# ip2region xdb golang 生成实现
|
||
|
||
# 程序编译
|
||
通过如下方式编译得到 dbmaker 可执行程序:
|
||
```
|
||
# 切换到golang maker 根目录
|
||
cd ./
|
||
go build
|
||
```
|
||
编译成功后会在当前目录生成一个 dbmaker 的可执行文件
|
||
|
||
# 数据生成
|
||
|
||
通过 `dbmaker gen` 命令生成 ip2region.xdb 二进制文件:
|
||
```
|
||
➜ golang git:(v2.0_xdb) ✗ ./dbmaker gen
|
||
dbmaker gen [command options]
|
||
options:
|
||
--src string source ip text file path
|
||
--dst string destination binary db 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：
|
||
```bash
|
||
./dbmaker 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
|
||
...
|
||
2022/06/16 16:38:48 maker.go:317: write done, with 13804 data blocks and (683591, 720221) index blocks
|
||
2022/06/16 16:38:48 main.go:89: Done, elapsed: 33.615278847s
|
||
```
|
||
|
||
# 数据查询
|
||
|
||
通过 `dbmaker search` 命令来测试查询输入的 ip：
|
||
```
|
||
dbmaker test [command options]
|
||
options:
|
||
--db string ip2region binary db file path
|
||
```
|
||
|
||
例如，使用自带的 xdb 文件来运行查询测试：
|
||
```bash
|
||
./dbmaker search --db=../../data/ip2region.xdb
|
||
ip2region 2.0 test program, commands:
|
||
loadIndex : load the vector index for search speedup.
|
||
clearIndex: clear the vector index.
|
||
quit : exit the test program
|
||
ip2region>> 103.192.227.215
|
||
{region:中国|0|香港|0|0, iocount:8, took:87.151µs}
|
||
ip2region>> loadIndex
|
||
vector index cached
|
||
ip2region>> 39.114.2.16
|
||
{region:韩国|0|0|0|SK宽带, iocount:2, took:50.005µs}
|
||
ip2region>> 120.24.130.96
|
||
{region:中国|0|广东省|深圳市|阿里云, iocount:2, took:32.805µs}
|
||
ip2region>>
|
||
```
|
||
|
||
# bench 测试
|
||
|
||
如果你自主生成了 xdb 文件，请确保运行如下的 `dbmaker bench` 命令来确保制定的 xdb 文件的正确性：
|
||
```
|
||
➜ golang git:(v2.0_xdb) ✗ ./dbmaker bench
|
||
dbmaker 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：
|
||
```bash
|
||
./dbmaker 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: 52.200116397s}
|
||
```
|
||
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。
