this known bug http://sourceforge.net/p/curl/bugs/1319/I downgraded curl to 7.33 and it worked.
解决了。由于这个已知的错误http://sourceforge.net/p/curl/bugs/1319/我将 curl 降级到 7.33 并且它起作用了。

Try setting cURLparam
尝试设置cURL参数
curl_setopt($ch, CURLOPT_SSLVERSION,3); // Apparently 2 or 3
回答by Chintan
As in the case of this post adding curl_setopt($ch, CURLOPT_SSLVERSION,3);did not immediately resolve the issue today the SSL has been re-validated and accepted.
就像这篇文章的情况一样，今天添加curl_setopt($ch, CURLOPT_SSLVERSION,3);并没有立即解决问题，SSL 已被重新验证并被接受。

I had a similar situation with the same error. Using a constant like this made it work:
我有同样的错误的类似情况。使用这样的常量使其工作：
curl_setopt( $handle, CURLOPT_SSLVERSION, 'CURL_SSLVERSION_SSLv3' );

Other constants: https://curl.haxx.se/libcurl/c/CURLOPT_SSLVERSION.html
其他常量：https: //curl.haxx.se/libcurl/c/CURLOPT_SSLVERSION.html

Try with both options
尝试两个选项
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
If still not working then URL might be blocked on your server.
如果仍然无法正常工作，则 URL 可能在您的服务器上被阻止。
