Nacos-sdk-go for Go client allows you to access Nacos service,it supports service discovery and dynamic configuration.
## Requirements
Supported Go version over 1.12
Supported Nacos version over 1.x
Supported Go version over 1.15
Supported Nacos version over 2.x
## Installation
Use `go get` to install SDK：
```sh
$ go get -u github.com/nacos-group/nacos-sdk-go
$ go get -u github.com/nacos-group/nacos-sdk-go/v2
```
## Quick Examples
* ClientConfig
```go
constant.ClientConfig{

UpdateThreadNum int // the number of goroutine for update nacos service info,default value is 20
NotLoadCacheAtStart bool // not to load persistent nacos service info in CacheDir at start time
UpdateCacheWhenEmpty bool // update cache when get empty service instance from server
Username string // the username for nacos auth
Password string // the password for nacos auth
LogDir string // the directory for log, default is current path
RotateTime string // the rotate time for log, eg: 30m, 1h, 24h, default is 24h
MaxAge int64 // the max age of a log file, default value is 3
LogLevel string // the level of log, it's must be debug,info,warn,error, default value is info
LogSampling *ClientLogSamplingConfig // the sampling config of log
ContextPath string // the nacos server contextpath
LogRollingConfig *ClientLogRollingConfig // the log rolling config
}
```
* ServerConfig
```go
constant.ServerConfig{
ContextPath string // the nacos server context path
Scheme string // the nacos server scheme,defaut=http,this is not required in 2.0
ContextPath string // the nacos server contextpath,defaut=/nacos,this is not required in 2.0
IpAddr string // the nacos server address
Port uint64 // the nacos server port
Scheme string // the nacos server scheme
Port uint64 // nacos server port
GrpcPort uint64 // nacos server grpc port, default=server port + 1000, this is not required
