FitNesse RestFixture test fails to get access token - rest

Question

I have REST application with Spring OAuth2 authorization. I test it with FitNesse RestFixture test (I added token from curl response and last GET operation works successfully):
| Table:smartrics.rest.fitnesse.fixture.RestFixture | http://10.76.243.103:8080 |
| GET | /<root>/version | | | 2.2.1 |
| setBody |grant_type=password&username=test&password=test123&scope=data+compute|
| setHeader |Authorization : Basic dGVzdDo4YmE5MjRjZS0wNThhLTQ3Y2YtOGQ4Mi02ZWY1N2Y4NzdiNmQ=|
| setHeader |Content-Type : application/x-www-form-urlencoded|
| POST | /<oauth-provider>/oauth/token | | | |
| setHeader |Authorization : Bearer fd947659-cf17-4ded-b2e8-698395c201df|
| GET | /<root>/schemas | | | |
And I failed to get access token on POST operation with issue {"error":"unauthorized","error_description":"Full authentication is required to access this resource"}:
| POST | /<oauth-provider>/oauth/token | 401 | <responce> | {"error":"unauthorized","error_description":"Full authentication is required to access this resource"} |
Where responce is:

If I perfrom same action with curl utility I got access_token successfully:
curl -X POST -v -u test:8ba924ce-058a-47cf-8d82-6ef57f877b6d --data 'username =test&password=test123&grant_type=password&scope=data+compute' 'http://10.76.24 3.103:8080/parseq/oauth/token' -k

Can anyone advice me how to debug or fix it?

Answer 1

I launched tcpdump to check what exactly I send from my curl request (as descibed in Use TCPDUMP to Monitor HTTP Traffic):
sudo tcpdump -A -s 0 'tcp port 8080 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
I launched it on server machine.
I found that curl automatically added Content-Type header:
08:55:30.504594 IP <my client DNS name>.53655 > cherry.http-alt: Flags [P.], seq 1801770313:1801770631, ack 3280862118, win 67, length 318

Also I've checked what exactly I send from my FitNesse test:
08:33:36.598429 IP 10.76.243.55.39600 > cherry.http-alt: Flags [P.], seq 102:347, ack 335, win 237, options [nop,nop,TS val 859086469 ecr 41658573], length 245

Content-Length: 69
grant_type=password&username=test&password=test123&scope=data+compute
08:33:36.599047 IP cherry.http-alt > 10.76.243.55.39600: Flags [P.], seq 335:974, ack 347, win 235, options [nop,nop,TS val 41658578 ecr 859086469], length 639
And I found that Authorization header is missed in my request from FitNesse. It looks like sequential using of setHeader() methods leads to overwriting of headers. So, I changed my FitNesse test to use setHeaders() method to setup some headers in one table row (as described in How can you set headers with dynamic value in the RestFixtureConfig rest fixture.default.headers):
| setBody |grant_type=password&username=test&password=test123&scope=data+compute|
| setHeaders |!-Authorization: Basic dGVzdDo4YmE5MjRjZS0wNThhLTQ3Y2YtOGQ4Mi02ZWY1N2Y4NzdiNmQ=
Content-Type: application/x-www-form-urlencoded-!|
| POST | /parseq/oauth/token | 200 | | |
And now it works fine.
