Body Rewrite

HTTP:body (offset, size)

Offset and size are optional.

If offset is missing, it will be set as zero.

If size is missing, it will be set as -1 which means the whole HTTP body.

Return string. The HTTP body will be returned.

Example:

when HTTP_REQUEST {
HTTP:collect()
}
    --This function will change "username:test" to "username:Test"
function username_first_char_uppercase(str)
       local str1 = str:sub(1, 9)
    local str2 = str:sub(10, 10)
    str2 = str2:upper()
    local str3 = str:sub(11, -1)
    return str1..str2..str3
    end
    when HTTP_DATA_REQUEST {
    local body_str = HTTP:body(0, 16)
    local body_new = body_str:gsub("username:[A-Za-z][A-Za-z0-9_]+", username_first_char_uppercase)
    debug("body old = %s, body new = %s\n", body_str, body_new)
    HTTP:set_body(body_new, 0, 16)
}

HTTP:set_body("body_str", offset, size)

Offset and size are optional.

If offset is missing, it will be set as zero.

If size is missing, it will be set as -1 which means the whole http body.

The body_str is the HTTP body. Now only the string type body is supported.

Return boolean: true/false.

Example

when HTTP_REQUEST {
    HTTP:collect()
}
--This function will change "username:test" to "username:Test"
    function username_first_char_uppercase(str)
    local str1 = str:sub(1, 9)
    local str2 = str:sub(10, 10)
    str2 = str2:upper()
    local str3 = str:sub(11, -1)
    return str1..str2..str3
end
when HTTP_DATA_REQUEST {
    local body_str = HTTP:body(0, 16)
    local body_new = body_str:gsub("username:[A-Za-z][A-Za-z0-9_]+", username_first_char_uppercase)
    debug("body old = %s, body new = %s\n", body_str, body_new) 
    HTTP:set_body(body_new, 0, 16)
}
