Hurl File

Character Encoding

Hurl file should be encoded in UTF-8, without byte order mark to the beginning (while Hurl ignores the presence of a byte order mark rather than treating it as an error)

File Extension

Hurl file extension is .hurl


Comments begins with # and continue until the end of line. Hurl file can serve as a documentation for HTTP based workflows so it can be useful to be very descriptive.

# A very simple Hurl file
# with tasty comments...
x-app: MY_APP  # Add a dummy header

HTTP/1.1 302   # Check that we have a redirection
header "Location" exists
header "Location" contains "login"  # Check that we are redirected to the login page

Special Characters in String

String can include the following special characters:

  • The escaped special characters " (double quotation mark), \ (backslash), \b (backspace), \f (form feed), \n (line feed), \r (carriage return), and \t (horizontal tab)
  • An arbitrary Unicode scalar value, written as \u{n}, where n is a 1–8 digit hexadecimal number

HTTP/1.1 200

# The following assert are equivalent:
jsonpath "$.slideshow.title" equals "A beautiful ✈!"
jsonpath "$.slideshow.title" equals "A beautiful \u{2708}!"

In some case, (in headers value, etc..), you will also need to escape # to distinguish from a comment. In the following example:

x-token: BEEF \#STEACK # Some somment
HTTP/1.1 200

We’re sending a header x-token with value BEEF #STEACK
