CURL_SSLVERSION_TLSv1
近一段时间HTTPS加密协议SSL曝出高危漏洞,可能导致网络中传输的数据被黑客监听,对用户信息、网络账号密码等安全构成威胁。为保证用户信息以及通信安全,微信公众平台将关闭掉SSLv2、SSLv3版本支持,不再支持部分使用SSLv2、 SSLv3或更低版本的客户端调用。请仍在使用这些版本的开发者于11月30日前尽快修复升级。
注意:通过微信开放平台(open.weixin.qq.com)进行移动应用和网页应用开发的开发者也同样 需要修复升级。
建议开发者使用如下方法进行修复:
OpenSSL(http://www.openssl.org)可使用SSL_CTX *SSL_CTX_new(const SSL_METHOD *method)函数设置SSL客户端请求方法,使用TLSv1_client_method或更高版本。
示例1(php):curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
为什么 我写了就会报错?
A PHP Error was encountered
Severity: Notice
Message: Use of undefined constant CURL_SSLVERSION_TLSv1 - assumed 'CURL_SSLVERSION_TLSv1'

用数字 1 代替就可以了
<code>php > var_dump(CURL_SSLVERSION_TLSv1); int(1) </code>
可能你的 php 版本低了
