Cookies without chocolate Chips
In the HTTP sense, a cookie was a name with an associated value. A server sends the name and value to the client, and expects it to get sent back on every subsequent request to the server That matches the particular conditions set. The conditions include the domain name and path match and that, the cookie hasn ' t become too old.
In HTTP, a cookie consists of name and value.
The server sends the name and value to the client and expects the client to accompany this information each time a child request is sent.
The cookie includes the domain name, path, and whether it expires.
In real-world cases, servers send new cookie to replace existing ones to update them. Server use cookie to ' track ' Users and to keep ' sessions '.
In fact, the server sends a new cookie to replace the old information.
The server tracks the user and keeps the session through cookies.
Cookies is sent from server to clients with the header Set-cookie:and they ' re sent from clients to servers with the Cook Ie:header.
When the server sends a Cookie to the client, it sends an HTTP header: Set-cookie
When the client sends cookie information to the server, it sends an HTTP header:
To just send whatever cookies want to a server, you can use the Curlopt_cookie to set a cookie as String like this:
You can send cookie information by setting the Curlopt_cookie property:
Curl_easy_setopt (Easyhandle, Curlopt_cookie, "NAME1=VAR1; NAME2=VAR2; ");
In many cases, which is not enough. You might want to dynamically save whatever cookie the remote server passes to you, and make sure those cookies is then Used accordingly on later requests.
In most cases, this does not meet the requirements.
You may need to save the cookie information sent remotely to the local
And a cookie is included in the next request.
One-to-do-a, is-to-save all headers-a plain file and when-you-make a request, your tell Libcurl to re Ad the previous headers to figure out which cookie to use. Set the header file to read the cookie from with Curlopt_cookiefile.
Another way is to save all the received headers into a file, and when the request is sent, let Libcurl read the file and take out the corresponding cookie information.
Use Curlopt_cookiefile to set the file for Libcurl read cookies.
The Curlopt_cookiefile option also automatically enables the cookie parser in Libcurl. Until The cookie parser is enabled, Libcurl would not parse or understand incoming cookies and they would just be ignored. However, when the parser is enabled the cookie would be understood and the cookie would be kept in memory and used Properl Y in subsequent requests if the same handle is used. Many times this is enough, and if not, has to save the cookie to disk at all. Note that the file is specify to Icurlopt_cookiefile (3) doesn ' t has to exist to enable the parser, so a common-to Ju St enable the parser and not read any cookies are to use the name of a file you know doesn ' t exist. The
and curlopt_cookiefile option causes Libcurl to automatically parse the cookie.
Unless the cookie parser is activated, Libcurl does not parse cookie information, but ignores it altogether.
Once the cookie parser is activated, the cookie information is automatically saved in memory and automatically used in the subsequent request
you can not save the cookie information to the disk
Note that curlopt_cookiefile (3 The specified file does not have to be present to activate the cookie analysis function,
so an Activation Cookie analyzer is commonly used to set a nonexistent file.
If You would rather the use existing cookie that you've previously received with your Netscape or Mozilla browsers, yo u can make libcurl with that cookie file as input. The curlopt_cookiefile is used for that too, as Libcurl would automatically find out what kind of file it is and Act accord ingly.
You can let Libcurl use a cookie file that was previously obtained using Netscape or a browser
is also used curlopt_cookiefile settings.
Perhaps the most advanced cookies operation Libcurl offers, is saving the entire internal cookies state back into a Netscape /mozilla formatted cookie file. We call the Cookie-jar. When you set a file name with Curlopt_cookiejar, that file name is created and all received cookies is stored in It when Curl_easy_cleanup is called. This enables cookie to get passed in properly between multiple handles without any information getting lost.
Perhaps Libcurl's biggest extension in terms of cookies is to save the entire internal cookie information to the Netscape/mozilla format.
We call him Cookie-jar.
When you set the Curlopt_cookiejar property to set a file,
The file is created, and after the Curl_easy_cleanup function is executed, all the received cookie information is stored in the file.
This allows all cookie information to be sent out at the appropriate time.
