Basic HTTP and Bearer Token Authentication

问题:

I am currently developing a REST-API which is HTTP-Basic protected for the development environment. As the real authentication is done via a token, I'm still trying to figure out, how to send two authorization headers.

I have tried this one:

curl -i http://dev.myapp.com/api/users \
  -H "Authorization: Basic Ym9zY236Ym9zY28=" \
  -H "Authorization: Bearer mytoken123"

I could for example disable the HTTP-Authentication for my IP but as I usually work in different environments with dynamic IPs, this is not a good solution. So am I missing something?

回答1:

Try this one to push basic authentication at url:

curl -i http://username:[e-mail]/api/users -H "Authorization: Bearer mytoken123"
               ^^^^^^^^^^^^^^^^^^

If above one doesn't work, then you have nothing to do with it. So try the following alternates.

You can pass the token under another name. Because you are handling the authorization from your Application. So you can easily use this flexibility for this special purpose.

curl -i http://dev.myapp.com/api/users \
  -H "Authorization: Basic Ym9zY236Ym9zY28=" \
  -H "Application-Authorization: mytoken123"

Notice I have changed the header into Application-Authorization. So from your application catch the token under that header and process what you need to do.

Another thing you can do is, to pass the token through the POST parameters and grab the parameter's value from the Server side. For example passing token with curl post parameter:

-d "auth-token=mytoken123"

回答2:

Standard (https://tools.ietf.org/html/rfc6750) says you can use:

• Form-Encoded Body Parameter: Authorization: Bearer mytoken123
• URI Query Parameter: access_token=mytoken123

So it's possible to pass many Bearer Token with URI, but doing this is discouraged (see section 5 in the standard).

If you are using a reverse proxy such as nginx in between, you could define a custom token, such as X-API-Token.

In nginx you would rewrite it for the upstream proxy (your rest api) to be just auth:

proxy_set_header Authorization $http_x_api_token;

... while nginx can use the original Authorization header to check HTTP AUth.

回答4:

curl --anyauth

Tells curl to figure out authentication method by itself, and use the most secure one the remote site claims to support. This is done by first doing a request and checking the response- headers, thus possibly inducing an extra network round-trip. This is used instead of setting a specific authentication method, which you can do with --basic, --digest, --ntlm, and --negotiate.

I had a similar problem - authenticate device and user at device. I used a Cookie header alongside an Authorization: Bearer... header.
