### 整体架构
> php调用id生成器，php 需要借助motan-agent实现rpc通信

![整体架构](https://gitee.com/man0sions/IdCreator/raw/master/doc/rpc-php.png)

> golang/java调用id生成器 对于golang/java，具备tpc长链接能力

![整体架构](https://gitee.com/man0sions/IdCreator/raw/master/doc/rpc-go.png)
### 算法
```
+--------------------------------------------------------------------------+
| 1 Bit Unused | 41 Bit Timestamp |  10 Bit NodeID  |   12 Bit Sequence ID |
+--------------------------------------------------------------------------+
雪花算法，每个node,每毫秒产生4096个唯一id

```


### 启动
```
//先修改config/mesh-confs/basic.yaml 的zk地址 address: "xxx.xxx.xxx.xxx:2181"
go run main.go --conf=config/main.yaml --pool=idcreator --nodeId=20
//nodeId-支持0-1023，启动后不要更改，否则会产生重复id
//pool-提供的motan服务配置
```



### http调用
>12核12G 下压测

![image](https://gitee.com/man0sions/IdCreator/raw/master/doc/qps.png)


```
curl http://127.0.0.1:8778/v1/IdCreator //本机localhost

返回值
{
"time": 1601191174,
"status": 10000,
"msg": "操作成功",
"data": "334011185131241472"
}

```
### motan-rpc调用

> 也可以参考tests/rpc_test.go 中的例子

> 1:在go.mod 中加入

```
replace (
	github.com/weibreeze/breeze-go => github.com/weibreeze/breeze-go v0.1.1
	go.uber.org/zap => github.com/uber-go/zap v1.9.1
)

```

> 2:vim main.go

```
package main

import (
	"gitee.com/man0sions/IdCreator/lib/tmotan"
	"log"
)

func main() {
	log.SetFlags(log.Lshortfile)
	client := tmotan.NewClient("./my_app.yaml")
	ret, err := client.CallIdCreator()
	log.Println(ret,err)
}


```


> 3:vim my_app.yaml 

```
motan-client:
  log_dir: motanlogs

motan-registry:
  zk-registry:
    protocol: zookeeper
    address: "127.0.0.1:2181"
    registrySessionTimeout: 10000


motan-basicRefer:
  basicRefer:
    group: test1
    protocol: motan2
    registry: zk-registry
    requestTimeout: 1000
    haStrategy: failover
    loadbalance: roundrobin
    serialization: simple
    filter: "accessLog"
    retries: 0

motan-refer:
  call_proxy:
    group: test1
    path: com.xxx.yyy.service.IdCreatorService
    registry: zk-registry
    basicRefer: basicRefer
    #    requestTimeout: 250
    retries: 1
```

> 4: vim build.sh

```
#!/bin/sh
unset GOPROXY
# go version

export "GOPROXY=https://goproxy.cn/,direct"

go get -insecure -v && CGO_ENABLED=0 go build -o my_app main.go

```

> 5: ./build.sh 编译

> 6: ./my_app 运行


### php 用法
> php 不能连zk发现节点，只能自己轮训,也可以自己配置motan-agent

```
    //先安装 https://github.com/weibocom/motan-php
    <?php
        define('D_AGENT_ADDR', '10.x.x.2:' . env('WEIBO_MESH_UG_PORT', 8841));

        $service = 'com.xxx.yyy.service.IdCreatorService';
        $group = 'test1';
        $remote_method = '/v1/IdCreator';
        $str = "";
        $params = [$str];
        $cx = new \Motan\MClient();
        $request = new \Motan\Request($service, $remote_method, $params);
        $request->setRequestId(1111);
        $request->setGroup($group);
        try {
            $res = $cx->doCall($request);
            var_dump($res);
        } catch (Exception $e) {
            var_dump($e->getMessage());
        }
```
