curl cookie处理 [英] Curl cookie handling

问题描述

有可能cURL不是每个用户都使用相同的cookie吗？

因为很酷，我存储我获得的cookie，但这个cookie将被使用

服务器看到请求并询问这个客户端是否向我发送了一个Cookie？

看到一个Cookie，然后发送回一个响应，并发送一个Cookie

客户端

下次客户端向同一个服务器发出请求时，它会沿着同一个cookie发送

伺服器看到这项要求，并询问「这位客户是否向我发送了Cookie？ >

伺服器这次看到Cookie，因为Cookie中有什么，所以做了一些不同的处理，然后传回回应，并附上Cookie

客户端（浏览器）看到响应，并说看起来，一个cookie为我，更新我有一个

听起来你遇到的问题是你有多个curl请求从同一台机器运行，但你想要每个人使用不同的cookie文件。

您应该能够通过使用以下两个curl选项来实现这一点。

  CURLOPT_COOKIEJAR //告诉curl哪个文件保存cookie从
 CURLOPT_COOKIEFILE //告诉curl要查找哪个文件并作为请求cookie发送
  

如果您设置系统以使每个不同的curl请求为这两个选项设置不同的路径值，则应设置。

Is that possible that with cURL not every user use the same cookie?

Because it's cool that I store the cookie that I get, but this cookie will be used by everybody, and it should be, because it's a login cookie.

解决方案

Here's a really basic overview of how cookies work

1. Client (browser) makes request

2. Server sees request and asks "hey, did this client send me a cookie?"

3. Server doesn't see a cookie, so it does some stuff, and then sends back a response, with a cookie

4. Client (browser) sees the response and says "hey look, a cookie for me, I better save this"

5. The next time the client makes a request to that same server, it sends along that same cookie

6. Server sees the request and asks "hey, did this client send me a cookie?"

7. Server sees the cookie this time, and does some different stuff because of what's in the cookie, and then sends back a response, with a cookie

8. Client (browser) sees the response and says "hey look, a cookie for me, lets update the one I have"

It sounds like the problem you're running into is you have multiple curl requests running from the same machine, but you want each one to use a different cookie file.

You should be able to achieve this by using the following two curl options

CURLOPT_COOKIEJAR   //tells curl which file to save the cookie from the server in
CURLOPT_COOKIEFILE  //tells curl which file to look in and send as the request cookie

If you setup a system so that each different curl request is setting a different path value for these two options, you should be set.
