Escaping cli中的特殊字符

Question

I have been asked to escape special characters

I have this env file

  APP_AUTH_DOMAIN = blen.pp.com
  APP_DATABASE_URL = https://bebaeio.com
  APP_STORAGE_BUCKET = blepot.com
  APP_ID = 1:2806911447cdcd63f5564ad
  MEASUREMENT_ID = G-0W

Here . - , : and / should be special characters? The escape for them would be

  APP_AUTH_DOMAIN = blen/./pp/./com
  APP_DATABASE_URL = https://bebaeio/./com
  APP_STORAGE_BUCKET = blepot/./com
  APP_ID = 1/:/2806911447cdcd63f5564ad
  MEASUREMENT_ID = G/-/0W

Is the above correct? also what would be the escape character for https://bebaeio.com

Ps: this the error I got

We were unable to parse one of your secure environment variables. Please make sure to escape special characters such as ' ' (white space) and $ (dollar symbol) with \ (backslash). For example, thi$isanexample would be typed as thi\$isanexample. See https://docs.travis-ci.com/user/encryption-keys .

Answer 1

According to your error message, you need to use a \ (backslash) not / (forward slash) for escaping.

APP_AUTH_DOMAIN = blen\.pp\.com
APP_DATABASE_URL = https\:\/\/bebaeio.com
APP_STORAGE_BUCKET = blepot\.com
APP_ID = 1\:2806911447cdcd63f5564ad
MEASUREMENT_ID = G\-0W

Answer 2

These are bash environment variables. You can either escape special characters or quote the whole value. The latter is usually easier. Also for assignment , don't put whitespace around = .

This should work:

APP_AUTH_DOMAIN="blen.pp.com"
APP_DATABASE_URL="https://bebaeio.com"
APP_STORAGE_BUCKET="blepot.com"
APP_ID="1:2806911447cdcd63f5564ad"
MEASUREMENT_ID="G-0W"
