# ip2region xdb python 生成实现
|
||
|
||
|
||
# 脚本执行
|
||
|
||
```
|
||
# 切换到python maker 根目录
|
||
> python main.py
|
||
ip2region xdb maker
|
||
main.py [command] [command options]
|
||
Command:
|
||
gen generate the binary db file
|
||
search binary xdb search test
|
||
bench binary xdb bench test
|
||
```
|
||
|
||
# `xdb` 数据生成
|
||
|
||
通过 `python main.py gen` 命令生成 ip2region.xdb 二进制文件:
|
||
```
|
||
➜ python git:(v2.0_xdb) ✗ python main.py gen
|
||
main.py gen [command options]
|
||
options:
|
||
--src string source ip text file path
|
||
--dst string destination binary xdb file path
|
||
```
|
||
|
||
例如，使用默认的 data/ip.merge.txt 作为源数据，生成一个 ip2region.xdb 到当前目录：
|
||
```
|
||
➜ python git:(v2.0_xdb) ✗ python main.py gen --src=../../data/ip.merge.txt --dst=./ip2region.xdb
|
||
# 会看到一堆输出，最终会看到类似如下输出表示运行结束
|
||
...
|
||

|
||
2022-07-13 19:58:00,540-root-63-INFO - Done, elapsed: 3m3s
|
||
```
|
||
|
||
|
||
# `xdb` 数据查询
|
||
|
||
通过 `python main.py search` 命令来测试查询输入的 ip：
|
||
```
|
||
➜ python git:(v2.0_xdb) ✗ python main.py search
|
||
main.py search [command options]
|
||
options:
|
||
--db string ip2region binary xdb file path
|
||
```
|
||
|
||
例如，使用自带的 xdb 文件来运行查询测试：
|
||
```
|
||
➜ python git:(v2.0_xdb) ✗ python main.py search --db=./ip2region.xdb
|
||
ip2region xdb search test program, commands:
|
||
loadIndex : load the vector index for search speedup.
|
||
clearIndex: clear the vector index.
|
||
quit : exit the test program
|
||

# bench 测试
|
||
|
||
如果你自主生成了 `xdb` 文件，请确保运行如下的 `python main.py bench` 命令来确保生成的的 `xdb` 文件的正确性：
|
||
```
|
||
➜ python git:(v2.0_xdb) ✗ python main.py bench
|
||
main.py bench [command options]
|
||
options:
|
||
--db string ip2region binary xdb file path
|
||
--src string source ip text file path
|
||
--ignore-error bool keep going if bench failed
|
||
```
|
||
|
||
例如：使用 data/ip.merge.txt 源文件来 bench 测试 data/ip2region.xdb 这个 xdb 文件：
|
||
```
|
||
➜ python git:(v2.0_xdb) ✗ python main.py bench --db=../../data/ip2region.xdb --src=../../data/ip.merge.txt
|
||
# 会看到一堆输出，看到类似如下的数据表示 bench 测试通过了，否则就会报错
|
||
...
|
||
try to bench segment: `{}` 224.0.0.0|255.255.255.255|0|0|0|内网IP|内网IP
|
||
|-try to bench ip '224.0.0.0' ... --[Ok]
|
||
|-try to bench ip '231.255.255.255' ... --[Ok]
|
||
|-try to bench ip '239.255.255.255' ... --[Ok]
|
||
|-try to bench ip '247.255.255.255' ... --[Ok]
|
||
|-try to bench ip '255.255.255.255' ... --[Ok]
|
||
Bench finished, [count: 3417955, failed: 0, took: 88.061s]
|
||
```
|
||
*请注意 bench 测试使用的 `src` 文件需要是对应的生成 ip2region.xdb 的源文件相同*。
|
||
如果运行过程中有错误会立马停止运行，也可以执行 --ignore-error=true 参数来忽略错误，在最后看 failed 的统计结果。
