我们方面没有任何变化，也许与POODLE / SSL3有关，我们对PPIPNMessage :: validate的PayPal API调用现在失败了。
SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
IPN的结账和接收很好（我们从未支持SSL3传入），只是在确认IPN时失败（奇怪的是PayPal不会再次尝试，即使我们失败了）

我注意到ssllabs.com显示4个IP中有1个仍支持此端点上的SSL3。
答案 0 :(得分：32)
这与Error 0x1408F10B: "SSL3_GET_RECORD:wrong version number" with PayPal SDK
的问题相同我们使用硬编码CURLOPT_SSLVERSION到3的PayPal API版本。
我们的解决方法是在任何PayPal调用之前插入此内容。
PPHttpConfig::$DEFAULT_CURL_OPTS[CURLOPT_SSLVERSION] = 4;
答案 1 :(得分：15)
我遇到了同样的问题......只需更改 ipnlistener.php
上的以下行从：
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
为：
curl_setopt($ch, CURLOPT_SSLVERSION, 4);

答案 2 :(得分：13)
PayPal禁用SSLv3以响应“POODLE”的可用性。在此处阅读：PayPal Response
如果您使用的是ipnlistener.php，请强制使用TLS 1.2作为SSL协议：
curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
（更新：2017年需要TLS V1.2）
注意： PayPal正在升级用于保护对其系统进行的所有外部连接的协议。传输层安全版本1.2（TLS 1.2）和超文本传输协议版本1.1（HTTP / 1.1）将成为2018年与PayPal通信的强制性要求。请参阅他们的Security Roadmap
答案 3 :(得分：2)
www.paypal.com不再提供SSLv3：
# sslscan www.paypal.com|grep Accepted
Accepted TLSv1 256 bits AES256-SHA
Accepted TLSv1 128 bits AES128-SHA
Accepted TLSv1 168 bits DES-CBC3-SHA
Accepted TLSv1 128 bits RC4-SHA
Accepted TLSv1 128 bits RC4-MD5
您应该将 CURLOPT_SSLVERSION 更改为 TLSv1 ：
curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
（此“CURL_SSLVERSION_TLSv1” - 常量不适用于较旧的PHP版本，因此另一种方法是仅删除CURLOPT_SSLVERSION强制执行。）
答案 4 :(得分：1)
对我来说，其他答案中提到的这些事情都没有起作用，但是，我能够找出解决方案并且它是一致的，但是花了一些时间来找出我正在使用的sdk的文件放了它的卷曲配置，因为没有ipn监听器文件，“PPHttpConfig”会给我一个致命的错误
所以我发现这是他们现在使用的监听器文件：
贝宝PHP-SDK /贝宝/ REST的API-SDK-PHP / LIB /贝/核心/ PayPalHttpConfig.php
我在里面找到了
CURLOPT_SSLVERSION =＆gt; 1
我把它改为：
CURLOPT_SSLVERSION =＆gt; 4
并为我修好了。
答案 5 :(得分：0)
我是第二个。 失去了小时试图找出它。 在我的IPN监听器上，我不得不删除'force ssl v3'。 从那时起，我的IPN再次开始工作。
做一个 curl -v https://paypal.com
它显示： 使用TLS_RSA_WITH_AES_256_CBC_SHA
进行SSL连接答案 6 :(得分：0)
我在使用PayPal检查IPN时遇到同样的错误。这是问题的解决方案
我使用PHP 5.3并且PHP 5.3不再支持SSL版本3.我已经使用5.4升级了PHP版本并添加了以下代码行。这对我有用。
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
#curl_setopt($ch, CURLOPT_SSLVERSION, 4);
curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
curl_setopt($ch, CURLOPT_SSL_CIPHER_LIST, 'TLSv1');
答案 7 :(得分：-2)
在paypal类中使用此设置调用函数PPHttpPost（）
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSLVERSION, 6); //6 is for TLSV1.2
