Fastdfs Client (Python edition) guide

Recently done a distributed project with the Fastdfs, about Fastdfs here is not elaborated, interested in understanding of the small partners, please go to the official website: http://bbs.chinaunix.net/forum-240-1.html. Here we focus on the Fastdfs client (Python version), this version of the client has been used in the actual project, currently running stable. Project hosted in Git, Address: https://github.com/cosysun/FastDFSClient_Python.git.

First, the principle

Re-encapsulates the C + + interface on the basis of the official C + + client and provides the Python call

Second, the advantage

1, efficiency than the pure Python version of the higher

2, easy to maintain, with the official website C + + client update synchronization

3, good stability

Third, installation instructions

I use the installation environment is the CentOS 6.4 64bit, the specific steps are as follows:

1. Copy Clientforpython to Fastdfs source code client Directory

2. Copy the JSON library CP json/lib/*/usr/local/lib/ldconfig

Here is the JSON library I compiled under CentOS, there may be conflicts on other systems, please download the source code recompile, address: https://github.com/open-source-parsers/jsoncpp.git

3. Execute make on the Access client directory

Please note that makefile should be modified according to the FASTDFS installation directory.

Iv. Introduction of the interface

1, fdfs_init (parameter 1st log level) Initialize FASTDFS client

Parameter 1: String FASTDFS Client Profile directory, for example: "/etc/fdfs/client.conf"

Parameter 2: Shaping print Log level total seven levels

Log_emerg = 0log_alert = 1log_crit = 2log_err = 3log_warning = 4log_notice = 5log_info = 6log_debug = 7

2, Fdfs_download (parameter 1, parameter 2) Download the file

Parameter 1: The FASTDFS group name where the string is located for example: group2

Parameter 2: String specific storage path for example: m00/00/00/cgeizvrlv3sayjctaaasfwwtovg9432330

3, Fdfs_upload (parameter 1, parameter 2) upload file

Parameter 1: String file contents

Parameter 2: string file suffix default can be null ""

4, Fdfs_delete (parameter 1, parameter 2) Delete file

Parameter 1: The FASTDFS group name where the string is located for example: group2

Parameter 2: String specific storage path for example: m00/00/00/cgeizvrlv3sayjctaaasfwwtovg9432330

5, monitoring Fastdfs information

List_all_groups () monitor all group information

List_one_group ("IP Address") monitors specified IP information

List_storages ("group name", "IP Address") monitors the information in a group under storages and monitors all if IP is not empty.

V. Examples of Use

Please refer to test cases under the test directory
