我调用的是商家转账接口https://api.mach.weixin.qq.com/v3/fund-app/mch-transfer/transfer-bills

以下是我的请求参数及header参数

'Authorization: WECHATPAY2-SHA256-RSA2048 mchid="1713241818",nonce_str="09RKDZRFH8SJEVQNKMK88ZT83KTOPLJZ",timestamp="1764658938",serial_no="7D6AA9465E7DA159F8F0CE28AF0E3E5FF77FDEFC",signature="HYx1S2ye0vJdn3RtERdBuxA1sCDGhVNsPRRwHVanPLWcFqxplc5lGxUiuhI2GL7gf7YXnHeciN712oxtWlWK5AyuTR+iQnz9eF3QarBimqAEMUX8ps9xwWI5+LlPKiz5d8ltUfJZ3DnwwcVfOWQ4O1Ir8+eVkR1RkASN4CoEJHdvAU5kIIKSUr+ixyCBtge3ULYd1bsKMUhDrM6go609Uq5/XRAHUbx6aQghVMfmvtQG6whBZRoCJXrsgt5JuIIh9ZuQZwOpCv4gf81RWKZwbiUmcz1qwqV/v5SwUSLk3xmXIa+g58d9aHG3ZdAsmHkIkFSstbhiak0fZzse7wwplQ=="',

'Accept: application/json',

'Content-Type: application/json'

{"appid":"wx4dd078ef20ad2aa2","openid":"o_oYe6p1TrU3CPUbpraF9CfQwObc","out_batch_no":"test111","total_amount":"30","transfer_remark":"云AXXXX提现","transfer_scene_id":"1000","transfer_scene_report_infos":[{"info_type":"活动名称","info_content":"活动奖励"},{"info_type":"奖励说明","info_content":"活动奖励"}]}

但是在请求过程中接口直接返回了false 搜索各网站都说大概率是加签出了问题 也就是Authorization字段不对 但是我在代码中使用文档的字段签名发现结果是对的(签名过程应该没错) 请问各位大佬要怎么解决这个问题 已经困扰一整天了
