推荐一个Json解析库

推荐一个json库 gojson ，可以通过命令行 工具 根据输入的Struct动态生成 MarshalJSON/UnmarshalJSON 方法，性能与EasyJSON、Jsonparser、Jsoniter相比要好很多

GoJSON

GoJSON is a fast and easy package to marshal/unmarshal struct to/from json. You can use GoJSON tool to generate marshal/unmarshal code, in benchmark tests, GoJSON 's generate code is almost 6~7 times faster than encoding/json .

Example

# install
  go get -u -v github.com/go-fish/gojson
  cd ${GOPATH}/src/github.com/go-fish/gojson/cmd
  go build -o gojson main.go


# usage
  gojson [options] <input dir|file>
  
  -inline
        Use inline function in generate code (default true)
  -m string
        Mode of generate, eg: encode, decode, all (default "all")
  -o string
        Optional name of the output file to be generated. (default "gojson.generate.go")
  -unsafe
        Use decoder without copy data
  -version
        Show version information.

with -inline && -unsafe, you can get most performance generate code with -m, gojson will generate marshal/unmarshal/both for all expose structs in input dir/file.

For expose structs, gojson generate MarshalJSON/UnmarshalJSON methods for marshal/unmarshal json. You also can use gojson.Marshal/gojson.Unmarshal functions to marshal/unmarshal json.
