How do I send spring csrf token from Postman rest client?

I have csrf protection in spring framework. So in each request I send csrf token in header from ajax call, which is perfectly working.

<meta name="_csrf" content="${_csrf.token}"/>
<meta name="_csrf_header" content="${_csrf.headerName}"/>

var token = $("meta[name='_csrf']").attr("content");
var header = $("meta[name='_csrf_header']").attr("content");

In ajax

beforeSend: function(xhr) {
                xhr.setRequestHeader(header, token),
                xhr.setRequestHeader("username", "xxxx1"),
                xhr.setRequestHeader("password", "password")
            }

I haven't any idea to generate csrf token and include in header section of Postman Rest Client ? Would you please help me to send csrf token from Postman Rest Client?

The Easiest way to do this consistently so you don't have to get the token each time:

NOTE:you need to install PostMan Interceptor and activate it to have access to the browsers cookies

1. Create a new environment so environment variables can be stored

2. Create a login method with a test to store the XSRF cookie in an environment variable, in the test tab post this code

   //Replace XSFR-TOKEN with your cookie name
   var xsrfCookie = postman.getResponseCookie("XSRF-TOKEN");
   postman.setEnvironmentVariable("xsrf-token", xsrfCookie.value);
   

EDIT For anyone using the 5.5.2 postman or later you will also have to decode the cookie, and they have also provided alternative ways to obtain cookies as @Sacapuces points out

pm.environment.set("xsrf-token", decodeURIComponent(pm.cookies.get("XSRF-TOKEN")))

Now you will have an environment variable with xsrf-token in it.

3. Save your login method

4. Create the new post you want to create and in the headers add your XSRF-Token-Header Key, and the environment variable in handle bars to access it{{}}

5. Now before running your new request make sure you run your login, it will store the environment variable, and then when you run the actually request it will automatically append it.

I am able to send REST with csrf token by following the steps below:

1. The CSRF token generated automatically by spring security when you logged in. It will be shown at the response header.

2. The CSRF token can be used on subsequent request by setting X-CSRF-TOKEN with CSRF token on header.

Firstly you need to install PostMan Interceptor and activate it to have access to the browsers cookies.

1. You have to fetch the CSRF Token by making a GET Request: Header: "XSRF-TOKEN" and Value: "Fetch"

2. You should see the Token in the cookie tab and can copy it (Notice: You can configure spring how the cookie should be named. Maybe your cookie has another name than "XSRF-TOKEN". Attention: You have the remove this blank char in the token from the newline)

3. Now make your POST Request and set the header to: Header: "X-XSRF-TOKEN" and Value: "Your copied Token without blanks"

For me works variant with adding X-CSRF-TOKEN to headers.

Please put X-CSRF-Token as key and FETCH as the value in the GET request header and you will receive the token in the response header

If you don't want to configure environment variables etc. here is the quickest solution

I've used csrfTokenRepository() to allow spring security to generate csrf token

@EnableWebSecurity
public class AppSecurityConfig extends WebSecurityConfigurerAdapter{
    @Override
    protected void configure(HttpSecurity http) throws Exception {
    // TODO Auto-generated method stub
    http.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
    // your code
    } 
}

After adding these lines of code, use GET request to generate csrf token. I've used postman and I got token in the response cookies section. Copy the token and use it in POST call.
