Go語言如何通過之前獲取的cookie發(fā)起獲取cookie值的請求和發(fā)起新的請求cookie這里的第一個帖子請求是在表單中生成一個變量[SID=pcmPXXx+fidX1xxxX1cuK; Path=/; HttpOnly; SameSite=Strict]" 但我無法將此 cookie 發(fā)送到另一個發(fā)布請求（出現(xiàn)錯誤）。帶有注釋的示例 go 文件package mainimport (  "fmt"  "log"  "strings"  "net/http"  "io/ioutil"  "net/http/cookiejar")var client http.Clientfunc init() {    jar, err := cookiejar.New(nil)    if err != nil {        log.Fatalf("Got error while creating cookie jar %s", err.Error())    }    client = http.Client{        Jar: jar,    }}func main() {  urlx := "http://localhost:8080/api/v2/auth/login"  methodx := "POST"  payloadx := strings.NewReader(`username=admin&password=strongadmin`)  client := &http.Client {  }  reqx, err := http.NewRequest(methodx, urlx, payloadx)  if err != nil {    fmt.Println(err)    return  }  reqx.Header.Add("Referer", "http://localhost:8080/")  reqx.Header.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Safari/537.36")  reqx.Header.Add("Content-type", "application/x-www-form-urlencoded; charset=UTF-8")  resx, err := client.Do(reqx)  if err != nil {    fmt.Println(err)    return  }  defer resx.Body.Close()  cookie := resx.Cookies()  fmt.Println(cookie)  bodyx, err := ioutil.ReadAll(resx.Body)  if err != nil {    fmt.Println(err)    return  }  fmt.Println(string(bodyx))  //second request start here // this var cookies is a dummy cookie that i manually written,// i need to replace the below variable 'cookies' to previously obtained variable 'cookie' without error  cookies := &http.Cookie{      Name: "SID",      Value: "PW16gD0Ja0OqixXeqpQle1WC/OK19tj+",      MaxAge: 300,  }  url := "http://localhost:8080/api/changes"  method := "POST"  payload := strings.NewReader(`json=%7B%data=valuex%22%3A%22300%22%7D`)  clientx := &http.Client {  }  req, err := http.NewRequest(method, url, payload)  if err != nil {    fmt.Println(err)    return  }}
