查询订单接口,不识别的参数fee_type?大家有遇到过吗
如题,调用查询订单接口的时候,一直返回 {"return_msg":"不识别的参数fee_type","return_code":"FAIL"}, 请求的参数: { "nonce_str": "653f82e6adba495581e324ea29670fe3", "out_trade_no": "********", "appid": "xxxxx", "sign": "********", "fee_type": "CNY", "mch_id": "160478***4", "sign_type": "HMAC-SHA256" }
