I have modified the code according to your comments.
Also, I noticed the compile failed on Windows x86 platforms. I will check it later.

I have fixed the compile problem in Windows x86 platforms.

But I found that the Client/getPartitionsForTopic test will fail in the CI environment due to an unexpected extra item that duplicates the topic name in the returned result, it does not happened in my device, this may be related to the Pulsar version in the CI environment, which is 2.10.2, and i use pulsar 2.11.x.
I need some assistance to resolve this issue, thx.

Maybe the request body format is invalid. Will cause the partition topic to create failed.

1. You should assert the HTTP response code.
2. You should be change request body format:

-          data: '4',
+          data: 4,
