我在调用微信商家转账的时候,为什么总是提示错误的签名,验签失败呢? 我的微信退款都是正常的, 这个是我请求签名的body 很疑惑啊! { "transfer_scene_report_infos" : [ { "info_type" : "活动名称", "info_content" : "团长佣金提现" }, { "info_type" : "奖励说明", "info_content" : "业务推广佣金" } ], "transfer_amount" : 20, "openid" : "oejHs6y1_bptfZN4WJH2122222222222222222kzr8w", "appid" : "wxf431cd56222222222ae5d", "out_bill_no" : "456213978", "user_recv_perception" : "现金营销", "transfer_scene_id" : "1000", "transfer_remark" : "openId" } public String getToken(String method, HttpUrl url, String body) throws SignatureException, NoSuchAlgorithmException, InvalidKeyException, UnsupportedEncodingException { String nonceStr = WXPayUtil.generateNonceStr(); //WXPayUtil是微信支付自带的sdk long timestamp = System.currentTimeMillis() / 1000; //生成时间戳 //需要加密的参数 String canonicalUrl = url.encodedPath(); if (url.encodedQuery() != null) { canonicalUrl += "?" + url.encodedQuery(); } String parameter = method + "\n" + canonicalUrl + "\n" + timestamp + "\n" + nonceStr + "\n" + body + "\n"; //对参数进行加密 byte[] bytes = parameter.getBytes(StandardCharsets.UTF_8); Signature sign = Signature.getInstance("SHA256withRSA"); PrivateKey privateKey = PemUtil.loadPrivateKeyFromPath(ConstantPropertiesUtils.PEM); //privateKeyPath是商户证书密钥的位置apiclient_key.pem sign.initSign(privateKey); //商户密钥文件路径 sign.update(bytes); String signature = Base64.getEncoder().encodeToString(sign.sign()); //获取token String token = "mchid=\"" + ConstantPropertiesUtils.PARTNER + "\"," //商户号 + "nonce_str=\"" + nonceStr + "\"," + "timestamp=\"" + timestamp + "\"," + "serial_no=\"" + ConstantPropertiesUtils.MERCHANT + "\"," //merchantSerialNumber是微信支付中申请的证书序列号 + "signature=\"" + signature + "\""; String schema = "WECHATPAY2-SHA256-RSA2048 "; //注意有一个空格 return schema + token; } {"code":"SIGN_ERROR","detail":{"detail":{"issue":"sign not match"},"field":"signature","location":"authorization","sign_information":{"method":"POST","sign_message_length":414,"truncated_sign_message":"POST\n/v3/fund-app/mch-transfer/transfer-bills\n1737012721\na1bb4289f3e3472c8bb4a3085824218e\n{\"transf\n","url":"/v3/fund-app/mch-transfer/transfer-bills"}},"message":"错误的签名，验签失败"}

进件特约商户突然不能申请了 [图片]

微信订单号（transaction_id）是正确的

[图片][图片] Client error: `POST https://api.mch.weixin.qq.com/v3/fund-app/mch-transfer/transfer-bills` resulted in a `400 Bad Request` response: {"code":"PARAM_ERROR","message":"需传入转账场景报备信息，请检查"} 传入了还说没传

官方源码中还没有封装这个功能的service,所以用的自定义httpclient [图片] 商家中间已经有这个订单的流水,但是接口报错,报错的返回体内有这个订单的所有信息,就是文档的正常返回体,这个是为什么 [图片]

[图片] [图片] 已经配置了IP，为什么提示不允许调用呢？

微信支付分，免押金、免预付费、先享后付 有金额限制吗

现在基于老公众号已对部份客户进行签约绑定，需要将老公众号下线，绑定新公众号，但是商户号不变，这样在绑定老公众号时已签约的客户能否在切换到新公众号后成功进行划扣
