Rails 调用微信红包接口的时候提示 “CA 证书出错，请登录微信支付商户平台下载证书”
情况
在调用微信现金红包接口的时候，发送请求，老是提示“CA 证书出错，请登录微信支付商户平台下载证书”，查了好多资料，找不到解决办法。
谁能给点提示，或者资料看一下。
补充：证书已经下到了。
def post_xml(action, xml)
apiclient_cert = cert_pem_to_x509(self.api_client_cert)
apiclient_key = key_pem_to_rsa(self.api_client_key)
conn = Faraday.new(ssl: {client_cert: apiclient_cert, client_key: apiclient_key}, headers: {'Content-Type' => 'application/xml'}) do |faraday|
faraday.adapter Faraday.default_adapter
end
res = conn.post(pay_url(action), xml, {'Content-Type' => 'application/xml'})
res end
def cert_pem_to_x509(cert_pem) cert_x509 = OpenSSL::X509::Certificate.new cert_pem end
def key_pem_to_rsa(key_pem) key_rsa = OpenSSL::PKey::RSA.new key_pem end
