Python写的代码，用官网的验签工具是正确的，但一直报401：代码如下： def generate_signature(timestamp, nonce_str, body): signature_string = f"GET\n/v3/certificates\n{timestamp}\n{nonce_str}\n{body}\n" hash_message = SHA256.new(signature_string.encode('utf-8')) signature = pkcs1_15.new(private_key_pem).sign(hash_message) return base64.b64encode(signature).decode('utf-8') @app.route('/api/v0/create-order', methods=['POST']) def create_order(): result = request.json data = result.get('data') print('data:', data) description = data['description'] out_trade_no = data['out_trade_no'] total_fee = data['total_fee'] # 构建请求参数 params = { "appid": os.getenv('APP_ID'), "mchid": os.getenv('MCH_ID'), "description": description, "out_trade_no": out_trade_no, "notify_url": os.getenv('NOTIFY_URL'), "amount": { "total": total_fee, "currency": "CNY" } } # 生成请求头 timestamp = str(int(time.time())) nonce_str = generate_nonce_str() body='' signature = generate_signature(timestamp, nonce_str, body) # print('signature:', signature) headers = { "Authorization": f"WECHATPAY2-SHA256-RSA2048 mchid=\"{os.getenv('MCH_ID')}\",nonce_str=\"{nonce_str}\",signature=\"{signature}\",timestamp=\"{timestamp}\",serial_no=\"{os.getenv('CERT_SERIAL_NO')}\"", "Accept": "application/json", "Content-Type": "application/json" } # 发送请求 response = requests.post('https://api.mch.weixin.qq.com/v3/pay/transactions/native', headers=headers, data=json.dumps(params)) print('weixin_response:', response) if response.status_code == 200: code_url = response.json().get('code_url') order_status[out_trade_no] = '待支付' print('code_url:', code_url) return jsonify({'code_url': code_url, 'out_trade_no': out_trade_no,'code': 200}), 200 else: print('创建订单失败:', response.json) return jsonify({'error': '创建订单失败', 'response': response.json(),'code': 500}), 500
你好，麻烦通过点击下方“反馈信息”按钮，提供出现问题的。
401是签名问题，调用V3下单接口也不需要用到平台证书
