我的请求头Authorization中的signature属性：签名值错误，我用测试工具也试了签名值没有问题，可是已提交请求就返回签名值错误。 {"code":"SIGN_ERROR","detail":{"detail":{"issue":"sign not match"},"field":"signature","location":"authorization","sign_information":{"method":"POST","sign_message_length":1884,"truncated_sign_message":"POST\n/v3/applyment4sub/applyment/\n1603698983\n03a71333792f4a24a157ee5a191184f1\n{\"busine\n","url":"/v3/applyment4sub/applyment/"}},"message":"错误的签名，验签失败"} 微信返回的错误信息。
