微信支付,使用证书时出现58错误

　　近期正在开发微信支付功能，用crul调用证书时提示类似错误

　　58 problem with the local client certificate.

　　经过查找手册和实验，参考php手册提供的以下方案可以解决，代码如下

If you want to connect to a server which requires that you identify yourself with a certificate, use following code. Your certificate and servers certificate are signed by an authority whose certificate is in ca.ctr. 

<?php
curl_setopt($ch, CURLOPT_VERBOSE, ‘1‘); 　　　　//启用时会汇报所有的信息，存放在STDERR或指定的 CURLOPT_STDERR 中。
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, ‘2‘); 　　//2 检查公用名是否存在，并且是否与提供的主机名匹配。
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, ‘1‘); 　　//cURL从服务端进行验证
curl_setopt($ch, CURLOPT_CAINFO,  getcwd().‘/cert/ca.crt‘);
curl_setopt($ch, CURLOPT_SSLCERT, getcwd().‘/cert/mycert.pem‘);
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, ‘password‘);
?> 

If your original certificate is in .pfx format, you have to convert it to .pem using following commands
# openssl pkcs12 -in mycert.pfx -out mycert.key
# openssl rsa -in mycert.key -out mycert.pem
# openssl x509 -in mycert.key >> mycert.pem
