I am using curl to retrieve cookies like so:
curl -c cookies.txt url
then I parse the cookie I want from the cookies.txt file and send the request again with the cookie
curl -b "name=value" url
Is this the correct way to send the cookie?
Is there a simpler way?
You can use -b to specify a cookie file to read the cookies from as well.
In many situations using -c and -b to the same file is what you want:
curl -b cookies.txt -c cookies.txt http://example.com
Further
Using only -c will make curl start with no cookies but still parse and understand cookies and if redirects or multiple URLs are used, it will then use the received cookies within the single invoke before it writes them all to the output file in the end.
The -b option feeds a set of initial cookies into curl so that it knows about them at start, and it activates curl's cookie parser so that it'll parse and use incoming cookies as well.

The cookies file format apparently consists of a line per cookie and each line consists of the following seven tab-delimited fields:
domain - The domain that created AND that can read the variable.
flag - A TRUE/FALSE value indicating if all machines within a given domain can access the variable. This value is set automatically by the browser, depending on the value you set for domain.
path - The path within the domain that the variable is valid for.
secure - A TRUE/FALSE value indicating if a secure connection with the domain is needed to access the variable.
expiration - The UNIX time that the variable will expire on. UNIX time is defined as the number of seconds since Jan 1, 1970 00:00:00 GMT.
name - The name of the variable.
value - The value of the variable.

if you have Firebug installed on Firefox, just open the url. In the network panel, right-click and select Copy as cURL. You can see all curl parameters for this web call.
Very annoying, no cookie file exmpale on the official website https://ec.haxx.se/http/http-cookies.
Finnaly, I find it does not work, if your file content is just copyied like this
foo1=bar;foo2=bar2
I gusess the format must looks the style said by #Agustà Sánchez
. You can test it by -c to create a cookie file on a website.
So try this way, it works
curl -H "Cookie:`cat ./my.cookie`" http://xxxx.com
You can just copy the cookie from chrome console network tab.

I am now using Jmeter to prepare a test plan for my web. The rough flow of the script is that I can check my profile after login. I tried to run my recorded script, and found that the cookie is encoded in http format which I don't want it to be.
Therefore, I would like to ask is there anyway so that I can have a not encrypted cookie value?
[I applied a cookie manager in the script.
The value of the cookie now is something like "%22mh8eIAH8rfsZsM3r%22".
The value that I want is something like "mh8eIAH8rfsZsM3r"]
%22 means " which is percent-encoded, if you want to decode it back - take a look at __urldecode() function:
In general you should not be recording any cookies, you need to add a HTTP Cookie Manager and JMeter will automatically extract incoming cookies from Set-Cookie response header and add them to the next request as Cookie header if domain and path match the ones in the cookie, it's not expired, etc
If you need to access the cookie value as a JMeter Variable the easiest way is adding the next line to user.properties file:
CookieManager.save.cookies=true
and upon JMeter restart you will be able to use the cookie value as ${COOKIE_your-cookie-name-here}

I have created a cloudfront distribution and configured with restrict viewer access. So i'm just looking for a way to view the contents within the distribution by assigning the cookies. I've manage to generate the below signed cookies.
{
"CloudFront-Policy":
"CloudFront-Key-Pair-Id":
"CloudFront-Signature":
}
Can we just call the cloudfront destination(https://d1fzlamzw9yswb.cloudfront.net/17-Sep-201%3A05%3A48_1.jpg) in browser and test it whether it works by assigning cookies from browser? What is the best way to test whether the signed cookies are working or not?
I assume that you already created a signed cookie.
You can use curl to send cookies to your CloudFront distribution. This is one way of testing if your setup works correctly. Here is how to pass a cookie with your request:
curl -b 'session=session_id' https://yourdistribution.cloudfront.net
The full header that curl sets for this request looks like this Cookie: session=session_id
UPDATE:
Concretely, CloudFront will expect the following cookie set:
curl -v -X GET --output test-file -b "CloudFront-Expires=4762454400" -b "CloudFront-Signature=k9CxLm0HL5v6bx..." -b "CloudFront-Key-Pair-Id=APKA..." "https://yourdistribution.cloudfrontnet/test-file"
Alternatively, we can also use --cookie flag, like this:
curl -v -X GET --output test-file --cookie "CloudFront-Expires=4762454400;CloudFront-Signature=k9CxLm0HL5v6bx...;CloudFront-Key-Pair-Id=APKA..." "https://yourdistribution.cloudfrontnet/test-file"

