I've got a log file, where each line is a JSON. Due to some Nginx security reasons, the logs are being saved in a hexadecimal format (e.g. the char " will be converted to \x22). Here is an example of a JSON line:
我有一个日志文件，其中每一行都是JSON。由于一些Nginx安全原因，日志以十六进制格式保存（例如，char“将转换为\ x22）。以下是JSON行的示例：
{ "body_bytes_sent": "474", "params": {\x22device_id\x22: \x221234567890\x22} }
My goal:
我的目标：
- Read the file line by line.
- 逐行读取文件。
-
Convert each line to a readable format
将每一行转换为可读格式
{ "body_bytes_sent": "474", "params" : {"device_id": "1234567890"} } -
Convert this string into a JSON object so I could manipulate it.
将此字符串转换为JSON对象，以便我可以操作它。
Any help will be appreciated.
任何帮助将不胜感激。

You can use strconv.Unquote to convert the string to a normal one:
您可以使用strconv.Unquote将字符串转换为普通字符串：
package main
import (
"encoding/json"
"fmt"
"strconv"
)
func main() {
// this is what your input string looks like...
qs := "{\\x22device_id\\x22: \\x221234567890\\x22}"
// now let's convert it to a normal string
// note that it has to look like a Go string literal so we're
// using Sprintf
s, err := strconv.Unquote(fmt.Sprintf(`"%s"`, qs))
if err != nil {
panic(err)
}
fmt.Println(s)
// just for good measure, let's see if it can actually be decoded.
// SPOILER ALERT: It decodes just fine!
var v map[string]interface{}
if err := json.Unmarshal([]byte(s), &v); err != nil {
panic(err)
}
fmt.Println(v)
}
