Laravel API cURL对Python的请求

Question

I followed this Laravel token API tutorial: http://rjv.im/post/95988160186/api-token-authentication-with-laravel-and-sentry-part . I have written the following cURL request to communicate with my API:

curl -H "X-Auth-Token:tokenhere" http://localhost:8000/account

The request works properly, and accurately returns the expected data. When I translate this to Python I receive urllib2.HTTPError: HTTP Error 401: Unauthorized

import urllib2
req = urllib2.Request('http://localhost:8000/account')
req.add_header("X-Auth-Token", "tokenhere")
resp = urllib2.urlopen(req)
content = resp.read()
print content

If I pass user credentials using basic auth instead of an X-Auth-Token, the request works as expected:

import urllib2

def basic_authorization(user, password):
    s = user + ":" + password
    return "Basic " + s.encode("base64").rstrip()

req = urllib2.Request("http://localhost:8000/account", headers = { "Authorization": basic_authorization("usernameHere", "passwordHere"), })

f = urllib2.urlopen(req)

print f.read()

Any assistance would be much appreciated.

There is something you missed in the tutorial. In the tokens table there is a column:

$table->string('client');

It is important from which client you are sending your request. I am using https://github.com/hisorange/browser-detect to detect from which client I got the request.

But for now I will just try to see User Agent. In my laravel code I just logged every request to see what's happening with the following code:

Route::filter('auth.token', function($route, $request)
{
....

  Log::info($request);

....
}

Now, Let's see:

When I use curl from command line:

curl -u user@example.com:password -X GET http://localhost:8000/account

My User Agent is

User-Agent:   curl/7.32.0

I sent the same from python using your code above, User Agent is:

User-Agent:      Python-urllib/2.7

Ah! That must be it. You have to authenticate your user at least once using Basic Auth, it will give you a token and that token is valid for only that client. In the first part http://rjv.im/post/78940780589/api-token-authentication-with-laravel-and-sentry-part of tutorial there was no such condition. In the comments I received someone posted a query on how to support multiple clients, so this example was made to solve that problem.

Apart from that, may I suggest this library: https://github.com/chrisbjr/api-guard It supports Rate Limiting, easy to integrate with Sentry. It's a bit different from my tutorial. Using my solution you can hit any endpoint using Basic Auth or Token. Using above library, only token is permitted, so there is dedicated route to generate token. Let me know how it goes.
