Go Regex not matching
问题
我正在尝试从自定义有效载荷中提取一个JSON对象。
我的正则表达式在这里工作得很好：https://regex101.com/r/G5lBDC/1/
但是Go语言没有返回匹配结果。
re := regexp.MustCompile(`/payload:\\"(.+?)\\\\\\"\\\\/g`)
rawResponse := "version:1 response:<status:200 message:\"OK\" payload:\"{\\\"id\\\":\\\"ll2.card_4U45pAWUMCLhsu\\\",\\\"uid\\\":\\\"ll2.acc_727V8M6GjPJ9I26CqZHgxN\\\"}\\\"\\013\\022\\006ll2-cc\\032\\0019\" endorsement:<endorser:\"\\n\\007PASSKIT\\022\\224\\010>"
rawJSON := re.FindStringSubmatch(rawResponse)

你可以尝试这样做：（在这里运行）
package main
import (
"regexp"
"fmt"
)
func main() {
var re = regexp.MustCompile(`payload:\\"(\{[^\}]+\})`)
var str = `version:1 response:<status:200 message:\"OK\" payload:\"{\\\"id\\\":\\\"ll2.card_4U45pAWUMCLhsu\\\",\\\"uid\\\":\\\"ll2.acc_727V8M6GjPJ9I26CqZHgxN\\\"}\\\"\3\2\package main
import (
"regexp"
"fmt"
)
func main() {
var re = regexp.MustCompile(`payload:\\"(\{[^\}]+\})`)
var str = `version:1 response:<status:200 message:\"OK\" payload:\"{\\\"id\\\":\\\"ll2.card_4U45pAWUMCLhsu\\\",\\\"uid\\\":\\\"ll2.acc_727V8M6GjPJ9I26CqZHgxN\\\"}\\\"\\013\\022\\006ll2-cc\\032\\0019\" endorsement:<endorser:\"\\n\\007PASSKIT\\022\\224\\010>`
rawJSON := re.FindStringSubmatch(str)
fmt.Println(rawJSON[1])
}
