Here is what I have tried.
type product struct {
ID int `json:"id"`
Description string `json:"description"`
Price float64 `json:"price"`
Bin string `json:"bin"`
Qoh int `json:"qoh"`
}
// ********* function to save data to a file *********//
func saveBackup(w http.ResponseWriter, r *http.Request) {
type Resp struct {
Message string `json:"message"`
Affected string `json:"affected"`
}
resp:= Resp{}
for k, v := range r.URL.Query() {
kee = k
val = v[0]
}
fileName := val // r.FormValue("filename")
bodyBytes, err := ioutil.ReadAll(r.Body)
var items product
json.Unmarshal(bodyBytes, &items)
fmt.Printf("%+v\n",items)
f, err := os.Create(fileName)
if err != nil {
fmt.Println(err)
return
}
l, err := f.Write(bodyBytes)
if err != nil {
fmt.Println(err)
f.Close()
return
}
fmt.Println(l, "bytes written successfully")
err = f.Close()
if err != nil {
fmt.Println(err)
return
}
resp.Message = "Save successful"
resp.Affected = "Saved"
respondWithJSON(w, http.StatusOK, resp)
}
//******** Retrieving the file ********** //
func getBackup(w http.ResponseWriter, r *http.Request) {
kee := ""
fileName := ""
for k, v := range r.URL.Query() {
kee = k
fileName = v[0]
}
var lines []product <=== []string - had this prior to scan Text
file, err := os.Open(fileName)
if err != nil {
log.Fatal(err)
}
defer func() {
if err = file.Close(); err != nil {
log.Fatal(err)
}
}()
// scanner := bufio.NewScanner(file)
// for scanner.Scan() {
// lines = append(lines, scanner.Text())
// }
b, err := ioutil.ReadFile(file)
append(lines, b) <== I know this is wrong
response, _ := json.Marshal(lines)
w.Header().Set("Content-Type", "application/json")
w.WriteHeader(http.StatusOK)
w.Write(response)
}
How can I return the result as a JSON file to the requesting application?
The client application parses the result to load into an array.
