获取body片段，使用的issue里另一位提供的，试过网上多种getbody的代码

private String getRequestBody(HttpServletRequest request) {
        BufferedReader br = null;
        try {
            StringBuilder result = new StringBuilder();
            br = request.getReader();
            for (String line; (line = br.readLine()) != null; ) {
                if (result.length() > 0) {
                    result.append("\n");
                }
                result.append(line);
            }
            return result.toString();
        } catch (IOException e) {
            throw new RuntimeException(e);
        } finally {
            if (br != null) {
                try {
                    br.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        } 

这是另一个

private String getRequestBody(HttpServletRequest request) {
        String body;
        try (ServletInputStream inputStream = request.getInputStream()
        ) {
            ByteArrayOutputStream result = new ByteArrayOutputStream();
            byte[] buffer = new byte[1024];
            for (int length; (length = inputStream.read(buffer)) != -1; ) {
                result.write(buffer, 0, length);
            }
            body = result.toString();
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        return body;
    } 

两种都是一致的报错。

这是获取微信端回调的方式。

// 从请求头中获取信息
        String timestamp                        = request.getHeader("Wechatpay-Timestamp");
        String nonce                            = request.getHeader("Wechatpay-Nonce");
        String signature                        = request.getHeader("Wechatpay-Signature");
        String singType                         = request.getHeader("Wechatpay-Signature-Type");
        String wechatPayCertificateSerialNumber = request.getHeader("Wechatpay-Serial");

        String requestBody = getRequestBody(request);

        // 构造 RequestParam
        RequestParam requestParam = new RequestParam.Builder()
                .serialNumber(wechatPayCertificateSerialNumber)
                .nonce(nonce)
                .signature(signature)
                .signType(singType)
                .timestamp(timestamp)
                .body(requestBody)
                .build();

由于微信小程序时2025年之后开的，使用sdk为0.2.16，所以都是使用RSAPublicKey 获取的config
