【Help】使用demo中的例子上传图片返回400 badrequest

[zzmloveddm]

可否帮忙看下这个是啥情况 代码如下： PrivateKey merchantPrivateKey = PemUtil.loadPrivateKey(Files.newInputStream(Paths.get(PrivateKeyPath))); //使用自动更新的签名验证器，不需要传入证书 verifier = new AutoUpdateCertificatesVerifier( new WechatPay2Credentials(tMerchantId, new PrivateKeySigner(MerchantSerialNumber, merchantPrivateKey)), ApiV3key.getBytes(StandardCharsets.UTF_8)); httpClient = WechatPayHttpClientBuilder.create() .withMerchant(MerchantId, MerchantSerialNumber, merchantPrivateKey) .withValidator(new WechatPay2Validator(verifier)) .build(); URI uri = new URI("https://api.mch.weixin.qq.com/v3/merchant/media/upload"); byte[] bytes = file.getBytes(); try (InputStream byteArrayInputStream = new ByteArrayInputStream(bytes)) { String sha256 = DigestUtils.sha256Hex(byteArrayInputStream); WechatPayUploadHttpPost request = new WechatPayUploadHttpPost.Builder(uri) .withImage(file.getOriginalFilename(), sha256, byteArrayInputStream) .build(); Header[] allHeaders = request.getAllHeaders(); for (Header allHeader : allHeaders) { System.out.println(allHeader); } try (CloseableHttpResponse response = httpClient.execute(request)) { if (SC_OK == response.getStatusLine().getStatusCode()){ HttpEntity entity = response.getEntity(); // do something useful with the response body // and ensure it is fully consumed String s = EntityUtils.toString(entity); System.out.println(s); return success; }else { return error; } } } 返回400 badrequest

400只是状态码。你需要把应答流收回来，输出 body，看到错误码和错误信息。它们可以用来定位问题。
