微信批次单号查询批次单API安装官网签名弄了，老是报下面的错
{"code":"SIGN_ERROR","detail":{"detail":{"issue":"sign not match"},"field":"signature","location":"authorization","sign_information":{"method":"GET","sign_message_length":132,"truncated_sign_message":"GET\n/v3/transfer/batches/batch-id/10300000711009999911?need_query_detail=true&offset=1\n16456745678\ngnua88y5mrnksd9bnfou5czi4475415kbemis\n\n","url":"/v3/transfer/batches/batch-id/10300000711009999911?need_query_detail=true&offset=1"}},"message":"错误的签名，验签失败"}
不知有没有老铁遇到过
同样的问题,研究了2天已解决，body主体改成空字符串就行了
请问，问题解决了吗？我也是同样的问题。
签名在发起API的POST时，就没问题。查询这个是GET。同样的签名方式。就错误了。
