Return Error code: 401 unauthorized

Zookeeper Return Error code: 401 unauthorized indicates that the HTTP return code is unauthorized, And the account and password are not entered. Therefore, the solution is to directly carry the password in the http package. Use shell to generate base64 encoding for user and password

Encode the account admin and password admin information with base64 as ywrtaw46ywrtaw4 =.

$ echo -n admin：admin | base64YWRtaW46YWRtaW4=

You can also use the results to verify whether the account is admin and the password is admin.

$ echo -n YWRtaW46YWRtaW4= | base64 -d

admin：admin 

After obtaining the base64 encoded result, add the following in the HTTP format of the GET request:

Authorization: Basic YWRtaW46YWRtaW4=

The 401 error code problem can be solved.
