在对接小程序连续包月功能遇到报错：暂时无法开通此服务，商家系统错误，请联系商家处理 小程序页面报错截图这样的： [图片] 后端返回的数据是这样的： [图片] 前端代码是这样的： [图片] 报错信息不够相信我们不好排查具体问题，签名校验也都能通过，希望有遇到相似问题的大佬们能够指正错误

报错：Processing WechatPay notification,signature verification failed,signType[WECHATPAY2-SHA256-RSA2048]  原因：HTTP 请求体 body。切记使用原始报文，不要用 JSON 对象序列化后的字符串，避免验签的 body 和原文不一致。（body顺序乱了不行，HttpServletRequest只能被读取一次） 处理HttpServletRequest工具类： import com.wechat.pay.java.core.notification.RequestParam; import javax.servlet.ServletInputStream; import javax.servlet.http.HttpServletRequest; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.nio.charset.StandardCharsets; public class HttpServletRequestUtils { public static String getRequestBody(HttpServletRequest request) { StringBuilder sb = new StringBuilder(); try (ServletInputStream inputStream = request.getInputStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, StandardCharsets.UTF_8)); ) { String line; while ((line = reader.readLine()) != null) { sb.append(line); } } catch (IOException e) { System.out.println(e.getMessage()); } return sb.toString(); } public static RequestParam createRequestParam(HttpServletRequest request){ String body = getRequestBody(request); 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 number = request.getHeader("Wechatpay-Serial"); return new RequestParam.Builder() .nonce(nonce) .signature(signature) .signType(singType) .timestamp(timestamp) .serialNumber(number) .body(body) .build(); } }
