如果把Authorization里面的body用json的JSON_UNESCAPED_UNICODE编码，就不会报这个错误，但是错误会变成{"code":"PARAM_ERROR","message":"平台证书序列号Wechatpay-Serial错误"}
商家转账返回 SIGN_ERRORArray ( [code] => SIGN_ERROR [detail] => Array ( [detail] => Array ( [issue] => sign not match ) [field] => signature [location] => authorization [sign_information] => Array ( [method] => POST [sign_message_length] => 897 [truncated_sign_message] => POST /v3/transfer/batches 1658824362 f2cec1829dcd04172074cd100623110a -------- [url] => /v3/transfer/batches ) ) [message] => 错误的签名，验签失败 ) 这是返回的结果 按文档一步一步走的，麻烦看下什么原因 我这也排查不出啥了
