详情：message: "cURL error 58: could not load PEM client certificate, OpenSSL error error:140AB18E:SSL routines:SSL_CTX_use_certificate:ca md too weak, (no key found, wrong pass phrase, or wrong file format?) (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)"

这样的报错应该是读取到了证书，然后解析不了。应该是openssl的原因，官方文档为啥没有说明。
