代码如下：

from fdfs_client.client import * # pip install fastdfs-client-py3
client = Fdfs_client(get_tracker_conf('tracker.conf'))
ret = client.upload_by_filename('test')
print(ret)

FastDFS的版本是最新的6.12（截至2024.05.15）

执行代码时，报错如下：

Traceback (most recent call last):
  File "/Users/mac10.12/trying/anywhere/dd.py", line 3, in <module>
    ret = client.upload_by_filename('test')
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    raise ResponseError(errmsg)
fdfs_client.exceptions.ResponseError: [-] Error: Tracker response length is invaild, expect: 40, actual: 70

原因见：上传文件报错：java.io.IOException: recv body length: 70 is not correct, expect length: 40 · Issue #679 · happyfish100/fastdfs · GitHub

解决：

方案一：升级依赖包（GitHub - waketzheng/fastdfs-client-python at 1.0.1）

pip install 'git+ssh://git@github.com/waketzheng/fastdfs-client-python@1.0.1#egg=fdfs-client'

升级成功后，重新执行代码，发现已经不再报错，能正常上传文件了 

方案二：改用fastdfs-client-python(需要Python3.10+)

# pip install fastdfs-client
from fastdfs_client import FastdfsClient
client = FastdfsClient('tracker.conf')
ret = client.upload_by_filename('test')
print(ret)

执行结果如下：

    "Group name": "group1",
    "Remote file_id": "group1/M00/00/00/eE0vIWZEkqGAObkhAAAZ4rQ0_gU1863.py",
    "Status": "Upload successed.",
    "Local file name": "kitty.py",
