retrieve hash from the file in ruby

Question

I have scenario as, I have stored a hash value in the abc file.

Here is my abc file

{
    "access_key"=>"XXXXXXXXXXXXXXXXXXX", 
    "secret_access_key"=>"XXXXXXXXXXXXXXXXXXX",  
    "bucket"=>"XXXXXXXXXXXXXXXXXXX", 
    "name_prefix"=>"my_videos/178/4406/", 
    "x-amz-security-token"=>"AQoDYXdzEBQa4AK5TxvWJM/xsONxl/9ZDVxJc0s9CY+A/yrbhF7/3fK8ZWxlEibuMiEGEzzJ+UcfXBKdOu7oJR2X8l9HqhAD5JmZ2+JJuZjVG9hqP1RPkoQysxXBCeGdOVqOSPk0kW/5sPUG4bjiBbP8WGR9ibRkEq3tGfYazC//UuAZIJDUe+R8FSZay2Izx8BZj3XwPWjF3DsSaWcTIbsRQlMlEmQHD6n7BDv022hNfX13Zf4U18lzft8Sv98etslTC3pbmRd6AbM1I6rK6hn6fJKmrcHYHD3OCAcC2JDWzsv270gBzv1wY4Uma3fU/3HapMIQ5Xb7TU7hlhdHDYjo76FgPRLUPTnw9bXKuWHjG9LVONJuu1aqymlY9iEwASq7Ugk/8w6IMGsRxSeFlbhI689HThukObsQKCpUk2URQwL21fu7/fExUWA5pU5LPwvDgxo0V4Q7JplNwdnXS62Dt3PEj/DmuxfXIM3mjZsF", 
    "expires"=>1999196123
}

now I have to retrieve that hash. So that I can read the file and get value of access_key, name_prefix.

How can I do this in ruby?

Answer 1

Do not store it like this. Store it in a yaml file:

access_key: XXXXXXXXXXXXXXXXXXX 
secret_access_key: XXXXXXXXXXXXXXXXXXX
bucket: XXXXXXXXXXXXXXXXXXX 
name_prefix: my_videos/178/4406/ 
x-amz-security-token: AQoDYXdzEBQa4AK5TxvWJM/xsONxl/9ZDVxJc0s9CY+A/yrbhF73fK8ZWxlEibuMiEGEzzJ+UcfXBKdOu7oJR2X8l9HqhAD5JmZ2+JJuZjVG9hqP1RPkoQysxXBCeGdOVqOSPk0kW/5sPUG4bjiBbP8WGR9ibRkEq3tGfYazC/UuAZIJDUe+R8FSZay2Izx8BZj3XwPWjF3DsSaWcTIbsRQlMlEmQHD6n7BDv022hNfX13Zf4U18lzft8Sv98etslTC3pbmRd6AbM1I6rK6hn6fJKmrcHYHD3OCAcC2JDWzsv270gBzv1wY4Uma3f/3HapMIQ5Xb7TU7hlhdHDYjo76FgPRLUPTnw9bXKuWHjG9LVONJuu1aqymlY9iEwASq7Ugk/8w6IMGsRxSeFlbhI689HThukObsQKCpUk2URQwL21fu7/fExUWA5pU5LPwvDgxo0V4Q7JplNwdnXS62Dt3PEjDmuxfXIM3mjZsF 
expires: 1999196123

And then just load it with:

my_hash = YAML.load File.open('/path/to/yaml/file')

my_hash['access_key']     #=> 'XXXXXXXXXXXXXXXX'
