Trying to accomplish the following output with my data:
- Convert to JSON string and write to file: output.json (this part is working)
- Gzip Compress the JSON string and write that to a json.gz file: output.json.gz (NOT WORKING)
The code runs fine and writes to both files. But the gzipped file gives this error when I try to unzip it: Data error in 'output.json'. File is broken
Here's the code:
package main
import (
"bytes"
"compress/gzip"
"encoding/json"
"fmt"
"io/ioutil"
)
type Generic struct {
Name string
Cool bool
Rank int
}
func main() {
generic := Generic{"Golang", true, 100}
fileJson, _ := json.Marshal(generic)
err := ioutil.WriteFile("output.json", fileJson, 0644)
if err != nil {
fmt.Printf("WriteFileJson ERROR: %+v", err)
}
var fileGZ bytes.Buffer
zipper := gzip.NewWriter(&fileGZ)
defer zipper.Close()
_, err = zipper.Write([]byte(string(fileJson)))
if err != nil {
fmt.Printf("zipper.Write ERROR: %+v", err)
}
err = ioutil.WriteFile("output.json.gz", []byte(fileGZ.String()), 0644)
if err != nil {
fmt.Printf("WriteFileGZ ERROR: %+v", err)
}
}
What did I miss?