I'm writing a Postman collection to be executed in Postman Runner, which requires that cookies from a first request be used in subsequent requests.
In curl, you can achieve this like so
curl -d "username=x&password=y" -c logincookie.txt https://service.com/login
curl -b logincookie.txt https://service.com/x/profile
I can't seem to do this in Postman.
As documented, in my test for the first request I save the cookie as an environment variable
var login_cookie = postman.getResponseCookie("LOGIN");
postman.setEnvironmentVariable("login_cookie", login_cookie);
and then, as described in this blog post, I add the following header to the subsequent request,
Cookie: {{login_cookie}}
but the server responds to this request as if the cookie was not provided.
How can I pass the cookie from the first response to the second request?
I'm using the Postman for Mac 4.10.7 and have enabled the interceptor with its default settings, although I don't know how to validate that this actually works!
After reading documentation and posts in Internet I still cannot solve the problem with Cookie Manager in jMeter.
I got sid ID in response header but it is not stored in my cookies manager.
Below are the screens of my test plan and response with connect.sid
Could you help to figure out what is wrong?
Response with cookie
Cookie is not stored
In order to be handled by JMeter (and web browsers as well) your cookie needs to be compliant with some policies i.e. domain and path should not clash with the current URL, expiration date should not be in the past (your cookie expiration date is 20:33, looking into the time at your machine you have 23:21), etc.
Also your set-cookie header name looks suspicious, I used to see it with first capital letters like Set-Cookie
Suggestions:
Try out different "Cookie Policy" options:
Add the next line to user.properties file (lives in JMeter's "bin" folder)
CookieManager.check.cookies=false
Points 2 and 3 don't help you can get some extra information by enabling debugging output by adding the next line to the aforementioned user.properties file:
log_level.jmeter.protocol.http.control=DEBUG
and look into jmeter.log file for anything connected with CookieManager, HC4CookieHandler or HC3CookieHandler
As a last resort you can always get any cookie value using Regular Expression Extractor, the relevant configuration would be something like:
I'm using Code::Blocks with MinGW, under Windows 7.
I'm writing a multithreaded web crawler with libcurl, using a CURLSH object with CURL_LOCK_DATA_COOKIE enabled to share cookies among different threads.
Once a handle receives a cookie, it is successfully shared among every other handle. However, I need to copy the initial set of cookies from Firefox or Chrome. I found that they store cookies using sqlite, and I've been able to read cookies from both of them from within my program. The problem is, how do I give these cookies to libcurl? Ideally, there should be some way to feed these cookies to my CURLSH object, so that they get distributed to every handle. I have found no such thing.
Following this document, I can try to save the cookies I read from my browser to a cookies.txt file, which reduces to finding a correspondence between the fields in the database used by Firefox/Chrome and the Netscape format.
Netscape uses the following format:
domain flag path secure expiration name value
The problem comes with the flag field. I don't know what to write there. Firefox uses the following fields (file cookies.sqlite, table *moz_cookies*), which correspond with the Netscape format as follows (is this correct?):
host ??? path isSecure expiry name value
Chrome uses the following fields (file Cookies, table cookies):
host_key ??? path secure expires_utc name value
So, to create this cookies.txt file, I'm only missing that flag field. The document linked above says:
flag - A TRUE/FALSE value indicating if all machines within a given domain
can access the variable. This value is set automatically by the
browser, depending on the value you set for domain.
Which doesn't really tell me what to write there.
However, writting a file and then reading it seems like unnecessary work, given that I'll first load the cookies from Firefox/Chrome in RAM, and I should be able to give them to libcurl directly without going through the hard drive. I've found the CURLOPT_COOKIE option, but it is missing some fields (namely, domain). Also, that option doesn't seem to save the cookies for posterior use. It looks like I would need to call it for every transaction with only the cookies of the corresponding domain (and what if these cookies get changed? I would not want to check for changes manually, given that libcurl can do that).
So, given that I have all my cookies from Firefox/Chrome in memory, how do I give them to libcurl? If the only option is to use a cookies.txt file, what should I write in the flag field?
I've found the answer, with CURLOPT_COOKIELIST (I was confusing it with CURLINFO_COOKIELIST, which can only be used to read cookies). Using CURLOPT_COOKIELIST, I can enter my cookies as HTTP headers, which do not need that flag field. I'll only need to give format to the date. It looks like specifying the cookies for any handle is enough to set them in the CURLSH object, because I can set them in one handle and read them any other handle.
