TeslaCurl is a middleware for Tesla. It will log a curl command for each request.

The package can be installed by adding tesla_curl to your list of dependencies in mix.exs:

def deps do
  [
    {:tesla_curl, "~> 1.2.1"}
  ]
end

usage
Usage

defmodule HelloWorld do
  use Tesla

  plug Tesla.Middleware.Curl
end

Note - Plugs are executed in the order they are defined. As such, it is recommended you define TeslaCurl below other middlewares. For example, if the TeslaCurl plug is defined above the Headers middleware, headers will not be included in the curl log output.

Field Redaction

You can pass a list of header keys or body field keys to be redacted in the options, like so: redact_fields: ["api_token", "authorization", "password"]

If supplied, the redacted fields will be replaced with REDACTED in the curl command.

If a request's body is a string, you can use a regular expression with a capture group to redact the field. For example, if you were supplying Tesla with a string body that looked like this-

"<username>John Doe</username><password>horse battery staple</password>"

You could redact the password field by supplying the following option- redact_fields: [~r{<password>(.*?)</password>}]. This field will be replaced with <password>REDACTED</password> in the curl command.

Follow Redirects

If you would like to enable the flag to follow redirects by default, supply follow_redirects: true in the options list.

Compressed

For compressed responses, you can supply the compressed: true option. This will add the --compressed flag to the curl command.

Logger Level

You can supply the logger_level option to set the level of the logger. The default is :info. Must be one of :debug, :info, :warn, :error, :fatal, :none.

Here is an example of options configuration with all options enabled:

plug Tesla.Middleware.Curl, follow_redirects: true, redact_fields: ["api_token", "authorization", "password"], compressed: true, logger_level: :debug
