Question

我正在运行curl来测试cookie

curl -v --cookie cookies.txt -b cookie_to_del http://localhost/

没有cookie_to_del文件出现，但在输出中我看到：

* Added cookie TestCookie="my+cookie+value" for domain localhost, path /, expire 0
< Set-Cookie: TestCookie=my+cookie+value

同样的方法，在cookies.txt中我有几个cookie而且看不到它们的设置。我的服务器有php命令print_r($_COOKIE);，我显示空数组。

怎么了？

--cookie和-b是等效的，它们只是指定要从中读取Cookie的文件。它不会创建或覆盖此文件。如果你多次给他们，只使用最后一次。

要保存Cookie，您必须使用--cookie-jar或-c。所以它应该是：

curl -v --cookie cookies.txt --cookie-jar cookie_to_del http://localhost

如果您想使用发回的Cookie更新原始Cookie，则可以在两个otions中使用相同的文件。

My `cookies.txt` file contains:

# Netscape HTTP Cookie File
# http://curl.haxx.se/rfc/cookie_spec.html
# This file was generated by libcurl! Edit at your own risk.

.bridgebase.com TRUE    /   FALSE   0   SRV www3

我做了：

$ curl -s -v --cookie cookies.txt --cookie-jar cookies_to_del http://www.bridgebase.com/vugraph/schedule.php >/dev/null
* About to connect() to www.bridgebase.com port 80 (#0)

如您所见，它发送了标题Cookie: SRV=www3，它从文件中读取。生成的cookies_to_del文件包含：

# Netscape HTTP Cookie File
# http://curl.haxx.se/rfc/cookie_spec.html
# This file was generated by libcurl! Edit at your own risk.

.bridgebase.com TRUE    /   FALSE   0   SRV www3
#HttpOnly_www.bridgebase.com    FALSE   /   FALSE   0   PHPSESSID   gu1fj84buirg370lee356b5r26

关于文件的格式，文档说：

从中读取cookie的文件的文件格式应该是纯HTTP标头或Netscape / Mozilla cookie文件格式。

我使用的文件是Netscape cookie文件。

curl没有cookie设置，没有cookie保存
