Last encoded character (before the paddings if any) is a valid base 64 alphabet but not a possible value #1610

简要描述

public String authGet(@PathVariable Long appId,
@RequestParam(name = "msg_signature", required = false) String signature,
@RequestParam(name = "timestamp", required = false) String timestamp,
@RequestParam(name = "nonce", required = false) String nonce,
@RequestParam(name = "echostr", required = false) String echostr) {
//...
if (wxCpService.checkSignature(signature, timestamp, nonce, echostr)) {
// 这里调 decrypt(echostr) 发生异常，应该是依赖的版本有冲突
return new WxCpCryptUtil(wxCpService.getWxCpConfigStorage()).decrypt(echostr);
}
return "非法请求";
