Questions about go-curl's OPT_COOKIEJAR option
问题
在使用go-curl中的OPT_COOKIEJAR选项时，有没有办法检查工作是否完成？
如果运行下面的源代码，会出现在cookie下载完成之前执行ReadFile的问题。我想解决这个问题。
CommonSetopt(easy)
easy.Setopt(curl.OPT_VERBOSE, 0)
easy.Setopt(curl.OPT_COOKIEJAR, cookieName)
easy.Setopt(curl.OPT_URL, string("https://drive.google.com/uc?export=download&id="+gdriveID))
log.Println("start download cookie: ", url)
if err := easy.Perform(); err != nil {
log.Println("cookie download fail: ", err)
return
}
readBuf, err := ioutil.ReadFile(cookieName)
if err != nil {
log.Println("cookie read fail: ", err)
return
}

When using the OPT_COOKIEJAR option in go-curl, is there a way to check whether the work is completed?
If you run the source code below, there is a problem that ReadFile is executed before the cookie download is completed. I want to solve this.
CommonSetopt(easy)
easy.Setopt(curl.OPT_VERBOSE, 0)
easy.Setopt(curl.OPT_COOKIEJAR, cookieName)
easy.Setopt(curl.OPT_URL, string("https://drive.google.com/uc?export=download&id="+gdriveID))
log.Println("start download cookie: ", url)
if err := easy.Perform(); err != nil {
log.Println("cookie download fail: ", err)
return
}
readBuf, err := ioutil.ReadFile(cookieName)
if err != nil {
log.Println("cookie read fail: ", err)
return
}

你需要在easy.Perform之后立即清理会话，而不是使用defer语句进行清理。
CommonSetopt(easy)
easy.Setopt(curl.OPT_VERBOSE, 0)
easy.Setopt(curl.OPT_COOKIEJAR, cookieName)
easy.Setopt(curl.OPT_URL, string("https://drive.google.com/uc?export=download&id="+gdriveID))
log.Println("开始下载cookie: ", url)
if err := easy.Perform(); err != nil {
log.Println("cookie下载失败: ", err)
easy.Cleanup()
return
}
// 进行清理
easy.Cleanup()
readBuf, err := ioutil.ReadFile(cookieName)
if err != nil {
log.Println("cookie读取失败: ", err)
return
}
英文:
You need to cleanup the session immediately after easy.Perform instead of cleaning up using a defer statement
CommonSetopt(easy)
easy.Setopt(curl.OPT_VERBOSE, 0)
easy.Setopt(curl.OPT_COOKIEJAR, cookieName)
easy.Setopt(curl.OPT_URL, string("https://drive.google.com/uc?export=download&id="+gdriveID))
log.Println("start download cookie: ", url)
if err := easy.Perform(); err != nil {
log.Println("cookie download fail: ", err)
easy.Cleanup()
return
}
// do cleanup
easy.Cleanup()
readBuf, err := ioutil.ReadFile(cookieName)
if err != nil {
log.Println("cookie read fail: ", err)
return
}
