## 安装
`go get github.com/json-iterator/go`
## 使用
> 总之只需要在最前加上一行 `var json = jsoniter.ConfigCompatibleWithStandardLibrary` 即可
old
```
import "encoding/json"
json.Marshal(&data)
```
new
```
import "github.com/json-iterator/go"
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Marshal(&data)
```
---
old
```
import "encoding/json"
json.Unmarshal(input, &data)
```
new
```
import "github.com/json-iterator/go"
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Unmarshal(input, &data)
```
