当前已知这个客诉图片下载的图片URL上，可能含percent-encoded字符串，这个如果稍微不注意就会报400错误(签名失败)，如果你使用的是PHPsdk，建议参考这里的测试用例，进行校准实现。 https://github.com/wechatpay-apiv3/wechatpay-php/blob/main/tests/OpenAPI/V3/MerchantService/Images/DownloadTest.php#L168-L214
消费者投诉—图片下载API 接口返回状态码400消费者投诉—图片下载接口，有的media_url接口调用失败，返回400； 1. 部分图片显示不了，不是全部。调用"下载图片"接口，返回只返回状态码为400； 2. 图片是通过调用"提交回复"接口上传的（经过了"商户上传反馈图片"接口）； 3. 存在同时上传两张图片，一张正常下载，另一张下载失败的情况； 4. 对应的有效期为1个小时的图片链接能够正常显示； 5. c端用户问题图片可以正常显示； 6. 商户后台问题图片也显示不了； 7. 上传的图片大小，格式正常； 微信投诉单号：200298120220406100525162386；微信支付单号：4200001348202203036740973661；商户号：1520058051；问题图片对应历史协商记录流水号：300298120220406170526095864； ps. 下面截图中，上面一条meida_url是失败的，下面一条media_url是成功的。 [图片] ps.后台查询投诉协商历史记录（红框圈出的是显示失败的图片），证明了"存在同时上传两张图片，一张正常下载，另一张下载失败的情况" [图片] ps.下面是对应的c端显示截图 [图片] ps. 使用postman请求图片成功与失败截图： [图片] curl --location --request GET 'https://api.mch.weixin.qq.com/v3/merchant-service/images/ChsyMDAyOTgxMjAyMjAzMjgxODA1MTAzNTAyMDUSGzMwMDI5ODEyMDIyMDMyOTE0MDUxMTYzODUxOBgBINDb2JIGKAMwAjgB' \ --header 'Authorization: WECHATPAY2-SHA256-RSA2048 mchid="1520058051",serial_no="48169270ABF64B3FC91CBC60EBF2B9D8017D6F89",nonce_str="1649920239019",timestamp="1649920239",signature="uVdVx3xFjAY/mzkdgTe2GwBTyPnGC59ioDxZO+InnTg3EMUJ/ODbaCqjLSAPChWsB8+nMN/XapjCIp+PA6cWqrN+qkSbdBwp9uczXz1sFxfBiEpVEtGb26ByjRj7+SwtyxiUvPN2dJzqKM4m4H2h/eOkHSxTKvBHO2y6Nb0ujdiLdWm5xqEeCgi4hGpkNqjo+TYlmnQ69ia3JHSy2+EHjydcVGKe+X1WQtoEfe0UbQ7vOYSzq0mRggkspLuoZ2/8rJct6YVDMw+xNjeJF8fuYBOpvjmFWcijbfYc2XGmwV1Cdaiv/t73os+tiQntKXZ5C01/Ub7S4WnKvoLgVwKd5A=="' [图片] curl --location --request GET 'https://api.mch.weixin.qq.com/v3/merchant-service/images/ChsyMDAyOTgxMjAyMjA0MDYxMDA1MjUxNjIzODYSGzMwMDI5ODEyMDIyMDQwNzE0MDUyNzUzODg4MRgBIJuQupIGKAMwAjgB' \ --header 'Authorization: WECHATPAY2-SHA256-RSA2048 mchid="1520058051",serial_no="48169270ABF64B3FC91CBC60EBF2B9D8017D6F89",nonce_str="1649920208112",timestamp="1649920208",signature="xPxG9ER2hqZPV0g98pH4Rlb3ThrdRKftSkRkQBjv9MafKmTgYPcGx26wMlNeRHH2FDTQSl06gd3O5WeTsNiGZpqPCqmzXzlL1xqnnC7HLhDKcc1JEEqkxiUy1jO+fDXGBFuVYPqHcXZM+vvRrEkADNfdoYeACqoMgfpJy/juW3REKPVa8LwWvtEFDMzxg7PUitFn1e//FMFu1Ek4FfpM+fFzM93oIxkgJRhWcdzFzne2HiQtza4DmLMakq4239iUwW9QeESAiXMAsY5DdGZfJj8Nxt/erh7q6X6KZXVvPvHjhLdxopUhqHC0ZKqZKt5zy5Kqf46PaTDBzgprAt3W5Q=="' [图片] postman中安装了wechatpay-apiv3脚本

2022-03-16要查你调用的是哪个接口，对于要求ssl证书的接口，当没设置时，很容易在https建立连接之时就被断开连接了，respond 就啥都没有。

Http头Authorization值格式错误，请参考《微信支付商户REST API签名规则》?按照官方文档https://pay.weixin.qq.com/wiki/doc/apiv3/wechatpay/wechatpay4_0.shtml的步骤， 获取签名时，依然报 ‘Http头Authorization值格式错误，请参考《微信支付商户REST API签名规则》’。但是我觉得最离谱的是，把官网的命令复制下来执行后，依然报此错误，按理说是报数据错误，各非格式问题。有人员能解答一下吗？ [图片][图片] 以下是获取签名信息的代码，同样也是官方给的示例代码： public static void main(String[]args) throws Exception { //认证类型 String schema = "WECHATPAY2-SHA256-RSA2048"; String httpurl = "/v3/certificates"; String httpAuthorization = getAuthorization("GET", httpurl, ""); String curl = "curl https://api.mch.weixin.qq.com/v3/certificates -H 'Authorization: WECHATPAY2-SHA256-RSA2048 " + httpAuthorization + "'"; System.out.println(curl); } /** * 得到签名信息 * @param method * @param url * @param body * @return * @throws Exception */ public static String getAuthorization(String method, String url, String body) throws Exception { String nonceStr = StrUtil.generateNonceStr(); long timestamp = System.currentTimeMillis() / 1000; //获取签名串 String message = buildMessage(method, url, timestamp, nonceStr, body); System.out.println("签名串："+message); //得到签名 String signature = sign(message.getBytes("utf-8")); System.out.println("签名值："+signature); //五项签名信息，无顺序要求 String httpAuthorization = "mchid=\"" + MCHID_JDKJ + "\"," + "nonce_str=\"" + nonceStr + "\"," + "signature=\"" + signature + "\"," + "timestamp=\"" + timestamp + "\"," + "serial_no=\"" + MCHSERIALNO_JDKJ + "\"" ; System.out.println("httpAuthorization:" + httpAuthorization); return httpAuthorization; } /** * 获取签名值 * @param message * @return * @throws Exception */ public static String sign(byte[] message) throws Exception { Signature sign = Signature.getInstance("SHA256withRSA"); //# 示例：私钥存储在文件 // PrivateKey merchantPrivateKey = PemUtil.loadPrivateKey(new FileInputStream("D:\\test\\apiclient_key.pem")); PrivateKey merchantPrivateKey = getPrivateKey("D:\\test\\apiclient_key.pem"); sign.initSign(merchantPrivateKey); sign.update(message); return Base64.getEncoder().encodeToString(sign.sign()); } /** * 获取私钥。 * @param filename 私钥文件路径 (required) * @return 私钥对象 */ public static PrivateKey getPrivateKey(String filename) throws IOException { String content = new String(Files.readAllBytes(Paths.get(filename)), "utf-8"); try { String privateKey = content.replace("-----BEGIN PRIVATE KEY-----", "") .replace("-----END PRIVATE KEY-----", "") .replaceAll("\\s+", ""); KeyFactory kf = KeyFactory.getInstance("RSA"); return kf.generatePrivate( new PKCS8EncodedKeySpec(Base64.getDecoder().decode(privateKey))); } catch (NoSuchAlgorithmException e) { throw new RuntimeException("当前Java环境不支持RSA", e); } catch (InvalidKeySpecException e) { throw new RuntimeException("无效的密钥格式"); } } /** * 构造签名串 * 签名串一共有五行，每一行为一个参数。行尾以 \n（换行符，ASCII编码值为0x0A）结束，包括最后一行。如果参数本身以\n结束，也需要附加一个\n * HTTP请求方法\n * URL\n * 请求时间戳\n * 请求随机串\n * 请求报文主体\n * @param method * @param url * @param timestamp * @param nonceStr * @param body * @return * @throws Exception */ public static String buildMessage(String method, String url, long timestamp, String nonceStr, String body) { return method + "\n" + url + "\n" + timestamp + "\n" + nonceStr + "\n" + body + "\n"; } 最后生成的签名信息如下： [图片] 最后使用命令执行结果如下： [图片] 请问这是哪里的问题
2022-03-10谢邀，一般俺的做法是，把哨子再往前推个10多秒，让前端只看到50秒的倒计时，给后端腾出些时间去关单。
native压哨支付（订单到期前）咋办？比如，网页显示二维码后，每3秒往后端查询一次，设定该订单1分钟失效，第20次轮询（1分钟）时会发送命令关闭订单。 假设，第60秒用户支付成功，由于回调地址notify_url接收数据时已经是61秒，该笔订单已经被我关闭了，请问这事咋整？大家有什么思路？
2022-03-02谢邀，可以使用环境变量读取方式
后端的配置文件是怎么进行复写的呢？我写了个简单的spring项目，但是配置文件里有敏感信息，例如数据库密码等等，所以上传的时候配置文件写的是本地测试的URL以及密码，如何进行在发布以后在微信云托管里面对这一部分进行复写，复写成生产环境的数据库用户名密码。
