用微信提供的证书签名，验签工具测试，都提示验签通过。但是请求接口一直报错，提示签名错误。不清楚什么原因。 我是用Node.js开发的 {"code":"SIGN_ERROR","detail":{"detail":{"issue":"sign not match"},"field":"signature","location":"authorization","sign_information":{"method":"POST","sign_message_length":282,"truncated_sign_message":"POST\n/v3/pay/transactions/app\n1640873114\nc20a1e033595b6ca346333741c23beb6\n{\"appid\"\n","url":"/v3/pay/transactions/app"}},"message":"签名错误，请检查后再试"} }
