安裝win64OpenSSL-1_1_0j後重新啟動；以管理員許可權啟動powershell;
執行以下命令
set OPENSSL_CONF=c:\xampp\apache\conf\openssl.cnf
openssl req -config c:\xampp\apache\conf\openssl.cnf -new -out c:\xampp\apache\conf\server.csr -keyout c:\xampp\apache\conf\server.pem
openssl rsa -in c:\xampp\apache\conf\server.pem -out c:\xampp\apache\conf\server.key
openssl x509 -req -signkey c:\xampp\apache\conf\server.key -days 1024 -in c:\xampp\apache\conf\server.csr -out c:\xampp\apache\conf\server.crt
本方法屬於自簽名，可以實現簡單的https加密，但是由於現在安全機制更多會檢查ca機構的權威性從而決定是否信任，因此還是很多場景下無法使用。
在httpd-ssl.conf檔案中
SSLCertificateFile "C:/xampp/apache/conf/server.crt"
SSLCertificateKeyFile "C:/xampp/apache/conf/server.key"
SSLCertificateChainFile "C:/xampp/apache/conf/chain.crt"
最後發現我們們還是最好申請一個免費的DV證書吧，否則很多app都會抱怨的。
https://cloud.tencent.com/product/ssl
https://myssl.com/
上面這兩個連線可以用於檢驗證書的有效性。特別是myssl.com比較專業，其使用ghost寫的blog資訊也比較專業
如果沒有合法的證書，則可能出現如下錯誤資訊(以微信小程式開發時為例):
VM136:1 https://xxx.cn 對應的伺服器證書無效。控制檯輸入 showRequestInfo() 可以獲取更詳細資訊。
