1.提示这个错误

如果用户使用的是本地开发环境，比如Windows，可能需要下载最新的CA证书，并在php.ini中配置curl.cainfo路径。

{
    "sta": 1,
    "msg": "失败！cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://dm.aliyuncs.com/?AccountName=service%40send.dlxswh.com&AddressType=1&HtmlBody=%E4%BD%A0%E6%9C%AC%E6%AC%A1%E7%9A%84%E9%AA%8C%E8%AF%81%E7%A0%81%E4%B8%BA%3A5029%EF%BC%8C%E8%AF%B7%E5%A6%A5%E5%96%84%E4%BF%9D%E7%AE%A1%EF%BC%8C%E4%B8%8D%E8%A6%81%E5%91%8A%E8%AF%89%E5%85%B6%E4%BB%96%E4%BA%BA%E3%80%82&ReplyToAddress=true&Subject=%E9%80%9A%E7%9F%A5&ToAddress=613154514%40qq.com"
}

2.下载 

https://curl.se/docs/caextract.html

3.在php.ini增加如下

curl.cainfo="D:/phpstudy_pro/Extensions/php/php7.4.3nts/ext/cacert.pem"
openssl.cafile="D:/phpstudy_pro/Extensions/php/php7.4.3nts/ext/cacert.pem"
