Javascript login using cURL in bash script

I am trying to write a bash script in which I need to log in to a site that uses javascript in its form. I have never used cURL, so any help would be appreciated. I know that I need to use cookies and I have http headers, but I don't know what I need to do with them.

Any help or pointing me in the right direction would be greatly appreciated. Thanks

From the request header, you can easily see that you are sending some data. But you didn’t. I give you a simple example of how an HTTP request can be converted to a curl command.

, , 2 var1 var2 POSTed http://www.example.com/form.url. :

POST /form.url HTTP/1.1
Host: www.example.com
Accept:  text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding: gzip, deflate
Content-Type: application/x-www-form-urlencoded; charset=UTF-8

var1=val1&var2=val2

,

curl -d 'var1=val1&var2=val2' \
--header 'Accept:  text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' \
--header 'Accept-Encoding gzip, deflate' \
--header 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' \
'http://www.example.com/form.url'

:

  • , . , . curl (, Host, User-Agent, Content-Type, Accept ..).

  • cookie, cookie.txt , -b cookie.txt -c cookie.txt . ,

    -b/--cookie <name=string/file> Cookie string or file to read cookies from (H)
-c/--cookie-jar <file> Write cookies to this file after operation (H)

  • -d switch , .

    -d/--data <data>   HTTP POST data (H)

http URL-:

  • POST
  • GET

GET URL-. URL-, :

http://foo.com/bar/barfoo/script.js?param1=this&param2=that&param3=the_other

URL- JavaScript http://foo.com/bar/barfoo/script.js. script :

  • param1= this
  • param2= that
  • param3= the_other

POST - URL-. - (, , ). --form curl, POST , , HTTP.

CURL:

-F/--form <name=content>
    (HTTP) This lets curl emulate a filled-in form in which a user has
    pressed the submit  button.  This  causes  curl  to  POST  data using
    the Content-Type multipart/form-data according to RFC 2388. This
    enables uploading of binary files etc. To force the 'content' part to
    be  a  file, prefix the file name with an @ sign. To just get the
    content part from a file, prefix the file name with the symbol <. The
    difference between @ and <  is  then  that  @  makes  a  file  get
    attached  in  the  post as a file upload, while the < makes a text
    field and just get the contents for that text field from a file.


Example, to send your password file to the server, where 'password' is the
name of  the  form- field to which /etc/passwd will be the input:

    curl -F password=@/etc/passwd www.mypasswords.com

To  read content from stdin instead of a file, use - as the filename. This
goes for both @ and < constructs.

You can also tell curl what Content-Type to use by using 'type=', in a
manner similar to:

    curl -F "web=@index.html;type=text/html" url.com

  or

    curl -F "name=daniel;type=text/foo" url.com

You can also explicitly change the name field of a file upload part by
setting filename=, like this:

    curl -F "file=@localfile;filename=nameinpost" url.com
