我记得post要返回一个“success”

服务端代码:

@GetMapping("/wechat/receive")
public ResponseEntity check(@RequestParam String signature,
                            @RequestParam String echostr,
                            @RequestParam String timestamp,
                            @RequestParam String nonce) throws AesException {
    log.info("GET 收到通知, signature:{} echostr:{},timestamp:{},nonce:{} ", signature, echostr, timestamp, nonce);
    List<String> list = new ArrayList<>();
    list.add(echostr);
    list.add(timestamp);
    list.add(nonce);
    wxUserService.checkReceive(signature, echostr, timestamp, nonce, "");
    return ResponseEntity.ok(echostr);
}
@PostMapping("/wechat/receive")
public ResponseEntity<String> receiveEvent(@RequestBody WxEncryptEvent wxEncryptEvent, @RequestParam String signature,
                               @RequestParam String echostr,
                               @RequestParam String timestamp,
                               @RequestParam String nonce,
                               @RequestParam String openid,
                               @RequestParam String encrypt_type,
                               @RequestParam String msg_signature) {
    log.info("收到通知body:{} echostr:{} timestamp:{} nonce:{} openid:{} encrypt_type:{} msg_signature:{}",
            wxEncryptEvent, echostr, timestamp, nonce, openid, encrypt_type, msg_signature);
    try {
        wxUserService.receiveEvent(wxEncryptEvent, echostr, timestamp, nonce, openid, encrypt_type, msg_signature);
        return ResponseEntity.ok("");
    }catch (Exception e){
        log.error("", e);
    }
    return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("");

}
