# 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。
